The importance of choosing the right boiler room for a private house can hardly be overestimated. Drawing a comparative parallel with the human body, the boiler room can be safely called the heart of the whole structure. If initially, the “heart” is useless, the functioning of the other “organs” also leaves much to be desired.
With the wrong choice of equipment, the operation of heating and water supply systems in the future becomes difficult, and to put it mildly, does not bring pleasure. When choosing a boiler room, it is necessary to work out several fundamental issues.

Instructions for installing heating gas equipment
So, the first thing you need to decide is fuel. The most common types of fuel in our country are solid fuels (wood, coal, peat, etc., up to dried manure), gas (usually natural), liquid fuels (most often diesel fuel), electricity.
It is best, of course, to use gas. It is relatively cheap, it does not need to be constantly brought to the place of consumption, its combustion products are the most environmentally friendly, little soot remains during combustion (the chimney and boiler need to be cleaned less often), etc. A significant complication is the supply of a gas pipeline to the house. The fact that some kind of “gas” pipe runs near your site does not mean at all that you can connect to it. If the connection, in principle, is possible, then you will have to communicate closely with representatives of the local gas trust, draw up a lot of documents, permits, agreements, and, of course, pay a certain amount. On average, according to our observations, the cost of gas supply fluctuates around 3-4 thousand US dollars, in time it can take up to 1-2 years.

Some misconceptions that usually arise when choosing this type of fuel. The first is the fear that there may be interruptions in the supply of gas (accidents or shutdowns). Accidents are an emergency, this happens extremely rarely, and we cannot remember at least one such case in five years of work. You, as a consumer, can be disconnected only for non-payment for the services of the local gas economy, having previously warned, with the execution of all documents necessary for the commission of such an act.
The second is the potential danger of using this type of fuel. However, the requirements for the installation of any gas-powered appliances are so high that when using high-quality equipment and services of licensed organizations, the risk is minimized. Usually, accidents associated with the use of gas (fires or explosions) occur only in case of gross violations of the rules of Gosgortekhnadzor.

For heating liquid fuel No approval from any organization is required. The main task is the timely delivery of diesel fuel. By the way, when planning the site, in this case, it is necessary to provide for the possibility of a tanker approaching the fuel tanks, and when building a house, provide a place for the tanks and the possibility of their delivery to the premises. The larger the tanks, the less frequently you fill them up. It is a misconception that diesel fuel combustion products are harmful; with a well-adjusted boiler burner, you will practically not see smoke. But still, once a year you will have to clean the chimney and the boiler itself from soot. Fuel consumption is approximately 1 liter per 10 kW of heat output. Remember that for the smooth functioning of a diesel boiler, the quality of the fuel is of great importance.

Heating electricity generally environmentally friendly. All that is required is to obtain permission from the district power authority to connect. In the case of a single-phase network, everything is very simple, in the case of a three-phase network, documents will have to be drawn up for a long time. Everyone knows the price of electricity.
By the way, private consumers will soon be given the opportunity to use the «double» tariff, i. the daily cost of electricity is different from the night (cheaper at night). This will no doubt encourage the use of multiple fuels, eg diesel during the day and electricity at night.

Heating solid fuel the cheapest, but at the same time the most problematic. It is necessary to heat the boiler more or less constantly and manually, moreover, it is more difficult to withstand temperature parameters, fuel reserves must be stored somewhere and constantly replenished. Remember that you will not be able to ensure the operation of the boiler in your absence, at night you will also have to get up from time to time and throw firewood. The frequency of laying firewood, by the way, depends on the operation of the boiler automation, if any, but more on that later. You will have to clean the boiler and chimney often. This type of fuel is suitable, in our opinion, as a spare, or in combination with other fuels, for example, with electricity.

In any case, the choice of the type of fuel is dictated by the conditions of the given area, somewhere it is cheaper to heat with gas, somewhere the only fuel is firewood. It should be noted that not only the choice of the type of fuel, but also the heating scheme depends on local characteristics. All boiler automation and pumps run on electricity, and if you have constant interruptions, then choose a scheme with natural circulation, about it a little later.
An important step towards choosing the type of fuel is the choice of heating mode. If you’re building an occasional house with inexpensive woodwork, you can use solid fuel and fire the boiler only during visits. In this case, it is necessary to provide for the possibility of draining water from water supply and sewage systems, as well as to abandon expensive finishes, otherwise constant temperature changes and the resulting condensate will seriously spoil the appearance of ceilings and walls. In the case of liquid fuel, gas and electricity, in order to save money, you can use programmable heating modes, for example, the temperature of + 5-10ºС is maintained in the house all week, by the time you arrive, the boiler heats the house up to + 20ºС or any temperature you set.

Remember that in advance and correctly chosen heating method will significantly save your money and effort.
Regardless of the type of fuel, when choosing a boiler, several general factors must be considered.
The first is how often you expect to change it. Cheap boilers do not last long, usually the firebox burns out quickly and after that the boiler can only be thrown away. The furnace is the main element of the boiler. The durability of the boiler and its efficiency depend on the quality and design of the furnace. An expensive boiler will serve you for 25-30 years, or even more, the efficiency of such boilers is about 94%.
The second is what level of automation you can afford, the price and ease of use depend very much on it. If you agree to set the temperature in the house manually by adjusting the thermal heads, then you’d better buy a good boiler with simple automation, it’s not expensive. If the convenience of controlling equipment is important to you, then you should pay attention to more expensive automation. In any case, ask the seller to tell you in detail about the proposed automation, a lot really depends on it, including safety. The remaining elements of the boiler room — pumps, expansion tanks, fittings, piping — are almost standard for all suppliers.

Pay special attention to the burner proposed for use with this boiler. The burner is perhaps the most complex device in the boiler, and the uninterrupted operation of the boiler in all modes, as well as efficiency, depend on it. On boilers operating with gaseous fuels, two types of burners are usually installed: atmospheric, where the process of mixing gas with air occurs naturally, or fan (blowing), in which mechanical mixing of gas from air under pressure takes place, and this mixture is supplied to the furnace. Both burners have their merits. The atmospheric burner is devoid of mechanical parts, so its service life, theoretically, is longer.
The blower burner is more economical and less susceptible to a drop in gas pressure in the supply gas pipeline. All boilers operating on liquid fuels are equipped with blast burners, since diesel fuel ignites and burns only in a certain, proportional mixture of air and fuel. In the case of an oil-fired boiler, the quality of the fuel is very important. The use of poor quality fuel will lead to interruptions in the operation of the boiler, its clogging with soot, and failure of the burner nozzles. Therefore, try not to save on filters and avoid low-quality diesel fuel.
When purchasing an electric boiler, which is essentially a container with Thermal Electric Heaters (heaters), pay attention to the quality of the electrical devices installed in it. Expensive boilers, as a rule, are equipped with high-quality starters with spark arresters, equipped with reliable safety automation. In cheap boilers, heating elements burn out more often, protection is worse thought out.
Solid fuel boilers, in most cases, are initially combined. In such a boiler, there are two fireboxes, one works with solid fuel, and the other with liquid or gas. Due to the fact that solid fuel is difficult to dose, carefully consider the safety equipment and automation system of the boiler you choose.
In any case, do not skimp on the boiler. Having bought good equipment, you will provide yourself with peace of mind, safety and comfort.
