Ok me and fiancee have a 2 family home. There are two bedrooms down stairs and the apt is approx 1,000 sq ft. and their bill has been about 190-$200 a month. This is the gas bill for heat and hot water. We live on Long Island, New York. I know it has been rally cold but it seems high. They keep their heat on 69 during the night and shut if off during the day. I check the hot water heat and it is set at 120 degrees. Is this normal?

Thank you very very much for any input.
