The guys at Hot Water Shop changed my leaking low pressure hot water cylinder to a mains hot water cylinder. They were fantastic to deal with. Free quote, turned up on time and house was left clean and tidy with a new mains hot water cylinder. Very easy to deal with. Highly recommend.

Great team - they removed the existing hot water cylinder and replaced it, connected us to mains, and also replaced the shower mixer for us. Everyone I dealt with was great, and I'd highly recommend them for their reasonable prices and good service.

From start to finish I could not be more happy with my experience with Hot Water Shop. While the pricing was really competitive, it was the fact the whole team were super friendly, professional and helpful, that made them really good to deal with. If you need a plumber, I cant recommend them highly enough, they did a really good job.

A new cylinder can also, of course, mean better water pressure with more hot water available. Upgrading your hot water cylinder is a great time to consider the size cylinder that works best for your home, if your family is expanding, or you are looking at getting tenants into a property – the hot water needs may change quickly.

When space is of the essence, the size and location of your hot water cylinder are very important.

Low Pressure systems are still quite common in New Zealand, especially in houses that are 30 years or older. We have a huge range of sizes available and we can arrange a custom build if you have a tricky size that needs replacement. If your budget allows for it we would recommend upgrading to Mains Pressure for improved performance.

One of the most common cylinders in NZ, the mains pressure systems gives you more hot water faster and won’t drop pressure when running two taps or showers. Plus mains pressure will give you ultimate flexibility in tapware choice and future upgrades, such as adding Solar or a Heat Pump to reduce energy use.

Modern cylinders are now more efficient and better insulated than ever before. And now we have a range of electric hot water cylinders that can be installed outside your home – perfect if you are doing a renovation and want to free up space for a kitchen, laundry, or linen cupboard. Talk to us today to find out if an Outdoor Cylinder is right for you.

Hot water cylinder systems are used to provide hot water in a home. To install these systems, it’s important to hire a professional team (like us!) who has the tools and knowledge needed to do the job correctly. The installation process involves selecting the right type of cylinder and removing the old hot water system and installation of the new cylinder – often in a new location or outdoors. 

Regular maintenance is critical to ensure that your hot water cylinder system operates efficiently and safely. Without proper maintenance, your system can become less efficient, resulting in higher energy bills and reduced water pressure. Additionally, a poorly maintained system can lead to leaks and potentially damage to your family home..

Keep your hot water cylinder working for longer


To maintain your hot water cylinder system, it’s important to check the pressure relief valve every six months to ensure that it’s working correctly. The valve is responsible for releasing excess pressure and preventing the cylinder from overheating. It’s also important to inspect the cylinder regularly for signs of corrosion or leaks. Flushing the cylinder once a year can help prevent sediment buildup, which can reduce efficiency and damage the system over time.

By following these simple tips and hiring a professional plumber for regular maintenance, you can ensure that your hot water cylinder system operates efficiently and safely for years to come.

Advantages of Hot Water Cylinders


Hot water cylinders are known for their reliability. They are simple and, if maintained properly, can last for many years.

A ready supply of hot water

Hot water cylinders are able to supply hot water to multiple fixtures at once. This means that multiple people can use hot water at the same time.


Hot water cylinders are often more cost-effective than other types of water heating systems. 


Frequently asked questions

Depending on which option and size you choose, price can vary greatly. Some that are more expensive to buy are designed to save you money in bills, whereas cheaper models to buy may not be so savvy on economic settings and rack up larger bills. Always discuss all of these options, benefits and pitfalls of each model to understand what to expect from your new hot water cylinder, at the time of installation and in the long run. Outdoor cylinders can cost anywhere from roughly $1,600 all the way to $6,000 depending on the model and features. Mains pressure and low pressure cylinders start in the low $1000s, some models being even cheaper to buy. Solar cylinders are a tad more expensive due to the solar panels required to buy with it in order for it to work efficiently. Your specific requirements will rule some cylinders out and shine others in a favourable light – so talk to the experts today about what you need and get a free quote.

When you need hot water, be it for a shower or for your kitchen sink, that hot water has to be coming from somewhere. Hot water cylinders are as they sound, a large cylindrical tank somewhere in your house that provides hot water to every tap. These hot water cylinders vary from make to make, from the pressure to size and between power sources. The cylinders themselves are made from steel (newer models) or copper (more traditional models) and operate in a similar way to an electric jug. New Zealand manufacturers offer different power sources between cylinder makes, from electricity-powered hot water solutions to gas, solar, heat pumps and wetback systems. All of these cylinders are regulated by a thermostat to meet New Zealand hot water heating regulation standards.

Hot water cylinders work by filling the tank through a bottom inlet with cold water, and heating that water gradually. As the water heats up, it rises to the top of the tank, ready to be used via the top outlet, by any tap or shower in the household that is turned on and requests hot water. This process continues all day and night, providing you with the hot water you need – whenever you need it. There are varying degrees of availability and quantity of hot water depending on which pressure system you are on, but the functionality is almost always the same.

Low-Pressure Hot Water Cylinders

Still common in older Kiwi houses, low-pressure hot water cylinders deliver adequate hot water and pressure for a small family or people who do not need a lot of hot water on demand. Low-pressure cylinders are suitable for traditional style taps and low hot water use. By regulating the hot water in this way, you save money on heating bills and there is very little waste – making it more eco-friendly and economical.

Mains Pressure Hot Water Cylinders

The most popular of hot water cylinder solutions, mains pressure cylinders are attached to your mains water – and pump out a huge amount of hot water fast for large households, households that run multiple taps or showers at once or where there is a higher demand for reliable pressure and temperature. Modern taps, showers and mixers are more compatible with mains pressure systems than any other due to the high amount of heated pressure required to make them function as designed.

Outdoor Hot Water Cylinders

For space-saving within the walls of your home, you can opt for an outdoor hot water cylinder. These cylinders are built to weather all kinds of climates and are more efficient than they’ve ever been before. To free up that space in the linen closet or kitchen, choose an outdoor cylinder for hot water you can enjoy but won’t encroach on your living spaces. These are perfect to install during a renovation, or straight from the original build.

Solar Ready Hot Water Cylinders

Solar ready refers to a small port that allows for your cylinder to be converted to solar power later down the line. Solar-powered cylinders gain their energy from solar panels on your roof, taking the natural power of the sun and converting it into energy to heat your hot water. An eco-friendly alternative to hot water cylinders otherwise powered by electricity or gas.
