The technical condition of heating systems and water supply in urban apartment buildings, unfortunately, leaves much to be desired. What to speak of private homes in the villages. In this regard, the most pressing issue is for Autonomous, independent communications obschedomovyh water heating and home heating.
The device, which is designed for these purposes is very costly, so it is a choice – a complex event that requires a special approach and knowledge.
The bases of the boiler ↑
There are a few rules that will help to make the right choice of boiler for a private home.
For example, you should know what type of fuel is most suitable for a particular location. House located in the garden area it is best to heat with wood. If near the area there are thermal springs, it is self-evident that the best type of coolant for the boiler will become water. The existence of gas pipelines near the location of the home is automatically cut off all fuels except gas, which is burning, is converted into heat.
It is very important when choosing the heating appliance to take into account the heat loss of the house, associated with an external heater. Another important parameter is the number of required hot water. Taking into account all these variables, it is possible to calculate the required capacity of the boiler, and only then go shopping.
The types of heating boilers ↑
A large assortment of heating devices sometimes put the consumer in a dead end. Very hard to choose perfect option among such a variety.
The most popular types of heaters for private homes are:
- gas boilers;
- electric heating devices;
- solid units.
Consider in more detail each of these options and highlight their positive and negative sides.
Gas boiler ↑
This is the most common type of heating appliance that attracts the consumer not only its value, but also the availability of used fuel. These devices are divided into two types:
- condensing heating appliances. Their difference lies in the fact that in addition to thermal energy using the heat from steam. This approach helps to save gas consumption, which is very important in the light of constantly increasing tariffs for natural gas;
- convection heating devices. Heating the coolant comes at the expense of energy obtained by the combustion of fuel. They have open combustion chambers and are due to natural draft.
It is very important when choosing the heating appliance to pay attention to the heat exchanger. It’s a special tank, made of metal, which heats the coolant. If it is steel, it is likely the service life of such products is short lived. Iron tank is more resistant to temperature changes, is practically not subject to rust, and their lifetime is 60 years.
Heating devices that heat medium which is a natural pull, very easy to operate and cost-efficient. If the calculation of the required power performed correctly, can efficiently heat a room of any size.
Electric boiler ↑
This type of heating appliance is the most expensive to maintain, but the high cost of fully compensated by efficiency. Depending on the capacity of the electric heating devices are: single phase, three phase and multi-stage. The third option makes the most efficient use of energy and to avoid problems associated with sudden power surges.
Depending on the principle of electric boilers for heating of private houses are:
- electrode;
- working from the electric heating elements;
- induction.
Solid fuel boiler ↑
This type of equipment is the most labor-intensive to maintain. It can be used as main, additional or auxiliary heater. In the case of the auxiliary boiler, it heats and warms the coolant before start electric or gas boiler for private house heating, which is designed to maintain the desired temperature of the air in the room.
By far the most popular models of solid fuel boilers are:
- The pyrolysis unit. It is based on the generation and further combustion of the pyrolysis gas, which is released due to combustion of solid fuel and with a minimum of oxygen. Pyrolysis coppers of long burning equipped with a special gas regulators that regulate the supply of oxygen enough for combustion quantity. After the flare-up volume of oxygen is sharply reduced, that forces solid fuels smolder, and configures the unit to operating mode. It should be noted that heating devices of this type operate on virtually any kind of solid fuel: wood, coal or pellets.
- Pellet boiler. Operated in pressure-treated wood – pilleth. Few models of pellet boilers for heating of private houses are equipped with a screw, which, after some configuration automatically delivers the right amount of solid fuel in the furnace. Type of ignition – automatic. Also, the combustion duration is affected by the volume of the hopper.
- Solid fuel boiler long burning. The design type of the heating appliance, the fuel can be firewood, sawdust, coal or a mixture of peat and wood. A special feature of this type of heating devices was the improvement of the bunker. Combustion of fuel occurs from top to bottom and is accompanied by a slow decay. Due to this, the combustion duration may increase to one day.
Oil boilers ↑
This type of heating has gained its popularity due to high efficiency and full autonomy. The only drawback that discourages some buyers is the high cost of maintenance and fuel price. But in spite of this, this type of heating appliances are widely used in homes that are technically impossible to connect to the systems of gas supply.
The principle of operation of this boiler based on the combustion of liquid fuels. It is under pressure is sprayed into the combustion chamber where mixing with air is ignited. Traditionally, liquid fuel boilers equipped with automatic control, and depending on the type of fuel used divided into diesel and oil.
Classification by functionality ↑
Typically, the heating devices for private homes are divided into:
- Single-circuit heating boilers. They are intended only for heating, as it has only one heat exchanger. In the case where the boiler has a storage tank and the heat exchanger, it becomes possible to provide not only a warm space and hot water.
- Dual. Their distinctive feature is the compactness. As a rule, Combi boiler mounted in small houses. Point distribution of hot water should be placed near the boiler.
What is a wall and floor system ↑
Heating of a private house can be wall or floor.
Wall units are attractive due take up much less space, when mounted on the wall, under the boiler is a sufficient amount of free space that you can use at will. It is important to note that wall-mounted boilers are light. Them simple to transport and mount on the wall.
The disadvantages of wall heating devices include a small useful volume of the tank, as well as some features of the manufacture of the heat exchanger. They are usually, made from copper, which has the worst (compared to iron) the thermodynamic indicators.
Types of outdoor heating devices are very bulky and heavy. They take up a lot of space and they are difficult to transport and install. Heat exchangers of boilers of this type is made from cast iron that will remove any restrictions concerning the volume of the tank.
The choice of the manufacturer ↑
Today the market of heating devices is replenished with domestic products. The quality of boilers is not inferior to analogues of foreign companies, while the costs of purchase and maintenance cost much cheaper.
With regard to foreign companies, then there is the clear leader manufacturers of boilers, remains of the German mark Bosh.
Conclusion ↑
It is important to remember that regardless of the manufacturer and the type of the selected boiler, it is necessary to follow the current state. Any, even the smallest fault can cause a big tragedy, so any heating devices must undergo regular preventive examinations and kept in perfect condition.
