It is not in vain that they say, “The bath steams, the bath heats, the bath fixes everything.” Unfortunately, for many, the meaning of this folk wisdom becomes apparent too late, when the list of illnesses begins to approach a critical point. And yet, it seems so simple, as the old folks taught: a hot bath, a birch broom, and no ailment will take hold! The preventive properties of the bath have been known for centuries, so those who care about their health constantly “befriend” it. It’s not uncommon today to have private baths and saunas in summer cottages, garden plots, and country communities. Saunas are also built in enterprises, sports complexes, complemented by relaxation rooms, pools, gymnasiums, and other attributes of health improvement.
The construction of the bath or sauna building itself will not pose a particular challenge for people who know how to handle an axe and saw, especially for readers of “Modelist-Konstruktor.” In this case, one can use “grandfather’s” methods, traditional, time-tested ways, or more modern technologies (see, for example, “M-K” No. 10 for 1991). However, every builder sooner or later faces the main question—the construction of the stove—since it is absolutely clear: without a good stove, there will be no hot bath.
In such a situation, I thought a lot about this question, flipped through a lot of literature, saw a lot in nature, and experienced a lot myself, taking the heat of these baths. Strangely enough, most designs didn’t appeal to me because the steam in them is “raw.” And yet, the most important thing in a sauna or bath is the temperature and “dry” steam.
So, how to build a stove in a bath on your own plot? Firstly, I believe that using electric heating is not economically viable. Secondly, stove designs with side water tanks do not allow obtaining steam with the necessary “dryness” since the water boils much earlier than the steam room volume heats up—creating that same “raw” steam.
After analyzing all of this, considering my capabilities, I acted as follows. I made a simple “bourgeois” stove with a heat exchanger inside the firebox for heating water and an open pocket above the firebox for stones. The placement of the “stone pocket” is dictated by safety considerations—by directing the steam upward, you can get severe burns, so in my version, it goes up.
The stove itself is made of ordinary sheet steel with a thickness of 4…5 mm. I do not recommend using “stainless steel” for such purposes due to its low thermal conductivity. However, it is the most suitable material for the tank with hot water and the heat exchanger.
The tank is made separately from the stove, so it can be placed in any room: in the anteroom, in the washing area, or even on the external side of the bath—depending on the area and the convenience of water supply. The tank is mounted on the wall, its lower level should be at least 500 mm higher than the stove’s heat exchanger. The tank and heat exchanger nipples are connected by a rubber hose with clamps. Ensure that the hose does not sag and rises evenly from the stove to the tank. In principle, the hose can be replaced with pipes, depending on your capabilities.
The overall construction of the stove and its individual parts is shown in the drawings. I just want to note that to avoid breaking the tank and heat exchanger during the winter, you need to drain the water from them (by removing one end of the hose). If the water system is assembled from pipes, it is advisable to include a tee with a plug or a special valve.
