Fireplace water heating circuit - is an improved modification of the heater on the solid fuel. In our time it is called the fireplace is solid. Such a heater is found in cottages or in apartments on the first floor, since it is not required to fill in a powerful foundation under it.
species
The main elements of this device is a furnace niche and chimney. They are divided into two different connection systems: open and closed.
- open fireplaces are designed to quickly heat the room, but they have low efficiency. They are set for visual enjoyment fire.
- The efficiency of heating appliances in a closed type up to 90% of heat. Furnace recess closes the flap of the heat-resistant quartz glass.
The hydraulic design of the heating water circuit includes a chimney stove for solid fuel (wood and coal). Equipment with a capacity for the coolant is installed in a central room, it is joined hydraulic pipe of the heating circuit, and through them there is heat transfer to adjacent room.
- This heating unit operates to supply hydraulic heating hot water of about 800FROM.
During the combustion of sawdust briquettes in a heating liquid system in the tank is heated and enters the hydraulic system for heating the other rooms.
View of the fireplace, and it heats the power
These fireplaces are different in their appearance, the front side has a different modification. The door may have:
- direct;
- panorama;
- prismatic glass.
These heaters are manufactured in different capacities such as 12,15,19 and 24kW. They are selected depending on the size of the heated space. To determine the required parameters must be considered that 1 kW is 10m2 heated area.
Fireplace with a water jacket belongs to the hydraulic system of closed type. Unlike the fireplace single wall, he has double walls, the space in which the heat exchangers are arranged wavelike.
It is attached to the tubular heating hydraulic system that allows the heater to become a key element to heat the house, but still it is used as vodosogrevayuschee equipment for all rooms.
with water jacket design has a different circuit connections - open or closed.
- An open system is created under a pressure of about half an atmosphere, and the wall thickness of the connected pipe must be at least 4 mm.
- A closed system is constructed so as to withstand the pressure - 2.5 bar and the wall thickness must be at least 6 mm.
Joining the fireplace to heat the hydraulic system
To open hydraulic acquire the expansion tank, which is installed near a heating structure. Circuit with coolant running in the likeness of communicating vessels. In this case, the coolant warmed in the fireplace and enters into the hydraulic system through the heating heat exchanger.
A closed system is connected without a membrane tank, the water is passed directly to a heating structure.
Water fireplace, heated with wood, can be used as fuel briquettes made from sawdust. This type of fuel is actively used in our time, as the heat of this material is much higher than that of wood and ash from them is a small amount.
Specifications
What design elements are included in the home heating fireplace with a water circuit? Consider this question in detail.
Fireplace with water heating - a housing, made of cast iron or steel boiler thickness of 5 - 8 mm, from the outer side is covered with fireproof paint. It has a built-in container volume of 50 - 90 liters. By this construction, the water circuit can be connected with the internal displacement volume 11% less than that accommodates the heating tank construction.
The inner walls of the furnace are lined with ceramic tiles. Between the furnace wall and the outer lining of the heater are ducts through which flows the oxygen for combustion improving fire, and in this place the heat exchangers are integrated.
Basic elements for connection to the water jacket of the fireplace
The following components are used for the full operation of the system:
- diaphragm expansion tank;
- copper pipe tapping system in the fireplace;
- sensor - automatic, dropping the temperature in the pipes when she scored 950FROM;
- valve for excess temperature power drop 2,5 bar - protects from fire in high-pressure hydraulic nutri;
- couplings and valves for mounting them become common system embedded in the heat exchanger device.
Assembling the hydraulic heating
Before any installation, you choose what system you use, open or closed.
Connection of the heating structure is as follows:
- The heater is installed in the basement or on the first floor of the building - technical room.
- Above it is mounted barrel (gidroakkomulyator) with coolant. Its purpose - to maintain a smooth change in the fluid pressure in the system.
- This is followed by assembling the hydraulic pipes open.
Diaphragm expansion tank is installed in the attic of the house, the heat exchanger water flows due to the forces of gravity. Excess heated coolant flow back to the tank. The liquid is warmed in a device ondulated conduit which is installed in a recess of the furnace.
Remember! This hydraulic assembly is simple and using it to warm a large area will not work.
Most use a closed system, wherein liquid from the diaphragm expansion tank flows into the heat exchanger, which is installed closed boiler part.
- Water heated to 80 In this system - 900C and is pumped through the circulation pump through the pipes into the drive, followed by pipes to the radiators.
- To maintain the heater from high temperatures in the hydraulic system in the rear part of the furnace is embedded bent pipe in which cold water flows, if necessary.
The pipe coming out to the surface of the heater, the temperature sensor is installed, which in the case of exceeding 950C in the water circuit, releases water into the sewer.
To make a connection to the existing, established brick fireplace can be financially profitable. As for this, consider the pipes under the cold liquid and to conduct complex calculations water system for connection to heating.
Summing up, it is worth recalling that if the fireplace will heat your space not only by air way, but also through a heat exchanger and a water jacket, then it is best to be planned at the beginning of the construction houses.
