Gas water heating has become very popular lately, especially continuous flow systems which deliver endless, mains pressure hot water without the need for a large cylinder inside the house.

There are three types of typical gas water heaters used for residential water heating.

1. LPG continuous flow: If you don’t have Natural Gas at the house then this is a good alternative to achieve mains pressure water heating. Like the Natural Gas option, this also provides you with endless, high pressure hot water for less running than a mains pressure cylinder by about 15%. This option is ideal for situations where there might be intermittent demand for hot water such as at a beach house or holiday home. One benefit of continuous flow water heating is that you’re only heating on demand and so when you happen to be away, there is no power being lost as with conventional electric storage cylinders. Our total installation package is a turnkey solution which includes removal of the old cylinder, new electrical connection, gas fitting, plumbing, auto-change-over regulator etc. We even arrange for the LPG bottle delivery for you!

2. Natural Gas continuous flow: If you have mains gas already connected to the house from the street then this is a great option for your water heating. Not only will it give you the benefit of full mains pressure, but you’ll enjoy endless hot water so no worries about running out! You will see the benefits of a reduced energy bill since Natural Gas is about 30-40% more energy efficient than a standard electric water cylinder. Finally, you will also free up space inside the house which could be utilised for storage etc. If you are replacing an old, indoor gas cylinder and wish to go to an outdoor califont or continuous flow system, then you will need to locate where your gas meter is on the property as this will have a direct impact on the cost of installing continuous flow. Basically if your gas meter (typically a white box) is too far away from where you wish to locate the califont, then it may be more practical to stay with a cylinder. This is due to the fact that we have to upsize the gas pipe from the meter to the continuous flow unit in order to feed it a higher volume of gas and so the further the distance, the higher the cost to install. This option requires an electrical connection to be installed outside for the ignition. We take care of this and also removing your old cylinder all within one fixed price.

Natural Gas storage cylinders

3. Natural Gas storage cylinders: These can be used inside or outside and have the added benefit of not needing and electrical connection as they have a built-in pilot light for ignition. This means you will still have hot water even if there is a power outage which is always a welcomed relief. These cylinders are becoming less popular due to the cost, the space they take up, and the fact they still have some heat loss as with any storage cylinder. They are however a good option if your gas meter is not conveniently positioned to upgrade to continuous flow. Call one of our consultants today to find out if this the best option for you.

If you have any hot water problems and need help selecting and installing a new cylinder – head to our website today!

Having access to hot water is an essential element of any household. You need it to cook, clean, take a shower – and plenty of other things. Because your access to hot water is important to you, it only makes sense that you’d want to select the most reputable installer you can find.

Having an installer you can trust to secure your hot water is vital and saves you a lot of hassle down the road. You don’t want to be caught up in a crisis because your system wasn’t installed properly. A failure in your hot water system can cause all kinds of trouble, so make sure you’re happy with your choice of installer before you have any permanent work done.

The following are a few points you should consider before you select your hot water installer.


Experience is always an important factor to consider when having something installed in your home. What’s most important is making sure that your chosen installer is properly qualified and well-equipped to do the job.

Don’t be afraid to ask qualifying questions, even if it’s just to test their knowledge, as a true professional will be happy to answer them for you.


Hot Water Cylinder MaintenanceTransparency and honesty are attributes that are extremely valuable when choosing any kind of service provider. Make sure you choose a company that lays out the facts clearly and concisely without trying to mislead you or change the topic.

If the installer isn’t being clear or answering your questions properly, it’s probably best not to go with them. Having someone who is straightforward and to the point can save a lot of stress and frustration down the line.

This is particularly true when discussing costs. Some companies are purposefully vague in order to conceal their hidden costs. Finding someone who is transparent about pricing can make budgeting much easier for you.


As your service provider, the company who installs your heating system should be able to answer questions or concerns you have about the installation process or their product.

It’s understandable that you’d want detailed information about what’s going into your home and the installer should be eager to address any concerns you have.

Range of products

If you have a particular type of product in mind, it’s important that you check out the range offered by your installer to ensure that it or a suitable alternative is available.

It’s a good idea to do some research on the products they provide and gain an understanding of where they stand in the market.

Guaranteed satisfaction

If your hot water installer has guaranteed satisfaction for their workmanship, it can save you a lot of stress. Having that guarantee lets you know that they are confident in their quality of work.

This gives you peace of mind, especially knowing that if problems do arise, you can simply call them to sort things out. Looking at past testimonials and reviews is a great way to discern if the installer is reliable or not.

Here at The Cylinder Guy, we almost exclusively recommend and install the Rheem and Rinnai stainless cylinders as they do not require the sacrificial anode used in vitreous enamel cylinders. This means you don’t have to remember every 5 years to change the anode, as nobody really does, so you have the best, maintenance-free, long lasting cylinder available today.


Hot water systems are essential to your everyday life, so it is important that you maintain them well. We rely on hot water systems for comfortable showers, cooking our meals and washing – all activities that are hard to go a day without.

Taking good care of your hot water system can save you a lot of stress in the long term as it can help prevent issues from arising when you aren’t equipped to deal with them.

There’s never a convenient time for your hot water system to break down, so proper maintenance is always essential. Taking preventative measures, such as the ones below, can help give you some peace of mind.

Keeping tabs on your sacrificial anode

Most hot water systems will have a sacrificial anode, which is a metal rod constructed from aluminum or magnesium, with a layer of zinc.

A sacrificial anode protects your hot water system by attracting any impurities in the tank water so that any reaction and rusting is directed towards the metal rod rather than the inside of the tank.

Having a sacrificial anode greatly increases the life and functionality of your hot water system, so it’s important that you remember to replace it.

On average, your sacrificial anode should be replaced once every 5 years and remembering to do this simple bit of maintenance can extend the life of your hot water tank significantly.

Checking up on the temperature and relief valves

The temperature and relief values are safety measures for your hot water tank. These valves will automatically vent hot water from your tank if the internal pressure or temperature is getting too high.

Having a precautionary measure like this is incredibly important as your tank could potentially explode (yes, explode) from too much internal pressure or heat expansion. These valves act as an emergency measure to prevent the worst from taking place.

Your temperature and relief valves should be checked every six months, although you should always refer to the manufacturer’s instructions just to be safe.

How to check your valves:

You can check that these valves are in working condition yourself by testing the flow of water from your valve. Lifting the valve handle should expel hot water from the pipe, while closing it should stop the flow of water.

The water expelled should be very hot, so it is essential you are wearing the appropriate clothing for your protection. Hold the end of the pipe away from you, and wear closed shoes and gloves.

If it doesn’t seem like the valves in your hot water system are working as they should, you should call your plumber for a closer inspection. These components should also be replaced around every two years.

Call your plumber for a checkup

timaru-beach-nzCalling your plumber for a regular checkup is the best way to ensure the maintenance of your hot water system. The replacement of your sacrificial anode and valves shouldn’t be attempted on your own and is best left to an experienced professional.

Hiring a plumber to perform a routine check-up will ensure that everything is operating as it should so you can enjoy hot water all-year-round!

Always the first consideration when searching advice and solutions for Water Heating systems is who to call? The Cylinder Guy is the number one expert when it comes to all things hot water.

“We offer affordable, superior and efficient services for hot water cylinders, gas water heating, heat pump water heating sales and installation,” says Chris Rankin, Managing Director of The Cylinder Guy.

Boasting more than 10 years of experience in a competitive industry,  The  Cylinder Guy will offer all the options, different price ranges and unrivalled advice on the benefits of each option.

The second consideration will be to assess the best brand option. Although there are many different brands it often pays to stick with the most popular. The two leading manufacturers are Rheem and Rinnai who have a big reputation when it comes to hot water heating.

Some companies that install these products have a devotion to one brand or the other which can drive prices higher. “Send us your current quote for the same cylinder installed as ours and we will always better it,” says Rankin.

The third consideration will be whether to take the cheap and easy option which will incur a smaller cost in the short term but will inevitably cost more in the long run resulting from inefficiency or when the system fails.

The option which The Cylinder Guy would recommend would be to buy a heat pump water heater which works in a similar fashion to the way that air heat pumps warm up a room.

Heat pump water heaters can save you up to 65% off your current hot water heating bill.

The Cylinder Guy Van


If you want a simple and cost-effective solution that will give you better energy efficiency, more hot water or higher water pressure, then The Cylinder Guy will always explain in layman’s terms what’s right for your individual situation.

Of the several options available, hot water heat pumps are by far the most energy efficient option. They work by extracting free, thermal energy (solar) from the air rather than using an element thus saving a huge amount of electricity (up to 65% savings compared to the electric element).

This information is not always forthcoming from some plumbers who prefer to go with more traditional options, which may not always be in the best long-term interest of the customer.

“Commonly plumbers will fit hot water cylinders that are vitreous enamel, known for premature, internal rusting and as a result can cause water damage to properties,” says Rankin.

The Cylinder Guy highly recommends stainless steel cylinders which are ‘future-proofed’, meaning that they have solar and heat pump compatibility, last longer and come with a 10 year warranty.

corroded-pipesWhile corrosion and leaks to water pipes and hot water cylinders can be caused by a number of things, it is widely understood that chlorinated water can contribute to the issue. The compounds in chlorine react with copper, steel and plastic polyethylene pipes in varying degrees potentially causing premature bursts or leakage.

The practice of chlorinating water has been around since the early 1900’s in some countries, in New Zealand we are lucky enough to have had many years of chlorine free water supply and in fact several water supplies around the country remain untreated (Christchurch is currently the largest populated area). 

In recent times however, there have been calls for mass chlorination particularly after water contamination issues in Havelock North. Although it is obvious clean drinking water is a necessity, chlorination of the water supply has proven to be somewhat problematic for hot water cylinders and plumbing fixtures and fittings.

Things To Look Out For

While avoiding chlorine is difficult where water is mass treated, it is important to understand the additional potential for degrading of pipes, fixtures and fittings and hot water cylinders in order to pre-empt future failures. Here are a few things to keep a look out for.

  • Pipes, plumbing and hot water cylinders over 10 years old in towns and cities with chlorinated water supplies
  • Copper piping or fittings (anything dating around 1960’s and 70’s is particularly problematic)
  • Visible evidence of corrosion around hot water cylinder valves
  • Pin hole leaks in calcified pipes and joiners
  • Hard water (naturally high levels of calcium) is likely to intensify corrosion issues
  • Discoloured water or blue-green stained sinks, drains and baths

The Causes Of Corrosion

Corrosion in household piping or hot water heating systems and the rate at which it occurs can usually be associated with one or any combination of the following factors.

  1. PH Levels. Copper piping systems in particular are prone to damage if the pH of the water is under a certain level. The protective barrier of the pipe gets damaged which leads to a more rapid rate of corrosion.
  2. Temperature. The hotter the environment the pipes and fittings are exposed to, including the temperature of the water can also contribute to increased corrosion.
  3. Chemicals. Naturally and not so naturally occurring minerals and impurities in water can increase corrosive levels in different ways. For example high levels of calcium in water leads to a calcification build-up in pipes and fittings and chlorine introduced into the water supply has been known to accelerate the corrosive action of both metal and plastic plumbing fixtures.
  4. Oxygen. Oxygen naturally degrades metal resulting in rust. Whether it is in pipes, hot water cylinders, cars, buildings or anywhere else for that matter, rust is gradual and inevitable.

The Effects Of Corrosion

kitchen-tapThe cost of corrosion can be expensive; it can impact your health, waste money, and damage other household fittings. Leaks that go unnoticed due to corrosion can prove expensive and even result in the need for the building to be completely re-plumbed. Corrosive water can impact:

  • Hot Water Heaters. Decreasing the efficiency and potentially causing premature failure.
  • Household Plumbing. Corrosion can cause premature failure of household plumbing and plumbing fixtures.
  • Taste And Appearance. Elevated levels of metals leaching from the pipes can impact the taste and appearance of the water (reddish coloured water or green-blue stains are most common).
  • Toxicity. Prolonged consumption of contaminated water with elevated levels of metals, such as chromium, lead, zinc and copper, has been known to cause a wide range of health problems.

It is strongly recommended that homeowners have household water tested regularly (approximately every 2 to 3 years) for evidence of corrosive materials and toxicity. Ignoring corrosion or simply hoping it isn’t happening is not a good idea. The professional team at The Cylinder Guy can help you repair or replace any hot water heating issues you may have and help you avoid corrosive issues.
