As everyone says a lot of money, but I don't think anyone could give you even an approximate cost as one three bedroom villa will be different in size to another.
I have a built in gas fire in the living room and a log burner in the kitchen (which so far we have been lucky enough not to have to buy any logs for
) and found with both of them it was sufficient to heat the house and we have a 3 bedroomed villa. I have oil burners which we used when we had to the winter before, but that was literally for us to huddle round for extra heat which we did not need this winter at all, I am pleased to say since it was our worst winter yet.
At the moment dreading my summer electric bill as permanently have a fan on and have used the a/c for a few weeks which up until now we have not used.
