Currently, there is a fairly large variety of heating appliances, with which you can efficiently organize independent heating system. Consumers' desire to reduce dependence on centralized services for heat and energy supply is understandable. Saving money spent on gas heating is an essential factor to pay attention to the residents of private homes.
In addition, the technology is not always able to connect to a central gas supply. In this situation, the main roles beyond boiler equipment, for solid fuel. Powerful solid fuel boiler is a great alternative to gas appliances. Manufacturers have managed not only to improve the processability of the heating technology of this type, but also to achieve a significant increase in the efficiency of solid units. High power and high efficiency coal-fired boilers different types of fossil fuels and fossil fuels, make such devices popular and popular.
An important aspect for that would choose the right heater for your own needs, is to calculate the power boiler. A closer look at how to do it and what to look for.
What you need to do the calculation power of the heating device
Appearance of heating equipment, high technical specifications stated in the data sheet, give only a superficial understanding of the technical capabilities of the solid fuel boiler. The main parameter influencing the choice, the power of the device is. In pursuit of her, we sometimes make hasty conclusions and overpay, gaining powerful units that do not meet the real needs and objectives.
Price-Quality + thermal output ratio is crucial for any heating equipment. Manufacturers offer a consumer heating boilers wide variety of models, each of which corresponds to specific operating conditions. Despite this, the hospitality in each case it is important to have an understanding of how to work the heating device and that the resource is consumed heating unit. Designed with the needs and the design features of the premises setting work on the radiator solid fuel, the correct installation of equipment, will bring the home heating system to the optimal condition work.
Many consumers wonder. How to calculate their own power own solid fuel boilers, which would in the future had no problems with the heating system. Nothing complicated. With a minimum of knowledge and effort, you can get preliminary data, giving an idea of what should be the heater and it is better than to sink.
Power boiler - the theory and the real facts
Heating apparatus, coal, wood or other organic fuel has a specific work related to the coolant heated. The quantity of boiler equipment is determined by the volume of heat load, which is capable of supporting solid fuel boiler the combustion of a certain amount of fuel. The ratio of the sacrificial fuel quantity, the volume of heat released at optimum operating conditions and equipment is the power boiler.
Correctly matched the heater power, can not provide the required boiler water temperature in the heating circuit. Low-power solid device will not allow a single system to fully realize your needs in terms of housing and providing domestic hot water heating operation. There is a need to increase the power of a standalone device. Powerful device on the contrary, would create problems during operation. We'll have to make design changes to an existing heating system for reducing the thermal load of the solid heating device. Why in vain to burn precious fuel, if there is no need for such an amount of heat.
For reference: exceeding the capacity of the boiler heating system technological parameters, it leads to the fact that the coolant in the circuit will diverge impulsively. Frequent switching on and off of the heating unit leads to excessive fuel consumption, lower operating capacity of the heating equipment in general.
From a theoretical point of view, to calculate the optimum boiler equipment operation is easy. Tentatively accepted that 10 kW enough to heat the living area of 10 m2. This indicator is taken with the high thermal efficiency of the building and standard design features of buildings (ceiling height, glass area).
In theory, the calculation is made on the basis of the following parameters:
- heated space area;
- the power density of the heating equipment to heat 10 sq. m, taking into account the climatic conditions in your area.
This chart shows the average parameters of the boiler equipment used by consumers in the Moscow region:
| The area of a dwelling house, other buildings, m2 | Recommended power unit, kW |
| 60 — 200 | to 25 |
| 200 — 300 | 25 — 35 |
| 300 — 600 | 35 — 60 |
| 600 — 1200 | 60 — 100 |
thermal load parameters optimal look on paper, in theory, which is not enough in relation to local conditions. Selected unit in reality should have excess capacity. In reality, it is necessary to focus on equipment that can operate with a small reserve of power.
On a note: Excess power solid fuel boiler allows you to quickly reach the optimal mode of operation the entire heating system in the house. Additional resources must exceed estimates by 20-30%.
The actual load performance solid aggregates depend on the set of a variety of factors. The climatic conditions of the region in which you live can make adjustments when choosing a heating boiler. For the middle band is considered to be optimal following power boiler equipment parameters:
- Flat urban apartment - boiler with output load 4,16- 5 kW;
- for a one-bedroom apartment - equipment denominated in 5,85-6 kW;
- two-bedroom apartment will be enough to have the unit 8,71-10 kW;
- four-room apartment, private house residential demand for central heating boiler parameters in the 12-24 kW.
Important! When it comes to the installation of boilers for solid fuel in private homes and residential buildings in the country, it is necessary to focus on devices larger technological capabilities. For heating and providing hot water residential building area of 150 m2 and a need to put a solid fuel boiler 24 kW or more. All depends on the intensity of the heating system and the volume of domestic hot water needs.
Choose heating technology should always be individual, based on calculated data and their own needs.
Options for calculating power of solid aggregates
The accuracy of your calculations depends on the consideration of all factors and indicators that we have been paying attention to the above. For greater clarity, you can perform a number of actions, which will give an idea of how it's done.
The specific power of the heating device is denoted by the letter W. For the regions of our country with a harsh climate, this parameter is 1.2-2 kW. In southern regions specific value of the heater varies between 0.7-0.9 kW. The average value in this case is 1.2-1,5 kW.
To begin, we define the area of the premises, subject to heating. Further, the data area is divided by a specific amount of power boiler installed in a house in a certain area. The obtained result is divided by 10, calculation of the theoretical ratio of consumed power of the heating equipment for heating 10 sq. meters.
For example: count limit load of the heating boiler operating on carbon for an average residential house, an area of 150 m2.
- Actual size of - 150 sq. meters.
- The specific output of the heating apparatus for heating 10m2 is 1.5 kW.
For use the following formula: W = (150 x 1.5) / 10. As a result, we get 22.5 kW. The resulting value is the starting point for what would have to pick up a stand-alone boiler for solid fuels, taking into account the technological possibilities of the heating system and its own domestic needs.
On a note: finding a similar model of heating equipment, throw with 20-30% of the power to enhance the technological capabilities of all heating equipment. From the number of tenants in the building depends on the load on the WAN system, a comfortable temperature in the house, provided that the boiler is operating at optimal conditions.
A similar scenario is possible to calculate the required resource the heater for the house of any size. Always keep in mind the climatic conditions and their own queries to the boiler equipment.
The optimal choice of heating equipment - the nuances and subtleties of the issue
Find out for yourself the necessary parameters of power coal-fired boiler, which will be in your home, you can begin to design and installation of the heating system. You should know that the declared data on the thermal load hardware resources have an impact on the cost of the unit. Heating low-power devices have limited technological capabilities and are primarily designed for heating small areas of the premises. It may be summer houses, saunas and guest country of construction type.
If necessary, the question arises as to maximize the functionality and efficiency of the solid unit. In this case, there is a reasonable technical and engineering solutions, by means of which an increase in the boiler efficiency will give a tangible effect.
On a note: significantly increase the efficiency of the device can be installed in a chimney through an additional heat exchanger which receives heat from the outgoing combustion of volatile wastes. PowerSaver (additional coil) will increase to 20-30% of the nominal capacity of the boiler equipment.
Use for self-heating of houses solid fuel boilers high power impractical. Such equipment is bulky and requires the installation of special facilities large area. Given the size and immense power, industrial boilers, should be aware of the significant costs of the fuel resource.
This technique is ideal for heating an industrial scale. Much heat is required for heating large industrial facilities and buildings. Solid units with high heat demand in the enterprise.
findings
Selection of heating equipment - a difficult task and responsibility. Do not immediately chase the models of solid aggregates, which have a large capacity. In some cases, for heating of an apartment house is enough for installation of the unit with output parameters in the 24-36 kW. At a temperature of -30 window 0With such boiler will enable to create the indoor temperature of + 20-22 0C, and heat the water in the heating system to figures 40-45 0FROM.
In each case, you can make a choice in favor of one or another type of heating equipment
Large boiler capacity may be required in peak situations where the climatic conditions are forced to work the heating system in the emergency mode. However, such situations are not systematic, and most of the time your heater will operate at lower modes. If you have a large hot water consumption is expected for domestic purposes, it is necessary to immediately focus on the more powerful equipment. The modern private houses more than 50% of the capacity of the heating equipment is to provide hot water at home dwellers. Connecting the heating system "warm floor" as well to pay attention to make boilers with more power.
Pick up the boiler must not only based on its actual power. It plays the role of the operational capability of heating equipment, the method and the quality of service of the boiler equipment. Using the best fuel for your heating equipment, automation presence will allow you to achieve the normal operation of coal-fired boiler.
