The Balboa Auxiliary Slave heater is designed to give an extra 3kw of heat when heating larger or commercial hot tubs where heating speed is essential.
The system is connected to the existing internal PCB as per image and when working in tandem will create the extra 3kw of heat to double heating time.
The boost to heater would of course be an invaluable advantage to owners of commercial spas in holiday lets when the water needs to reach temperature as fast as possible between the guests.
The Balboa slave heater enables this and can be installed as a retro fit on existing hot tub as long as they already have the Balboa BP or GS systems.
The Balboa Auxiliary Slave heater is now in stock and can be found on the below link.
