Thanks, mine is a 1000 watt and I'll experiment leaving it plugged in for a month when it's cold. We've been in the 30's to 50's (F) for highs lately and not concerned with starting at those temps. Mid to upper 20's overnight. If it cycles off at the water temp you mentioned I can live with that. The building is uninsulated, but I suppose throwing maybe a concrete "blanket" over it and tucking it in would not hurt things and maybe save a little power usage.
