Take A Look At Our Robust Range Of Water Heater Systems

Check out our range of mains pressure, low pressure, electric, gas, solar, outdoor, wetback and heat pump water heater solutions!

Mains Pressure

The majority of modern homes in New Zealand will feature a mains pressure water heater which is normally served by a stainless steel cylinder system. There are several distinct benefits to going with a mains pressure system, one of which is that most contemporary tap-ware fixtures are only rated for mains pressure.

Choosing this kind of water heater option will give you a lot of options for picking fixtures when renovating or upgrading specific things, like a shower head or sink faucet.

A mains pressure cylinder will also give you a significant increase in shower pressure, and this is especially true in upstairs bathrooms. You also won’t have to wait as long for showers, baths and taps to get hot.

At The Cylinder Guy we offer a comprehensive selection of stainless steel cylinders and we are able to consult you on which will be best for your needs. We sell and install the leading brands in water heaters including Rheem, Rinnai and Peter Cocks.

The Rheem Range

Our selection of Rheem water heater products come in 135L, 180L, 250L and 300L sizes. Each unit is made from stainless steel with a colour-steel exterior and has connections for solar or heat pump systems.

Low Pressure

As energy costs rise throughout New Zealand, the demand for low pressure water heater systems rises with them. Since generating hot water accounts for nearly half of all your electricity bills, it’s only logical to make sure you get the most cost-effective option available.

When you replace your old system with a low pressure one you will be getting a more efficient system that will also cut down on your water usage and save you money at the same time. You’ll also get the benefits of a durable system that is built to last.

We offer a comprehensive range of Rheem hot water cylinders that we can quickly install in your home, hassle-free!

gas hot water heater


Gas water heating is popular for very obvious reasons – the water is almost instantly hot as soon as you start using it. This is great because it saves money as you don’t need to waste water waiting for it to heat up and it also rations your supply better as you are only heating when it is needed.

At The Cylinder Guy, we can help you select and install the right gas water heater solution for your home. We have broad range of continuous flow gas systems from leading brands like Rinnai and Rheem.


If you don’t have a lot of free space in your home, then it may be more appropriate to use an outdoor water heater system. The latest generation of outdoor cylinders are highly efficient in spite of being exposed to the elements and will help to free up a heap of space in your home.

The Cylinder Guy provides a diverse selection of high quality outdoor water heater cylinders from leading brands.

The Cylinder Guy believes in supporting renewable energy and encouraging people to invest in solar power solutions for their energy needs. This is why most of our selection of water heater cylinders is ‘future proofed’, with connections ready for a solar system.


We supply a full range of wetback water heater cylinder for both mains pressure and low pressure systems. We are able to help you select the right model for your specific needs.

Heat Pump

At The Cylinder Guy we know that many people are concerned about the running costs of their electric water heater systems and this is why we offer Aquafire heat pump systems that are an ideal long-term investment that will cut down on your energy bills.

When you hire The Cylinder Guy team to install your Aquafire heat pump onto an existing or brand new cylinder, we are able to help you cut down your power bill by up to a 30%. The savings are so significant because the Aquafire heat pump is 3 times more efficient than a regular electric water heater element.

This kind of system is also more environmentally friendly than a traditional electric element as it generates heat by converting the surrounding air and infusing it with the water rather than using electricity. This cuts down on the power usage of your home so that you leave a smaller carbon footprint and can feel less guilty about using your water heater.
