What we do
Work we take care of
Heater supply circuits
A dedicated circuit run to the heater or control unit, sized to its rated load.
Control and sensor wiring
Wiring between the heater, controller and sensors as set out in the installation instructions.
Isolation and switching
An accessible isolator outside the sauna cabin so the heater can be switched off safely.
Switchboard capacity
Checking spare capacity and protection at the board before the circuit is added.
Outdoor and barrel saunas
Weather-protected supply and cable routes for saunas installed outside.
Testing and certification
Circuit tested at completion with a Certificate of Testing and Compliance supplied.
Getting the circuit right the first time
Sauna heaters draw a steady, high load and often need a specific supply arrangement — single or three phase, a set cable size, and control wiring that runs separately to the power supply. The heater's documentation drives all of it.
The cheapest time to run the circuit is before the cabin is lined or the deck is finished, so it is worth talking to us early. Send through the heater model with your enquiry and we can quote the circuit accurately.
- Heater model and rated load confirmed before quoting
- Circuit and protection sized to the manufacturer's requirements
- Isolation located outside the cabin
- Cable routes kept clear of heat and moisture
