Why Professional Sauna Heater Installation Matters

Sauna heaters require precise sizing for cubic volume, proper stone loading, dedicated electrical circuits, and code-compliant clearances. A heater that is too small never reaches proper löyly; one that is too large wastes energy and stresses your electrical panel.

Our licensed team handles heater selection, supply, electrical install, stone layout, and final safety inspection - whether you are completing a new custom build or upgrading an existing sauna.

Our Process

How Heater Installation Works

Heater work is short compared with a full cabin build, but the electrical and stone details still need to be done correctly. We confirm volume, clearances, and panel capacity before we order or move equipment.

Measure cabin volume and review existing wiring and clearances
Recommend Harvia or Finnleo model and stone load
Install heater, dedicated circuit or GFCI protection as required
Layer stones correctly and run a controlled first heat
Walk you through controls, heat-up time, and care
