Heat only boiler

Also known as an open vent boiler, a heat only boiler provides both central heating and hot water through a hot water storage cylinder and cold water top up tanks. For this reason, heat only boilers need more room, but it does mean more than one tap can operate at the same time. Heat only boilers are most suited to larger homes with an existing heat only boiler.

High efficiency open vent boilers

Our Potterton and Worcester open vent boilers are all high efficiency condensing boilers, which means they recover energy normally discharged to the atmosphere through the flue. If your existing open vent boiler is an old non-condensing model, then replacing it with a newer, high-efficiency condensing boiler will not only reduce your CO2 output significantly, but also save you around one third of your heating bills.
