Hi guys. I wonder if a Corgi-registered engineer could help?
I have a 10-year old Ferroli Combi boiler in our house (it was fitted years before we moved in). When I had it serviced (for the first time - I've only been here 2 years!) I was told it needs more ventilation. It's housed in a full-height stone cupboard in the kitchen in the centre of the house (so the flue can go straight up and act like a chimney - it used to house an old air-heating boiler). Because there is no outside wall this means I have to add additional ventilation to the kitchen. The kitchen is ventilated (but not enough).
Anyway, while I do need to add ventilation I'm not happy in adding extra draughts into the kitchen. I've been pondering this for a while but I think I've come up with a solution that I'd like to confer with an expert. Can I use the under-floor ventilation directly into the cupboard? This would mean removing a couple of floorboards and boxing it up (so it's flush with the kitchen cupboards and just under the door - there's an air grill in this space already).
Any advice will be greatly appreciated. Hop it all makes sense!
