Questions & answers

Sauna Heater FAQs

How do I choose the right kW sauna heater?

Heater size should be matched to the sauna room volume and the manufacturer’s sizing chart. Glass, stone, masonry, and other uninsulated surfaces can increase the effective heating load, so room dimensions alone are not always enough.

What is the difference between an electric and wood-burning sauna heater?

Electric heaters offer convenient temperature control and require the proper electrical circuit. Wood-burning heaters create a traditional fire-heated sauna experience and require compliant chimney, clearance, and fire-protection planning.

Are sauna stones included with the heater?

It depends on the heater and package. Some Martin Sauna listings include stones, while others may require stones to be purchased separately. Check the individual product page before ordering.

Do sauna heaters include controls?

Control configuration varies by heater. Some heaters have built-in controls, while others require a separate wall controller, Wi-Fi controller, power unit, or sensor package.

Can I install an electric sauna heater myself?

Electric sauna heaters commonly require a dedicated high-voltage circuit and must be installed according to the manufacturer’s instructions and local electrical code. A qualified electrician should confirm or complete the electrical installation.
