Balboa Heaters With Sensor & Pressure Switch

Welcome to the Balboa heaters with sensor and pressure switch section of our store.


These types of heaters are very rare but can be found in older American & Canadian manufactured hot tubs and spas here in the UK. This method of using a sensor and pressure switches to prevent the heater being dry fired has now been replaced with the new M7 sensor technology which uses two sensors one at each end of the heater tube.

Find below all the heaters manufactured by Balboa with a pressure switch and sensor, Balboa part numbers will be writen on the heater tube and to match the correct replacement you need to use the first 5 numbers like 58046 etc.
