What is the Cheapest Way to Heat Hot Water?

Are you looking for the most efficient way to heat water? Are you struggling to choose between a gas or electric water heater? You’re not alone! Thousands of Kiwis share the same sentiment. Recognizing this problem, we thought of preparing a quick guide to discuss your options and the pros and cons of each type of water heating setup. Hopefully, by going through our discussion below, you can identify the best option for your property.

Gas vs. Electric Water Heaters

The debate between using a gas or electric water heater has been around for years. That’s because both options present varying benefits to potential users. If you’re not sure which of the two you should pick, here are the key factors you should consider when you go shopping:

  • Accessibility – This refers to the ease of using the water heater.
  • Size – When shopping for a water heating system, make sure you take into consideration the size of the tank. This way, you can increase you heating system’s efficiency and avoid producing too much or too little hot water for your home.
  • Efficiency – This aspect specifically looks into how well a water heating system operates and how much energy it uses to do the job.
  • Maintenance requirements – Needless to say, choosing a water heating system that requires little to no maintenance is the best choice.
  • Installation – The installation of both types of water heating options are straightforward. However, you may need to consider a few complications when switching from one system to another. Be sure to consider this aspect when choosing a new type of water heater.

Operational Cost: What’s The Cheapest Option to Heat Water?

Now that you know the basic factors to consider when choosing between an electric and gas heater, let’s deep dive into the operational costs involved. As you might already know, most homeowners base their decisions on the cost of running a water heater, simply because the expenses tend to add up to the monthly budget of families. In fact, water heating costs accounts for up to 30 percent of a household’s monthly electricity bill.

To help you choose between the two, here’s a breakdown of their average operational costs:

  • Gas Heater – Gas-powered water heaters come in two options. Between the two, most people opt for the gas continuous flow because of its high efficiency. On average, it costs between NZD 750 to 950 per year to run this type of heater for an small household if you have a natural gas connection. You may also use an LPG tank and pay around $850 a year. You can even reduced the costs if you have gas supply for other heating purposes.
  • Electric Heater Electric water heater installation costs are almost equal to gas water heaters. However, the running costs have a bit of difference. Notably, an average Kiwi household with three people spends about NZD 1000 a year to run an electric water heater. The cost may also fluctuate depending on the electricity rates and night tariff.

Gas Water Heating Remains the Cheapest Choice

Common Cold Water Expansion Problems. Leaky Hot Water Cylinder Valve.

Do you have a mains pressure hot water cylinder? Is the overflow constantly draining? Or the relief valve leaking water? In other words, do you have a pipe sticking outside the house maybe going into a gully/ drain that is always dripping water? If so, it will be an issue with one or both of your relief valves.

 

What is a relief valve?

A relief valve is the most important part of the mains pressure hot water system, it protects the tank from over pressurizing. When hot water is used and the element or gas fire starts up to begin the reheating process, the heat increases, and so does the pressure. In order to prevent the tank from bursting, the excess pressure caused by heat needs to be removed from the tank. This is where relief valves come into play. The relief valve will open when specific conditions are met, which is usually when the pressure increases to a point which the valve is designed to open or if the temperature increases too much

Cold Water Expansion Valve (CWE) does all the day to day reliving of pressure, the valve is fitted to the cold water inlet of the cylinder. The CWE is the first valve to relief pressure on a mains pressure system, it will be set to relieve at a lower pressure setting when compared to the TPR valve, they are designed to be the first to relieve because they are fitted to the cold water inlet, this means all the day to day relieving of pressure is through cold water, and not hot water, this in turn will save you money on power as it will not be wasting hot water.

Temperature Pressure Relief (TPR) is designed to be a secondary back up if the cold-water expansion valve fails but also relives water in the event of overheating. If your system is fitted with a cold water expansion valve, and the TPR is dripping water, that will mean there is an issue with the TPR valve and should be replaced.

Check out one of our older blogs to find out more about cold water expansion valves here and the benefits of having one if you do not have one already.

 

Importance of maintaining relief valves

There are several things that can cause issues with relief valves, and if regular maintenance is not performed, you could be left with higher water bills, higher power bills and even a flooded house in extreme cases. For this demonstration we have cut an RMC Cold Water Expansion valve in half to help show the way the valve works.

Continuous water dripping through overflow or relief drain

Debris or sediment, If you live in an area with lots of building and road works going on, or even if you have an old style water main that may be falling apart internally, this can cause large amounts of debris to make its way into your homes water supply, this debris gets stuck in seal of the relief valve will cause the valve to never be able to shut properly, this will cause a continuous flow of water, this is an issue that should be addressed immediately as the continuous flow of water through the valve will cause holes in the brass and can even cause the water to spray from the brass of the valve itself causing a flood inside the house, in some cases you may be able to avoid the need to call a plumber by simply flushing the valve on a regular basis (recommended every 6 months) otherwise the valve may just need a good clean to repair the issue.

Old, expired cartridge, with age the rubber will become brittle and will start to deteriorate, in some cases you are able to simply replace the cartridge, like with the RMC Cold Water Expansion valve, which is easily, and inexpensively replaceable, other causes could be that the return spring has lost its “springiness”, so it is not able to fight the pressure to close again properly

Hard water conditions, sometimes the water supply you get is not ideal, it may contain things that could corrode these valves or even appliances using the water in a short amount of time. If you believe this may be your issue, we recommend getting your water quality tested to ensure.

Preventative measures

How long does a hot water cylinder last NZ?

Hot cylinders have been here for a long time. They’re one of the most common forms of hot water heating system in New Zealand that’s proven to be reliable and cost-effective. Hot water cylinders tend to last for 8 to 15 years, depending on the type and quality of the unit.

However, hot water cylinders still need adequate and regular maintenance despite the expected long life. No matter what kind of water heater you have, if you don’t take care and check its condition regularly, it can spell early doom for your equipment. 

The unfortunate reality is some hot water cylinders last shorter than they should. After five years, some families might have to get rid of their water heaters. On the other hand, others might be lucky enough to keep their units running for 15 years.

Making the time to monitor the status of your cylinder makes the difference between having to buy a new heater right after your warranty runs out and being able to keep it for a few more years.

So, how can you keep your hot water cylinder running for a longer time? Here are some things you can do:

  1. Check the Anode Rod. Anode rod corrosion causes hot water cylinder failure. To prevent this, check its condition regularly, Replacing if necessary.
  2. Remove Limescale. Limescale can cause your water heater to lose efficiency. Flushing your heater with pure white vinegar will remove limescale buildup.
  3. Flush out Sediments. Hot water cylinders need annual flushing to clean out the tank’s bottom sediment.

Of course, if you’re unfamiliar with working with hot water cylinders, you don’t need to force yourself. We always recommend contacting a reputable hot water cylinder specialist like Hot Water Cylinders NZ for any service or repair difficulties.

Plumbing in West Auckland

Plumbing in West Auckland is always a wonderful experience. This client wanted their hot water cylinder upgraded to mains pressure and connected to their underfloor heating which is a relatively straightforward and stress free job. What made things easy was the location of the client’s existing cylinder.

Because the hot water cylinder was located outside it meant we were able to remove the broken cylinder and install the new one without much hassle. This is what makes plumbing in West Auckland so enjoyable. Most of the homes have their hot water cylinder situated outside, making the whole process quick and easy. It means we are able to access all the plumbing easily and have a little more space to move around.

There are also benefits for the client too. Having your hot water cylinder outdoors provides a couple of benefits. Firstly, it frees up space inside giving you another closet for storage or room to expand your kitchen during a renovation. Secondly, if your hot water cylinder was to leak, then your home would be protected as the water would simply spill outside rather than into your carpet.

If you are in West Auckland and need some plumbing done, then call the team at Hot Water Cylinders NZ. Contact us online or call 0800 832 638.

Like with all continuous flow hot water systems, in some instances you need to be aware that:

  • There may be a need to upgrade your gas pipe, which may add up to your upfront costs.
  • A small amount of water ( approx. 1-2 liters) is wasted upon initial delivery.
  • You may notice a reduction in mains pressure when when high volumes of water are used.

These are things that you must consider when choosing which of the Thermann continuous flow hot water system units you chose. Not sure? Ask us for advice!

Some factors that will play a role in what size unit you need.

How Many Bathrooms Does You Have at Home?

When turning on the hot water tap, Thermann’s continuous flow gas hot water system is immediately put into action to supply hot water. However, heavy usage can occur in your home and Thermann acknowledges that. These moments arise during the mornings, when everybody is scrambling to take a shower, hence using more than 1 at a time. This can also happen when you have guests over. When choosing a continuous flow gas hot water, it is important to keep in mind your household and select the correct size.

More bathrooms will require you to purchase and install a larger system that can deliver more, an example of this will be the Thermann 6 Star Continuous Flow at 26 ( twenty-six) Liters.

Which Thermann Continuous Flow Gas Hot Water System Is the One for You?

With homes having 1 or 2 bathrooms only, the  Thermann 6 Star Continuous Flow at 16 liters or at 20 liters is suitable but you can always get a larger model to have more capacity in future, checking the price differnce is sometimes worth it. If you have 2-3 bathrooms in your household, a larger continuous flow hot water system will come in handy, such as the Thermann 6 Star Continuous Flow at 26 Liters.

Homes with home spas or bathtubs are recommended to purchase the Thermann 6 Star Continuous Flow at 26 liters or Thermann C7 Continuous Flow, which is available at 26 liters (higher demand). These units can cater to the biggest amount of water for your needs.

Installing your unit closer to the hot water tap/outlet to be used will be efficient in transporting the heated water to the fixture you are using, limiting the time it needs to travel from the source.

Other Accessories Needed

Installing Thermann Continuous Flow Hot Water Systems in enclosures will help protect the unit. Universal Continuous Flow Controllers are also available to control the temperature of the water to what you want.

Please speak to your Gasfitter or Hot Water Cylinders NZ about fluing options.

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.

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.

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.

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.

Hot Water Cylinders Failing

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.

wet_patch_under_cylinder

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.

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.
