RBHM recommend a wide range of high efficiency unvented cylinders, which offer excellent hot water comfort for properties with a stored DHW supply.

What is an unvented hot water cylinder?
An unvented hot water cylinder is a pressurised system which is fed directly from the cold mains water feed and therefore can deliver hot water at mains pressure, which is great for improving the performance of your shower and bath.

Unvented cylinders don’t require a cold water storage tank, which is ideal if you are pushed for space as well as offering more flexibility when siting the cylinder.

The water can either be heated directly via an immersion heater or indirectly via the central heating system, solar thermal technology or other renewal energy such as heat pumps and biomass.

Why choose an unvented cylinder?
High performance due to unrestricted mains pressure at hot water outlets
A perfect replacement for low efficiency copper vented cylinder installations
Stainless steel, delivering durability
Siting flexibility – no need to locate the cylinder directly underneath a cold water storage cistern
