ᐅ Wood-burning stove with controlled ventilation system, central vacuum cleaner, and kitchen exhaust hood

Hello,

we are building a timber frame house (KFW55 standard) and want to install a wood-burning stove in the living room.
We also have a mechanical ventilation system with heat recovery (Vallox ValloPlus SE 510), a central vacuum system (Fawas), and a kitchen exhaust hood (we plan to keep the current one, which is currently set up as an exhaust system).

How can all of this work together without smoke being pulled back into the room from the stove? It seems the stove is already sealed, but when rekindling, the stove door is opened, right?

Do I need to convert the kitchen exhaust hood to recirculation mode?

Thanks for your advice,
Thomas

Hello Thomas,

where will your new wood stove get its combustion air from? Will it draw air from the living room, or is it supplied independently from the room air, for example through the chimney (air supply duct installed in the chimney)?

Is the stove certified according to DIBt standards?

I would recommend converting the range hood to recirculation mode, at least for energy efficiency reasons.

In any case, the final decision on this matter will be made by your local district chimney sweep.

He would also be a good contact to consult beforehand on this topic.

Regards,

Dirk

You need to ask your local chimney sweep, not us. Each chimney inspector has a slightly different approach, and ultimately, they have to approve it.

Yes, of course he has to inspect everything afterwards. I just didn’t want to appear completely unprepared when talking to him...

Hello, tommo!

It depends on the power of the range hood and should ideally be tested while it’s running. You’d be surprised how much air a range hood actually pulls when it’s at full power. In some cases, the range hood may need to be linked to an opening, for example, a kitchen window might automatically tilt open via a motor when the range hood is running at its highest setting.

Best regards,

Fresh air duct installed in the chimney.

It will probably be a Hark fireplace.

Does anyone have experience with Hark?

Thank you,
Tom
