Unvented Cylinders

An unvented hot water cylinder holds heated water under extreme pressure, providing instant hot water the minute a tap or valve is opened. It’s completely pressurised which is why it has the name “unvented” – meaning you don’t need a vent to outside. They take up less space than traditional systems, as there is no need for a cold water tank.


Unvented cylinders are usually more expensive options than traditional boiler systems, but our team can work with you to help you decide if this is the right approach for you and your property.
