Electric Water Heating

A Kiwi Classic

A staple in many Kiwi homes, the hot water cylinder is among the most popular ways to heat water for use in the home. These cylinders tend to last for a long time, so many people don’t think about replacing them until absolutely necessary. While it’s great to have a system that works for so long, you may not be benefiting from advances in electric water heating if you are running an older cylinder. If you live in an older house with a cylinder just as old, it may be time to upgrade.

Cylinders are typically made from stainless steel, enamel or copper. The cylinders fall into two categories – low pressure and mains pressure cylinders. Low pressure cylinders are usually made from copper and are most commonly seen in older homes. They are relatively cheap to install and last a long time, usually upwards of 20 years. Mains pressure cylinders have a higher water pressure and are made from ceramic-lined steel or stainless steel.

Things to consider when choosing an electric water heater

It is important to decide on what water pressure you want when buying and installing an electric water heater, as mains and low pressure cylinders each have their benefits and drawbacks. Our knowledgeable staff members are happy to guide you in this process so you can select the best type for your needs.

If you own a cylinder that was installed before 2002, we advise that you have a special hot water cylinder wrap installed around the cylinder and the first meter of piping to prevent unnecessary heat loss.

Commercial applications

When large volumes of hot water are needed, a heavy-duty hot water cylinder may be the best option. These are available in a range of sizes and can be plumbed together to allow for higher flow rates than a single unit can provide. Climate can provide you with a customised solution specific to your needs.
