The Balboa GS100 M7 2.0kW Spa Heater is designed specifically for use with Balboa GS100 plastic control boxes, delivering reliable and efficient temperature control for hot tubs and spa systems.
Featuring advanced 24” M7 dual-sensor technology, this heater accurately monitors both water flow and temperature directly within the heater tube. The two integrated M7 probes communicate with the control pack’s onboard software to regulate spa performance, automatically adapting to flow direction and detecting restrictions such as blocked or dirty filters.
Supplied with an AMP plug connection, this heater connects directly to compatible GS100 control systems for straightforward installation.
Constructed with a durable Incoloy heating element, it provides excellent corrosion resistance and long service life in demanding spa environments.

-
Eliminates moving mechanical parts
-
Automatically adapts to flow direction
-
Detects restrictions and dirty filters
-
Improves reliability and reduces fault codes
