planning to go away for 6 weeks during the winter. Was told that I could shut off my main water line to the house and still keep the heat on (52 degrees). Have a force hot water base board heat. Is this true and what are some of the problems that could occur ? Thanks.

Apparently you live in an area where the temperature can drop to or below freezing.

By leaving the heat on, it will help to prevent the water in the house pipes from freezing. If they freeze, the water will expand and burst a line, faucet, joint, etc.

Same condition could happen to the toilet tank or bowl water. Water in the drain elbows or the lines in the laundry room.

I'm not sure if the heater you have must have a constant pressurized supply of water while in service, to refill, if needed. It most likely is a closed system. Best to confirm that before closing off the water main.

Good Luck,
