Introducing Bosch Electronic Highflow Continuous Flow Hot Water Heater

Bosch is undoubtedly one of the leading brands of water heaters in the market today and boasts excellent energy efficiency ratings. This enables Bosch water heaters to provide significant savings on running costs daily and preserves the environment too.

In the past, most New Zealand homes have chosen storage tanks as their hot water system. Today, Bosch is changing the way households use hot water – offering the widest range of continuous flow hot water systems.

Why Choose Bosch?

The recent influx of continuous flow hot water systems provides an efficient and cost-effective alternative to traditional gas and electric storage units. If you’re building a new home, renovating, or merely replacing your existing hot water system, Bosch is the right brand for the job. When it comes to hot water systems, Bosch offers a gas continuous flow water heater to suit your every need.

Bosch continuous flow systems only heat enough water for your every need, so you’ll never run out of hot water. Your entire household can shower at the same time and enjoy hot water instead of enduring a cold shower!

Continuous flow hot water systems occupy less space as compared with traditional storage hot water units. They can easily be mounted outside or, if you want, you can conveniently install internal systems in a cupboard (flueing required).

Electronic continuous flow systems can also provide you with a precise temperature adjustment feature using a temperature controller.

Here are the advantages you will enjoy when you choose to install a Bosch continuous flow hot water system:

  • Heat water only as required
  • Never run out of hot water
  • Save money on energy costs
  • Space-saving, compact design
  • Precise temperature control* giving parents added peace of mind for their children’s safety
  • Extensive range of accessories to add to the appearance of your home

Here are the disadvantages of installing a Bosch continuous flow hot water system:

  • There is some delay before the water is sufficiently heated to the right temperature
  • More water is wasted
  • It is not suitable for households with high hot water needs

Here are a few things to consider when choosing the right hot water system for your home:

How many bathrooms does your home have?

Bosch continuous flow gas hot water systems provide hot water at the turn of a tap. However, we recognise that there are times where heavy usage occurs. For example, in busy morning times, there may be more than one shower operating at the same time. It is important to select a hot water unit with a capacity to suit your household’s needs.

A two- or three-bathroom home will require a larger system, such as a Bosch 26e.

What type of Bosch Hot Water unit is right for you?

If your home has one bathroom, a Bosch 17e or 21e may be suitable. For 2-3-bathroom homes in colder climates, Bosch recommend a larger hot water system, such as a 26e.

Is there a spa bath* or large bath installed in the home?

Bosch recommends the 26e or 32 litre unit be installed in homes with a spa bath* or large bath in order to manage the larger volume of hot water required to fill the baths.

What is the distance to the bathroom and other hot water outlets in the home?

It is most efficient to have the hot water system installed in a location closer to the outlets used most frequently such as the shower or kitchen. This helps to reduce the time it takes for the hot water to reach the outlets.

Other Accessories

When installing an Electronic Highflow system in your new home, accessories to consider include a fully enclosed recess box or a pipe cover.

Flexible Sacrificial Anodes: The Future of Water Heating Technology

Would you spend 449 including GST to increase your hot water cylinders lifespan by 10 years?

Of course! 

Imagine living in a place filled with a light cool breeze during the day, and freezing temperatures during the night. Turning on the faucets and having warm or hot water for baths, showers, washing, and whatnots is a complete comfort – the epitome and pinnacle of rest and relaxation.

In New Zealand, this isn’t an uncommon occurrence. For a country far from the sun’s rays on the equator New Zealand is definitely a cool place, abundant of rainfall and glaciers. Temperatures in New Zealand go from 10 degrees centigrade down south, and 16 degrees centigrade up north. Throughout the year, temperatures change ever so slightly!

A specific type of tank-type water heater is the Hot Water Cylinder, that uses supply water pressure and delivers hot water to showers and taps. As this type of system does not use a cold-water storage tank, it is designed for small spaces and sometimes limited access. Hot Water Cylinders are enclosed with safety mechanisms that include relief valves, thermostats, and somtimes expansion vessels.

Why You Need A Sacrificial Anode

The problem with this type of heating system is that it does not last very long at the constant pressure and heat changes it faces. That is where a sacrificial anode comes to place. This replaceable component helps maintain and control the rate of corrosion there is in the tank and is present in every water heating system. Sacrificial anodes are often made out of magnesium and attracts all corrosive elements to prevent metal breakdown.

In the span of 10 years, these anodes become very corrosive and will degrade, contributing to the damage of the heating system itself. What many people don’t know is that this anode can easily be replaced, expanding its life to over 20 years, and getting the bang out of your buck.

It should be noted that only steel hot water storage needs a sacrificial anode. It becomes a secondary type of protection to the steel in any hot water tank. Because anode rods are created using less sturdy metals than steel, the node fends off attack from minerals and other materials in your water. This is why anodes are called sacrificial.

Another thing that many people don’t know is that sacrificial anodes must be replaced every 5 years to get over 20 years of use from the hot water cylinder! The real problem now is replacing the anode in a really small, tight, and cramped place such as the hot water cupboard. Replacing this over 1 meter long component needs wide space and it should not be removed or disconnected in the cylinder, which is terribly a huge cost.

Why Use the Flexible Sacrificial Anode?

This is where the Flexible Sacrificial Anode comes into light! This type of sacrificial anode eliminates several other challenges when it comes to replacing the anode. There will no longer be a need to drain and remove the cylinders, and you will no longer have to put a hole above your ceiling for access!

This anode needs less than 250 millimeters of clearance and is very time efficient as it can be installed in an hour. Upgrading your sacrificial anode to a flexible sacrificial anode is the best choice to make, because expanding the life span if your hot water cylinder outweighs the costs of buying a new one every few years.

Where to Buy Flexible Sacrificial Anodes

Buying flexible hot water cylinder sacrificial anodes are no longer a hassle in the country. Companies like Rheem, a New Zealand staple since 1958, sell products that are at the leading edge of hot water heating technology that benefits not only residential areas, but also the commercialized areas of the country.

Hot Water Cylinders NZ invests in innovation and technology to improve your experience with hot water systems here in New Zealand. Our latest innovation allows you to replace your existing Anode without having to dismantle your whole water cylinder installation. Becuase conventional Rods are very long it is almost impossible to replace without disconnecting the entire cylinder and its pipework enabling this physically.  A flexible anode makes this possible and avoids these costs. Without much hassle our technicians will remove the degraded Rod and easily replace is with a flexible model keeping the hot water cylinder in its place which provides the same protection at a much lower installation cost.

Is Your Hot Water Cylinder Leaking? Here are 7 Possible Causes

Leaks are never planned and when they happen, the timing is always bad!

This guide will help you identify where the leak may be coming from and what could have caused your hot water cylinder leak.

Whether you use Hot Water Cylinders NZ to do the repair or not, by asking the right questions and/or providing the right information, you will save hundreds if not thousands in repairs or replacement depending on system type and size.

Cause #1: Damage Caused by External Forces

External damage may cause a leak within the hot water system. If your hot water cylinder is relatively new (7 years or less) then the probability of a leak resulting from wear and tear is low.

Some questions you may want to ask yourself are:

  • Have any works taken place on my property? This includes any renovation works etc.
  • Have I repaired or replaced a plumbing fixture? This includes minor upgrades such as replacing a tap to larger upgrades such as replacing a shower. Often such upgrades can result in leaks to your hot water system. Our specialists will quickly be able to investigate through a process of elimination to determine the cause.
  • Has local Council done any upgrades? Watercare can often upgrade public watermains introducing more pressure onto a private property. This added pressure may spring a leak within the hot water system.
  • Is your hot water cupboard often used for storage or drying laundry? It may well be that pipework has been knocked resulting in a loose connection. If this is the case, please don’t attempt to repair this yourself. You may risk the pressure blowing the fitting off which will become very difficult to isolate and will cause flooding.

The good news is that most hot water cylinder leaks can be repaired, keeping your cost low. Time is often of the essence.  If you quickly identify or suspect one of the above external forces to be the likely cause, please let us know at time of booking.

Cause #2: Recent Electrical Repairs or Element Replacement

When the immersion element is damaged due to age, electrical failure or otherwise, an electrician or Limited Electrical License holder such as a plumber will need to replace the element and/or the thermostat.

When this occurs you need to be aware of several things:

  1. Your tank has been under pressure for a long time. This pressure has been consistent but when the element is replaced the tank will “decompress” which results in the movement of all components internally, including the welded seem. Often, cylinders that have had no issues prior to this decompression will start to leak once the cylinder undergoes repressurisation. This expansion and contraction is more than enough to crack a welded seam under certain circumstances.

    We always advise consumers to think carefully about an investment that could require a full replacement a few months later. Often it’s better to make this investment into a new hot water cylinder system than into a repair that represents a third of the total cost. View our “*Is Your Hot Water Cylinder Leaking?” section for more info.

  2. Once the element is replaced, if you find a leak in the vicinity of the element, then the element seals have not been installed properly or could be faulty. This information comes in handy if you recently had your element replaced and have spotted a leak.

  3. Always make sure that your contactor replaces the element with an equal wattage e.g 2kW should be replaced with 2kW and not the more common 3 kW. 3kW elements are cheaper to purchase and corners could be cut which may end up costing you more.  A higher kW rating means more load on your existing wiring and HWC which again due to age may fail.

Cause #3: Safety Valves May Be Operating

We have some great information about cold water expansion valves. Here are a couple of resources:

Cause #4: Vacuum Relief Valves or Open Vents may be Overflowing

If you possess a Low Pressure Hot Water Cylinder then your installation will either include a vacuum relief valve or an open vent.

Cause #5: Age of Your Hot Water Cylinder

If your hot water cylinder is ageing and has sprung a leak, our recommendation is that you save any money you intended to spend on an investigation or repair. Having completed over 5,000 installations to date, our records show that 2 out of 10 repaired hot water cylinders end up being replaced within 3 months of the repair. This of course will depend on the fault, cylinder & environment, but in most cases a plumbing company will charge a fee to investigate and/or attempt a repair if you’re agreeable. It’s best to make sure that you will not be charged before they despatch a technician.  

TAKE NOTE: To attempt to repair a cylinder of this age including replacement of the element may result in unintended additional damage. Element threads are often seized and too much force will crack the internal tank. Low pressure hot water cylinders are often made of copper which is a relatively soft material. It will not take much force to cause a leak.

Cause #6: Watercare & Council Watermain Upgrades

If road works are visible from your home, then there is a high chance your home is affected. Particularly if you notice a leak during or after these works are complete and you didn’t have the necessary protection in place such as a pressure reducing or limiting valve which regulates your incoming pressure.

An increase of pressure may result in:

  • Safety valves suddenly discharging water
  • Open vents overflowing
  • Burst hot water cylinders

To add to the strain, often debris will find its way into households causing other issues such as hot water fluctuation or blockages on valves such as toilet inlet vales and hot water system valves.  If you intend to install a pressure reducing valve, it is highly recommended you also install a strainer which will isolate any unintended debris from entering your home.

 

If you would like more information about Watercare compensation for watermain leaks and processes, please visit the following article: Watermain Leaking? Here is What You Can Do.

Cause #7: Dissimilar Metals & A Failed Sacrificial Anode

Every steel hot water cylinder contains a specialised Hot Water Cylinder Sacrificial Anode. Over time they break down so your hot water cylinder doesn’t. But what happens when are fully broken down? What will protect your hot water cylinder?

Whilst this is one of the causes a cylinder may leak, you may ask your, “well isn’t it a bit late once my cylinder is leaking?” You are absolutely right! This information won’t help if your cylinder is leaking but it will provide you with some knowledge around why it may be and what you can do to prevent it from happening again.

For other faults such as electrical faults or no hot water at all, please visit the following resources:

The above is a short list of causes that apply more than others. We also come across dozens of isolated causes which we have not included due to their rarity.

If you are unsure what may have caused a fault on your hot water cylinder, why not give us a quick call and speak to our highly qualified hot water cylinder specialists?

In many cases we can identify the fault over the phone at no cost to you. Alternatively, in 80% of all cases, we are able to identify the fault over the phone and immediately advise of repair and/or replacement costs. Hot Water Cylinders are New Zealand’s #1 hot water specialists and are ready to assist 24/7.

Pros and Cons of a Rheem Stellar

img_pros_1
Pros of Rheem Stellar:
img_pros_2
• A gas water heater has faster heating compared to electric models. An electric heater takes at least an hour to heat up 25 gallons of water whereas a gas heater can heat up a 50-gallon tank. This is important if you have a large family because of the high demands for hot water.
• Another advantage of using a gas water heater is that it has potentially lower cost. Although electric heaters are more energy efficient compared to gas heaters but gas heaters make up the cost by having electricity cost more than a natural gas in some places.
• Gas heaters can still work even if there’s a blackout. Since gas heaters do not have any electric connections, this make them work even in cases of power outages.
• The Rheem Stellar is specifically designed as a direct replacement if you have a Vulcan Freeloader.
• Another important thing to note if you are using or going to use the Rheem Stellar is that, you do not have to have space indoors since this is for outdoor use.
• It is also for mains or high pressure.
• If you are using a big overhead shower or a rain-head the Rheem Stellar can still deliver enough water for you.
• For a large family, having multiple bathrooms is a must so using this product is essential since it delivers at least 40 litres of water per minute.
Cons of Rheem Stellar:
img_cons
img_cons_2
• Gas water heaters can cost a bit higher as compared to an electric heater upfront and in its maintenance and installation but in the long run, you can then make up for your expenses.
• This has a shorter life span compared to an electric water heater. Electric water heaters can last up to 13-14 years compared to a gas water heater which can only last up to 13 years.
• It has a more difficult installation process because it includes a ventilation system. If your home has no gas line or has no previous gas heater, pipes or a gas line may need to be installed.
• If there is only the two of you in the household then using the Rheem Stellar may not be the best option for you. A lot of energy is used to heat up large amount of water and your consumption is low therefore it would not be advisable to have this installed in your home.
• It is started or controlled by a pilot light which means if this goes out, you may have issues turning on your water heater.
• The Rheem Stellar is designed for large consumption of hot water; it could take up a lot of outdoor space. This could be a problem if this is located in an access way or something similar.
• Rheem Stellars can take up high amount of gas consumption. If your area has a high cost for natural gases then this could be an issue for you.
• If the whole family shower at the same time, the Rheem Stellar may not be able to answer to the demand since it does not supply endless amount of hot water.
• If you are out to work or on a holiday, the Rheem Stellar could still be consuming gas.
• Lastly, this is not available for use in LPG.
You must take into consideration that at least a quarter of your energy costs goes to heating that is why, you have to make sure that you are making the right decision when choosing the best water heater for your family. Operational expenses are not the only factor that you have to consider, you must consider also the upfront cost and the maintenance cost as well.
Rheem Stellar Stainless Steel Electric Water Heater
rheem_stellar_water
rheem_stellar_water_2
There are now two available Rheem Stellar models, which is the gas and then introducing the electric water heater. The stainless steel water heater is at least 40% lighter compared to the vitreous enamel which makes it easier for plumbers to handle, transport and then do the installation. It is also aesthetically pleasing being it is in a modern design as well as offering durability. The key features of the Rheem Stellar Electric are:
• It has superior energy efficiency which gives it a lower energy cost compared to other conventional electric water heaters.
• It has a better performance of 12-24% against the Minimum Energy Performance Standards (MEPS).
• Available in a wide range of sizes such as: 80L, 125L, 160L, 250L and 315L
• If you are located in an area where there are economical off peak tariffs then the 160L model and up is the one suitable for you.
• Long term maintenance costs and services are reduced since the Rheem Stellar electric heater does not require a sacrificial anode for protection.
• It has a 75°C maximum thermostat setting which is higher compared to other products.
• This product also has a 10-year cylinder warranty
Rheem Stellar Gas 330 Stainless Steel
rheem_stellar_gas
• It has a reduced energy costs with 5 Star energy efficiency rating.
• Its hot water capacity is up to 390L in the first hour.
• The Rheem Stellar has better recovery when hot water is needed since it has 185L of mains pressure of hot water recovery every hour and an additional 50L additional recovery through the inbuilt user-adjustable mixing valve.
• Because of its mains pressure the Rheem Stellar Gas can accommodate the needs of a large family.
• Just like the Rheem Stellar Electric, maintenance and services are reduces since it does not need a sacrificial anode for protection.
• It also has a 10-year cylinder warranty.
• Replacing a Vulcan Freeloader:
• If you have an existing Vulcan freeloader and its causing you trouble and needs replacing you will be pleased to hear that by replacing it with a Rheem Stellar, you are practically replacing it “like for like”. Only a small modification needs to made to the gas pipework (more from one side to other) which is straight forward. Other than that, the location and all plumbing can be reused to install the Rheem Stellar.

Cowboys Install Fake Hot Water Cylinder

Two elderly ladies were just asking for the removal of their hot water tank and replacing it with a tankless hot water heater when a father and son team abused the trust of their customer by conning them into putting in a fake water heater.

Michael Lucosh, 66 and his son who also goes by the name of Michael, 27 was hired to install a tankless water heater. But instead, they gave their poor victims a fake hot water cylinder. Adding insult to injury, the younger Lucosh stole checks and a debit card from their victim’s purse. Meanwhile, his father was responsible for forging the signatures and then cashing the checks, as well.

Install_Fake_Hot_Water_Cylinder

Source Article

They have been the ones to install the original hot water tank and had broken that trust from their customer by doing this senseless act.  Aside from stealing, the fake water heater was not installed properly and could become a fire hazard.  Fortunately, they have been caught by the police and are now facing charges.

How to Pick the Best Water Heater Installer Company

When picking the best installer for your needs, there are several things to look for so that you will be given the best service. One of these qualities is Professionalism.  The installer should be reliable, professional and should take his job seriously otherwise, what you will receive is a below-average service.

They should be able to reassure their clients that they can get things done the soonest possible time. And, at the same time, they should be able to provide excellent service from the start of the job up to the finish line.

Another quality that one should look for is expertise.  Even if you are not an expert on water heating installation, you will be able to know whether a technician really knows what he is talking about and then follow it through with exceptional work. This should also not just be about installing or replacing a water heater but also, they should be able to point out which part is having issues and then how to address it.

Experience is also a factor.  Hiring a company that has long-standing reputation of excellent service should also be considered.  You must first check the background of the company the technician has worked for whether they have great reviews and has been recommended by a number of people.

The experience should not be just based on the company but this should also include the experience of the technician.  They should have several references and come highly recommended too.

Another thing to take into consideration is efficiency.  The job should not stretch for a long time and if you have any concerns or questions, they should be able to provide you with a clear answer.  Jobs should be accomplished within the promised time.

Most importantly, without this, none of the aforementioned qualities is useful.  There should be trust. Trust with the company and trust with the installer.  You have to make background checks with regards to the legitimacy of the company and that they should have the proper permits and licenses.

Aside from potential clients doing background checks with the company, the company itself should conduct a thorough background check with their installers.  They should check that the references that they have provided are legitimate and that the job that they have rendered is up to the highest standards.  Not only will the investigation focus on skills, this will also include that their staff have a clear record especially since they will be working inside the homes of families.

Warning Signs

There should be warning signs that you should not ignore when you are hiring someone to do a job for you.  Some of them are as follows:

  • Too good to be true – When what goes through your mind is to question whether an offer is too good to be true, most likely it is not. Reputable companies may not be the cheapest but sometimes the cheapest ones aren’t always the best ones.  As they say, you get what you paid for. If an installer is offering you their services at a very low estimate compared to the average, this should raise the red flag.  Are they going to provide you with sub-par materials? Do their installers actually have the skills and the experience? Do you really think that they are there to provide you with an honest service?
  • Trust your emotions and Gut instinct – If you feel that there is something wrong in the picture, trust your instincts and explore further. It is always better to be over prepared, over informed than none at all.  If you don’t find anything wrong then at least take comfort in the fact that you have all your boxes ticked.
  • Time-pressure – If a company or technician rushes you to make hasty decisions then there is a high possibility that you will go the wrong way. Decision-making should not be done in a flash; you have to weigh your options, check further and listen to your gut before signing the dotted line.
  • When they won’t take “No” for an answer – A good service provider should be able to listen and understand the client’s needs and concerns, if they don’t have this then they are in the wrong field of business. As a client, if your service provider does not listen to you, then they may not be the one for you.  They should have an open mind to understand your concerns and be able to address it accordingly.

Hot Water Cylinder New Zealand has done numerous installations across the country already and because of this experience, we have developed a high level of competency that our competitors are finding it difficult in offering the same quality of service.  To keep their reputation glowing, we make sure that our team are licensed and can take care of our client’s needs from beginning to end.  We employ our own staff therefore we do not need to subcontract with others.  Thus we can reassure our customers that they can put their trust in us.

Why Hot Water Cylinder Failures Are Increasing

In an article published on Christchurch City Council, there are rising incidents of hot water cylinder failures. The report says that Christchurch’s water supply has been temporarily chlorinated, which led to the failures.

The Christchurch City Council is looking into this problem and they have determined the reasons for the breakdown of hot water cylinders.

Historically, Christchurch has been dealing with issues concerning hot water cylinder failure. Some parts of the city, such as Cashmere, have been affected more than others.

Authorities from the Christchurch City Council are hard at work trying to determine the scale and potential causes for the increase in hot water cylinder failures in the past several months.

Potential Causes for the Failures

Multiple factors may cause hot water cylinder leaking, which then requires for it to be replaced. These include: the type of cylinder, the age of the cylinder, the chemical composition of the water, whether or not there is debris in the cylinder, and the quality and thickness of the copper used in the hot water cylinder,

The City Council has been working closely with manufacturers. They have now uncovered that majority of the hot water cylinders that are breaking down are those older, low pressure, copper cylinders.

How Water Chlorination Affects Hot Water Cylinders

Some parts of New Zealand that have chlorinated water are not experiencing significant numbers of hot water cylinder failures. The reason for this is the chemical composition of water supplies around the country varies from place to place.

Auckland and Wellington use surface water or water from rivers and streams. This creates a protective film when it comes into contact with copper plumbing. Christchurch uses groundwater from aquifers.

Meanwhile, pitting corrosion that leads to pinhole failure usually happens in some bore water or underground supplies.

Hastings and Napier, for example, have bore water supplies. They have also experienced an increase in hot water cylinder failures following the chlorination of their water networks. In the Napier and Hastings area, the number of failing cylinders has decreased over the year after water chlorination was done.

Here’s What the Christchurch City Council Says

The Christchurch City Council has given this advice to people who needed to repair or replace their hot water cylinder:

“We understand that having to replace your hot water cylinder is a costly exercise and we also acknowledge that there has been an increase of hot water cylinders failing since the introduction of chlorine.

“It’s important to remember there are multiple factors as to why pitting occurs in hot water cylinders. These include: chemical makeup of the water, age of the cylinder, type of cylinder used, debris in the cylinder, and the quality and thickness of copper used. Because of this, the Council is not compensating property owners.

“We are continuing to monitor the situation and work with manufacturers and suppliers to gain further understanding. Work is also progressing on our well head remediation programme to reduce the chlorine levels in our water.”

Do You Need to Replace Your Hot Water Cylinder?

Certain cylinders are sold in areas where pitting corrosion is prevalent. If you need to replace your hot water cylinder, contact Hot Water Cylinders NZ to get the best choices for your area. Options may include stainless steel or enamel-lined steel cylinders.

Does Chlorine Affect Gas Systems or Pipes?

This is one of the more common questions that residents ask. Does the chlorine that is reacting with copper in hot water cylinders also impact gas systems or pipes?

So far, there has been no increased number of failures in copper heat exchangers in copper water pipes, gas continuous flow units, or other fittings.

Conclusion

The Christchurch City Council states, “We agree that the presence of chlorine in the water, along with the other factors, such as temperature, details of installation, and water chemistry, has contributed to the observed pitting corrosion. We similarly agree that pitting corrosion of hot water cylinders is likely to become more frequently observed.  Whether or not this extends to other copper plumbing fittings is yet to be determined.”

 

How Much to Replace a Hot Water Cylinder?

Introduction

Most homeowners have a hot water cylinder installed to take care of their hot water needs. As a whole, hot water cylinders will last for a long, long time. You will need to replace them if they leak or if you wish to upgrade to a bigger, better hot water cylinder capacity.

Replacing your hot water cylinder is fairly simple for a professional who has undergone training to do just that. However, if you’re looking to do it yourself, then beware because even though the task seems simple enough, it can become quite a nightmare fast.

If you’re looking for hot water cylinders, then HotWaterCylinders.NZ is the right place for you to go.

Hot Water Cylinder Leaking

Is your hot water cylinder leaking? The first thing to do is to locate your water meter and then turn the gate valve clockwise to isolate the leak. If you’re looking for your water meter, it is usually placed at the front section of your property – in your footpath, your shared driveway, or your garden.

What to Do?

The next step is to locate your switch board or power and look for the switch called “water heater,” “hot water,” or “cylinder.” Then, the next step is to simply switch it to the OFF direction.  This will ensure that the hot water cylinder does not run empty and burn the element out while you’re waiting for the plumber.

The important thing is don’t jump to conclusions. Ask your plumber to check your hot water cylinder. If he tells you to buy a new hot water cylinder, get a second opinion. There are instances when the anlysis might be wrong, which eventually costs you thousands when you could have had a simple fixing done. Be sure to get another plumber’s opinion and see how things go.

Why Is My Hot Water Cylinder Leaking?

There are many reasons why your hot water cylinder might be leaking. You need to ask for expert opinion to isolate the case and provide measures to fix the problem. There are many reasons why your hot water cylinder is leaking.

Repair vs. Replace

Your decision on whether to repair or replace a malfunctioning water heater should start with its age. A traditional tank-type water heater lasts for 8-12 years. An anode rod inside your hot water tank helps protect the water heater’s interior lining by attracting corrosive particles through electrolysis.

Over the years, the rod corrodes and is unable to perform its job. At that point, corrosion inside the tanks begins, which marks the end of your unit’s life. Signs of this include discolored or rust-colored water and a metallic odor or taste.

Tankless water heaters may last up to 20 years. However, they cost 2-3 times more than regular ones.  Tank leaks most often signal that a unit needs to be replaced, especially if it is more than 6-8 years old.

How Do I Know If My LPG Bottle Is Empty?

A shower running cold mid-bath is never a welcome change. And it’s just as frustrating when your heating appliance or gas hob stops without a hint, because you’re suddenly out of gas. You can stop this annoying thing from happening again if you know when your LPG bottle is running low.

Help is here as we’ll show you an easy way to check when the bottle is about to run empty – so you can keep your gas supply going.

How long does a LPG bottle last?
For a family of two adults and two children, a 45kg bottle used for both hot water and gas cooktops will typically last about 6-8 weeks. It’s a different thing if you add a gas-fired space heater.

Gas cylinders typically have a change-over regulator (reg) installed between them. Some cylinders have an automatic reg that switches from the empty bottle to the full one when the first runs out. Other cylinders have a manual regulator, which you will need to turn by hand to switch to the reserve bottle.

The change-over regulator usually has a viewing window or an indicator. When both bottles are full, the indicator will be Black, Green or Clear. When one bottle is empty, the indicator will be RED. The reg will have a change-over valve and a directional arrow. If your regulator is manual, do not adjust the directional arrow. Many people mistake it for the change-over valve, but the arrow simply indicates which bottle is empty.

It’s a good idea to regularly check the indicator on the change-over regulator, so you can call us when one bottle is empty.

How to test the level of LPG in the cylinder
One way is to pour warm (not boiling) water down the side of the bottle. Wait a few minutes, then run your hand down the side of the bottle. The level where it feels cool to the touch indicates how much LPG is left.

This is a fairly accurate method, but there’s an easier and faster way – using a LPG cylinder weighscale.

gas_bottle_scaleThis is an innovative sensing device that monitors bottled gas levels and automatically sends an accurate reading of the remaining gas in the cylinder. The weighscale is installed underneath your LPG cylinders. We can set them up for you, and once they’re there, checking your cylinders will be one less thing to worry about.

The device is also tied to a mobile app, which you can  access to get detailed daily usage reports or prompts when your cylinders need a refill. You never need to guess the gas level as there are easy to view visuals and graphs for the remaining LPG. As the supplier, we also have this data in the app, so we’ll also know when to deliver the next cylinder so you can keep your gas going without interruptions.

This works for both residential and commercial applications. For more information about this new technology, a chat or call is most welcome. Get in touch with Hot Water Cylinders NZ!

Gas Hot Water Vs Electric

The Hayman Thermostatic Storage Electric Heater made by L.T Hayman Ltd in Auckland you see is almost 60 years old!

gas_VS_electric_water_heatingIncorporated is a Satchwell Thermostat (made in South Africa) enabling the user to change the internal storage temperature. This was before our new laws around Legionnaires’ disease were passed a few years ago preventing manufacturers from incorporating an adjustable thermostat.

As in the case of our Hayman Thermostatic Storage Electric Heater, when an older tank gives up and it’s time replace it, the question each home owner should ask is, “Is it worth switching to gas?”.

To read up on some of the benefits when upgrading to gas, please visit our Upgrade to Gas section.

old_low_pressure_hwcThis blog is not designed to convince you to buy a gas product, rather point out the benefits gas will bring and, in some instances, the disadvantages when upgrading from an electric hot water cylinder.

When looking at gas vs electric water heating there are several things you will want to ask yourself, including why, when, and how much will it cost?

The following should play into your decision making:
Why do I want an upgrade to gas?
Is it Opportunity, because your cylinder needs replacing?
Is it Savings, because you believe gas is cheaper to run?
Is it Lifestyle, because want to enjoy unlimited time in the shower?

Whatever the reason may be, it’s important to know all the facts.

hwc_thermostat_adjustableOpportunity
Without doubt, the best time for an upgrade to gas is when your hot water cylinder needs to be replaced. This is simply because you are about to spend $1500+ on a replacement which could go towards a gas water heating system if all variables apply.

If you have done your due diligence and are confident gas is the way to go, then by all means upgrade to instant gas water heating.

To help with your due diligence, we have compiled the following “to do list” for you.
If you can answer all the below with Yes, then you are ready to go with gas!

  1. Are you upgrading because your hot water cylinder needs to be replaced?
  2. Do you have a single level home?
  3. Are you upgrading from low pressure to gas?
  4. Can the gas unit be positioned in a compliant manner and central to most delivery points, especially the kitchen and shower?
  5. Do you already have gas on the property or intend to go with LPG at the time of upgrade?

Savings
If you are looking at gas because you believe it’s cheaper to run, then you are right and you are wrong. Savings will fully depend on your site conditions and how your current hot water cylinder system is set up.

There are ways to make savings on an electric system without upgrading to gas including:
• Flow restrictors
• Smart controllers
• Better insulation

If your home has 2 levels or more, you may want to be cautious before upgrading to gas as pipe lag and undersized units may result in more energy use, negating any desired savings. Additionally, in many cases when upgrading from mains pressure to gas you will also experience a water pressure drop. Pressure loss with instantaneous water heating systems is very common, especially when retrofitted into the existing house plumbing.

Lifestyle
Lifestyle is one of those reasons that is hardly arguable. The home owner understands the pros and cons and is willing to make sacrifices to gain a specific desired outcome.
Some of these include:
• Longer showers
• Gas cooking
• Combination systems

Despite your motive, it is advisable to keep all the above points in mind.
Whether you are upgrading to gas or upgrading to mains pressure, one of the key factors is your property.

Before making any commitment, get a second or even third opinion. Why not speak to the hot water specialists to get advice on a solution that will not only compliment your property and desired benefits but also meet your budget!
