-ERRNomenclature Dotan.  Fuses aren't rated in watts, but amps, and the 
voltage they can successfully blow and interrupt the circuits current flow at 
in the event of a total crowbar with several thousand amps flowing until the 
fuse can interrupt it some milliseconds later.

Secondly, that certainly sounds like a fire looking for a place to happen.

Who is the legal authority responsible for that?  Here in the US we have 
pretty well enforced codes that would be grounds for legal action in the 
event some old, grandfathered construction such as you are describing should 
malfunction and start a fire.

That is probably a radiated noise problem, where better cables in the audio 
system might reduce it.  If the lights dim so that you can see it whebn the 
heater comes on, that would indicate undersized wire, and when all that is 
added up, I think she should be changing her address to a more modern 
building for her own safety.

A dose of luck would be handy too.
