Guys thanks for answering, am feeling pretty upset by all of this, to have had a modicum of sanctuary that has now gone is quite distressing, I feel tired and wiped out after 3 nights of this and am finding it hard to think straight. The way our house is structured ( ie quite small) there is no other room to escape to, and I can now feel the effects of this new motor not only in my entire bedroom but also in the living room downstairs.I have used the LF and RF meter on my machine and it does not register any higher than normal readings, although my machine i think is quite a basic one, so I find it hard to understand what exactly has gone wrong. I spoke to the Gas board who didn't really have any suggestions to make apart from getting an electrician in to check for dirty electricity. I have put layers of aluminium foil on the inside of the door which have made negligible difference, I really don't know what to do next. Stewart you mentioned carbon grounding ( ?) could you tell me what exactly that is and how it works?

If it is a magnetic field from the motor you can use mu metal but that is expensive. Multiple layers of steel will reduce it as well. I use simple heating duct sheets bought at a hardware store such as Home Depot. Are there wires that you can put snap on ferrites on?
