The Therma Heat heating pad # 277-000164 is thermostat-controlled, automatically turning on at 45 degrees Fahrenheit and turning off at 67 degrees Fahrenheit.

I do not recommend applying insulation over the heating pad as this could retain enough heat to prevent the pad from cycling back on as often as it should. It is fine to apply insulation to all other parts of the holding tank so that the warmed fresh water stays warm.
