A common flow thru heater fitted to many spas and hots tubs manufactured in the far east. This is the larger 15" unit with a 3.0kW incoloy element and 2.00" split nuts (same size as Balboa Therm, Gecko etc).
This heater unit has a in built hi-limit reset switch, psi sensor and cable with a 2 pin JST style connector. This cable connects to the PCB in the hot tubs spa pack. Ensure when installing that there is adequate water flow to generate back pressure for the sensor.
