What are the best electric heater options for a 900 gallon spa? I’m in Philadelphia so I think a heat pump wouldn’t be very efficient. We would like to use the spa year round.
We’d recommend the 11kW Raypak E3T heater for your 900 gallon spa. This heater would raise the temperature of your water 5° an hour. It will perform more efficiently if you keep your spa covered. Click Here to View More Details of the Raypak 11Kw Electric Heater
