Heating equipment operating on liquidfuel, is now becoming increasingly popular. Of course, the price of the same diesel is not always the same as we would like to see it. It is for this simple reason that residents of multi-storey buildings prefer to use natural gas as fuel. But for the private sector, the only reasonable solution is to use diesel boilers for heating. Fuel consumption, reviews and specifications of equipment - that's what will be discussed.
general information
It is not necessary to say once again that witheconomically, it is more profitable to heat a room with natural gas. But often there is no possibility to connect to the gas pipeline. In this case, many pay attention to electric boilers. In maintenance and operation they are simpler, but here the cost of electricity makes you think about it. So, if the above two options fall away, it is worth paying attention to liquid fuel boilers, in our case we are talking about diesel.
Such equipment is very effective, sincethere is no need to pay a lot of money for fuel. Why? This you will learn a little later. Let's talk in more detail about what diesel boilers are. The fuel consumption, reviews and specifications generally depend on the model, so we will consider several popular manufacturers and talk about the right choice.
Device and equipment features
As they say, all ingenious is simple.This statement is excellent for our case. The boiler, which operates on diesel fuel, is much simpler than gas and much more reliable than electric. In particular, because it is non-volatile, although this does not apply to all models.
The device consists of a diesel burner,fuel filter, pump, as well as the control panel and a pair of sensors (pressure gauge, temperature sensor of the carrier). The essence of the work of such equipment is that the fuel is supplied by the pump to the combustion chamber (to the burner), where it mixes it with air. Further, the fan is sprayed and ignited. The forming gases are diverted into the chimney or coaxial tube. Here, actually, the whole device and the principle of operation.
Diesel heating boilers: fuel consumption, reviews
It is quite logical to draw attention to the fact,how much fuel the boiler consumes. This will determine its economic effectiveness. In general, it is customary to calculate the consumption of diesel as follows: kW / 10. The value obtained will indicate how much our boiler consumes diesel per hour. Say, if its power is 10 kW, then it is 1 kg of diesel, if 100, then, respectively, 10.
It is extremely important to pay attention to the feedbackconsumers. The fact is that not all diesel heating boilers, the prices for which are not too high, are of high quality. So, the testimonies 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 an integrated burner, the boiler will cost less, and weigh an order of magnitude less.
How to choose a heating boiler for diesel fuel?
A little bit later we will talk about technicalThe characteristics of the equipment, but now it is worth considering the matter of choice a little. The fact is that at present the manufacturer offers a great choice, and it is very easy for a beginner to make a mistake. In this case, a lot of money will be spent, but the sense of it will be minimal. The first thing is to look at the heat exchanger material. Today they are made either steel or cast iron. The latter are longevity and heavy weight, while the former are economical and light in weight. In general, for a private house is suitable cast-iron option, especially if you take into account that such boilers are mostly floor-standing.
Single-circuit or dual-circuit?
It is easy to guess that diesel boilers forHeating the house, just like gas, can have one or two circuits. In the first case, the carrier is heated exclusively for heating the room. Therefore, you will have no DHW, although you can provide a storage tank or something like that.
Double-circuit diesel heating boilers, prices forwhich, although somewhat higher, are more preferable. But there are exceptions, when, say, the load on the heating system is too high. In this case, do not worry too much. Install a single-circuit boiler and boiler. Thus, the problem with heating and hot water supply will be solved completely.
Some technical characteristics
It is not so difficult to guess that the costequipment increases with the improvement of operational and technical characteristics. In particular, one must take into account the power. Usually 1 kW is enough to heat a room measuring 10 square meters. Therefore, if you have a house of 100 squares, then you need to buy a boiler for 10 kW, this equipment will consume about 1 kilogram of diesel per hour.
As for weight, this parameter inmost cases are not so important. Almost all models are placed on the floor. True, it is worth looking at the dimensions, because sometimes there is no place to install a wide or, conversely, a high boiler. If we talk on the power / weight ratio, then it is difficult to find any regularity. Much depends on the manufacturer and materials used during the assembly. So, boilers for 10-20 kW weigh about 100-160 kg, 25-30 kW - 170-200 kg and so on.
How to determine the manufacturer?
Another important point is the manufacturer.The fact is that there is quality equipment, and there is not too much. So, at first glance, it is difficult to understand what exactly you are dealing with. In most cases it is necessary to look at the company's fame. For example, Kiturami diesel 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 high-quality products. The same applies to the company Buderus from Germany, which delivers to our market diesel boilers "Logano". Although they have a high cost, they are distinguished by a long resource of work, high reliability and economy. In general, it makes sense to 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.
Briefly about maintenance
Periodic cleaning of the boiler is simply necessary.The fact is that in the process of burning oil, diesel fuel, etc. a rather large amount of soot and ash is formed. All this settles on the walls of the chamber, thereby worsening the performance characteristics. Approximately 2 mm ash layer increases fuel consumption by 5-10%. It is extremely important to periodically clean the burner of the burner. The regularity of such measures must be determined depending on the quality of the fuel. The cleaner it is, the slower the soot builds up on the burner divider. In any case, before the start of the heating season, it is advisable to entrust the specialist to perform preventive work. So you will protect yourself from unforeseen refusal of the boiler in severe frosts. In addition, diesel dual-circuit heating boilers have a large number of sensors and electronics.
Conclusion
Here we are and talked about what isdiesel heating boilers. Fuel consumption, consumer reviews, and some of the technical characteristics discussed in this article will help you make the right choice. In any case, it is worthwhile in advance to take care of 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, then it is possible to agree on very favorable terms for both parties.
Most models have a fairly high efficiency,about 95%. This indicates that almost all the combustible fuel will go to the heat in the house. But there are diesel boilers and their minuses. The main one is that the quality of fuel is not always high. During the fuel supply to the burner, the filter quickly clogs, and it must be changed. Unlike natural gas, the leakage of diesel or oil does not lead to a lethal outcome, which is undoubtedly very important. But the joints can cause leaks, so you need to constantly look after them and, if necessary, tighten the nut.
