Balboa VS100 M7 Hot Tub Heater 4.0kW 240V / 1.0kW 120V – G7414 / 58203

The Balboa VS100 G7414 Hot Tub Heater Assembly is a genuine Balboa replacement flow-through heater designed for compatible Balboa VS100 and GS100 spa control systems. Featuring a compact 10" stainless steel heater tube, dual M7 sensors and a 1-1/2" plumbing connection, it is an ideal replacement when your original VS100 heater has failed, developed a leak or is no longer heating properly.

Operating at 4.0kW on 240V or 1.0kW on 120V, this heater is designed for Balboa systems that use the compact VS100 heater configuration. The stainless steel housing contains an Incoloy flow-through heating element for dependable spa and hot tub heating.

Balboa's M7 technology uses two temperature sensors mounted in the heater assembly to monitor water temperature and conditions within the heater. This eliminates the traditional pressure-switch configuration found on many older spa heating systems.

The assembly includes two Balboa M7 sensors with approximately 36" cables, a 34" AMP-style heater power cord, and two 1-1/2" split union nuts, providing the primary components needed when replacing a compatible VS100 heater.

This heater replaces several common Balboa and Hydro-Quip numbers, including 58198, 58203, 58205, 26-0020A, 26-58198-K and 26-58203-K. Always compare the part number, heater dimensions, plumbing size, voltage and electrical connections with your existing heater before ordering.
