Dear All,

The sudden rush on block heater threads has got me thinking about installing one in my OM617 whilst I'm rebuilding it. I can source one locally from a USA specification car but it of course runs off 110 volts not the 220 volts we get here...

If I remember correctly the amount of energy supplied at 220V 50Hz is about the same as 110V 60Hz - something to do with the number of cycles in a given time and the area under a graph (an integration problem) - so would there be any problem in directly hooking up something simple like a (110V 60Hz) block heater to a 220V 50Hz supply?


Any electrical engineers in the house?

I've just revised my opinion on this and I don't think the energy is the same - perhaps I'm getting confused with the reason why the 110V 60Hz and 220V 50Hz were chosen - that's something to do with lethal voltages I think...
