An Electric Heat Pump would be a great choice to heat an 18'X33' oval swimming pool. Heat pumps will operate more efficiently than a natural gas or propane heater reducing your swimming pool heating costs. Any model 84,000 BTU or larger would be sufficient for an 18'X33' oval swimming pool. If you would like to extend your swimming season into the late Fall or early Spring or if you live in a colder area we would recommend oversizing the heat pump to a 112,000 BTU or larger unit.

Pool heaters must be installed in accordance with all local and state codes and you must follow the manufacturer's installation instructions and procedures.
