I will be away from house this winter, and have a 'a guy' check house from time to time.
Question.....
Do I really need to drain hot water heater, I haven't int the past and everything has been fine. HW heater is in basement.
FYI, I leave my heat on at 52 degrees, and have a temperature sensor alarm, which lets me know if house temp drops below 50 degrees.
Thoughts ?
