Vents and firestove

[Reprnow]

Hi,

A lot of cold air is coming into my kitchen/living room from a large vent installed by the previous owner on the ground floor (see picture). As he also added a firestove around the same time, I presume this was done to comply with building regulation. Could you confirm that this is the case? If so, is there a way to reduce the cold airflow while keeping the firestove?

Many thanks.

The regs require any stove over 5kW to have a room vent or to be fed combustion air from outside.
Under that, natural draught is deemed sufficient but it’s always a good idea to do a spill test with a smoke bomb, and of course a CO alarm is vital.
You’ll get one hell of a draught with that set up!
Clearview stoves have a good air admittance system, straight from underside to the outside.

Probably doesn't need to be that big.

So looking up close the pipe behind the vent is actually smaller and measures around 120mm in diameter. This seems more in line with the latest building regs. The kitchen has gas hob installed and the firestove is situated some 6m away from the vent. The installation has HETAS cert so I don't want to mess too much with it. The easiest option appears to purchase an anti draught external vent. I could also get a hit and miss although it would need to be changed back when I come to rent or sell for building reg purpose. I intend to use the firestove sparingly. Any recommendations?
