Unvented Hot Water Cylinders

In certain applications where combination boilers are not a suitable option, an unvented hot water cylinder can be installed to provide hot water to your home. Unvented cylinders provide mains pressure hot water to your taps and showers, providing the ability to have multi showers running simultaneously without the need for a separate booster pump.

Benefits of unvented cylinders

These cylinders also offer a far greater flow rate of hot water, satisfying the demand of more than two bathrooms where a combination boiler would not cope.
