Heating equipment running on liquid fuel is now becoming more and more popular. Of course, the price of the same diesel engine is not always what we would like to see it. It is for this simple reason that it is preferable for residents of multi-storey buildings to use natural gas as fuel. But for the private sector, often the only reasonable way out is to use diesel heating boilers. Fuel consumption, reviews and equipment specifications - that's what we'll talk about.

General information

It is not necessary to say once again that from an economic point of view, it is more profitable to heat a room with natural gas. But often there is no way to connect to the gas pipeline. In this case, many pay attention to electric boilers. In maintenance and operation theysimpler, but the cost of electricity makes you think about this. So, if the two options described above disappear, you should pay attention to liquid fuel boilers, in our case we are talking about diesel ones.

Such equipment is very efficient, since there is no need to pay big money for fuel. Why? You will learn this a little later. Let's talk in more detail about what diesel heating boilers are. Fuel consumption, reviews and specifications generally vary by model, so we'll take a look at a few popular manufacturers and talk about making the right choice.

Design and equipment features

As they say, everything ingenious is simple. This statement fits perfectly in our case. A boiler operating on diesel fuel is much simpler than a gas boiler and much more reliable than an electric one. In particular, because it is non-volatile, although this does not apply to all models.

The device consists of a diesel burner, a fuel filter, a pump, as well as a control panel and a pair of sensors (pressure gauge, carrier temperature sensor). The essence of the operation of such equipment is that the fuel is supplied by a pump to the combustion chamber (to the burner), where it is mixed with air. Then spraying with a fan and ignition is carried out. The resulting gases are discharged into the chimney or coaxial pipe. Here, in fact, the whole device and the principle of operation.

It would be quite logical to pay attention to how much fuel the boiler consumes. Its economic efficiency will depend on it. In general, it is customary to calculate diesel consumption as follows: kW / 10. The resulting value will indicate how much our boiler consumes diesel fuel per hour. Let's say if its power is 10 kW, then this is 1 kg of diesel, if 100, then, respectively, 10.

It is extremely important to pay attention to consumer reviews as well. The fact is that not all diesel heating boilers, the prices of which are not too high, are of high quality. So, reviews indicate that it is better to buy models with a replaceable burner. This will allow you to change the type of fuel from liquid to gas and vice versa. In the case of a built-in burner, the boiler will cost less and weigh an order of magnitude less.

How to choose a diesel heating boiler?

We'll talk about hardware specs a bit later, but for now, it's worth considering the choice a bit. The fact is that at present the manufacturer offers a large selection, and it is very easy for a beginner to make a mistake. In this case, a lot of money will be spent, but the benefit from this will be minimal. The first step is to look at the material of the heat exchanger. Today they are made either of steel or cast iron. The latter are durable and heavy, while the former are economical and light in weight. In general, a cast-iron version is suitable for a private house, especially if you take into account that such boilers in most casesfloor standing.

Single circuit or double circuit?

It is easy to guess that diesel boilers for home heating, just like gas boilers, can have one or two circuits. In the first case, the carrier is heated exclusively for space heating. Therefore, you will not have hot water, although you can provide a storage tank or something like that.

Double-circuit diesel heating boilers, the prices of which, although somewhat higher, are more preferable. But there are exceptions when, say, the load on the heating system is too high. In this case, you shouldn't worry too much. Install a single-circuit boiler and boiler. Thus, the problem with heating and hot water supply will be completely solved.

Some specifications

It is not so hard to guess that the cost of equipment increases with the improvement of operational and technical characteristics. In particular, power must be taken into account. Usually 1 kW is enough to heat a room of 10 square meters. Therefore, if you have a house of 100 square meters, then you need to buy a 10 kW boiler, such equipment will consume about 1 kilogram of diesel per hour.

As for the weight, this parameter is not so important in most cases. Almost all models are placed on the floor. True, it is worth looking at the dimensions, since sometimes there is no place to install a wide or, conversely, a high boiler. If we talk about the ratiopower / weight, then it is difficult to find any regularity. Much depends on the manufacturer and the materials used during assembly. So, boilers for 10-20 kW weigh about 100-160 kg, 25-30 kW - 170-200 kg and so on.

How to choose a manufacturer?

Another important point is the manufacturer. The fact is that there is high-quality equipment, but there is not too much. So, at first glance it is quite difficult to understand what exactly you are dealing with. In most cases, you need to look at the reputation of the company. Let's say the Kiturami diesel heating boiler, regardless of model, is in good demand. At the same time, the number of positive reviews reaches 95%. This indicates that this company produces quality products. The same applies to the Buderus company from Germany, which supplies Logano diesel boilers to our market. Although they have a high cost, they are distinguished by a long service life, high reliability and efficiency. In general, it makes sense to take a closer look at the domestic manufacturer, as our companies make very high-quality equipment. At the same time, the price for it is significantly lower than European models.

Service in brief

Periodic cleaning of the boiler is essential. The fact is that in the process of combustion of oil, diesel fuel, etc. fuel, a sufficiently large amount of soot and ash is formed. All this settles on the walls of the chamber, thereby deteriorating performance. Approximately 2 mm ash layer increases fuel consumption by 5-10%. Extremely importantperiodically clean the burner from carbon deposits. The frequency of such events must be determined depending on the quality of the fuel. The cleaner it is, the slower the formation of soot on the burner head. In any case, before the start of the heating season, it is advisable to entrust a specialist to perform preventive work. So you protect yourself from an unexpected failure of the boiler in severe frosts. In addition, diesel double-circuit heating boilers incorporate a large number of sensors and electronics.

Conclusion

So we talked about what diesel heating boilers are. Fuel consumption, consumer reviews, as well as some of the technical specifications discussed in this article will help you make the right choice. In any case, you should take care in advance about where you will take fuel for the boiler. If there are machine-building plants nearby, where oil is used as a lubricant, and a large amount of mining is simply poured out, then it is possible to agree on very favorable terms for both parties.

Most models have a fairly high efficiency, about 95%. This suggests that almost all of the combustible fuel will go into heat in the house. But diesel boilers also have their drawbacks. The main one is that the quality of fuel is not always high. During the supply of fuel to the burner, the filter quickly becomes clogged, and it has to be changed. Unlike natural gas, a diesel or oil leak is not fatal, which is no doubt very important. Buthere the joints can leak, so you need to constantly watch them and, if necessary, tighten the nut.
