HW heater and freezing.
Considering the hw heater is enclosed and probably insulated, how cold must it be for the heater to be damaged due to freezing?

There is NO correct answer to your question. I tell my customers that IF it is below 32 degrees, then there may be freezing. It actually has to be colder, but there is no way to accurately state the range of freezing that may cause damage. IMO, if it is 30 degrees for 1 month, then the odds are the W/H will freeze. Doug
