What Are Our Customers Saying?

I have a Kuuma Vaporfire 100. It has kept my home very warm over the past 4 years I’ve had it installed. Not only that, my chimney has never needed swept! Because there is absolutely nothing in it! I burn way less wood. Never have to worry about safety hazards as it’s built like a tank. No chimney or creasote fires. Can’t say enough good things about these furnaces and the folks that make them! Daryl Lamppa is great with customer service and answered any and all of my questions immediately! Thanks again guys!

I bought a Kuuma Sauna Stove about 15 years ago. It still looks and heats like new. Good people, good stoves, local business – win, win, win. Bill Hansen

The guys working there had pride of craftsmanship. They should. They build a great product! Tom Crafton

The stove is fantastic and easily heats the sauna to 180f or higher if I want. These are great stoves and highly recommend them. Paul Geyen

Going into my 3rd winter with our Vapor Fire 100 furnace and we could not be happier. Bill Widmer

The heat is strong and consistent. It holds a lot of stones and makes wonderful löyly. Jeff Pyzyk

I’ve had a Kuuma electric sauna stove for about 20 years and still works excellent… I recently bought a cabin with Kuuma wood sauna stove and I love that stove also they are in a class of their own… Nathaniel Dostert

We purchased our furnace last fall. It is the best furnace we ever owned. Cindy Torma

We bought the electric floor model, there have only been 3-5 days we haven’t used it in the last two years. Industrial grade stainless steel construction, protected elements, we expect many more years of saunas before we need to change out the elements. Mike Hill

This furnace is absolutely fantastic! I am a first-time wood burner, and the only learning curve involved was learning how much wood to load when it got a bit warmer so you don’t overheat the house. Paul Junion

The heat and steam are perfections and we are so happy we found the very best for our cabin sauna! Thanks for wonderful craftsmanship! Susan Odden
