Is Your Hot Water Cylinder Pilot Light No Longer Working?

Did your gas water heater suddenly stop working? Chances are the pilot light, which ignites the gas burner on your hot water heater, has gone out. If it has, you can try re-igniting it according to your water heater label. If the pilot light keeps going out, there are a number of potential problems to check.


  1. A bad thermocouple

The thermocouple allows gas to flow to the burner when it senses heat from the pilot. If it detects an unlit pilot, it automatically turns off the gas as a safety precaution. The thermocouple may stop operating if it is dirty, bent or damaged.

Dirt and grime can be cleaned off using a piece of sandpaper. If the thermocouple is bent far away from the pilot, you can simply bend it back to its original position, making sure it is close enough to the flame. The pilot light should appear blue in colour. If there is no clear sign of dirt accumulation or bending, then the device may simply be broken and needs replacing. This can be checked using a multimeter which tests the voltage coming from the device.

In theory, replacing a bad thermocouple is easy and only takes a few steps:

  1. Turn off the gas valve – do a quarter turn such that the handle is at a right angle to the pipe.
  2. Unscrew the nuts on the gas, thermocouple and pilot lines.
  3. Turn off the shutoff valve
  4. Remove the gas control and pilot light burner assembly
  5. Use a flat blade screwdriver to pry the spring clip on the thermocouple head and pull out the old thermocouple from the bracket.
  6. Install the new thermocouple (this should be the same type, size and length).
  7. Slide the burner assembly back in and reattach all three lines to the control valve.
  8. Relight the pilot, following the instructions carefully
  9. Reset gas control and refit access cover.


It is important to test for gas leaks, especially when replacing a thermocouple. When the gas burner turns on, soak a sponge in a 50-50 water/dish soap solution and wet the screw joints – air bubbles will indicate a leak.

A word of caution: before cleaning or cleaning, make sure to turn off the gas and wait for the thermocouple to cool to the touch. There will be a faint gas smell when you remove the gas lines, but this should dissipate within seconds. If the smell lingers, you should call your gas utility.

Working with gas carries a lot of safety risks, which is why we don’t recommend doing this operation yourself. It’s always best to err on the side of caution. Also, some hot water heaters also have a closed burner chamber that is difficult access, so it’s better to just call in a registered gas fitter.

Another thing is that, in some older models, the thermocouple can’t be replaced due to the unavailability or discontinuation of spare parts. Here at Hot Water Cylinders, we replace thermocouple on any brand, with the exception of Rheem.

  1. Flex tube problems

If the thermocouple checks out, you might want to check for flex tube issues. Sometimes, this tubing gets kinked in places, which disrupts the gas flow and prevents proper pilot operation. Unkinking may resolve the issue. But if it fails, you’ll likely need a new flex tube.

  1. Dirty pilot tube

If the thermocouple isn’t to blame, try checking the pilot tube. There might be dirt and grime buildup that obstructs the flow of gas. Unlike a broken thermocouple, a filthy pilot tube is much simpler to fix.

To start the process, turn off the gas and wait for the pilot to cool. Then, take a needle and clean the tube making sure to take out any blockage. After cleaning, turn the heater on and check if the pilot light will ignite. If it doesn’t repeat the process until everything works fine again.

  1. Main control valve issues

When all other issues are ruled out, the last thing you could check is the main control valve. It is rare for main control valves to go out but it is still possible. If you get a good result after testing the thermocouple using a multimeter, then a bad main control valve might be the culprit.

  1. Gas regulator issues

The gas regulator basically works by opening to let higher-pressure gas into the system and quickly shutting down when the “downstream” pressure reaches the desired level. The moving parts in this device are constantly in use and, hence, are prone to wear and tear. If the gas regulator is worn out, you’ll notice the pilot on your water heater, furnace and other gas appliances snuffing.

Other possibilities include a leak that is causing the burner to extinguish, an ignition that needs replacing or intermittent low gas pressure due to system fluctuations.

It’s a tall list of things to remember for the uninitiated, but a licensed gas fitter will have the expertise to find and fix the issue quickly and safely. They will also keep you from making errors that might make your warranty void.

If you are not able to light the pilot on your water heater, contact us on 0800 429 546 or use our advisor.

The Importance Of Seismic Restraints

Do you want this to happen to your cylinder?


If you don’t, seismic restrains are an excellent choice when installing your cylinder.

What are seismic restraints?
Seismic restraints for hot water cylinders are steel straps used to keep a hot water cylinder in place, preventing it from falling during an earthquake. They are affixed by screwes and washers of a certain standard to the wall framing around the cylinder. Hot water cylinders are heavy items, with a 135 litre cylinder weighing around 170 kg when it’s full of water. If there are no restrains, this is quite a lot of weight to be flung around in an earthquake, not to mention if you have an even bigger one. It can also damage other items such as pipes which are connected to it, and cause a flood.

Along with this, NZBC B1.3.2 standard requires building elements (including storage water heaters) to be adequately supported including support against earthquake forces. The method illustrated in Figure 14 is acceptable for water heaters up to 360 litre capacity. Where fittings and pipework are attached to the water heater through the supporting platform or floor a 50 mm minimum clearance shall be provided between the fitting and the support structure. 6.11.5 An alternative acceptable solution for securing storage water heaters against seismic forces is given in Section 203 of NZS 4603.


If you are getting a new cylinder installed, make sure that it comes with a seismic retraint kit!

Retrofitting a seismic restraint kit
If you already have your cylinder installed and are not looking to replace it anytime soon, it is possible to retrofit seismic restraints to your exisiting cylinder. However, this is more complicated than installing with a new cylinder, since access behind the cylinder is required. If this is something you would like to do, it is best to contact us to discuss the job.

Hot Water Cylinder Experience Is Key

We all want to get the best value for our dollar, so we try to get the best prices from suppliers whenever we can. Having said that, the best price doesn’t always give you the best deal. Lower prices may reflect low-quality goods and services which may not be the most cost effective option in the long run. So while price is important, a better gauge to use when choosing a supplier is experience.

This is especially important when you’re buying big-ticket items like your hot water cylinder. Only an experienced supplier will be able to help you choose the right product that will heat your home efficiently and economically. Here’s why

Hot_water_cylinder_experience_is_keyExperience means better quality

“The more you do, the better you get.”  If you’ve been doing the same thing for years, you tend to get better at it. Hot Water Cylinders NZ has been in the business for years now, and we’ve installed over 1,000 units in the last financial year alone. This makes us the hot water cylinder supplier and installer with the largest experience in New Zealand.

In all our years of operation, we have learned all the tricks of the trade and found the best systems that provide the best value for our clients. We know that what works for one household may not work for another, so we make sure to provide tailored solutions every time.

There is a right hot water heating system for every installation job. We design our systems based on clients’ individual hot water usage and budget. Our goal is to ensure efficiency and economy, regardless of the brand. We are not partial to one brand, because we know all brands have their own good qualities and features that may work for different types of home. We do endorse brands like Rinnai and Bosch, but only because we’ve already proven them to be reliable and effective. Still, we stock all kinds of hot water cylinder systems from different brands to give our clients a comprehensive selection.

Experience means better service

Customer satisfaction is the hallmark of our service. Our referrals and repeat business are the best testimony to the quality of our work, and we work really hard to ensure our clients only have good things to say about us.

Experience taught us that a strong relationship benefits both parties. So we’ve made it our commitment to build and sustain true partnerships with our clients, making every effort to deliver the best service possible.

Experience also means better value

Even with new hot water heating technologies entering the market, we are not quick to upsell our clients to the latest product if it’s not in their best interest. In fact, there is often no need to replace your hot water cylinder, unless it’s already too old or inefficient.

Since a heavy price tag does not equal quality, we don’t push sales on the most expensive system in our range. Nevertheless, our experience taught us that some of the most reliable hot water cylinders will cost a bit more than the average systems. So you might find that spending a bit more on a cylinder today will give you greater savings in the long run. We always advise our clients not to look solely at the price but to weigh out the features and functionalities among their options, in order to make a smarter decision.

Because we know the right strategies for all kinds of installation, we can help you avoid common mistakes that can be costly to repair. For instance, some new installers does not know how to size the cylinder correctly, which results in an inefficient system that costs more to run. With experienced hot water cylinder installers like us, you’ll have your steady supply of hot water running in no time! Our systems are built to last and come with comprehensive warranties for your peace of mind.

Experience means compliance and safety

As experienced installers, we are highly familiar with applicable codes and regulations. We have learned all the things that could possibly go wrong with a hot water cylinder installation, so rest assured we also know the ways to avoid them.

Our installers are certified plumbers and gasfitters with decades of combined experience. And our systems are all tested for safety.

Homeowners also have a role in ensuring the safety of their hot water cylinder. Although the unit will remain hidden in a utility closet or basement, it needs regular maintenance for safety purposes. We make sure to educate our clients about safe operation and upkeep, particularly of certain components such as the pressure relief valve, vents and the temperature control.

Experience means expert advice

If you can’t decide between a vented and unvented cylinder, solar hot water cylinder or gas-powered water heater system, we’ll explain everything you need to know without the complicated jargon. With us, you won’t be left in the dark. If you’re not yet familiar with your options, we will explain how each hot water heating system works, what type of fuel is best for specific hot water usage, how much they cost, and what the benefits and disadvantages are. We also educate our clients about heat-loss figures, reheat times and insulation to give them a better idea of how efficient hot water cylinders should work. We’ll guide you in choosing the most suitable system for your budget and heating needs, and make sure the system is future proof to give you maximum return on your investment.

At the onset of every project, we encourage our clients to voice out all their questions or concerns. We are always ready to give a straightforward answer. In our experience, problems sometimes arise due to non-communication, and these mistakes can blow the client’s budget out of proportion and also reflect badly on our service. To prevent this, we make sure our clients are well informed before they sign a contract with us.

Whether you are buying a new hot water cylinder or replacing your old unit, you may contact us us for unbiased advice or a no-obligation quote through these numbers: 0800 4 CYLINDERS or 0800 429 546.

Milky Tap Water: What Are the Causes and Solutions?

So you turn the tap for a glass of water, and you notice that the liquid coming out of it isn’t clear but milky. But then, after a few minutes, the milky water starts to clear up until the cloudiness is all gone.


What could have caused the milky appearance, you might ask? Well, there are a number of possible reasons for this:

  1. Air bubbles

Milky water, also known as white water or cloudy water can be caused by air bubbles that get trapped in the pipes. When water-soluble gases such as oxygen, chlorine, hydrogen sulphide, carbon dioxide and others enter the mains supply, they create air locks or air pockets in the plumbing system. As these gases are carried along the pipes, they get dissolved in the water. When you open the hot water tap, the pressure is released and the dissolved gases spurt out into millions of tiny air bubbles. This is what gives your hot water the white, milky appearance.

All main supplies contain a small amount of air, but a tear or damage in the pipe may pull in additional air. A change in the water pressure may also be to blame. An increase in pressure causes excessive air to get trapped in the pipeline. This can happen if:

  • Your home’s plumbing system and heater use the well system.
  • There is disturbance in the water distribution pipes, such as when utility companies switch from one well source to another.


Milky water is also common when the weather is cold. As water passes through the pipes in your home, it is mixed with oxygen. When it’s cold outside, more oxygen bubbles get into the water, hence the cloudy water effect.

If the water is left to stand for several minutes, the dissolved gases will start to separate and the cloudy effect will go away. This reaction is very much similar when you pour carbonated drinks into a glass.

  1. Your water heater’s anode

If water from your hot tap is excessively cloudy and generally stays that way, the issue may be with your water heater itself.

The anode rod (factory installed) in your hot water cylinder is there to inhibit rust by maintaining an invisible film of free hydrogen on the entire surface of the heater. The anode is placed where rust initially forms – in the water tank. It acts as “sacrificial metals” which draw the metallic ions in the cathodic area and keep them from going into the solution, protecting the tank against corrosion. This is most common in water heaters that are less than one year old. It disappears over time.

When water from ALL of your hot water taps turns milky, it could be a sign that your anode needs replacement. The good news is replacing an old anode rod is relatively easy and inexpensive.

  1. Sediments

Sediments such as sand, dirt and tiny particles from rocks in the ground can get into your water supply. This can happen when there are drilling activities nearby.

It’s easy to tell whether the milky appearance of your hot water is caused by air bubbles or by tiny particles. Wait for the water to clear up and watch. Air bubbles tend to rise to the water’s surface, while sediments tend to sink into the bottom or do not clear at all.

Like air bubbles, the presence of particles in the water does not make it harmful but aesthetically unpleasant.

  1. Methane Gas

It’s highly uncommon but not impossible. This problem can occur in areas where gas and oil wells are nearby. Methane is a flammable gas, so having it in your water source can pose problems. It is hard to detect since it is odourless unless the water also contains hydrogen sulphide. In addition, methane acts the same way as air bubbles –they also rise to the water surface and escape into the open air.

The usual fix for water containing methane gas is installing an aerated tap, which permits the gas to dissipate faster. The aerator must be vented to the open air to prevent the risk of fire or explosion.

Is the water safe to consume?

You may notice a difference in the smell, taste and overall aesthetic of your water. But as off-putting as milky water may look, it is completely harmless and safe to drink or use.

However, please note that cloudy appearance that is another colour other than white (i.e. brown, yellow or green) can indicate presence of bacteria, metals, minerals or other contaminants. This is often the case when the cloudy water effect does not clear up after some time. Cloudy water of this kind may have adverse health effects when consumed.

What can you do?

If water from all of your home’s taps appears cloudy, the problem could be from a pressurised water system. If only a single tap produces cloudy water, then the issue is with that fixture alone. Cloudy water from a hot tap can be an indication of a problem with your water heater.

Milky water caused by air bubbles or dissolved gasses can be resolved with aerated taps. Sometimes it cannot be fixed entirely, but aerating the water significantly reduces bubbles.

The cloudy water effect should not last longer than 24 hours. If the milky appearance of your hot water bothers you, you can:

  • Keep the taps running until your water runs clear.
  • Check with your neighbours to find out whether they are having the same issue. If such is the case, it is advisable to notify your water supplier of the problem.

If the situation doesn’t clear up itself, it is advisable to call in Hot Water Cylinders NZ to check whether things look normal or you need to take further steps.

Rinnai Discontinues the iHeat Ducted Heating Range

Rinnai Corporation, the leading makers of tankless gas water heaters in New Zealand, announces the discontinuation of their iHeat central heating products dues to “cost increases of key internal components.”


The Rinnai iHeat is a ducted heating system that uses hot water to warm and circulate air, providing fast central heating to the entire home. The system is designed to operate in conjunction with a Rinnai Infinity continuous flow water heater. It has been touted as a healthy central heating option as it maintains the air quality and reduces the likelihood of allergens entering the home. The iHeat system is defined by its discreet installation and high energy efficiency (up to 80 percent).

Despite its wide public reception and positive reviews, the Rinnai team has decided to stop its production as a result of their ongoing product rationalisation, citing the following reason:

“Cost increases of key internal components has made producing the iHeat uneconomical.”

iHeat products will remain on the market until the end of December this year, or until stocks have run out. Nevertheless, Rinnai reassures iHeat users that spare parts will remain available and all warranties for iHeat will be honoured over the long term.

An Alternative to iHeat

With the iHeat phased out, Rinnai offers an equally efficient and powerful central heating system: Brivis ducted heaters.

Brivis is the leading brand of gas ducted central heating solutions in New Zealand, and has only been recently owned as a subsidiary of the Rinnai Corporation. The brand supplies a complete range of highly efficient ducted gas central heating products specifically designed for the NZ conditions.

“The addition of Brivis to the Rinnai range means that a more complete heating range is now available,” said the Rinnai team. “In most instances where an iHeat has been specified, Rinnai can supply an equivalent Brivis central heating solution.”

Brivis heaters may not have some of the “smarts” found in the iHeat, but their performance is highly comparable. They are also extremely efficient, with the range offering 6-Star rated systems such as the StarPro 6.

Some of the noteworthy features of Brivis ducted heating systems include:

  • Up to 16 fan speed settings that better match air volume and flow to your home
  • Zero ChillTM soft fan that prevents cold drafts on start-up
  • Automatic gas modulator that maintains the temperature level using a minimal amount of energy. You can set your home to a comfortable temperature and leave the system to keep it steadily heated at that level.
  • Ability to create up to four distinct zones
  • Ability to set the system to automatically turn on/off so you come home to a warm house or limit heating when not needed
  • Simple and easy to use programmable controller with both manual and auto modes
  • Compact, splittable and weatherproof units that ensure ease of installation.

More information on the Brivis range can be found at To enquire about an installation, please contact our home heating specialists on 0800 4 CYLINDERS or 0800 429 546.

Rinnai Discontinues INFINITY Composite Recess Box

Rinnai Corporation, leading manufacturer of tankless gas water heaters, announces the discontinuation of its INFINITY™ composite recess box (R1406).

The composite recess box was introduced as an affordable alternative to the metal recess box designed for housing some units from the INFINITY™ range. Composite products are known for being incredibly strong and corrosion resistant, making them perfect for external applications. Despite this, the Rinnai NZ team explains that demand for the composite recess box is low, hence their decision for its discontinuation.

Meanwhile, the metal recess box will continue to be available.

INFINITYTM Metal Recess Box

The Rinnai metal recess box allows you to virtually hide your INFINITYTM unit, pipe work and power supply into a cavity, ensuring a smooth and neat finish to the job.

It allows a continuous flow gas water heater to be partially or fully recessed into an external wall, unlike the composite recess box which can only be semi recessed. The composite recess box is also not suitable for fire rated walls. These are probably why the metal recess box proved to be a more popular option.

Constructed of folded galvanised steel and powder coated white, the metal recess box can easily be painted to match or complement the exterior cladding. It is suitable for the following external Rinnai INFINITY gas water heaters:

rinnai_composite_recess_box_discontinuedR1405 recess box:

  • A-Series: A16-A26 (current range)
  • VT16-VT26 (discontinued)
  • XR16-XR26 (discontinued)
  • V16-V24 (discontinued)

R1407 recess box:

  • EF24 (current model)
  • HD200 (current model)
  • HD250 (current model)
  • XR32 (discontinued)

Installing a metal recess box

The INFINITYTM metal recess box is ideal for new builds or major renovations as it needs to be installed during the framing stage, i.e. before the internal linings, claddings or building wrap are applied.

The Rinnai continuous flow gas water heaters are designed for external installation, and thus your metal recess box must be located in an above ground, open-air situation. The area must have natural ventilation, where flue gases are safely expelled and rapidly dispersed by wind and natural convection.

Generally, it can be mounted on any vertical structure with water and gas connections and enough clearance for the pipe work. You can install it on an outside wall below eaves, balconies and other areas, but you might want to reconsider siting it near bedrooms since water heaters inside a recess box operates at a slightly louder level than units located externally. In most cases, the metal recess box is better located near the kitchen where there is a high demand for instant hot water.

In addition to general clearances, you need to consider your local building codes regarding this type of installation. To make sure your INFINITYTM water heater is compliant and installed properly, consult a licensed gasfitter familiar with the system prior to installation.

How Water Cylinder Theft And How To Prevent It

Did you know that hot water cylinders are a target of theft? To most people, the thought of someone stealing your hot water cylinder would be ludicrous. But it is no joke, and hot water cylinder thefts continue to rise.

hot_water_cylinder_stolenCylinder Thefts And The Resulting Problems
The main target of hot water cylinder thefts are older low pressure hot water cylinder units which contain a large amount of copper. Copper fetches a significant price over metals like steel at scrap metal merchants, as high as $7.40 per kg, which means a 180L cylinder could be worth as much as $74, placing these cylinders containing copper at the top of the list for thieves.

However, the theft of the cylinder is not the only problem. When these thefts occur, the thieves are not exactly overly concerned about what state the property is left in, and as such usually take the quickest route to removing the cylinder which involves quickly sawing or ripping pipes, letting the cylinder drain onto the floor and then removing the cylinder by force. This causes a substantial amount of damage, not only to the pipework and the area surrounding the cylinder, but extending into the rest of the house due to the flooding.

Primary targets have been older homes which are under renovation or construction and are easier to access, not occupied and are likely to have an old cylinder about. Boarded up unused houses and houses which look to have been unoccupied for a while (such as when the occupants go on holiday) are also common targets.

However, due to these thefts, it is required by law to produce ID when selling scrap metal to a metal dealer. This makes it more difficult for thieves to sell the scrap once they’ve taken it, and acts as a deterrent to minimise the amount of theft that is happening.

How To Protect Yourself
There are steps you can take to minimise the risk of your hot water cylinder being targeted by thieves. One of the best steps you can take is to make your property look occupied, even if you are going away. This could involve having a friend clear out your letterbox regularly, leaving an old car parked in the driveway or leaving a light or two on to seem like someone is home. Thieves usually target vacant homes when going for cylinders, so if it looks like someone is home it will minimise the chance that they will try your home. Always have a friend or family member check on your home regularly to ensure it is secure while you are away.

Other measures you can take include making sure your cylinder is securely strapped into its installed position. This makes removal much more difficult, and is likely to put off opportunists. For home owners with instantaneous gas water heating units installed outside, there are brackets and cages which you can install on the unit to make removal next to impossible.

Luckily, modern mains pressure hot water cylinders are usually either stainless steel or enamel, which makes them much less of a target for theft than the older low pressure copper cylinders. While this does not guarantee that your home won’t be targeted, it certainly means that the reward is far smaller and will make the break in much less worthwhile.

Always Report Theft
If you have been a victim of theft, it is always important to report it to the police, even if you believe the damage is insignificant or you believe that they won’t be able to help. Reporting crimes helps to paint a bigger picture, allowing the police to see how prevalent the problem actually is and treat it as a priority. It can lead to an investigation which could result in the apprehension of the culprit. It will also help with insurance claims, as a police report can help with the process of filing a claim.

We Have Hot Water Cylinders for Sale!

Gas heaters can be found in many homes in Auckland. These heating systems often use hot water cylinders to ensure copious amounts of hot water are stored and available on demand. There are a number of things to consider when choosing a hot water cylinder for your home, i.e. capacity, efficiency, cost effectiveness and suitability to your boiler system.

Types of Hot Water Cylindershot_water_cylinders_for_sale

There are two main types of cylinders:

  • Unvented Cylinders. These work off the cold water main pressure, providing hot water on demand. Since they operate without a feeder tank, unvented cylinders free up space in your loft and allows you to install the cylinder anywhere around your home.

Generally constructed with top quality stainless steel, unvented cylinders have long lifespan and high durability with manufacturer’s warranty that range up to 25 years.

Since they operate at higher pressure than traditional vented units, unvented systems require additional safety features and need to be installed by boiler specialists. This adds up to the installation costs.

  • Vented Cylinders. These copper tanks are fed cold water from the mains feed and use gravity to drive water through the pipes to the home’s heating system. They are suitable for use with standard heat only boilers. A vent pipe connects the cylinder and the cold water in the header tank.

Vented hot water cylinders are less complicated than vented systems, which means they are easier to install and maintain.

Other types of hot water cylinders come in both vented and unvented systems:

internal_gas_hwc_for_saleDirect Systems

In direct systems, an internal element (usually an immersion heater) heats the water in the cylinder directly. The heated water is fed out the top of the cylinder and supplied to the outlet (i.e. a shower or a tap) on demand.

Direct cylinders are an electric only option and are normally used when no central heating is installed, such as in flats and apartments.

Indirect Systems

As the name suggests, indirect cylinder systems heat water indirectly via an external heat source such as a gas boiler or solar thermal. An immersion heater is typically fitted as a direct backup or supplementary heat source. This ensures you have a steady flow of hot water even when your boiler is broken.

Indirect gas heaters particularly heat up and recover faster, making them a cost effective option. If you want to save cash without compromising performance or efficiency, you can always switch to gas cylinders any time.
