I've been told I need better underfloor ventilation (there's no
ventilation at the back of the house, just the front).
We are doing some refurbishments so it's as good a time as any to rip
the floor up and put a couple of snorkel vents in the back wall.
And i'm blocking up a fireplace and apparently supposed to vent the
chimney. As it goes against the grain to send hard earned warm air up
the chimney I thought of venting the space under the floor into the
unused chimney instead.
It seems like a no brainer to me.
only possible downside is that it increases sub floor heat loss which
may be an issue if the floor is poorly insulated
We're in the process of covering it with 25mm polystyrene 'boards' and
T&G Caberfloor, so should be OK.
