Yep, I bought and installed something like that in our pump house after the big freeze 2 years ago. The pumphouse was the only place that we had a pipe freeze. It was on the opposite side from the work light, and I assume due to the power outages that we had. Fortunately, it was an easy fix so I didn't have to wait for a plumber like so many people.
