Heating with a fireplace oven with a water circuit. Reviews of the stove-fireplace "Bavaria" with a water heating circuit. Furnace-fireplace with a water contour with your own hands: drawings

A heating furnace with a water circuit is a versatile device designed for heating premises. Equipment in this form combines the function of titanium and the boiler.

Need to use

These furnaces serve as an optimal choice for heating houses within the cottage, as well as country houses. They are equipped with a built-in heat exchanger, which is located in the furnace. It can also be in the duct of the chimney. Some types of structures operate in the circulating mode of heated steam, which may not be available in a conventional circulation system where hot water is present.

Features of heating

Heating furnace-fireplace with a water circuit is a system that is made of cast iron or boiler steel. Such devices are designed to work under high vapor pressure. They can be used as an additional source of heat or as the main heating of the premises of the house. In such furnaces, the heat exchanger is located inside the heater and can have a certain design. As a rule, sheet steel or metal pipes are the basis for exchangers. The material must have a thickness of more than 5 millimeters.

Heat Exchanger

Heating with a fireplace oven with a water circuit usually requires a heat exchanger, which is made of sheet steel. This option has become very popular, due to the ease of processing when performing the register and ease of care. Thus, equipment owners can easily clean surfaces from combustion products that have the property of settling. A good register should provide the maximum possible temperature of the coolant, ensuring uniform circulation. If necessary, it is possible to make a heat exchanger independently, this process can not be called difficult. However, the master must have good welding skills.

Principle of heating operation

Heating furnace-fireplace with a water circuit provides for the passage of heated gases through the channels of the heating tank. They are called to transmit the energy of heat to water. In the furnace, several tanks can be used at once, with the help of which the coefficient of efficiency increases. The first tank is designed to heat water, while the second will intensify the heating until steam is formed. For maximum possible heating, it is necessary to allocate a separate room for the boiler.

Furnace manufacturing by yourself

If you decide to provide heating with a stove-fireplace with a water circuit, it is recommended to do the manufacturing of the main system design yourself. Before starting the process, it is necessary to worry about the presence of a register, a heat exchanger, a coil or a boiler. In the absence of one of the listed elements, you can purchase the missing components. If you decide to do it yourself, you will need metal pipes or sheet iron. Stove-fireplace with a water contour wall-angular "Bavaria" is also perfect for this. The minimum thickness of the steel to be used in the heat exchanger manufacturing process is 3 millimeters. The main requirement for the heat exchanger is to ensure the maximum heating of water and the uniformity of its circulation. More common and easy to use are structures based on sheet steel. Despite the fact that the area of their heating is less, in comparison with the version of the pipes, they are easier to clean from the combustion products of the fuel.

Recommendations for work

The heating system with a stove-fireplace with a water circuit presupposes the use of a certain technology for carrying out the work. For the manufacture of the heat exchanger, a pipe length of 5 x 6 x 4 cm is required. Prepare a rectangular profile and pipes, whose diameter is 4.5 centimeters. They will be needed for tapping and supplying water. The dimensions of the heat exchanger must be determined depending on the heating area and the dimensions of the furnace. The distance between the heat exchanger and the furnace should be 4 centimeters, otherwise the coolant will boil, which will cause the destruction of the entire system. If the oven is a fireplace with a water circuit, the feedback you can read below, assumes the presence of a circulation pump, then the above distance should be reduced to 30 millimeters. The thickness of the walls of the heat exchanger can vary from 0.3 to 0.5 centimeters. If the walls are smaller, it is very likely that the material will burn out, if more - the fuel consumption will increase. In order to ensure efficient heating of the heat exchanger and to level out the thermal expansion of the metal, care must be taken for a gap of 1 cm width. He will compensate for this extension. If the heat exchanger is made of a pipe, the clearance should be higher than the mentioned value. This will allow the thermal register to be heated more efficiently. Among other things, you will facilitate the cleaning and maintenance of the structure. If you decide to make a fireplace oven with a water circuit by yourself, you can prepare the drawings yourself. When installing boards that have a heating and cooking function, it is necessary to provide for the possibility of removing the furnace for cleaning the heat exchanger. In the space between it and the plate will accumulate ash, which adversely affects the operation of the system.

Brickwork must be made by specialists who have experience in this field. If you approach the process incorrectly, then the system will be broken.

Recommendations of specialists

To arrange the described heating system, you can buy a fireplace-oven "Bavaria" with a water heating circuit, but some prefer to build the structure yourself. Brick should be connected with a solution based on sand and clay. If there are irregularities and transitions, then with the help of the Bulgarian it will be necessary to cut off a small plate of the product, and then to install it in the place where there is a transition. Do not cover the area with clay, as during use it will lose strength and fall off. After the oven has dried, it is possible to install a heat exchanger, there are two options for carrying out these manipulations. The first one provides an uncapped installation. At the same time, it is permissible to use kitchen stoves and heating and cooking appliances that have a tiled surface. In this case, you need to remove the top cover and install the heat exchanger. In the wall of the firebox, it is necessary to make a hole in which the pipes going to the register will be located. The second option involves dismantling the top of the device. This method has become more popular. After installation, the appearance of the oven will not be changed.

Reviews about the furnace "Bavaria"

Furnace-fireplace with a water contour "Bavaria" has established itself among consumers. It is of high quality and manufactured on German equipment. According to users, as distinctive features are simplicity of installation, low cost and functionality. The furnaces are laid out with fireclay bricks and have a system of clean burning, which allows to increase the overview of the flame. Stoves designs are made of 6-millimeter steel, and also supplemented by a cast iron grate. Consumers like that the basis of the device is high-quality steel, from which the contour of the furnace is made. This equipment is characterized by a high heating capacity, which can reach 9 kilowatts. As users emphasize, it allows to heat rooms, the volume of which varies from 80 to 150 cubic meters.
