I have a newly fitted Ideal combi boiler. I'd like to enclose the boiler in some way, partly for appearance, and mainly for noise - it gives out a roughly 500Hz hum that seems to come from the pump. This has a strange effect round the house - it seems to get everywhere. The installer tells me it's all working within spec, and the noise isn't unusual.
Should I be looking at mass (18mm MDF say?), any design tips etc? It's too big (need 1m high, 40cm depth) for a standard kitchen cabinet. Besides which I'd like something more likely to suppress the noise.
Thanks, Rob
