Balboa GS100 Hot Tub Heater Kit

Balboa GS100 Heater Kit.

2kw Element for low voltage included.

If you are making, upgrading or repairing a hot tub / spa (Just hot bubbles) and require a simple but effective heating system with a control panel that shows the temperature then this kit is for you.

It includes all the parts and glues required to build and connect the pluming along with a basic diagram that shows you where it all roughly fits.

This kit is also great if you're thinking of adding water jets or a 2 speed pump later because the control panel / control system can also accommodate these.

Fitting Description
  • 2 x inlets that should be 24" away from each other and 6" above the base of the hot tub
  • Gate valves
  • waterway Filter canister - C4950 paper filter included
  • Gate valve
  • Pump
  • GS100 control system
  • Gate Valve

The bundle is all plumbed with 1.5" pipe ID (Internal Diameter) and can easily be modified to direct the water through 6 jets in the side wall of the wooden hot tub.

Fitting instructions is included on each of the product pages, for example the heater will require the pressure switch to be brought inline so it cannot switch on when the pump is not running.

This kit requires 2 x electrical plugs to complete, wires are included with both the pump and the heater unit.

The heater unit  is 2kw 8 amps and the pump is 3.8 amps.

A filter cartridge is provided inside the filter canister.
