I've just had my boiler serviced after moving into our house about 6 months ago.
The service failed because apparently the system isn't ventilated well enough and I need to ensure that there is a permanent vent to the outside from the room the boiler is in (the hall). It needs to be 50cm2.
Can anybody offer advice on whether I need to get a builder in to fit the vent for me if it is easy enough to do myself? (I'm a bit concerned that I'm essentially making a hole in the side of the house). Also can anybody recommend where I get the vent from, or any replacement vents as the house was left in quite a state and I would really like to replace them all.
Yeah it can be done by a competent DIYer, go to a gas/plumbing store and ask for a black hole vetilator, the vent has to have a duct across the cavity to prevent it from becoming blocked.
Easiest/neatest way is with a core drill, but expensive if you don't already have one. Alternatively, draw around the duct with a pen or pencil then drill all the way round the pencil line and knock out with hammer and chisel.
