Balboa 3 kW heater for M7 systems with metal boxes
This 3 kW heater with an Incoloy element is compatible with the Balboa M7 control systems that use a metal box, such as the GL8000. It is equipped with insulating foam tape at each end of the heater, where it exits the control box, so that there is no metal-to-metal contact between the heater and the box. This heater also lacks the bottom fixing stud found on the standard first-generation M7 heater.
The Balboa M7 (or Millenium 7, as it was originally known) control system uses two very sensitive temperature sensors inside the barrel of the heater itself to detect the rate of water flow. This makes it much more reliable, in our experience, than competitive systems that use failure-prone moving parts instead, such as pressure switches or flow switches. M7 heaters require a minimum water flow rate of 75 litres/minute (4.5 m³/hour).
The heater is delivered with its M7 sensors.
It is very easy to replace a Balboa heater, and normally takes just 5 minutes.
We also offer the 3 kW M7 in a reconditioned version, checked by our team and in perfect working order.
Length (without connectors and gaskets): 381 mm (15")
