A wood-burning cast iron stove will create warmth and comfort for your dacha!
The use of cast iron as a material for the manufacture of heating devices has been widespread since Soviet and even earlier times.
This is due to service life material, cast iron device retains and releases heat much longer.
Despite the fact that the material has its own disadvantages, cast iron is not going to give up its positions and is now actively used for the manufacture of heating devices, including for country houses.

Advantages of the material
Cast iron has a number of undeniable advantages:
- High efficiencyIn cast iron it reaches 80-85%, this is the highest indicator compared to brick and metal, it is achieved due to high heat capacity - this material gives off heat a few hours longer.
- Protection against deformation. Cast iron has a low rate of expansion when exposed to high temperatures.
- Protection from damage. The type of manufacturing of cast iron parts does not provide for welding seams, which are weak points of steel furnaces.
- Corrosion resistance. Cast iron does not suffer from rust, condensation, and is not oxidized by combustion products, which protects the walls of the firebox from burning through. This metal no protective coatings required.
- Long service life. Cast iron stoves have an active period of use not less than 35 years old (and in some cases much longer).
Attention! The disadvantages of cast iron include its brittleness when exposed to sudden changes in temperature — in this case, the metal can easily crack, and repair of damage is impossible, since all cast iron parts are made only by casting.
The main types of cast iron stoves, an analogue of a brick fireplace
Cast iron heating devices for summer cottages are divided into two main categories: for heating And with additional cooking function. There are open-type devices that are analogous to a brick fireplace. The most effective in a country house is considered to be long burning stove.
Heating: wood-burning, with a water circuit, long burning
For high-quality heating of a room, different types of devices are used:
- A regular wood burning stove It is used in small country houses because it heats well only room space, in which it is installed. The device provides the ability quickly warms up the room and retains heat for a long timeOne load of firewood is enough to heat the air in the house and maintain the temperature throughout the night, which is very convenient when traveling to the country.
- Furnace with water circuit. Most often, such equipment is used for large houses with several rooms. Connection to a radiator heating system or installation of heated floors ensures uniform heating of the room and ease of maintaining the desired temperature. The devices are very convenient for permanent residence in a country house and allow you to provide your household with hot water.
- Long burning heating device has a more complex device with two chambers, providing for the re-burning of gases and other combustion products. Such equipment is suitable for heating a large area, connection to a water circuit is possible.

Stoves intended only for heating are distinguished by their power and can also be installed in a separate room.
Heating and cooking
Heating and cooking devices are a wonderful option of combining functions, very profitable for small country houses. They perform both heating of the premises and provide the opportunity to cook food and heat water for household needs. Using such a stove is often the only way out in remote areas where there are interruptions in electricity supply, and there is no possibility of connecting gas supply.
Choosing a stove for a summer house
In order to choose the right equipment for heating a country house, There are several important criteria to consider:
- Area of the premises. The main point for the correct choice of the power of the future furnace, usually the calculation is carried out according to the formula 1 kW per 10 sq. mIt is necessary to take into account the height of the ceilings.
- Degree of house insulation. The thickness of the walls, the materials used for insulation, the number of windows, and the roof structure are all important.
- Possibility of correct installation of the chimney.
- Volume of the combustion chamber of the device. Affects the power and frequency of fuel loading.
- Necessary functions. Do you only need heating of the room, the ability to heat water, cooking?
- Design. Should the stove complement the interior, be its significant part, or will it be installed in a separate room.
Depending on the size of the house and the required functions, the type of stove is selected - for small dwellings a device with a closed firebox and hob will do, for country houses with several rooms It is better to install a more powerful furnace connected to the water circuit.
Cast iron long burning wood stove
A typical wood stove requires adding wood at least every every 4 hours, this naturally causes inconvenience, and the house has time to cool down during the night. Therefore, it is more expedient to use a long-burning device.
Operating principle
The device differs from a conventional oven double combustion chamberIn the first section the process takes place burning wood, and in the second chamber it is carried out afterburning of gases and smoke released during combustion. For more efficient operation of the equipment, the air supply to the first chamber is restricted immediately after the flame flares up. The wood begins to smolder, more smoke is released. This type of fuel combustion is called pyrolysis.
Important! It is advisable to install a thermostat on a long-burning device and equip not only the chimney, but also the air duct to the street in order to avoid burning out oxygen in the room.
Advantages
The peculiarity of the device's operating mode based on the pyrolysis process allows to reduce the frequency of adding firewood several times - one load may be enough at 8-12 o'clock. While the heating power is not inferior to a conventional furnace, the long-burning device will allow you to save significantly on fuel. The pyrolysis furnace can also operate in normal active combustion modeTo do this, it is enough not to close the air duct damper.
Device with a hob
Cast iron cooktop units typically contain 1-2 burners and an oven. The burners in a hob can be either of a fixed diameter or a set of rings that can be removed to reduce or increase the burner size.

For such equipment it is recommended additional protection against damage (hot cast iron can crack if cold water is spilled on it), it has proven itself well in this capacity cladding with tiles.
Designed in this way, the stove will not only decorate the interior and ensure a longer service life of the cast iron firebox, but will also contribute to comfortable cooking process - you won’t have to withstand too much heat from the working oven.
Rules for safe use
For proper operation of the cast iron stove the following conditions must be met:
- Podium made of heat-resistant material additionally protects the floor from the pressure of massive equipment.
- It is advisable to complete wall cladding with ceramic tiles in the place where the device will be installed, or use other non-combustible material.
- The chimney must be covered with a protective cap on top.to prevent dry leaves from getting into it.
With proper care and operation, a cast iron stove will become a highly efficient and durable heating system for a country house.

Comments
The stove was in quite satisfactory condition, only the legs were broken off. I installed it on a pedestal made of bricks and covered it with bricks.
Everything is fine, but the room warms up slowly. What can I come up with to make the room warm up faster?
