What types of cylinders are available?

Cylinders come in a range of types and sizes. Below is a list of the most common cylinder types available and information about each one to help you decide which type of cylinder is best for your space or home. We always recommend speaking with a trained specialist before purchasing your cylinder.

Unvented Cylinder

An unvented cylinder is a tank that stores hot water and allows it to pass through taps and showers when you need it. 

Unvented cylinders are directly connected to the mains water supply, offering the benefit of a high-water flow rate, which in turn helps to boost the performance of showers and baths installed in your home. Unlike vented cylinders, unvented cylinders do not require a feeder tank and therefore offers a convenient and space-saving alternative to heating the water in your home.

As the system is a sealed system, unvented cylinders are also much less likely to become contaminated as the water moves from the cold-water tank into the hot water system.

Vented Cylinder

Vented hot water cylinders rely on a feeder tank to provide it with mains fed cold water. This water is then heated and is distributed to the hot water outlets (i.e. taps, showers) as part of a gravity led system. Vented cylinders tend to be used alongside regular boiler installations, whereas unvented cylinders are commonly used with system boiler installations.

Copper Cylinder

Cooper cylinders are manufactured from copper and cocooned in a foam insulating layer. Copper cylinders are great at retaining heat, making them the perfect choice for heating, and storing hot water in most domestic properties.

Copper cylinders are available in either direct or indirect. The type of copper cylinder you'll need - direct or indirect - will depend on whether you need the water in the cylinder to be heated 'directly' by the cylinder itself or an external appliance such as a boiler or solar panels. In an indirect cylinder, the water is heated by the boiler. Whereas with a direct cylinder, the water is heated by electric elements known as immersion heaters.

Heat Pump Cylinder

Heat pump cylinders give a robust and sustainable solution to support heat pumps.

It is a well-insulated tank that stores water after it has been heated through your boiler system. It is then kept at the perfect temperature ready for you to use when needed. This way you do not need to constantly run your heating system for hot water.

Heat pump cylinders are ideal for homes with two-plus bathrooms with the need for constant hot water. If your property has low water pressure then a heat pump cylinder is the perfect choice to support the flow of water to the shower, a hot water cylinder ensures that your water is always delivered at the right temperature.
