Electric Sauna Heaters

What size electric heater do I need?

This is the most critical step to get right. The power you need (measured in kW) is based on your sauna's volume. A heater that's too small will struggle to heat the room, while one that's too large is inefficient. To get a precise recommendation, our Sauna Heater Size Calculator is your best friend.

What are my options for controlling the heater?

You have great options for any style. Many heaters come with simple, reliable built-in controls. For a sleeker look and more features, you can upgrade to a wall-mounted digital panel. For the ultimate in convenience, explore our WiFi-enabled sauna controls that allow you to preheat your sauna from your phone.

What are the electrical requirements?

This is a crucial planning step. Nearly all electric sauna heaters require a dedicated 240V circuit, which must be installed by a qualified and licensed electrician.
