RDspaguy Posted November 22, 2020 Report Share Posted November 22, 2020 In a stock tank or a spa? I have seen them in decorative ponds. Not sure I would count on it to save the pipes if the spa isn't running, and it's not about to heat it up to useable temps. 500w at 120v pulls 4 amps. It is less than 1/10th of a spa heater at 240v, and 1/3 of one at 120v. 1 Quote Link to comment Share on other sites More sharing options...
