Hot Water Cylinders

Enjoy reliable hot water on demand with our range of hot water cylinders – ideal for both your home and commercial buildings alike. Hot water cylinders are well-insulated tanks designed to store and supply hot water wherever it’s needed. Available in various sizes to suit your needs, our range of hot water cylinders means you can have hot water for taking showers, doing the dishes, and washing your hands whenever needed.

Unvented & Vented Hot Water Cylinders

Cylinders are manufactured in two different styles – unvented cylinders and vented cylinders. An unvented cylinder works off the mains water pressure to feed into your hot water system. An unvented cylinder is the type you will find in your loft. Also known as a “gravity-fed hot water system”, these cylinders use gravity to supply hot water throughout your home.

Indirect & Direct Hot Water Cylinders

Separate from vented or unvented types of hot water cylinders, you can also choose between direct or indirect cylinders. This describes the method by which the water is heated inside the cylinder.

Direct hot water cylinders heat the water inside via two immersion heaters. The one on the bottom of the cylinder heats the water to temperature while the other heater maintains it ready for use.

The other type of hot water cylinder is the indirect type. Indirect cylinders will be equipped with either a copper coil or airlock inside (depending on the type of heating system you have) and a thermostat attached to the outside of the shell. When the thermostat requests for the water to be heated, existing hot water will be pumped through the inside of the cylinder, passing the heat through to the water, which is then pumped out to wherever you need it.

Is it worth replacing hot water tank?

If your hot water tank is eight-years-old or older, it’s probably worth replacing it with a new one. Technology is constantly evolving, so you’ll most likely find that newer models are more efficient.

How much does a hot water tank cost?

Depending on the size and model, a hot water cylinder can cost anywhere between £900 and £1,500.

Which is better: copper or stainless steel hot water cylinder?

Both copper and stainless steel have their advantages. Copper is a really efficient heat conductor, which enables it to deliver quick hot water whenever you need it but it is susceptible to corrosion and isn’t as well suited to resisting high pressure. Stainless steel on the other hand is much more corrosion-resistant and works better under pressure so may be the better choice.
