Types of sauna heaters

Electric sauna heaters 

Electric heaters work by transferring heat from heating elements onto heating stones that radiate heat throughout the sauna. Electric sauna heaters typically take 30-60 minutes to heat up the sauna, and the size of the heater needed depends on the size of the sauna room - from 3.5kw for a 124 ft³ sauna all the way to a 18kW for up to 1230 ft³ saunas.

The cost of electric sauna heaters varies, with the cheapest starting at around $1,033 with prices going up to $5,875.00 for more high-end and technologically advanced models. Electric heaters require a dedicated electrical circuit and proper ventilation and should be installed by an electrician. A single sauna session can cost you around $1.44 assuming a $0.16 per kwh cost and a 6kw heater. 

Infrared sauna heater

Infrared sauna heaters use infrared panels to directly heat the body, rather than the air. They can heat up in just 10-20 minutes and are more energy-efficient than traditional electric heaters. Infrared saunas come built in with infrared heaters however if you need replacements or extra heaters you can get them in individual 400w panels. Prices for infrared panels range from $200 to $500 or more. Installation is relatively simple, as they can be plugged into a standard outlet and do not require special ventilation.

Gas sauna heater

Gas sauna heaters, which run on either natural gas or propane, heat up quickly, usually within 30 minutes. The size of the gas heater should be based on the sauna room's cubic footage. Gas heaters are one of the most expensive options on the market with prices starting at around $3,600, mainly due to the fact their a niche product. Installation requires a gas line and proper ventilation, and it is recommended to have a professional handle the installation. 

Wood-burning sauna heaters

Wood-burning sauna heaters provide a traditional sauna experience and can heat the sauna in about 30-60 minutes, depending on the size of the heater and sauna room - from 12kw for a 212 ft³ sauna all the way to a 21kW for up to 848 ft³ saunas. Wood-burning heaters are often the most affordable option, with prices starting at around $999 up to $3,798. However, they require a chimney or flue for proper ventilation and a steady supply of firewood. Installation should be done by a professional to ensure safety and proper functioning. Operating costs are minimal, as firewood is relatively inexpensive.

Wood burning vs electric sauna heater

Wood-burning and electric sauna heaters offer distinct experiences. Wood-burning heaters provide a traditional, rustic ambiance and the aroma of burning wood. There's nothing quite as enjoyable as watching the fire crackle as you sweat. However, this comes at a time cost - you will need to spend longer preparing the heater and do take longer to heat up. Electric heaters on the other hand offer convenience, precise temperature control, and faster heating times. 

Wood-burning heaters are ideal for outdoor saunas (although you can use electric too), while electric heaters are suitable for indoor saunas. Wood burning sauna heaters may be too large for your sauna if it's smaller than 212 ft³. The choice between the two depends on personal preference, available space, and desired sauna experience. Also consider how readily available sauna firewood is, in your area. Electric saunas will need an electrician to install, so bear this in mind. Ultimately, both types can provide a relaxing and enjoyable sauna experience, and the decision comes down to individual preferences and practical considerations.
