The new BS8303 standard (Installation of domestic heating and cooking appliances burning wood and solid mineral fuels – Specification) just recently published now gives the green light to stove installations where there is some form of mechanical extraction in the same room. But only if the stove has DEAS (a Direct External Air Supply) which effectively makes it a room-sealed appliance and – most importantly, only if the appropriate worst case scenario spillage tests have been successfully performed. This is where all of the home's mechanical extraction (including that in bathrooms, en suites, tumble dryers etc) is turned up full to create as much depressurisation in the room where the stove is installed to see if it adversely affects the potential updraught and the safe performance of the flue and stove. DEAS availability is listed in the stove specifications on our website and, of course, if you need any advice on this type of installation talk to us or your Hetas installer.

Stoves with direct/external air connections do not necessarily have to be expensive. The popular Hi-Flame Alpha 1 and Graphite 5 stoves are both available with a direct air box, they are also Defra approved and SIA Ecodesign ready.
