boru 400i

Jcanty85

Hi all,

Recently had a boru 400i 7kw inset stove installed, fully lined chimney with the back of the stove fully insulated. The room is relatively small (14ft square with 2 external windows and a double door into the kitchen, fairly good level of insulation throughout). Ive tried every combination of timber and coal fuel as well as every combination of primary and secondary controls and am still disappointed with the heat from it, with a roaring fire you would comfortably sit directly in front of it. I think I might be loosing a lot of heat up the chimney as it has to be going somewhere..does anyone have one of these stoves or had similar problems??

If you are burning timber and coal together, that isn’t helping. Never burn timber and coal at the same time.
When the stove air intakes are closed is the fire still burning strong? If yes there is an excessive chimney draw due to your location. This would not be a stove problem.

Hi, thanks for your reply. I actually did a fraught reading on it today, with everything closed and a small fire lighting it was reading 40 (pascals I think) and apparently anything over 20 is big so I think there is a big draw alright however the rep even said that it should still be throwing out heat. With the controls closed it does still burn strong I.e a lot of flame, is there anything that can help with this do you know? Also excuse my ignorance but should the controls not still be able to cut down the fire regardless of draught? does it not still need to pull air from the room? Thanks

The air controls can only stop the air from the room entering. You have air entering from an open chimney through the stove flue also. This is permanently open for exhaust gases to escape. Unfortunately due to your house location the volume of air in the chimney is too high. You need to install an anti down draught Cowl or extend the height of your chimney. I find the H Cowls the best but they are trial and error.

sorry I should have mentioned that there is already an anti down draught cowl fitted. Is there any alternative that could work do you think? heard of something called an aerocowl but have no experience with this.. thanks for your help
