Maybe the following experience might help others: to ensure that your under home pipes don't freeze when the temp is in single digits or below, I did the following to our Clayton Richfield modular--first, the concrete block perimeter foundation provided fairly good protection from strong cold winds, however the automatic vents needed some adjustment to make a tighter fit. Second, the fresh water inlet pipe was wrapped with heat tape and insulation and plugged into an outlet that we had added under the house. Third, a 60 watt lamp bulb was mounted near where the line entered the floor but away from any flamable materials (note: we had to add the elect. outlet as it is not required in a state coded modular). Fourth, a remote temperature sensor was placed near the pipe entry so we can read the under-house temperature from our laundry room. The under house temp has never gone under 39 degrees (usually in the 40s) when the outside temp is in single digits. The light bulb seems to make a difference of about 2 or 3
degrees warmer. The most important: a tight perimeter - thin skirting would probably not work. Probably very important, the heat tape and wrapped pipe. So far, no freeze ups. The heat pump is working like a dream. bjackm |
