Choosing a boiler
Before leaving forboiler heating, you must decide for yourself a few questions.First, you need to determine the type of fuel, and secondly, to calculate the thermal power needed to maintain a comfortable temperature indoors.
main types of fuel, which employ modern individual heating boilers - a diesel fuel, electricity, gas, wood and coal.
Just great if next to your house passes a gas pipe.Heating for natural gas is currently considered the cheapest.If the gas supply in your area is still in the plans, then you should definitely buy a combi boiler working on alternative kinds of fuel, such as gas and electricity, and gas and diesel fuel, then go to only gas heating.But water liquid fuel heating boilers, operating on diesel fuel, should be considered only if the house is located at a distance from any other communications.Serve them is difficult, they require a separate room for their accommodation, as well as a special place to store a sufficient amount of diesel fuel that has, I must say, very specific smell.
basic requirements that the consumer makes the heating equipment - it's effectiveness, efficiency and reliability.Try to understand how to choose a boiler that meets all of these criteria.
How to choose an efficient boiler heating
To boiler heating easy to maintain a comfortable microclimate in the house, it is necessary to calculate its power.To do this, you need to evaluate the heat loss of your home.
If the construction is not insulated, and the windows in her old-fashioned, then for every cubic meter of space heating take about 40 watts of power.Well insulated housing saves 20 watts, that is, in this case, based on each cubic meter should be planned 20 watts of power.In the presence of other factors that increase heat loss, such as the walls of sand-lime brick, or the location of the house in the climatic region with very low winter temperatures, increase the amount of power needed to heat one cubic meter of space, up to 50 watts.
Do not buy a boiler in the technical specifications which contains the amount of power produced.As a rule, all the manufacturers in the documents prescribed maximum power and not the fact that the equipment will actually give it during operation.To be sure, that bought the boiler will meet your expectations, increase the value of the power produced is still 20-25 percent.Little or sudden gas pressure drop in the system, or not to be missed voltage circuit.Besides the continuous functioning at full capacity will significantly reduce the life of the boiler.
If you set out to choose a really effective heating boiler, be sure to specify the volume of its furnace.If it is too large, the burning fuel will be cooled by the constant influx of air, and if too small, the fuel will not issue the maximum amount of heat due to lack of oxygen, which is essential for normal combustion.
How to choose an economical heating boiler
natural desire of every consumer - to reduce heating costs.Still, the winter season we have quite a long way and a wrong selection of the type of fuel and the boiler can be a severe blow to the pocket.For economical fuel consumption corresponds to a heat exchanger transfers the heat to the coolant, so when buying this element of the boiler should be given due attention.
The first is to ask what thickness of steel heat exchanger is made.The thicker walls and above its thermal conductivity, the greater the amount of heat it can pass into the water.
The market offers boilers with heat exchangers two types of iron and steel.Cast considered to be more resistant to corrosion and durable, but they weigh more, which makes it difficult of transportation, and very fragile.It is often made of cast iron heat exchangers damaged during loading or unloading.
boilers with steel combustion chamber are light and resistant to damage, but if misused, they quickly fail.For such equipment is essential correctness of the heating system.
If the material from which the heat is produced, you can still find in the data sheet, here the thickness of the steel, the situation is somewhat more complicated.Learn it can be, by weight of the boiler.Heat exchanger with walls 3 mm and a power of 10 kW can easily weigh 70 kg, namely such boilers are considered most effective.Reducing the wall at least 1 mm reduces the weight of 15-20 kg, so do not buy pots, weighing less than 40-45 kg, about efficiency in this case is not out of the question.
How to choose a reliable heating boiler
reliability of the boiler, in the understanding of most people - is its protection against fire.If we talk about gas equipment, in order to prevent a gas leak, threatening not only the fire, but also a serious explosion, they must be provided with proper burner design.Another element that must be equipped with gas equipment, - a system of automatic shut-off at the termination of the gas supply.Probably no need to explain, what is dangerous lack thereof.
Thus, the main selection criteria are working for all kinds of boilers, we have reviewed.Now you need to get acquainted with the advantages and disadvantages of each specific type of equipment.
Types of boilers
the boiler on the market so much that not only "dazzled", but generally lost among their diversity.Gas, electric, combined, atmospheric, with some even in two versions: wall and floor - my head is spinning.Let us calmly sort out their advantages and disadvantages.Let's start with the most common.
main advantage of gas boiler - it is his efficiency.Also worth noting is its ease of installation and ease of maintenance.With its compact size, they are characterized by high efficiency.To display the products of combustion is small enough ventilation shaft.
The most important drawback of the gas equipment is the need to obtain special permits state authorities to install it.Provided it after a thorough verification of compliance with the following rules:
- for outdoor structures necessary to have ventilated the boiler room with a separate entrance;
- for hinged necessary that withstand a certain distance from the ceiling, floor and walls;
- location for the boiler must be chosen in accordance with the rules of fire safety.
The design of the burner gas-fired boilers are divided into atmospheric and supercharged.Atmospheric operate almost silently and are more reliable supercharged more efficient by equipping fan burners that allow to raise efficiency of up to 90-95%.However, in contrast to the atmosphere, they are much more expensive and noisy.
By way of installing distinguish floor and wall heating boilers.The functionality they have almost the same, but the size and power can vary considerably.If you choose the boiler for a large cottage, the wall-mounted boiler heating is not even worth considering.They go only for heating small rooms up to 320 square meters.Of course, you can set some of these structures, but what if there is an opportunity to buy more powerful gas-fired heating boilers?Wall-mounted boilers are usually small and neat.They can hang in the kitchen, they fit into the interior, not particularly caught my eye.Many of them even have a very high efficiency, especially those models that are equipped with a circulating pump.
With heating boilers can solve the problem of hot water in a country house.Floor models are usually equipped with tanks, heaters, hot water which is carried out by a heat exchanger connected to the heating circuit, and the wall dvuhonturnye boilers are equipped with built-in heat exchanger DHW flow type.
main advantages that each electrical heating boiler is the absence of combustion, which is why there is no need of special equipment and chimneys space to accommodate them.This "miniboiler" has a compact size.Such boilers are easy to install and silent, but there are also significant drawbacks:
- Russian electric lines are not always able to give the power needed for the normal functioning of the electrical equipment;
- power outages will need to find alternative ways of heating;
- high cost of electricity.
In our country, such boilers should be considered only as a fallback in the event of failure of the main equipment.
Fuel oil boilers
Unfortunately, except for high efficiency boilers are almost have pronounced advantages, but they have enough drawbacks:
- for storing large stocks of diesel fuel will be sure to place bulk containers, which also shouldto maintain a certain temperature.The fact is that when the temperature drops below + 5 ° C and the diesel oil thickens ceases to pass through the filters.
- Diesel fuel has a very unpleasant smell.
- burners work extremely noisy.
From the above it can be concluded that the purchase such boilers is recommended only if you can not operate the heating equipment of any other type.
Solid fuel boilers Solid fuel boilers
available in almost every region of our country, and the fuel for them differs little cost.Significant deficiencies dissuasive most consumers are the low level of efficiency and the need for frequent load of firewood, coal, peat or coke, as well as cleaning the ash, so they are not very popular.
Installation of heating boilers
Before starting the installation of the heating boiler, it is necessary to prepare a place where it will be located.For devices that emit combustion products, need training vertical ventilation shaft-chimney.It does not apply to equipment with closed combustion chamber, in this case the necessary horizontal (coaxial) chimney, bred directly on the street.
expansion tank is installed at the highest point of the system, while if the boiler is not heated, it is necessary to insulate the expander.The supply and return pipe should be laid with a slope toward the coolant flow.
Features installation of gas boilers
room to install a gas boiler heating systems must meet the following requirements:
- total area of at least 4 square meters.
- ceiling height of at least 2.5 meters.
- sure to be a window to the side of at least 30 cm.
- door width of not less than 80 cm.
to the wall, which will be located near the boiler, it is necessary to attach a special stand and mounted boilers for - mounting that do not allow the body to touchwalls.After installation, boiler in place need to perform piping, ie the connection of electrical circuits (if available), water and heating pipes in full compliance with the preparation and approval of the scheme.Before the pump be sure to place filters that prevent scale and other deposits inside the boiler and heating pipes.
Features installation of solid fuel boilers
In the room where the planned placement of solid fuel boiler, the floor must be absolutely flat.Mandatory ventilation and chimney, which is located in the main wall of the building.The overall height of the chimney grate should be more than 5 m, and its height above the roof of the serving by the rules exceed 50 cm. Chimney for solid fuel boilers necessarily equipped with a niche for cleaning soot from no less than 50 cm deep, which is covered by the door.
boiler should be installed so that it is below the level of the floor, and his furnace was provided free approach, at least one meter wide.
Features installation of electric boilers
installation of electric boilers do not pose any difficulty.The only requirements that are presented to him:
- free access;
- bottom outlet must be arranged below the radiator;
- connection is made via a residual current device.
When you install any of the boiler should be mindful of the need for strict observance of an approved scheme, otherwise you can forget about its effectiveness.
