We are strongly considering renting an apartment in a house in a small town, about 485 meters high, in southern Marche. The apartment is the first floor of an empty stand-alone house, built in the 1970's. It is about 80 - 90 mq. It only has an outdoor gas bombola or a fireplace for heat.
The owner's son had stayed there during winter some years back and stated that the prices to heat seemed "normal" and that the apartment stayed at a comfortable temperature. The entire house has been empty for some time.
Does anyone have a rough idea of what it would cost to heat per month, assuming an average temperature of 65 degrees? Also, do most houses use electricity to heat the water? We haven't asked about that.
