Heating of private houses is causing more and more interest among the inhabitants of the private sector not only in villages, but even in large cities. The price of energy is constantly rising, and the economic crisis is forcing homeowners to think about the effectiveness of heating their own facilities.
This article is intended for those who want to understand the most diverse ways of heating residential buildings and when choosing their own system, consider the pros and cons of each of them.
How to connect a solid fuel boiler
Tying a solid fuel heating boiler, the scheme of which is quite complicated for a beginner, involves familiarizing yourself with an overview of the energy carriers that are present on the market and the heating systems that work on them.
- Natural gas, one of the most common energy carriers in the gasified part of the country. The advantages include the ability to create an automatic heating system that would not need human participation;
- Electricity, an equally common heating method, but requires a fairly powerful input of power to the house, preferably a three-phase one. And this condition is not always ensured especially in rural areas;
- Coal, firewood and other fuel for solid fuel boilers, requires a fairly frequent human presence and is difficult to automate. Heating automation is quite expensive;
- The sun, wind, geothermal sources today are often exotic sources of energy and are available only to wealthy segments of the population.
If we talk about the methods of circulation of the coolant, then there are only two of them:
- Forced circulation;
- Natural circulation.
How to connect a solid fuel boiler to the heating system? Each of these methods has its advantages and disadvantages. To choose one of them, you need to carefully weigh the possibilities of their use in certain situations. Let's take a closer look at each of them.
Scheme of the system with natural circulation
The easiest way to build heating methods, the boiler piping is minimal. The advantages include:
- Work without the use of electric pumps. That is, even with a complete power outage, the system will heat the room.
- Low cost of equipment.
- Easy setup and maintenance.
The disadvantages of installing solid fuel boilers include:
- Low efficiency and, accordingly, fuel overrun.
- Inability to control the combustion and circulation process, heating works in manual control mode.
System circuit with forced circulation
Pumps are used to pump the coolant through the pipes. Tying such a system is much more complicated and expensive. The advantages of the system include:
- High efficiency;
- Adjustment of the temperature of the coolant;
- The possibility of using automation;
- The possibility of using emergency and fire-fighting systems.
The disadvantages of such systems include:
- The inability to work without electricity;
- The high cost of equipment.
Attention: emergency shutdown of electricity can lead to overheating of the equipment and its failure. Therefore, a backup power source is required.
There are not so many types of coolants. The most common is plain water. But when heated, scale forms in the pipes, and if it is drained from time to time, then rust.
More expensive is the use of natural or mineral oil, such as spindle oil, as a coolant. But this method is quite expensive, although more effective.
How to make strapping cheaper
How to tie a solid fuel boiler with a closed system? The boiler piping is a set of all kinds of elements that ensure reliable and uninterrupted operation of the boiler and delivery of the coolant in a given quantity and the required temperature to the radiators in the rooms.
As a rule, the boiler piping is much cheaper than the boiler itself, and more importantly, it is the comfortable conditions that it creates in the cold season. But when drawing up a scheme for tying solid fuel boilers, there is a temptation to save not on the boiler, but on its tying, but you should understand the following:
- Buying cheaper strapping elements leads to a drop in reliability, especially if these elements are made in China;
- Simpler strapping methods reduce system performance;
- In the event of an emergency or extreme situation, equipment may be destroyed.
When connecting a solid fuel boiler to the heating system, several elements can be attributed to the strapping elements. Depending on the method of organizing the boiler equipment, the configuration of the piping may differ. But as a rule, certain elements of the binding are required. These include:
- One or more pumps depending on the complexity of the system;
- Expansion tank;
- Three-way valve;
- Security group;
- Filters
- Drain and ball valves.
How to tie a solid fuel heating boiler, what should be the scheme? Elements such as expansion tank and pump will be present in any circuit. But some elements are necessary for more convenient start-up and maintenance of equipment, so their presence in the system is not necessary, but desirable. One of the optional elements of the system is a heat accumulator. Let's look at its principle of action and purpose.
How to connect two boilers
The heating scheme of a private house with a solid fuel boiler requires a backup device. In case of failure of the main boiler or its transfer to routine maintenance, it is desirable that the backup boiler is automatically switched on. The corresponding piping of such a boiler should automatically disconnect the heating equipment from the main boiler and connect the backup one.
Important: The layout of the binding of a solid fuel boiler with a circulation pump does not mean that there is a need to install a backup boiler of the same power as the main one, since its task is to keep the system in working condition until the main boiler starts up. Typically, such equipment is installed in rooms where special attention is paid to uninterrupted heat supply.
Harnessing a solid fuel boiler with a heat accumulator
How to connect a solid fuel heating boiler with your own hands? The heat accumulator is usually called the additional capacity for the coolant in which it can be stored for a long time and used to heat the room. It is an insulated thermos that can accumulate one ton or more of coolant. The layout of the solid fuel boiler strapping using a heat accumulator is one of the most complex.
The connection scheme of the solid fuel boiler to the heating system is such that the system automatically selects the direction of movement of the hot coolant. There can be two options:
- In convectors located in the premises;
- In the heat accumulator.
The connection diagram of the solid fuel boiler is such that at the beginning of operation the heat accumulator heats up to a predetermined temperature, and only then switches to heating the rooms directly.
The advantages of installing a solid fuel boiler in a private house include the following points:
- High efficiency of heat transfer from the boiler to heated rooms;
- A long time to heat the room, even when the boiler is off;
- The ability to create a system for supplying premises with hot water without additional heating devices.
The disadvantages of tying a solid fuel heating boiler in a private house are:
- Large financial costs for the organization of the strapping of the boiler with a heat accumulator;
- Mandatory availability of electricity to control equipment.
Tying the boiler with a heat accumulator
The layout of the solid fuel boiler with a heat accumulator involves a three-way. With its help, two heating circuits are created. The first between the boiler and the heat accumulator and the second between the heat accumulator and the heating devices of the house. A three-way valve controls the on and off of these circuits to efficiently heat the room. The layout of a solid fuel boiler with a battery tank is not complicated.
Buffer Harness
The layout of the binding of a solid fuel boiler with a buffer capacity: one of the mandatory elements of the binding of the heating system, the purpose of which; maintain a constant pressure in the heating system with a changing temperature of the coolant. The binding of a solid fuel boiler with a buffer capacity is usually calculated in the amount of ten percent of the total coolant volume.
Connection of boilers with various energy sources
Since the cost of energy and their availability is constantly changing, many homeowners have organized boiler houses with several boiler power sources. The layout of the binding of a solid fuel heating boiler with a heat accumulator usually assumes the presence of gas and electric boilers, which allows them to be used at the most suitable time.
Features of connecting emergency systems
These elements of boiler equipment are designed to operate in emergency conditions, such as power failure in a boiler room with a solid fuel boiler working, which cannot be extinguished instantly. Such systems will allow the coolant to be cooled until electricity appears. Or automatically turn on the backup power source, and the system continues to work as usual.
