Kastor Karhu 27 PK VO

The 27 is a taller heater, with a larger rock volume and more capacity to heat up a large sauna. Its 120-130 lbs of rocks give plenty of soft heat for your sauna enjoyment. There is a water tank on the side of the heater. Heat up your washing water with its integrated water tank. Choose either left or right side mount depending on your sauna space. 

“Karhu” means bear in Finnish language. The Kastor Karhu heater is the staple of wood fired sauna heaters, the traditional format that suits the most saunas. The design is absolutely beautiful, elegant, simple, and the engineering inside is cutting edge.

Karhu 27 PK is the latest in sauna wood fired heater design, conforming to the strict CE-certification requirements in burn efficiency, particle emissions and exhaust gas temperatures.

Why are wood fired heaters better than other types? Do the rocks know they are heated by fire instead of electricity? Well no, but they know a couple of things: there are typically more rocks and they are heated gently and more evenly. The steam delivered is thus more wholesome.

Ozone is the culprit also, as the very hot electrical resistors in an electrical heater cause the sauna air oxygen passing through to turn into ozone, which “tastes” stingy like you may have noticed outdoors after a lightning storm. There is no ozone created in a wood fired heater. Make sure you have a functioning ventilation in your electric sauna.

In a wood fired sauna the air also circulates in an optimal fashion, as the heater draws cooler air from the floor level for the burning and causes a more even heat inside the sauna.

Besides all this technical stuff, a wood fired heater has that smell of wood as you feed the fire, the charm of the flames, the subtle sound of a crackling fire burning.
