Frequently asked questions about the hot tub
Here we have answered some product-specific questions about the hot tub.
How thick is the stainless steel in the "cup" hot tub?
The basin of the hot tub is made of 2-4 mm thick V4A stainless steel. As this basin was pressed from a plate, the stainless steel wall is thicker at the bottom than at the top and therefore has no welds.
On which surface can I place the hot tub?
The location must be horizontal and capable of bearing 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 hot tub does not stand at an angle and does not sink in when full. The outdoor heater must be at the same height as the hot tub. There should be a space of about one meter around the heater. We recommend a stable base measuring 3.10 x 2.6 m.
How does the outdoor oven work?
The outdoor heater has a double wall between which the water is located, which is heated by the fire in the heater. The hot tub and the heater are connected to each other via two hoses. Cold water is drawn into the heater via the lower hose and heated there. The warm water rises and automatically flows back into the hot tub via the upper hose.
What happens to the water after bathing?
We recommend changing the bath water – as with bathing in the bathtub – after each bath. Feuerwasser has deliberately decided against using water treatment systems that require chlorine and electricity. The wastewater can be used very well for watering and watering in the garden.
How does the cleaning of firewater products work?
The Feuerwasser products are easy to maintain: clean the inner tub with soapy water (with a soft cloth or sponge, please do not use scratching sponges, steel wool or aggressive abrasives), empty the ashes from the stove regularly and glaze the wood as needed.
Depending on the humidity and sunlight, the wood will change, so some screws may become loose, you can easily tighten them yourself.
We recommend protecting the products with the respective tarpaulin .
