The powerful external stove in detail
External
stainless steel stove
The external stove is crafted from 2 mm thick V4A stainless steel, allowing for a clean separation from the bathing area. This design provides noticeably more space in the basin and prevents direct contact with ash or embers while heating.
Optimized
heating performance
A heating output of approx. 35 kW ensures rapid heating. With the help of four integrated heat exchangers, the water is heated from 10 °C to 38 °C in 150 to 210 minutes.
Circulation
without a pump
Water circulation occurs solely through the thermosiphon principle, without the need for electrical pumps. This natural circulation makes heating completely independent of power connections and ensures trouble-free operation in any location.
Use & Hygiene
Filling
and draining
Water supply is straightforward via an external click valve. A bottom opening with a pipe allows for controlled draining of the water, while the internal tap simplifies filling and ensures temperature control during use.
Variable
system mount
The access ladder can be securely fixed in any desired position, while the bench inside serves as a comfortable step. Furthermore, optional accessories can be easily and securely screwed onto the wood-fired hot tub using the multiple integrated threads.
Non-porous
surface
The smooth surface made of non-porous V4A stainless steel effectively prevents the buildup of bacteria or biofilms. This allows for hygienic use without chemical additives and reduces cleaning efforts to simply wiping down the walls after a bath.
Mechanical
reliability
Without susceptible electronics or pump systems, the wood-fired hot tub is virtually maintenance-free. The simple draining after use eliminates the need for complex water analyses, making the system a straightforward solution for long-term outdoor use.

All necessary parts for assembly are included in the delivery. The wood-fired hot tub is ready for use immediately after assembly.

Questions about the Feuerwasser Wood-fired Hot Tub
What kind of surface can I place the Wood-fired Hot Tub on?
The location for the wood-fired hot tub must be level and able to support a load of at least 2 tons. Stable surfaces, such as stone or exposed aggregate concrete slabs, are well suited. It is important that the wood-fired hot tub is not tilted and does not sink in when filled. The external stove must fit next to the hot tub at the same level. A clearance of about one meter should be left around the stove. We recommend a stable substructure with dimensions of 3.10 x 2.6 m.
How much and what kind of wood do I need for a bath in the Wood-fired Hot Tub?
Basically, any type of wood and branches can be used, but we recommend wood that produces large flames and releases heat quickly (e.g., spruce wood). For heating, it is convenient if the logs are about 25-40 cm long. The thinner the logs are, the faster the water heats up. We recommend a log diameter of approx. 3-5 cm.
The wood-fired hot tub is delivered on a wooden pallet, which you can also chop up and use for firewood.
How much wood you need depends on the following factors: water temperature, air temperature, and the calorific value of the wood. For one heating cycle, you will need roughly enough wood to fill a 40x30x100 cm box. With one cubic meter of wood, you can heat the tub about 9 times.
How does the external stove work?
The external stove features a double wall containing the water, which is heated by the fire in the stove. The wood-fired hot tub and the stove are connected to each other via two hoses. Cold water is drawn into the stove through the lower hose and heated there. The warm water rises and automatically flows back into the hot tub through the upper hose.
