Gecko In.Therm Heater, 4 kW

The Gecko In.Therm heater is a complete heater assembly with a built in temperature sensor and water flow detection that eliminates the need of a pressure switch.

Includes installed cords that plug in to your spa pack.

Red & blue colored models are the same (now being made in red). Also known as part number: 0603-409001.

The unique seamless enclosure and its cover gasket eliminates all risks of water infiltration. Filled with epoxy, its electronic board compartment is protected against the stress of water flow vibrations.

The Gecko In.Therm heater can command multiple power levels on its single element and will heat on full power only when necessary, thus reducing the demand on the heater element.
