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 just 90 to 120 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.

Every stainless steel hot tub is a handcrafted unique piece. In a specialized workshop, a 4 mm thick, food-grade V4A stainless steel plate is precisely pressed into the hemisphere shape. The resulting gentle grooves in the metal are the authentic hallmark of this special manufacturing technique. Complemented by the handcrafted external stove and the access ladder, the result is a perfectly coordinated overall package.

The stainless steel hot tub arrives ready for use to you — simply place it in your desired location, connect the external stove via two connecting hoses, secure the access ladder in place, and attach the flue pipe. Connect the water using the click valve and that’s it.

Operation is incredibly simple — you can find all the details in the PDF.

Questions about the Feuerwasser Stainless Steel Hot Tub

How thick is the stainless steel of the hot tub?

The basin of the stainless steel hot tub is made of 2-4 mm thick V4A stainless steel. Since this basin is pressed from a single sheet, the stainless steel wall is thicker at the bottom than at the top and has no seams.

The location must be level and able to support a load of at least 1.2 tons. Stable surfaces, such as stone or exposed aggregate concrete slabs, are well suited. It is important that the stainless steel 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.

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 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 30x30x100 cm box. With one cubic meter of wood, you can heat the tub about 11 times.

The external stove features a double wall containing the water, which is heated by the fire in the stove. The stainless steel 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 stainless steel hot tub through the upper hose.
