My parents have a house on Cape Cod, MA, will be left empty for the winter. They close off the rooms with no plumbing and turn the heat in the main house down to the minimum. The heat is forced hot water with auto antifreeze.
I have a few questions. Should this antifreeze be changed and how often? What are possible problems to having antifreeze in a heating system? I feel it would be better to turn off the water in the house to prevent a possible flood and risk the boiler not working if the pressure gets to low to circulate the water. There might be some broken plumbing but at least the house won't be flooded.
