Propane refill

We use propane for heating the water for the radiant floors as well as domestic hot water (with the same boiler). We also have a propane stove, fireplace and dryer. This means if there is a long power outage (like the ice storm in 1998 that left some people in the coutry without power for over two weeks), we can live mostly normally with heat, water, and cooking and laundry facilities, etc. (We wouldn't be able to run an electric range with a small generator.)
