Balboa 3 kW M7 heater first generation
Balboa's very popular 3 kW M7 heater is compatible with the vast majority of Balboa M7 control systems, including the GS series and, GL2000 and GL2001 (but not the GL8000). It has an Incoloy element, which is perfect for most requirements.
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).
We also offer the 3 kW M7 with a Titanium element for corrosive environments and a reconditioned version (depending on availability), checked by our team and in perfect working order. This heater is also available in a Plug N'Click version, which makes it compatible with BP series systems.
