1.How much do hot water cylinders cost to buy and install?

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!

2.What is a hot water cylinder - how does it work?

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. 

3.What kinds of hot water cylinders are there to choose from?

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.
