I have some audio-visual gear (principally a video projector) mounted on a high shelf, just below ceiling level, in which position it's in danger of overheating unless I can increase the ventilation. Directly above the ceiling is an unused part of the loft: if I install a vent grill (or even more than one) in the ceiling, will that provide enough of an escape route for the heat? In this section of the loft the floor is insulated but not the underside of the roof, and the loft gets very hot in warm weather - will this prevent the hot air from the electronics rising away from the shelf? Obviously, I would remove the insulation from above the grill or grills.
I suppose the ideal arrangement would be a fan-assisted duct route leading through the roof to the outside, but I'd prefer something simpler if possible. I assume that anything would be better than the present arrangement, which is a real hot-air trap.
It's one of those niggly things which I should have thought of at the design stage, but didn't.
Thanks in advance for any thoughts.
