Sauna Heater & Electrical

All electrical wiring must be performed by a qualified and licensed electrician with complete knowledge of local codes and regulations. Costs of hiring an electrician can vary greatly depending on several factors such as your sauna’s distance from your electrical service box, the state you live in, and the cost of materials. We recommend you get quotes from 2 to 3 different licensed electricians before you begin the installation.

The sauna heater requires 220v and must be hard-wired to the electrical box. If your sauna comes with a 6kW heater, it will require a 30-amp breaker and 10/2 wire, unless it is positioned more than 30 feet from the breaker in which case it will require 8/2 wire. If your sauna comes with an 8kW heater, it will require a 40-amp breaker and 8/2 wire. Finally, if your sauna comes with an 9kW heater, it will require a 45-amp breaker and 8/2 wire.

Your electrician will drill a hole in the wall of the sauna below the heater for the conduit. All of the wires will come into the sauna through this hole. In a barrel sauna, it can also come up through the floor below the heater.

Use copper wire with 90C insulation. Do not use aluminum wire to make the connection. Consult with an electrician so you can determine the requirements for your particular situation. All wiring must conform to all national, state, and local codes and regulations.

Because our heaters run on 220v and draw less than 40 amps they are quite energy efficient and should not be a significant drain on your electricity bill.

The light will require 110V power and an on/off switch must be wired inline.

All our heaters are made in Finland by Harvia, the world's number 1 heater manufacturer.

Harvia is the gold standard for sauna heaters and we import heaters directly from Europe to use in our saunas.

Our heaters (with the exception of our wood-fired heaters) are hardwired. They must be directly connected to a power source by a qualified and trained electrician.

On certain models, we offer heater power upgrades. A higher power heater will heat up the sauna faster.

For example, on our panorama saunas, you can upgrade from a 6kW heater to a 9kW heater.

Any available heater upgrade options will be shown on the product page.
