Our take on the Costway 70000 BTU Pool Heater

The Costway 70000 BTU Pool Heater is an electric heat pump that both warms and cools pool water, with a stated range of 46.4°F to 104°F for heating and 46.4°F to 82.4°F for cooling. It is controlled from a panel with a child safety lock or from a phone app, and adds a 1/2/3-hour timer, auto mode and defrost mode. Costway rates it for indoor pools up to 21,419 gallons and recommends 8,916 to 16,064 gallons for outdoor pools, which is modest for a 70,000 BTU unit next to gas heaters of similar rating. It suits owners of smaller above-ground or covered pools who want scheduled, app-controlled heating without a gas line.
