Hot tub with a wood stove
What an internal stove means in practice
The stove is set into the shell itself and takes up part of the space inside. Water circulates around it by itself, without a pump – warm rises, cold sinks.
What follows from that:
- You need no electricity. The tub can stand anywhere on the property, even where there is no supply.
- Heating in 1.5 to 2 hours from 10 to 37 °C. Light it in the afternoon, bathe in the evening.
- You can see the fire through the heat-resistant glass in the door – that is half the experience.
- It costs you space. In a tub for six, the stove takes roughly the room of one seat.
The chimney is protected by a stainless steel mesh, so you cannot burn yourself on it by accident. If you want maximum space inside, look at hot tubs with an external stove.

How much wood it takes
For the first heat-up of a cold tub, count on two or three armfuls of hardwood, so roughly 15 to 20 kg. To hold the temperature while you bathe, add wood about once an hour.
Softwood burns faster, gives less heat and tars up the flue. Use birch, oak or beech.
If lighting a fire by hand does not appeal, there is the ELECTRIC range with a 3 kW heater instead of a stove. The comparison is in Wood stove or electric heating.
Frequently asked questions
Can a tub with a stove stand on a wooden deck?
Yes, if the deck carries the load and there is a non-combustible base under the stove. The stove radiates heat downwards and sideways – timber boards directly beneath it are a risk. We solve it with a metal sheet or paving under the whole tub.
How long does the water stay warm?
With the thermal cover on, the temperature drops by roughly 5 to 8 °C overnight depending on the outside temperature. In the morning a short top-up is enough rather than heating from scratch.
Can the stove be fired without water?
No, never. The stove is cooled by the water flowing through it. Firing it dry destroys it and is the most common warranty claim that is not covered.
