I would like to install an extractor fan in my utility room, since my condenser dryer makes the room very hot and damp.
Currently I already have three holes in the only external wall
1 - Boiler flue (boiler is in the utility room as well) 2 - Ventilation hole for boiler (about 20cm diameter with a dividing thingy piece of wood in it) 3 - Ducting from the adjacent bathroom (with extractor fan)As you can imagine adding a separate hole for an extractor fan will make the, already unsightly, external wall even more unsighlty.
Can I install a extractor fan in the ventilation hole or will that affect any ventilation regs regarding my boiler? Or is my only other option to make another hole in the wall?
Apologies if this is a dumb question but I want to ensure that the solution is safe.
Thanks
Charlie
