Heating wood-fired hot tub

Before you start lighting the stove, it is very important that your Hot Tub for 95% is filled with water. The aluminum stove is exclusively built to work under water.

Lighting a hot tub heater

Using a few firelighters available at any supermarket, you can light the stove. Then lightly fill the stove with some kindling (spruce boards, pallet wood) and a little cardboard. Make sure that the stove is getting enough air. Once the stove is burning well, place the stove lid on the stove opening so that it gets the best possible draft and loses the least amount of heat.

To promote the draft, it sometimes helps to blow air into the narrow air opening (with an internal heater). Fill the stove with some regularity and prevent too much wood from getting stuck in the stove.

Stoking hot tub heater

During the heating up you will notice that the obtained heat appears on the surface especially at the top of the Hot Tub. This will sometimes cause nice fumes. However, when heating up, we recommend that you mix the water frequently with a paddle. Also use the lid to retain the heat obtained as much as possible. Too much heat loss and waiting time is thus avoided.

What customers say

R. van der Jagt

Our new hot tub has been in place for a few months now and we are very satisfied. This started with delivery and installation. With us he had to go over the roof. This was not a problem, because the hot tub was delivered neatly packaged on a pallet. Once on the ground it was just a matter of removing the foil and tilting it and it was standing. Installing the heater and filter was also a matter of attaching hoses, turning and firing. We have already spent wonderful hours in it. Both in the hot summer and now in the cold under the starry sky.

Bas and Agnes

I would like to thank you very much for thinking along and delivering the hot tub. The finish and appearance in our garden is more than expected! For now, the neighbors can watch (later we'll blind this corner), but everyone is jealous! Since the delivery last Saturday there hasn't been a day that we haven't enjoyed the tub. Especially with this warm weather, daily heating is not necessary, which results in a refreshing bath every day. We are therefore very pleased that we were able to submit all our questions and wishes to Isbjørn and Woodmex before purchasing this eye-catcher.


Very satisfied with our Isbjorn hot tub. The large heater heats the tub quickly. In the beginning, be careful not to heat too hard so that it gets too hot. All in all, it is wonderful to enjoy and also super cozy with the whole family. Well advised and nice to see the manufacture.

Finally started installing the hot tub today. We couldn't wait to sit in it for a while. And thanks for the warm hats.
