Prolonged combustion furnaces with a water circle

Effective heating is crucial for keeping our homes comfortable during the winter. Furnaces with a water circulation system for prolonged combustion are one novel approach that is becoming more and more popular. These cutting-edge heating systems have several advantages, including better heat distribution throughout the house and higher efficiency.

Prolonged combustion furnaces run at a lower, more constant temperature than traditional furnaces, which depend on brief, intense heat bursts. In addition to ensuring more economical fuel use, this slower burning process produces a warmer home that is more stable and consistent. These furnaces can provide pleasant heating for extended periods of time without the need for frequent refueling by utilizing the power of prolonged combustion.

Furnaces that have a water circulation system have the unique ability to use thermal energy more efficiently. Under these systems, the furnace heats the water, which is then distributed throughout the house via pipes or radiators. The hot water releases heat as it moves through these channels, warming the air around it. By removing cold spots and ensuring uniform warmth throughout the house, this technique of heat distribution enhances comfort levels.

Long-term combustion furnaces with a water circulation system have advantages for the environment in addition to increased comfort. These systems emit fewer emissions than conventional furnaces because they burn fuel more slowly and transfer heat energy more efficiently. This lowers the household’s carbon footprint while also improving everyone’s health and the quality of the air.

Furthermore, adding a water circulation system gives you even more heating options to choose from. Homeowners can install modern radiators that complement any interior design or connect the furnace to radiant floor heating, which offers opulent warmth underfoot. Customizable heating solutions allow homes to customize their systems to fit unique requirements and tastes.

The best heating furnaces of long burning with a water circuit for the house

Connection of the battery

Despite all of its benefits, traditional stove heating is unable to address a number of important issues. In order to minimize these "minuses" and create the most comfortable environment possible, long-burning furnaces with a water circuit for the house eventually appeared. Boilers and stoves made by you, as well as completed items from various manufacturers, exhibit similar designs.

Take note! Pets are attempting to link the fireplace and water heating systems. These gadgets’ widespread appeal can be easily explained: they let you set the ideal temperature at home while saving gasoline. The house is simultaneously heated by the liquid coolant in addition to the furnace body.

The working principle of a long-burning stock is comparable to that of a solid fuel boiler. They operate on the basis of the pyrolysis principle. When it is used, flammable gases are produced in addition to the fuel being combined. As a result, the wood furnace operates at its highest efficiency for a longer amount of time on a single fuel bookmark.

A cast iron stove with two chambers is the structural component of a long-burning stove. Gases burn out in one chamber while solid fuel smolders in the other. Ash is created when combustion products pass through the grates. The ash-free door functions as a control regulator in the most basic models; the more open it is, the more intensely the firewood burns.

The furnace door is used to load the fuel. An automatic fuel loading system can be fitted to models that run on coal or pellets. Wood, pellets, coal, peat, and sawdust can all be used in cast iron heating stoves.


These units come in a wide range of varieties:

  • By purpose – heating, bath, universal, hobs.
  • By the type of fuel.
  • According to the case of the case – steel, cast -iron, brick, combined.

Gas -generating furnaces

Gas generating furnaces are distinguished by several attributes.

  • Economy. On one fuel bookmark, the furnace works for about 12 hours.
  • Compact sizes.
  • High efficiency – about 85%.
  • The ability to adjust the intensity of combustion.
  • The possibility of using different types of fuel.
  • Simplicity of connecting a water circuit.

The decision in favor of gas-generating furnaces appears to be clear-cut. However, prior to installing a comparable model, you must consider several subtleties:

  • Significant requirements for the arrangement of the chimney.
  • High probability of condensate formation on the walls of the chimney.
  • Manual adjustment to which you need to get used to. Only in this case can all the above advantages be achieved.
  • You can use different types of fuel, but there are a number of requirements, the non -compliance of which can lead to a deterioration in the quality of heating.

Gas -generating homemade

Even though there are many commercial models of gas-generating furnaces, people frequently build these structures themselves. In domestic production, as long as all manufacturing regulations are equivalent to the final products. The existence of two combustion chambers is the primary distinction between a gas generator furnace and a conventional furnace. There is little difference in the remaining steps of the manufacturing process.

Standard sheet metal can be boiled to make the case. Simultaneously, a standard metal barrel with the required capacity could serve as an appropriate substance. The body is attached to a steel pipe, which serves as an adjustable component. A grate divides the two cameras. Installing the heat exchanger is necessary before connecting the water circuit. Refractory paint is applied to the surface to protect the structure.

Pellet stoves

Gas generators come in the form of pellet furnaces. It is intended to function with wood granules, or pellets. The existence of a bunker for fuel loading distinguishes these furnaces from one another. Furthermore, a significant benefit of these models is their high level of work automation. Granular feeding is done with a self-regulating screw or pneumatic device as they burn out. It is possible to control both the fuel supply and the operating modes.

The steel used to make the hot water tank is resistant to harsh conditions and high temperatures. The tank’s size is not limited in any way. Actually, they are solely reliant on the cast-iron slab’s measurements. Nozzles connect the water tank to the entire system. There are two locations for installation: either at the furnace chamber’s intersection with the chimney, or as near to the chimney as feasible.

With a water circle or without?

Furnaces that produce gas have shown to be a reliable heating source even when they are not connected to a water circuit. As long as the unit’s power is selected correctly, he will be delighted by the warmth and comfort. You can select a combination model that includes both an oven and a hob based on the particular operating conditions. These gadgets are widely used.

Generally speaking, you don’t need an extra water circuit when using a gas generator furnace. On the other hand, by utilizing two distinct heating networks—a stove and radiator systems with liquid coolant—its connection will create more comfortable surroundings.

Unlike brick furnaces, connecting a water circuit to a cast -iron structure is not difficult. The heat exchanger is installed above the firebox. Such a shirt will go through the furnace, providing water heating. The coolant, circulating through pipes and radiators, makes the heating of a country house more efficient. As you can see, it is better to use cast -iron stoves with a water circuit. At the same time, as practice has shown, it is better not to integrate the heat exchanger in brick design. This is due not only to the complexity of installation, but also with a number of nuances that are already revealed during the operation of the device.

In actuality, installing gas-generating furnaces simply involves placing them in the designated location and connecting them to the chimney. Legs on industrial models can be adjusted to make installation easier. The chimney connection is an installation feature. In these models, the output pipe is usually situated at the back. The furnace must be installed as close to the wall as possible to facilitate connecting to the smoke excreting channel.

This can lead to a higher risk of fire in a country home made of wood. It is worthwhile to use refractory materials to protect wooden structures in order to reduce risks.

The ability to be integrated into the current heating system is what makes gas-generating furnaces unique. Assume a gas or electric boiler serves as the foundation for an autonomous network. It can easily incorporate a hot water tank or a water circuit into a solid-fuel stove. This integration will provide a backup heat source in the event that the fuel for the primary boiler is unavailable.

Fascinating, but the range of contemporary stove models allows you to solve any issue, including design-related ones. Even a fireplace is readily available for purchase. An industrial fireplace with this feature will function similarly to a regular gas generator stove that has a built-in heat exchanger. However, its exterior design will closely resemble a traditional fireplace at the same time.


Long-burning gas generator furnaces are a good fit for heating a rural home. By employing diverse fuel varieties, seamlessly integrating into various systems, and having a range of designs, they can effectively address nearly all issues related to maintaining a pleasant home microclimate and hot water supply.

Prolonged combustion furnaces with a water circle

A long-burning oven is frequently used to efficiently heat and supply hot water to a private residence. You can either buy it already completed and staffed, or you can do it yourself.

The stove operates on a multi-stage combustion of fuel principle. When a lot of fuel (firewood) is used at once during operation, the fuel smolders instead of burning right away because it is receiving insufficient oxygen. The presence of oxygen (air) in a dedicated compartment causes secondary burning of the flammable gas produced during the burning of wood. Since the fuel in these stoves produces combustible gas, they are also known as gas generators.

Should the furnace feature an integrated water circuit, the heat produced warms the water within the heat receiver, which is then dispersed throughout the entire home’s heating system.

Modern buildings have enough power to continuously heat incoming water, negating the need for a hot water storage tank.

Example: The "Teplodar" company’s solid fuel version. Unlike brick furnaces, it can be connected to an existing water heating system of the building with a specific contour; all that needs to be done is replace the equipment (such as a heating boiler with a centralized fuel supply). Furthermore, a stove of this kind can be incorporated into a private home’s interior design to highlight a particular style.

Advantages of prolonged burning furnaces

"Teplodar" is a reputable manufacturer of long-burning furnaces with a water circuit. The company produces a wide range of products based on years of experience in the production of heating equipment. A range of stoves featuring a Teplodar water circle and long-burning furnaces, constructed in compliance with all regulations, offer all the primary benefits required for home heating:

  • Increased autonomy, the operation of the furnace does not depend on the main gas supply or electricity.
  • Economy – firewood is used as the main fuel (affordable and inexpensive option), has a small consumption of up to 10 hours on one bookmark.
  • Due to the two -channel watering system, the stove efficiency reaches 85 %.
  • The ability to use additional types of fuel (coal, branches, chips, briquettes).
  • The controlled mode of operation is divided into two types: intense, for quick heating of the room and economical, serves to maintain heat in the room.
  • Compact size, reliability, durability and ease of operation.
  • Convenience in the installation.
  • Simplicity of connecting a water circuit to the heating system of a house with your own hands.
  • You can use large logs, respectively, you do not often need to chop firewood.

Water circuit-equipped heating stoves are manufactured with contemporary quality control technologies and adhere to all safety regulations. A heated space can have a maximum volume of 300 m3. Teplodar stoves can be readily used for a variety of heating applications in greenhouses, bathrooms, garages, and other household extensions. One intriguing aspect of them is that they can be used for cooking because their surface is made of cast iron tiles.

Production of a furnace

Even though finished goods have a large market, stoves are frequently collected independently. The primary benefit of DIY projects is their low cost, as store options can be quite expensive.

You need to be skilled with a welding machine and metal in order to build a safe stove that can heat a house on your own.

The stove diagram and all required materials must be ready in advance.

From a manufacturing perspective, the furnace’s firebox door is the most challenging component to design. It should be constructed with efficiency, have a strong castle that shuts tightly, and not emit heat or combustion products. A long burning happens with a low air supply, so an additional air supply damper must be included in the door’s design. More larger firewood can be used in furnaces with larger doors.

To ensure that the door does not lead and does not deal when heated, you must first cook a box the size you require out of the metal sheets and attach a fixing collar (5–10 cm high) to one of the planes. Above the box, a rectangular chimney hole is cut. Clay is poured into the space created by the welding of a second collar, which has a diameter greater than the chimney pipe (forming a clay lock).

A side to support stones on top can be added if the furnace is used in the bath.

With a small supply of air, premium firewood can burn for three to five hours in a do-it-yourself stove.

Option for a metal barrel furnace

This is the long-burning oven option. can be designed with a water circuit using only your hands. You will need sheet metal, pipes of various diameters, a 200-liter steel barrel with thick walls, and additional tools for him. The barrel’s top cover is removed, a damper is installed inside, and a chimney pipe is welded to the wall.

A small diameter pipe that can sink into a barrel is welded with a lid to bring in air. The entire structure is positioned in a barrel all the way to the top, with the pipe being made on top of the damper. The first lid to be sawed from the barrel has clamps and handles. As combustion products are released through the chimney, firewood is piled on top.

The empty space at the barrel can be filled with water and heated by the internal structure if a second wall is built. Then, pipes are welded into the base to connect to the heating system.

Long burning furnace with a water circuit

A long-burning furnace with a water circuit is a stylish and contemporary heating device that requires solid fuel for heating. It is a worthy addition to any space. Because of its connection to the heating system, this kind of device will create a cozy environment not just in the room where it is placed, but all over the house. Such a furnace’s design incorporates a feature that facilitates the heating and passage of a substantial volume of water through pipes and radiators.

Design features and principle of work

The operation of the furnace with a water circuit follows the same principle as other long-term solid fuel burning devices: "squeeze" the most thermal energy possible from a single firewood laying. The device’s components expand into wood through the pyrolysis process, extending the burning time to several hours. Low oxygen levels and high temperatures cause gas to form, which when it burns in the living room for a long time, maintains the temperature.

A hermetically closing shutter is erected in the combustion chamber to prevent air from interfering with the slow smoldering of the coal and the burning of the gases. This component creates forced ventilation or, to put it another way, regulates air flow. Therefore, the furnace’s flame will be more intense the wider the damper is open. The process of the coals in the stove slowly smoldering starts when the firewood is burned, and the damper shuts tightly, blocking airflow.

We suggest watching the following video to get a clearer understanding of how pyrolysis works:

They are used as fuel to guarantee that a long-burning furnace with a water circuit operates as follows:

  • firewood;
  • brown coal;
  • pallets;
  • Evodrova;
  • granules;
  • chips;
  • other waste of woodworking and agriculture.

The furnace door allows for the loading of all of this material into the apparatus. The process of supplying the firebox with some more contemporary fuel types—such as pallets, wood granules, and Evrodrov—is automated. By connecting to the fuel bunker furnace with an appropriate energy carrier, they are able to achieve their load. There are furnace models with similar designs that already have a similar device.

Design features

The design of the furnace has two cameras. With the aid of a special burner, pyrolysis gas produced by the burning of fuel in the first compartment is transferred to the second, where it burns completely over time. There is an ash-filled area in the first chamber beneath the grate-equipped bottom, where leftover combustion products build up in the furnace.

This type of prolonged burning furnace is distinguished by the water shirt that surrounds the combustion chambers. As a result, there is a space between the furnace’s two walls where circulating coolant is kept warm until it enters the heating system to heat the entire house.

With a water shirt and circulation pump, prolonged combustion furnaces effectively fulfill their purpose of heating the home, either on their own or in conjunction with other gas or electric-powered heating appliances. These stoves can be used for more than just setting up warm floors; different devices can achieve the required temperature in slightly different ways.

Manufacturers of furnaces have recently started to incorporate other features, like the ability to cook, into their products. To do this, the hob is equipped on the furnace’s upper plane. Even a tiny built-in oven is a feature of more sophisticated furnaces overall.
