Greetings We are renovating a 48k (our estimate) pool with large hot tub (9’ across - inner measurement). There is no way we could afford to heat the pool in the winter, so we are looking to just heat the hot tub. Any recommendations on an electric heater for a saltwater system? The wholesaler where we are getting our equipment and tile/coping suggested we contact Coates Heaters and order direct from them. Any thoughts?
