Oil-fired heating equipment 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-story buildings are preferable 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 technical specifications of the equipment - this is what will be discussed.
general information
It is not worthwhile to say once again that from an economic point of view it is more profitable to heat a room using 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, they are simpler, 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.
Such equipment is very effective, since there is no need to pay a lot of money for fuel. Why? You will find out later. Let's talk in more detail about what diesel heating boilers are. Fuel consumption, reviews and specifications as a whole depend on the model, so we will look at several popular manufacturers and talk about the right choice.
Device and equipment features
As they say, all ingenious is simple. This statement fits perfectly with our case. The diesel-fired boiler is much simpler than a gas boiler and significantly 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 fuel is pumped into the combustion chamber (to the burner), where it is mixed with air. Then spraying with a fan and ignition are carried out. The resulting gases are led off to a chimney or coaxial pipe. Here, in fact, the whole device and the principle of operation.
Diesel heating boilers: fuel consumption, reviews
It would be logical to pay attention to how much fuel the boiler consumes. Its economic efficiency will depend on this. In general, it is customary to calculate diesel consumption as follows: kW / 10. The obtained value will indicate how much our boiler consumes diesel fuel 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 consumer reviews. 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 heating boiler for diesel fuel?
A little later we will talk about the technical characteristics of the equipment, but now it’s worth a little to consider the issue of choice. The fact is that currently the manufacturer offers a large selection, and it is very easy for a newcomer to make a mistake. In this case, a lot of money will be spent, but the sense of this will be minimal. The first step is to take a look at the heat exchanger material. Today they are made either steel or cast iron. The latter are distinguished by their durability and high weight, and the first by their economy and light weight. In general, a cast-iron version is suitable for a private house, especially if we take into account that such boilers are in most cases floor-standing.
Single or double circuit?
It is easy to guess that diesel boilers for heating a house, just like gas ones, can have one or two circuits. In the first case, the media 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, 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, do not worry too much. Install a single-circuit boiler and boiler. Thus, the problem with heating and hot water supply will be completely solved.
Some technical specifications
It is not so difficult 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 measuring 10 square meters. Therefore, if you have a house of 100 squares, then you need to buy a 10 kW boiler, such equipment will consume about 1 kilogram of diesel per hour.
As for weight, this parameter is in most cases not so important. Almost all models are placed on the floor. True, it is worth looking at the dimensions, as sometimes there is no room for installing a wide or, conversely, high boiler. If we talk about the power / weight ratio, then it’s hard 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 quality equipment, but not too much. So, at first glance it’s quite difficult to understand what exactly you are dealing with. In most cases, you need to look at the fame of the company. Let's say a Kiturami diesel heating boiler, regardless of model, is in good demand. At the same time, the number of positive reviews reaches 95%. This suggests that this company produces high-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 cost-effectiveness. In general, it makes sense to look at the domestic manufacturer, as our companies make very high-quality equipment. At the same time, its price is significantly lower than European models.
Briefly about service
Periodic cleaning of the boiler is essential. The fact is that in the process of burning oil, diesel fuel, etc. a sufficiently large amount of soot and ash is formed in the fuel. All this settles on the walls of the chamber, thereby impairing performance. An approximately 2 mm layer of ash increases fuel consumption by 5-10%. It is imperative to periodically clean the burner. The regularity 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 divider. In any case, before the start of the heating season, it is advisable to entrust a specialist to carry out maintenance work. So you protect yourself from the unexpected failure of the boiler in severe frosts. In addition, diesel dual-circuit heating boilers incorporate a large number of sensors and electronics.
Conclusion
So we talked about what diesel heating boilers are. Fuel consumption, customer 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 get fuel for the boiler. If there are engineering plants nearby where oil is used as a lubricant, and a large amount of mining is simply poured, then we can agree on very favorable conditions for both parties.
Most models have a fairly high efficiency, about 95%. This suggests that almost all combustible fuel will go into the heat in the house. But diesel boilers also have their drawbacks. The main one is that the quality of the fuel is not always high. During the fuel supply to the burner, the filter is quickly clogged, and it has to be changed. Unlike natural gas, a diesel or oil leak does not result in death, which is without a doubt very important. But here the joints can leak, so you need to constantly look at them and, if necessary, tighten the nut.
