The supply lines and shut-offs to my bathroom run through an outside wall. For the time being, I have a trouble light shining on the access panel for extra heat. Eventually, I'll have a new room built off this wall, but for now, when it's below 0 and 35+ mph gusts, the light just couldn't cut it. Does anybody know of a safe heat source or any new products that can be enclosed? I'm not gonna try putting heat tape in there, I've seen that get too hot.

 

Might stack some hay up agains the wall for some more insulation, and leave the water dripping, that is what is done sometimes here in Okie land!! Heat tapes are known to cause fire and need to be used with caution. Goodluck,,Rick
