Housewarmer 44 back boiler air intake

[camerart]

Hi,
I have a Housewarmer 44 back boiler from 1986, which will be updated later.
The air intake is from the room, so it must suck in cold air into the house.
What I would like to know is can I add an air intake from the floor cavity instead(Timber floor)? If so how big should the hole through the floorboards be?
Cheers, Camerart

If it’s ducted to outside and the correct size and access for inspection,,so not much point as still getting air from outside.

Hi C,
It's not ducted, it's a back boiler where the air is from the room.

Air vent must be ducted and of the correct size to outside

housewarmer 45 i take it ,
then it needs a vent of 73cm2 and if floor completely open under neath boards an not compartmentalized the same in outside wall if outside wall has several vent already if they add up to minimum 73cm2 then that is acceptable.
But you will still be getting the same cold air drawn in ,
Also take air from under your floor it cannot be open to any other properties attached

I'll check all of that, I can cut a 100mmx100mm square out of a floor board.

True, but not extracting heat out of the house.

It isn't.
Thanks, C
