To date, the Greyvari furnace for a bathhouse, which includes such well-known models as Cuirassier, as well as the Rolling Stones, has acquired a fairly large base of fans. In addition, the production of these devices is the Russian company TD Technotrade LLC. In addition to the production of two well-known lines, they are also engaged in the manufacture of other samples.
Description of the Cuirassier furnaces
Naturally, if you need to consider the Greyvari furnace, then it is worth starting with the Cuirassier line, since it is one of the most common among buyers of this equipment.
The first two most important reasons why these furnaces have earned such popularity are the simplicity of design and affordability. In addition, to the significant advantages it is worth adding a fairly high coefficient of performance when burning fuel. It is due to the fact that a grate is available, as well as a drawer for ash. All these devices are quite simple, but at the same time they allow you to most effectively supply air to the lower part of the stove, in other words, under firewood.
In addition, from above, this design has an aerodynamic nozzle, which allows carbon to be burned in the upper part of the fuel combustion due to the secondary air supply. Here we can only add that even the first cubic meter of air that enters the furnace has a temperature of about 150 degrees Celsius, due to which there is no cooling from the outside at all.
Oven Feature
Ovens "Greyvari" seriously stand out from the rest by the fact that even raw firewood can be used for kindling. This feature of "Cuirassiers" is ensured by the same supply of already warmed and dry air, which dries the material.
Of the minor, but rather pleasant, features, it is worth noting that the steam from the Greyvari metal furnaces is softer and more pleasant than others. Although this is not even liked by many attendants who bought such a product, but a grate.
Its peculiarity lies in the fact that it is not cast from cast iron, as most other manufacturers do, but consists of steel beams. As you know, steel expands under the influence of sufficiently high temperatures, and therefore it is as if self-cleaning from ash. From the point of view of design, everything is quite simple, but at the same time convenient and original.
Other benefits
Reviews about the Greyvari furnaces from those who purchased this product also speak of such an advantage as a significant viewing area. It is even larger than the models that were previously considered premium. This was facilitated by the fact that the front wall of the ash pan, as well as the portal, are made of mirror stainless steel. In order to make installation and transportation convenient, the portal is removable.
In addition, the Greyvari bathhouse of the Cuirassier range also has an unusual protection for the back wall of the combustion chamber. This wall is a special aerodynamic screen, which is made of high quality and heat resistant steel. It is through this element that air will enter inside, which is used for secondary afterburning.
The Greyvari bath stoves have another design feature, which has become a significant plus - special protective elements for the bottom of the furnace. They are often called ash cushions, and their main role is the natural thermal insulation that is created after fuel burnout.
Models "Cuirassier"
Models of Greyvari furnaces Cuirassiers include quite a few models. This includes the usual "Cuirassier", "Swedish", Finka and Corbis.
In addition to these models, there is also a separate product line, which includes four Rolling Stones devices.
As for the general characteristics of these furnaces, they can be used to heat a room with an area of 6 to 32 cubic meters. All of them are made of the same structural steel, its thickness does not exceed 0.6 cm. In addition, any Greyvari heating stove is designed for a chimney with a diameter of 115 mm. A more detailed description is in the description (instructions) of each model separately.
Finka
One of the eight groups of different Cuirassiers models is the Finka line, which combines three more varieties. However, they also have certain identical characteristics, which combines them into one collection.
This should include such a feature as a firebox directly from a twin room. This is one of the old ancient Finnish traditions, hence the name of the line. In addition, they have the additional ability to ventilate the steam room, for which they are equipped with a special retractable ash pan.
Further, everything is quite simple. Firewood is used as fuel. The tank and heat exchanger are mounted on a pipe, which also has a diameter of 115 mm, and all devices are made of structural steel with a thickness of 6 mm.
The only thing worth adding is a comment from the manufacturers themselves, who recommend the use of this type of stoves complete with a steam generator or an economizer.
"Swede"
Here you can immediately say that this variety is represented by only one model - this is "Cuirassier 15 Swedish". As in the case of the Finks, this model has the possibility of additional ventilation of the twin room.
A distinctive feature of this stove was spotted by the Scandinavians a very long time ago and is that the unit maintains hot, but at the same time fresh air in the room. The device draws air from the steam room directly into the furnace, which helps to reduce the pressure in the steam room. It turns out that fresh air enters the oven, and the one that has already been spoiled by breathing is also absorbed, but after that it is taken out. The last thing that can be noted at the "Swede" is that the furnace firebox also comes from the steam room.
Corbis stoves
If we talk about the “Cuirassiers” models of the Corbis line, then here a distinctive feature as the presence of an open octagonal heater, which is made in the form of a grid, immediately comes to the fore. Due to the presence of such a design, there is the possibility of round masonry with a total weight of up to 220 kg. As for the kindling of such models, users in the reviews note that it takes a long time, but after that a warm period also remains warm. A fairly mild climate will be created inside the steam room and it is very convenient that there is no need to often throw firewood.
In addition, it is worth saying that there are some advantages that are provided by the presence of a circular laying of stones. For example, infrared radiation from a red-hot metal will be less rigid, and you can pour over them from any convenient side. At the same time, the volume of steam will be quite large, but at the same time, it is characterized by its softness and freshness.
As for the lineup, Corbis include 4 different furnace variations.
