I would ask to see the electricity bills for the last couple of years. CHF350/month max, but what is the average?

We have a small house 128sq metres heated by gas. The cost is approx CHF1100/year - most of the use coming through the winter months.

Electric heating using a heat pump to heat and for hot water is efficient, but electric cables under the floor to heat and oil-filled radiators are not.

As other poster have pointed out, in Switzerland at least, thanks to hydo-electric schemes electricity is relatively green and supplies are more secure and prices likely to rise less then gas or oil.

In the end it seems to me you will know your local housing market and thus can decide if such a house can be re-sold, this has always been my criteria for buying - or is the electric heating going to be a problem...
