Balboa BP Series 4.0kW 230V Flow Thru Heater G7412

Balboa BP Series 4.0kW 230V Flow Thru Heater G7412

The Balboa G7412 M7 Heater Assembly  is a 4.0 kW stainless steel flo-thru spa heater designed as an OEM replacement for Balboa BP and VS/EL series control systems. It combines durable construction with M7 dual-sensor technology for reliable temperature control and easy installation in 2" plumbing.

Product Overview

• Model/Part Numbers: G7412, 58303 (commonly associated with Balboa M7 4.0 kW heater assemblies such as 58104/58148).
  
• Heater Type: 4.0 kW flo-thru heater with Incoloy element in a stainless steel housing.
  
• Dimensions: 2" plumbing connections, approximately 15" overall heater length.
  
• Voltage: Rated 230V, designed to operate on 120V or 240V systems depending on control box wiring.
  
• Sensors: Integrated Balboa OEM M7 dual temperature/flow sensors mounted in the heater tube.
  

Key Features

• Stainless steel heater housing for excellent corrosion resistance and long service life in hot, chemically treated spa water.
  
• 4 kW Incoloy flo-thru element provides efficient, even heating while resisting scaling and pitting better than standard elements.
  
• Balboa M7 dual-sensor technology uses two identical sensors to monitor temperature and flow, eliminating the need for a separate pressure switch.
  
• Includes hardware: typically supplied with 2 heater split nuts, gaskets, and plastic tailpieces to connect to 2" plumbing, plus the two pre-installed M7 sensors.
  
• Plug-and-click heater cable (such as Balboa 25263 for BP systems) is available separately for quick connection to compatible control boards.
  

System Compatibility

• Commonly used on Balboa BP Series control systems, including BP501G1, BP501G3, BP2000G1, and BP7 spa packs.
  
• Now also found on several Balboa VS and EL Series systems, such as VS501Z, VS510SZ, VS520SZ, and EL2001M3, where a 2" x 15", 4 kW M7 heater is specified.
  
• Designed as a drop-in replacement for many OEM-installed Balboa M7 flo-thru heaters in modern hot tubs using 2" plumbing.
  

Benefits

• Reliable spa heating with fast recovery and consistent temperature control thanks to the 4.0 kW output and M7 sensing.
  
• Simplified installation and service since the sensors are already mounted in the tube and the assembly is built as a direct-fit replacement for M7-equipped packs.
  
• Enhanced safety and diagnostics from M7 technology, which can detect flow restrictions and overheat conditions without external pressure switches.
  
• OEM quality assurance from Balboa Water Group, a leading manufacturer of spa controls and heaters, helping ensure compatibility and durability.
  

This Balboa G7412 / 58303 M7 4 kW heater assembly is an ideal choice when replacing a failed M7 flo-thru heater on BP, VS, or EL series systems that use a 2" x 15" stainless tube and dual M7
