Furnaces for the house of long burning on wood: reviews and prices. Heating furnaces of continuous combustion with a water circuit

The issue of heating a dacha or apartment building in the event that the building is located far from the gas mains can be a real problem, since electricity in our time is expensive. A very good way out of this situation is the purchase of a solid fuel boiler or furnace. It is worth such equipment is inexpensive, is characterized by economy in operation. Especially popular among owners of remote suburban areas are furnaces for a long-burning house.

Principle of operation

Such equipment functions a little differently than conventional solid fuel "burzhujki" and "Dutch". Firewood in the furnace of such furnaces does not burn, but smolder, which ensures a long and quite sufficient heating of the air in the room. Smoke in the designs of this type enters the afterburner chamber, where it burns completely. This significantly increases the efficiency of the furnace. Thus, when using this equipment, you can save a lot on fuel. The bookmark of the last is usually not more than two times a day.

Heating furnaces of continuous combustion usually operate by air-convection method. This also allows you to increase productivity. Cold air from the floor of the room enters the nipples or openings in the furnace body. Heating occurs when it is moved between the skin and the walls of the furnace. Hot air exits from the nozzles or openings from above, heating the room.

Heating furnaces are used for long burning on wood, sawdust, chips, coal, peat and even household rubbish. The smoke in them is not as caustic as in conventional models.

Main advantages

In addition to economy, this type of furnace has the following advantages:

• Compact in size.
• Cheap.
• Easy installation.
• Easy to maintain and operate.
• Multifunctionality. You can use stoves for a long-burning house not only for heating your rooms, but also for cooking food. Since many manufacturers carefully consider the design of such equipment, it can in some cases even become a stylish decoration of the interior.

Models with a water circuit

Furnaces for a long burning house on firewood work rather efficiently without connecting pipes and radiators. However, for larger rooms, the additional use of highways may be the best option. In the simplest models with a water circuit on the chimney, a sealed cylinder with two nozzles is installed, to which the supply and return pipes of the heating system are connected. The circulating pump pumps the heat transfer medium. An expansion tank is used to monitor the heating medium pressure. Heating radiators can be used any.

Very often, long-life stoves with a water circuit are installed as an alternative heater in addition to a gas or solid fuel boiler.

The furnace of long burning: we make by own hands

Next, consider how you can make a simple design of this type from improvised materials. In the people such a stove is called "bobafone". It consists of the following nodes:

• Furnace chamber,
• Piston-blower,
• Covers,
• Chimney.

Production of a combustion chamber

This is the most important and important element of the furnace. You can make it from a conventional iron round or rectangular barrel for 200 liters. With this capacity, you need to remove the lid and cut through it an opening under the pipe of the piston-blower. The lid should be closed as close as possible. The more air-tight the stove, the longer it will burn wood.

Piston-ashtray

Furnaces for a long burning house on firewood work with a minimum amount of oxygen. The latter in the "bubafonuyu" is fed through an ashtray, located not from below, as in conventional models, but from above. To make a piston you need a pipe with a diameter of 100 mm. It will also be necessary to have a steel disc of a diameter slightly smaller than the barrel with a hole of 100 mm in the center. On it crosswise from the middle to the edges are welded four corners with wide shelves. Thus, channels are set up, along which the air will be distributed throughout the entire volume of the furnace. Then the blade with the "blades" is welded to the bottom of the pipe. The result is a large piston of a special design. It must be inserted into the hole in the barrel cover. On top of the pipe-scoop installed a valve for regulating traction.

Flue gas discharge

Burning stoves heating long-term burning is quite intense. Therefore, the use of a device for the removal of gases in them is necessary. The chimney is welded to the side at the top of the barrel through the branch pipe. On the street it is removed either through a hole in the wall, or through the ceiling and roof.

Installation of industrial model

The installation of such ready-made equipment as furnaces for a long-burning house on firewood is a procedure even simpler than assembling a structure from scratch. The only difficulty is that these models have to be placed close to the wall, since the branch pipe for the chimney is located behind them. In a wooden house, this can be dangerous. Therefore, the wall must first be laid with heat-resistant materials. The legs of industrial models are usually adjustable, which further facilitates installation.

The lid of the finished stoves is most often a dull metal one. However, for an additional fee, the manufacturer provides the consumer with the opportunity to purchase a transparent door made of thick heat-resistant glass. This element enhances the aesthetic qualities of the structure. Among other things, in our time are produced beautiful stoves, fireplaces of long burning.

In online stores you can buy as fairly simple small models for 7-10 thousand rubles, as well as large complex designs with a very high efficiency for 20,000 rubles.
