Furnace with a water loop Angara Aqua heats the house by means of radiators. It is used in open/closed circuit heating constructions with forced/hydraulic circulation of the heat carrier. Original device and frontal location provide accelerated heating. Softened water or antifreeze liquid can be used as the heat-carrier. Fireplace is equipped with a door with heat-resistant glass “Neoceram N-O” and “clear glass” system.

For trouble-free operation of the furnace requires the use of filters, safety structures and air vents. It is desirable to establish thermostats on radiators. Angara Aqua fireplace can be heated on its own, without connecting it to the water circuit. The system in this case must be filled. The heat exchanger in such conditions works steadily, but its service life is considerably reduced.

Furnace with a water loop is a new heating device with improved characteristics. Heat exchanger system provides high combustion efficiency and reduces the amount of soot in the chimney. Large dimensions of the fireplace allow the use of large firewood. Decorative ceramic elements are used in the design of the furnace cladding. The firebox doors are prismatic and made of heat-resistant glass ceramic.

Features of design

Let’s look at the basic nuances of construction of fireplaces with a water loop:

  • In a classic fireplace, the firebox can be open or closed. Open structures are characterized by low rates of heat transfer. In this regard, it is not rational to use them as a heat source for the heating system of the whole building. The power of such equipment is enough only to heat one room, that is, where the fireplace is installed. A fireplace with a closed firebox is more efficient. The efficiency of the system in this case will be much higher.
  • In contrast to the classic fireplace with a water loop has double walls. Inside them there is a system of heat exchanger-coil.
  • Heat exchanger, heated from the combustion of solid fuel, is connected to the heating system: the pipeline and the connected radiator.
  • Additionally the fireplace can be used for the organization of hot water supply.
  • Wood is traditionally used as fuel. However, it is recommended to use special briquettes to increase heat output and overall efficiency. They are made on the basis of sawdust. This fuel gives more heat, while leaving a very small amount of ash.

Thus, a fireplace with a water circuit performs two functions at once. On the one hand, it decorates the interior, is a significant element. On the other hand, this design allows you to heat the house. The basis of such a system can serve as a self-assembled or custom-built brick fireplace, or finished stove-fireplace. On the market there are many models of different configurations and capacities.

complex system of water heating with wood

It represents a pyrolytic boiler. which consists of two sections. In the lower section, firewood burns, and in the upper part of it circulates the gas arising from combustion. Due to the fact that in such a design, the gases do not immediately fall into the chimney, its efficiency is higher, and such a boiler consumes less firewood.

It is bundled with thick-walled pipes through which water circulates, heated by the boiler.

It should be taken into account that for the normal functioning of such a boiler, it is necessary to use only dry wood. If there is a pyrolytic boiler in the household, there should be a supply of well-dried wood.

make, fireplace, water, heating

There are systems that use hot air, not water, for heating. It passes through the contour, and is supplied to the living quarters. The cooled air, according to the physical law of convection, goes down into the special air intakes and comes back to the boiler.

Type of coolant

Since we are talking about wood stoves and fireplaces with a water loop for dachas, there is a certain approach to the choice of coolant.

Dachas in winter are usually visited occasionally, so the heating is not always on. As a result, many dacha owners try to use non-freezing fluids in the system, which even in severe frosts do not change their consistency. This means that the probability of burst pipes is reduced to zero. Although there are those who prefer plain water. But you always have to drain it before you leave and fill the system before you turn it on. Let’s face it, it’s too much trouble.

What can be offered instead of the usual water?

  • There are special liquids called antifreezes. Two types of them are used in the heating system. propylene glycol and ethylene glycol. We will not describe their technical characteristics, pros and cons, but simply say that the first is non-toxic, but it is more viscous and has a low specific heat capacity.
  • A liquid based on glycerin. They are expensive, but since you only fill the heating system once, you can afford it too. This liquid retains its fluidity up to minus 30 degrees Celsius.
  • You can use a salt solution, for example, in a ratio of 1:0,4. That is 400 grams of table salt per 1 liter of water. In this proportion, the solution may not freeze to the temperature.20С. By changing the ratio of the two components, the temperature limit can be increased or decreased.

Wiring diagrams

To install such a design in a two-story house with a usable area of 250 squares, you need to adhere to the following placement of the fireplace:

make, fireplace, water, heating
  • The structure is installed below, i.e. on the ground floor
  • The tank with water is located in the technical rooms, that is where the heat from the coolant should flow
  • In the tank coil water is heated to a desired temperature
  • From the tank (water tank) heated water flows to the radiators
  • With a good construction capacity, part of the heated water can be used for household purposes
  • The cooled water is returned to the tank through the return flow, heated and then returned to the batteries. The water intended for personal use by the inhabitants of the house circulates through the pipe system. That is, it is also periodically heated.

Scheme for the device fireplace in a conventional house (1 floor) is not significantly different. The difference lies in the distribution of pipelines, radiators and DHW. Although there are no special differences in the installation of such stoves, some nuances should still be considered. This is mainly due to the type and location of the expansion tank. Because of it such design is divided into closed and open method of connection.

Open connection method

In this system, the tank is installed at the highest point of the dwelling (attic), and there, in fact, the water flows in. Then it flows by gravity into the batteries. The system is characterized by ease of installation and total absence of additional electrical appliances.

Closed method of connection

In this option the water no longer flows by gravity into the tank, but with the help of a pump. It can be installed in any place, height and distance do not matter. This method has some advantages over the previous one:

make, fireplace, water, heating
  • Has no restrictions on the area of the dwelling for heating. That is, you can heat the house, which has a living area of more than 100 squares (in the previous method of connection such restrictions exist)
  • The number of radiators can be increased without reducing the efficiency
  • The system does not overheat

Erect the fireplace step by step

Connection to the heating system is made only after the completion and drying of the brickwork:

  • A pump is installed in the system to circulate water, instruments for subsequent measurements.
  • The structure is connected to the main pipeline. Often, the pipes are laid in the walls, for the passage of the pipe will have to break the ceiling. After installation the holes are cemented.
  • under windows, the radiators are placed on brackets at a distance of at least 15 cm from the floor, at least 3 cm from the walls, and at least 10 cm from the window sill.
  • To ensure trouble-free operation, mount the radiator in the following sequence:
  • On the wall are marked places for mounting brackets;
  • All holes are drilled;
  • Brackets are attached vertically to the wall;
  • All taps are assembled;
  • The radiator is mounted on the wall;
  • The pipe outlet is installed;
  • Inlet and outlet is provided by the installation of temperature sensors, shut-off fittings to shut off water if necessary;
  • The last place to mount the tank in case of expansion and boiling water.

The price of ready-made fireplace sample prices. What parameters does the price of a fireplace depend on.

Try to choose branded models. They are more expensive, but the quality is much better in contrast to cheaper models. The price of a ready fireplace depends on the material. Cast iron is more appreciated, retains heat well, performance up to 15 years, but also costs much more.

2 times cheaper heat exchangers made of steel. They are not as productive, but they can handle overheating quite well.

Expensive brick fireplaces, but very attractive, made designer, also resistant to overheating, fire safety.

Attractive marble cladding of the device, but it is not worth giving for a fireplace. For this money you can find a functional, and at the same time economical unit.

Is it effective to use fireplaces in the house?

Any fireplace is, first of all, a decorative element of the interior, which, thanks to modern developments, can effectively participate in the heating of rooms. So, heating the house with a ducted fireplace is characterized by a simple structure and the same simple principle of operation, and therefore costs inexpensive. However, the low efficiency of the circuit sometimes casts doubt on the entire expediency of the erection of such a construction.

The principle of operation of the fireplace with a water loop, as well as the structure of the heating element itself, more complex, compared to the previous version, which explains the high cost of both equipment and installation work. However, the efficiency of 70% of fireplaces with a water loop make this equipment an excellent alternative source of heat in the house when the main heating element (boiler) is off.

A fireplace in the house: why do we need one??

Country houses and some apartments in high-rise buildings are equipped with fireplaces. These constructs serve a number of functions, among them:

Most often, in order to ignite the fireplace use wood. They produce a large amount of heat, some of which is simply lost. A water-circulated chimney stove can help make things better. If you choose this option, then the fireplace in its capabilities can be compared to a small stove, which will allow it to be used as a complete source of heat for a small house or cottage.

You can buy this element in specialized stores, as well as to make their own hands, relying on the relevant drawings and information.

The device of a fireplace

Compared with those fireplaces with which we have associations, a fireplace with a water loop has some differences, because it must be able to heat water. What happens with a heat exchanger is that the metal tank in which the water circulates is heated by the flame. To increase the active area, the heat exchanger is made in the form of a labyrinth or coil.

The heated water does not immediately flow into the heating system main, it is accumulated in the tank. This accumulator allows you to withdraw hot water as needed. It is possible to connect a water pipe to supply the house with hot water.

Accumulator in the fireplace will lead to an unwarranted increase in the size of the latter, so the tank is installed separately, immediately after the exit of the line from the heat exchanger. The heat exchanger itself is less and less affected by the direct action of the flame. To avoid the active destruction of metal, the coil is immersed in the cavity of the fireplace, filled with water. Such a fireplace with a water jacket is increasingly used in the organization of the heating of small cottages.
