Kastor sauna stoves - environmentally friendly and economical
Founded in 1910, the Finnish company Castor has to date produced more than two million sauna stoves. Wood-burning and electric stoves for Kastor baths are actively used in both private and public saunas and baths as an effective, economical and safe source of heat.
The Kastor metal body is highly durable, allowing the stove to be used effectively for many years. Of particular note is the high efficiency of Castor stoves: the designs of this manufacturer have the effect of complete combustion of fuel, which makes them not only very economical, but also perfect from the point of view of concern for environmental cleanliness. How profitable Kastor models are in practice can be judged, for example, by the fact that in order to heat a small steam room to 100 degrees, only seven or eight 40-centimeter logs are required. Another important advantage of the attractive, inexpensive and easy-to-use Kastor sauna stoves is the patented Coanda air exchange system. This system ensures economical fuel consumption and long-term heat retention even after the coals have completely burned out.

Kastor - sauna stoves of excellent quality, versatility and reliability of equipment for baths and saunas... For those who truly understand the nuances of the sauna business, these words have long become synonymous!
Design features of the Kastor stove
These are sauna stoves with soapstone lining. The body of the thermal unit is made of high-strength steel up to 8 mm thick, and a 5 mm stone lining protects steamers from accidental burns and harsh radiation. Kastor products are reliable, environmentally friendly and economical. As for the service life, you can be sure that you will not have to ever think about replacing this stove. If this problem appears, it will be in your children, or even grandchildren.
The excellent characteristics of the stove are due not only to the quality of the materials used to manufacture the units, but also to a fundamentally new design that ensures the CONDA effect - complete combustion of fuel. The efficiency is 70%, that is, by laying 4-5 logs of 8-10 cm in diameter, you ensure a temperature in the steam room of up to 100 degrees, if, of course, you have correctly selected the stove model for the volume of the heated room.
Soapstone cladding is much less “capricious” than brick: it does not require maintenance in winter. At the same time, the Castor stove takes up much less space and is lightweight, and its heat capacity is high. The thick facing layer does not burst, is resistant to temperature changes and is designed for a long service life, and if desired, you can choose a stove with reinforced lining made of thicker material.
Depending on the model, the contour of the stones can be open or closed. Since the firebox and stone container are separated from each other, you can add water even while the wood is burning.

Heaters also vary greatly in volume: they can hold up to 100 kg. The larger the volume of stones the heater allows you to place, the softer and easier the steam is. Some modifications even have shelves for aromatic substances.
Reading the reviews left about the Castor stove, you will definitely come across references to the pleasant appearance of the unit. In addition to the stylish design, the manufacturer also made sure that steamers could relax and enjoy looking at the living flames. This possibility is provided by a glass door.
Models with a remote firebox allow the buyer to decide for himself how he will use the stove - exclusively for the steam room or for heating all bath rooms.

More than 100 years in search of the perfect design
Such stoves have been produced for more than a century - that’s where the quality and thoughtfulness of the design come from. And this manufacturer develops electric heaters especially carefully - they have practically no analogues in the whole world. Therefore, if you are building a small sauna right in your apartment, an electric heater from Castor is the best purchase option!
Thus, for the first time, wood-burning stoves with a characteristic signature signature began to be produced back in 1910, and from that time on, the manufacturer’s production experience only began to be enriched. Many interesting discoveries were made; the model of the standard furnace was improved more and more with each modernization. By the way, it was Kastor that released the world’s first continuous combustion heater, and from its latest developments the world was surprised by the patented CONDA effect, thanks to which the efficiency of a conventional stove increases several times - here the system constantly directs air from the steam room into the stove, and even in the steam room it will be warm when the fire had long gone out.
Of course, a priori the sauna stove from this Finnish manufacturer is designed to operate in sauna mode - high temperature and dry air. But, if you line it with bricks like a regular stove, it will not be difficult to create the climate of a real Russian bathhouse. After all, stoves are made of high quality steel, which has special heat-resistant properties.
A little about facing material
It was not in vain that the Finnish development company chose soapstone as a finish for the furnace. It does not crack or deteriorate over time. This is an environmentally friendly material that has been successfully used to make tableware.
The thermal radiation of soapstone and the human body coincides in wavelength and frequency, which has a beneficial effect on the health of steamers. Along with cleansing the body through the pores, a person also receives a session of stone therapy, which successfully copes with stress and many diseases.
Drawing of the Castor stove.
In a bath with soap chlorite, blood pressure decreases in hypertensive patients, and people with diseases of the respiratory system feel much better after the procedures. Having steamed in such a bath, everyone, without exception, notes a special vivacity and lightness in the body.
The heat capacity of the stone is high, so the heat unit produces finely dispersed enveloping steam. It prevents the air in the room from drying out, and thanks to uniform heating, you can steam equally comfortably in any zone of the steam room.
Soapstone looks beautiful, and no cement mortar is used for cladding, which allows you to do without unnecessary labor costs, and the room does not have to be washed from stubborn dirt. Installing a Kastor sauna stove is not difficult; even a non-professional can handle it.
