The Balboa M7 heater is a highly sought-after component for all GS and GL series control systems. Although this version is no longer manufactured by Balboa—who now exclusively produces the second-generation heater with Plug N'Click receptacles for BP series systems—this 100% compatible equivalent is expertly crafted.
Constructed with an Incoloy resistor, made from a nickel-iron-chromium alloy, it offers excellent resistance to oxidation and corrosion, making it suitable for a wide range of applications.
What sets the M7 system apart is its unique water flow monitoring, utilising two temperature probes (included) located within the heater itself. This innovative approach provides a far more reliable solution than conventional pressure switches and flow sensors. The M7 heater requires a minimum water flow rate of 75 litres per minute (4.5 m³/hour) for optimal performance.
We also offer a 3 kW M7 variant with a Titanium resistance and a refurbished option (subject to availability) that has been inspected and certified to be in perfect working condition by our team.
The heater comes complete with two clamping rings and gaskets. Be sure to order connectors for 2-inch pipes, the standard size, as well as 1.5-inch connectors, if needed.
