Professional Sauna Heater
Installation
The heater is the heart of every sauna - and incorrect sizing or electrical work creates safety risks and disappointing heat. Sierra Sauna Co. professionally supplies and installs Harvia and Finnleo electric and wood-burning heaters in new custom builds and existing sauna structures across Sacramento, Placer, and El Dorado Counties.

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.
Harvia & Finnleo Heaters We Install
We size and install premium Finnish heaters matched to your cabin volume and how you like to heat - soft electric löyly or wood-fired sessions where local codes allow.
- Harvia Cilindro and KIP electric heaters
- Finnleo SaunaLogic and traditional electric models
- Wood-burning heaters where codes and property allow
- Proper sauna stone quantity and layering for löyly
New Builds and Heater Upgrades
Every Sierra Sauna Co. custom installation includes heater sizing and install as part of the full installation. We also replace or upgrade heaters in existing saunas - including electrical panel upgrades when your current service cannot support the required load.
Browse sauna heaters in our shop or request professional install with your equipment purchase.
- Heater-only replacement in an existing cabin
- Full custom build with heater sized during design
- Panel or circuit upgrades when load exceeds current service
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
