Sauna heaters sized to the room and wired safely
A sauna heater has to match the room it sits in. Too small and the room never reaches temperature; too large and it short-cycles and wastes power. We size electric heaters against room volume, insulation and any glass or stone surfaces, then choose wall-mounted or floor-standing units with built-in or external controls.
Installation covers the details that decide safety and lifespan: heat-resistant cabling inside the hot room, the correct supply and isolator, temperature sensor placement, manufacturer clearances to benches and walls, a heater guard and correctly stacked sauna stones. We also replace failed or undersized heaters in existing saunas, including rooms built by others.
How we work
- Room survey: volume, insulation, glass and power
- Heater sizing and model selection
- Electrical planning: single or three-phase, isolator
- Mounting with clearances and heater guard
- Sensor and controls placement, stone loading
- Heat-up test, cut-out check and handover

Common questions
What size sauna heater do I need?
As a rule of thumb, allow about 1 kW for every 1–1.5 cubic metres of well-insulated room, adding capacity for glass walls, stone surfaces or weaker insulation. Many home saunas fall in the 4.5–9 kW range; we size the heater after measuring the room.
Does a sauna heater need three-phase power?
Smaller heaters can often run on a single-phase supply with a dedicated circuit; larger heaters are usually wired three-phase. The right choice depends on heater output and your existing supply capacity, which we check during the survey.
What does sauna heater installation cost?
It depends on heater output, the control type, whether new heat-rated cabling or a supply upgrade is needed, and whether an old heater has to be removed. We quote after a free site survey of the room and power supply.
How often do sauna stones need replacing?
Stones break down with repeated heating. Restack them and remove crumbled pieces at least once a year on home use, and more often in busy commercial saunas, because packed or broken stones restrict airflow around the elements.
