Forte Series, 9.8kW Sauna Heater Digital Control

The Harvia Forte is an always-ready electric sauna heater. It’s the perfect solution for those who want to enjoy the warmth of the sauna immediately without waiting for the sauna to heat up. Forte is the go to choice for people who want to use their sauna frequently. Forget the everyday hustle and enjoy the health benefits of your sauna. Open the heater's door and throw water on the hot stones, meaning you can immediately enjoy the versatile steam from the sauna heater.

Its modern appearance hides a heat-insulated stone space that keeps the stones hot. The soft lines and cool exterior of the heater are always safe for all sauna users. The Forte heater is always in energy-saving mode if the sauna is not in use, and you can quickly release the energy of the stone space into the sauna by throwing water on the stones. Going to a sauna could not be easier than with an always-ready heater. Many satisfied users have already proven that the sauna is most enjoyable when you can go there exactly when you want without the additional wait time.

Enjoy precise heater control that allows you to adjust the steam exactly as you like it. With the Forte's digital Xafir control, you can adjust the heater's features, manage energy usage, and control the steam. Operation is easy from the heat and moisture-resistant control panel, which can be installed inside the sauna. You can adjust the stone space temperature from energy-saving mode (Lo) to sauna mode (Hi). The safety feature automatically recognises if you have forgotten the heater's door open and turns off the heater. Forte is always safe to use.

Forte is the perfect heater for family saunas and especially for detached houses. The well-insulated shell keeps the stone space warm and the sauna temperature really low. Energy is not wasted, as Forte also acts as a radiator in this case and creates the basic heat for your sauna. It is always ready and it is safe to use.

Sauna master
Great heater

Works great in my sauna. Needs around 20 minutes after opening the gate for the sauna to be ready.

Leif Donovan
Really nice steam

Sauna is always ready and steam is soft which I like. Can’t be compared to my previous Harvia kip.
