  • Harvia Always Ready electric sauna heater, 4, 6 and 9 Kilowatt options 

    Enjoy sauna whenever you want

    This Harvia heater lets you enjoy relaxation on demand. The Forte heater is always at your service - no pre-heating required! When not in use, the heater goes into a low power mode, while still keeping the rocks hot enough that you can just flip the lid open and start enjoying the sauna!

    • No pre-heating required - just lift the lid and your sauna is ready
    • Perfect for installation as an embedded heater
    • ECO mode saves electricity by enabling very low heat setting without turning off
    • Digital splash-proof touch pad control can be wall mounted inside or outside the sauna room
    • Family safety:
      • turns off if you forget to close the lid
      • keypad lock in controls

    Dual use steam sauna

    You can use the Forte heater both as a hot traditional sauna heater, or for lower temperature steam bathing. You get the traditional experience if you turn the heater power on full (from stand-by ECO mode), and open the air circulation valve fully. If you leave the air valve closed, the sauna doesn't get so hot, and you still get nice amount of silky smooth steam by throwing water to the stones. This heater lets you choose between traditional Finnish style sauna and a Turkish steam bath!

    Harvia Forte is a combined steam and traditional sauna heater

    Steam or traditional sauna? Have it both ways!

    Receiving your heater delivery:

    When the shipment is on its way, the shipping company will call you to set up the delivery time.

    When receiving any freight shipment such as a heater, there are two important things to check:

    1. That you have the right number of boxes, and
    2. That there is no shipping damage.

    Please check the delivery receipt / bill of lading. It will show how many crates, boxes or other items there should be total. Make sure the numbers match with what you're getting.

    If there are shipping damages:

    With freight shipments there are generally two types of damage that can occur:

    • visible damage (damaged container/crate)

    If there are any damages or item shortages, make a note of these on the delivery receipt. It is important to be specific, so later insurance claims can be processed quickly and easily. It is also recommended to take pictures of the damage if you can. Visible damage needs to be reported on the delivery receipt, and concealed damages within 72 hours.

  • About Us

    World class sauna design expertise

    Our Values

    Customer first: When running a business, there are always a lot of decisions to make, and a lot of the factors affecting those decisions often seem to be opposing each other. We find that these decisions get easier when we ask a simple question: what would the customer want?

    Honesty & Integrity: Finns are very honest people, sometimes to a fault (life would be easier if we didn't find even white lies difficult!). Integrity is an extension of honesty over long period of time. We think twice before promising something, because we don't go back on our word.

    Commitment to quality: For us, quality means doing things right. In order to stick to our long term goal of advancing the Finnish/Nordic sauna culture in the US, we can't make big compromises for small short term savings. We accept the fact that quality has its price, and are ready to look farther into the future. That goes for both customer service and the quality of the products.

    Vision & Mission

    Our Vision is simple: we believe that the people in United States would have better lives with more saunas. Our Mission is to further that goal by offering you the right products and a great long term customer experience.
