Open vent systems are normally connected to two tanks in the loft. A small ‘feed and expansion tank’ supplies water to the boiler and the radiators. A larger domestic cold water storage tank provides the cold water feed to an open vent hot water cylinder.
Although replacing the boiler and linking it to an existing open vent system is an option, most people opt to remove the tanks from the loft and to install a sealed system boiler or a combi.
