    Pipe water heater

    This smoke pipe water heater will allow you to warm up bathing water with the chimney heat. It is an ideal solution for off the grid saunas! The heat that would otherwise be lost through the chimney, is captured and used to heat water. The heater has a capacity of 5.81 gallons, and when mixed to bathing temperature, will give you over 14 gallons of perfect warm bathing water. It is compatible with all wood-heated Harvia stoves, except the Harvia 50 stove.

    Chimney kit

    The chimney kit is made of stainless steel and is easy to install. It is especially designed to be used with any Harvia wood burning stove (except the Harvia 50), and can withstand large changes in temperature. The kit includes a 59" long insulated stainless steel chimney, a 39 3/8" long non-insulated smoke pipe, a rain cap and necessary flanges and lead-throughs. 19 5/8" and 39 3/8" long extensions available.

    Protective heat sheaths

    These Harvia designed protective sheaths considerably shorten the minimum safety distances required, in essence making the heaters fit into smaller spaces. These sheats are designed to fit exactly into each specific heater, so the end result looks sleek and perfect. The shields are sold as a set of 3, allowing you to use only one of them, or all three (one back and two side shields). You can also buy the protective floor bedding. Made of black painted steel.

  • 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.
