Balboa Heaters With M7 Sensors

Welcome to the Balboa M7 heaters section of our store.

The M7 heaters from Balboa are very distinctive due to having two sensors mounted to the heater tube, one at each end. These heaters are used on Balboa M7, BP, GL, and GS series spa control packs with slight variations between them.

Heaters for the Plastic BP, GS & GL series control boxes have a stud on the top and bottom of the heater to attach to the inside of the box. Heaters for Metal boxes M7's and GL's are strapped inside the control box and do not have the extra studs on the heater tube, they are also recognized by having black felt like tape positioned at each end of the tube to prevent vibration noise against the metal control boxes.
