We have the return vent (cold air intake?) for our central heating system in the corner of our lounge / dining room. We really want to stick a low side-board / tall boy over it, but I wanted to know how much clearance you think we should leave. Is just two or three inches enough?
More importantly, what are the risks if we dont have enough clearance? What is the worst that can happen? Will it just be that the heating works inefficiently?
Any help / advice is much welcome as we really want to cover what is an ugly corner of the lounge.
