Awesome experience and outstanding Sauna stove! We installed ours this weekend and we love it. Thank you so much! I highly recommend this stove for anyone looking to purchase one

Best wood furnace on the market highly recommend burns a quarter of the wood as my last stove.

This is my first season with the VF100. Still getting used to it. Burn times are really good. My old furnace need to be filled every 4-6 hours. The VF100 will for go for at least 8 hours and there are still very hot coals in the furnace. That is a plus along with reduced wood usage. Glad I got the furnace.

Stop your hunt for a wood furnace here, you found the best. Amazing efficiency and ease of use. Great customer service. Every claim they make about VF-100 is accurate and then some. Northern WI, 12 hr burn times, 70-75 degrees all winter for 2,000 sqft house. Started late October, only at 7 face cord in early April. Only have to raise the computer setting if it’s consistently below 10 degrees. Never had it above a level 4 (1-10). Worth every penny.

It done a good job of heating our house, better than the gas furnace on really cold days. We have had a warm winter so its not the best year to compare. Overall it has done what they said it would do. Easy to get fire started and to keep it going with the front to back burn. The wood i have cut is to dry but still doing all right for heating. Cant wait to see how it works with the the right moisture wood.

We love our “Kuumma” wood furnace! Used less wood and heated more area. Kept even 3 season room toasty.

I am very happy with the quality and workmanship of the furnace. I find the vapor fire very easy to light and clean. The furnace burns the wood very efficiently leaving very little ash. I usually go four days or more before emptying the ash pan. I enjoy the Kumma’s consistent even heat radiating through the house .Knowing that I’m not burning any propane while the Kumma is running is comforting as well.

Purchased the Kuuma 100 in November and was told 5 week delivery, they were on the money delivered on time. We live in New Hartford Ct. the northwest corner and we love this furnace it is exactly as advertised easy to operate and long burn times.On a 20 degree day are house is at 74 degrees on the number low setting we only needed to use the med. setting when it was 0 degrees.Very happy with the purchase and customer service.

I’ve been running the Vapor Fire for the past year and I love it. We have a large sprawling home with a lot of long runs for the ductwork, but this furnace was able to push the hot air throughout the home easily. I’ve kept the interior at 70 all winter long, and have only had to use my secondary heat options a handful of times, typically when the temperature drops below 0. I’m using about the same amount of wood I did with the previous forced hot air wood furnace (maybe a little less), but I’m getting twice as much heat out of the wood. In years past I would have to run our secondary heat constantly just to keep it comfortable inside. This year, I barely turn them on. When it is 20 to 30 degrees outside, I typically load it up twice a day for a burn that lasts around 12 hours. Even when I have the furnace dial set to high it lasts around 8 hours. This is a huge benefit for those of us that have to work away from home and can’t reload multiple times a day. I have not checked the chimney for creosote buildup yet, but the few times I can actually see smoke coming out it looks to be flowing quickly and unobstructed, so I don’t expect and issues there. I won’t say set up was easy, but it wasn’t exceptionally hard either. I am not an electrician, but I do have a working knowledge of the trade and was able to do all the wiring myself. The color coded and labeled bags walk you through the wiring diagram easily. No redo’s, just carefully followed the instructions, double and triple checked, then turned everything on and everything worked as it should. The furnace itself is a beast and is extremely well made. Seems like it should last a long time. It is one of the few things I’ve purchased that actually works as described. Wish I bought it 5 years ago.

Outstanding customer service from inquiry through shipping and tech support. I am very happy with my purchase from Lamppa
