Today's project - heated water hose
Well my pirit hose was a big failure. It wouldn't heat up so it froze solid. I was hopeful for this thing - it was expensive - but i hear they have a high failure rate.
So I took a water hose I already had, and duct taped a heating wire to it, wrapped in pipe insulation and the whole thing wrapped in duct tape to keep it together. I put this inside a cheapo sewer hose to protect it from the weather.
Not pretty, but it worked fine last year.
