Rick K Posted December 18, 2022 Share Posted December 18, 2022 We are planning putting in a log burner and will have MVHR installed. Am I right in thinking that it is important to have a double lined flue so that combustion air can be brought in via the flue? Link to comment Share on other sites More sharing options...

A double lined flue is a twin wall flue for insulation and a must when it goes through a ceiling and a room above. What you need is a "room sealed" stove that usually has an attachment on the bottom for an inlet hose, mine is 80mm diameter but others may be different and you connect that to a duct through the wall at low level behind the stove, or you can if you have a suspended floor duct it in from the ventilated under floor space. Make sure your chose stove takes both primary and secondary air from the duct, we found some that took secondary air from the room so not true room sealed.
