Stove ventilation

Cavanjack

I am in the process of pricing a stove with an external air inlet for an airtight house. Do I still need a vent in the wall in this room? Some fitters say the regs say yes others say no. Can't seem to find the info on the regs. Thanks

Is the stove 'room sealed' ?

Yes you need a vent in the room with the stove.
Regardless of whether it is room sealed or not.
It's not logical but it is what the building regulations state.

This has been covered here before.

With mvhr, a Nox/co2 sensor, internal stove air supply & an actual room seal stove (where no air is drawn from the room or can escape to the room) no vent required.

These stove are expensive and there are very few on the market.

Thanks for replies. It's a Charnwood cove 8 we were thinking of installing. Can't find the info if it's room sealed or not. I will try and contact them today.

CJ best contacting the vendor and asking them. What little I know if it is room sealed stove it requires an external air supply, but worth verifying, normally 100mm Wavin (well that's what I was informed).

I have been trying to figure this one out also.

I have spoken to reps of several main suppliers of the stoves - they have said that the regulations state the need for a vent in the wall in addition to the under floor vent to the stove. They say it will work without the wall vent but they are not committing to actually advising you to do it. I guess there is a major health and safety issue here. It seems impossible to get a straight answer.

I guess you need a wall vent "just in case" but then how is the house supposed to be airtight then? Or how is the heat recovery supposed to work If there is a vent in the wall?

I feel your frustration!
