If the house does not provide equipment by the central heating system, then the installation of individual heating will be required. To solve this task, a heating boiler is fit. The most important thing is to choose the right equipment correctly. About this in more detail later.

How to choose a boiler for heating at home

Key points

The heating boiler should be chosen primarily in power and type of fuel. Consider these parameters a little more. To approximately know which power of the boiler is required, then the calculation takes that for heating 10 square meters. m required power in 1 kW.

But this is an exemplary calculation. Therefore, it is recommended to obtain the results of a more accurate heat engineering calculation. To do this, you will have to enlist the help of engineers and designers. The calculation produced by them, in particular, takes into account such parameters:

• wall thickness, material from which they are made, their size,
• as well as the number of windows (through the windows there are large heat loss).

In addition, the presence in the room of warm floors, a fireplace and the general purpose of the premises under consideration is taken into account. Boilers today can work on a wide variety of materials: electricity gas, diesel fuel, wood, pellets, coke, coal, etc.

Boilers generally made from steel and cast iron. But the manufacture of the material - is not the only criteria by which to classify boilers. For example, they are also distinguished by the method of installation. In this sense, they can be wall and floor. In addition, the equipment may be volatile and non-volatile.

If you share a similar installation in the number of circuits, they are one- and two-planimetric. It should be noted also that the waste substances are removed from the heating boilers for home and in different ways. Thus thrust can be natural and forced.

types of equipment

Types of boilers today a few. In most cases, they are separated by the method of installation and energy source.

gas installations. No boilers have not found such wide application as gas. Such popularity is mainly due to the low cost of fuel, i.e. gas. In addition, the impact on this widespread gas lines. All gas-fired boilers by location divided into floor and wall.

For floor heating boilers for private homes is required to select and equip somewhere in a separate boiler room. And it should be done in compliance with all regulations and requirements. The boiler will not operate without the heat exchanger, it is the main component of the work. It is mostly made of steel or cast iron. The simplest and cheapest option is to install floor, equipped with inflatable burners. More complex are considered boilers with atmospheric burners. This option is more expensive, but it has a higher efficiency. The design of wall-hung boilers for home heating, as a rule, there is an expansion tank and circulation pump. This allows him to occupy less space.

The number of loops in such plants can likewise be different. So, as mentioned above, there are single and double-circuit boilers for home heating. Incidentally, the last option settings not only heats room, but heats the water. And their sizes are generally fairly compact, making them well suited as a private home heating. This also contributes to ease of installation and ease of maintenance. As for the single-loop, they are only able to heat the heat transfer fluid, which is used for heating homes.

Liquid fuel boilers. Diesel boilers are most popular from the variety of this equipment. In their design, there is a removable burner, changing which it is possible to change the type of fuel used. From the mandatory additional equipment for their successful operation requires the installation of a ventilation system and chimney.

Fuel can be kept directly indoor boiler room. But at the same time it is required to use a special container. In addition, it is necessary to comply with the basic rules of fire safety. According to these requirements, plastic tanks must be installed in a metal pallet, which, when the leakage appears, will not allow fuel to break through the floor. Steel containers equipped with tightness control is allowed to be installed without pallets. If there is no possibility to put such a container in the house (for example, if the boiler is placed in the utility room) then in this case it will have to burrow it into the soil.

Liquid fuel plants require a power supply for its normal operation. Electricity is needed to operate the pump that liquid fuel is supplied from the storage location in the boiler. Among other things, you need to warm the feed pipe carefully. The fact is that under negative temperatures, the fuel becomes more viscous. Moreover, the more viscous it becomes, it requires greater malno power. Therefore, there is a possibility that at very low temperatures, the pipeline without insulation will become impassable, i.e. Purcharge.

Electric heating boiler for home. First of all, it is worth saying that the permission to install similar equipment is not required. In addition, the temperature control system in such installations should be noted. Despite these advantages, such boilers are far from always use as the main source of heat. More often they are installed as spare, and the main fuel boiler is installed. In addition, it is installed in places where gas has not been carried out.

With the help of the boiler you can drop the house with an area of \u200b\u200bup to 270 square meters. m. If the building has a large area, then more powerful equipment will be required, which will affect the cost. Obviously, the ventilation system is not required for such boilers. The need for permission to install such equipment depends primarily on its power. If briefly, all boilers with a power of more than 10 kW are permission required. You do not need to receive permission to get on low-power settings.

Of the advantages of such aggregates, it is also worth noting the lack of need to erect additional facilities. What is required is a separate wiring. The fact is that not all installations work from a single-phase power grid. For the work of many heating boilers for a private house, a three-phase power grid is required. Moreover, this network should be protected by a protective shutdown machine, which will avoid trouble in the event of a breakdown or short circuit. To select a suitable automaton, it is often used by a special table in which already calculated values \u200b\u200bare indicated depending on the boiler power.

By type of hot water, there are two types of electrocotors - electrode and shadow. The first option is a container with electrodes. Their work is based on the principle of flowing water heater. The efficiency of this type of electrode is about 96%. In case of malfunctions, the equipment will simply automatically turn off. As for the shadow boilers, their efficiency is slightly lower, and can be from 68 to 93%. Water in such boilers is not connected with electricity. Therefore, they are considered safe. At the same time, the equipment is equipped with a system of smooth or stepped power control. In case of breakdowns of one of the ten shows, the boiler continues to work.

If the question arose what to choose, then you should know that the electrode boilers are not allowed to use for warm floors, the heating of pools. This is due to the fact that under such conditions there is a probability of a breakdown of isolation, which can lead to a damage to the current. Therefore, for heating in these cases, only shadow installations will definitely fit. For all other situations, the electrode boiler will be more suitable. In addition to the specified aggregates, there are also combined heating boilers for a private house.

What kind of fuel to choose

Living in a private house is good mainly because you yourself decide how you will give the existing rooms. Gas, firewood, pellets, electricity or liquid fuel? This question is asked almost everyone who chose a heating system. What is the cheapest? Of course, liquefied or natural gas. Therefore, if there is a gas pipeline, choose, in fact, there is no need. All gas boilers for home heating today have an automatic control system.

Installations in which firewood and coal are used as fuel are called solid fuel. Such boilers need to pay a lot of time. It is impossible to make their work fully automatic. The fact is that to maintain heat you need to periodically lay fuel. However, the installation data is good because it is optional electricity.

As already noted, boilers operating from electricity require considerable costs in the process of energy. The aggregates of this type are relatively cheap. In addition, electricity is the most eco-friendly fuel type. The installation requires the presence of a power supply of suitable power. Such installations are often operated together with solid fuel boilers for the heating of a private house. On the one hand, it will reduce electricity costs. In addition, you will need to put fuel less often, for example, firewood, in a solid fuel boiler.

If we consider diesel fuel as an example of "filling" for boilers, it should be said that it is not such a road as electricity, but still costs remain substantial. However, it is worth considering the fact that such boilers are usually fully automated.

In addition, many models of such aggregates can work not only on diesel fuel, but also on gas. This is useful if the gas is temporarily not, but it is known that it is accurately plugged after a while. While it does not happen, a private house can be pulled off with liquid fuel. Modern boilers are assembled in such a way that, when they work, the smell of gas or noise does not appear. The smell can only feel completely close to the tank with fuel or during refueling. In general, everyone decides, what heating he wants to see in his form. But still, when choosing a boiler for heating at home, do not neglect the tips, which are given by experts. Given all this, you can easily choose for yourself the best boiler for the heating of a private house.

Selection of power aggregate

It is no secret that it is power that is the main parameter for which the heating boiler is selected. Optimally pick up power so that it allows you to drop the whole house. The calculation of this indicator necessarily takes into account the heat loss of the construction. The results of such calculations will help you choose both the boiler and the necessary heating devices.

Such a settlement in order to save is quite rare. Most often use average power values \u200b\u200bfor one or another region. To begin with, the condition is taken that for heating 1 sq.m. You need about 100 W power. In addition, edits are usually made depending on those or other features of the room. However, this method of calculation cannot be called accurate, but it is still successfully used in practice.

In our areas in winter, the thermometer is often descended to rather low temperatures. Heating should provide a normal temperature in the house even in such conditions. Therefore, this is taken into account in the calculations. Obviously, not always from the boiler requires high power. Therefore, they are equipped with a function that allows you to automatically adjust the power under the current conditions. If such an option at the boiler was not, it would be constantly turned on, then turned off.

Obviously, it negatively affects not only the heating unit, but also on the comfort of people living in the house. If the boiler has such a function, then power is automatically liquefied when the set temperature is reached. Anyway, the installation power must be at least 25 kW. Otherwise, he will not be able to heat the entire volume of water. Thus, if you have a small apartment, the boiler must have a minimum power of no more than 6 kW, the maximum should not be at least 25 kW. It is also important to the value of the volume of the expansion boiler - it should be at least 7-8 liters. These tips will help find the right answer to the question of how to choose a home heating boiler.
