The long-burning boiler is designed to heat rooms for an impressive period without replenishing fuel. As a rule, most models of this class can work on one tab of solid fuel for more than 12 hours. This effect is achieved due to the special design of the combustion chamber.

Suppliers offer an impressive selection of these types of devices. Among the presented models there are really effective and easy-to-use devices, but there are also low-quality consumer goods. In order to acquire worthwhile heating equipment for our hard-earned money, we will figure out the rules for choosing it.

What to look for when choosing a boiler?

Due to the simply huge demand for boilers operating on the same firewood tab for more than 12 hours, manufacturers are actively replenishing the market with new models. As a result, almost every buyer raises a number of questions that are related to the choice of manufacturer, design, type of fuel.

In addition, not everyone can correctly calculate the power. In order not to encounter these problems in the store, we will deal with all the nuances in more detail.

Types of equipment by design

Three varieties of solid fuel boilers are available on the market. These include classic models, pyrolysis, as well as pellet units. The first type will be an excellent choice, both for home and for industrial or commercial use.

The advantages of such models include:

  1. Versatility. The equipment can operate on heating granules (pellets), wood, peat and coal.
  2. Multifunctionality. Classic boilers are great not only for heating the room, but also for heating water.
  3. Efficiency. The efficiency of the presented devices in most cases varies between 80-85%.This allows you to use them, both as the main source of heat, and as an additional.

Pyrolysis models are most often used to heat water. This kind of device runs on fossil fuels.

Pyrolysis boiler
The performance factor of pyrolysis boilers mainly depends on the quality of the fuel used. The best choice is briquettes, pellets, as well as brown coal

It should be noted that pyrolysis boilers quite demanding on the moisture content of fuel raw materials. If this indicator is above 25-35%, then the heating efficiency will significantly decrease.

The third variation of long burning boilers has been patented in Europe relatively recently. But in a fairly short time, such devices have won recognition among hundreds of thousands of customers.

Work pellet boilers on wood pellets. Fuel is made from compressed chips, sawdust, as well as a number of other types of waste from the woodworking industry.

The advantages of the presented species include:

  • durability - the average life of the device is more than 20 years;
  • autonomy - the device independently and fairly well maintains the temperature indicated by the owner;
  • efficiency - The efficiency of models on pellets reaches 90%.

As for the shortcomings, only one stands out - the price is high and inaccessible to many. But this minus is fully paid off by the ease of maintenance and equipment performance.

With features of work and operation solid fuel boilers will introduce an article devoted to this interesting issue.

How to calculate the power?

If you need to determine the boiler performance, it is important to consider the area, the quality of wall insulation, the type of fuel used, as well as the length of the heating circuit. Calculations can be greatly simplified.

To do this, you only need to use the following formula:

1 kW per 1 m2 premises.

At the same time, the height of the ceilings should not exceed 3 meters. A more convenient option would be to use when calculating a special table. Below is one of them.

Boiler powerHeating area, sq. m
15 kWup to 150
20 kWup to 200
30 kWup to 300
50 kWup to 500
70 kWup to 700

With its help, you can find out the right power in minutes. In this case, the only parameter that you will need is the area of ​​the room in cubic meters.

Type of regulator and price tag

If in your house there are constant interruptions in the electrical network, then it will be advisable to choose a boiler with a mechanical regulator. He does not need a current supply, since his principle of action is based on air circulation in a natural way.

Automation is suitable for those who do not want to bother once again and spend their time going to the boiler room. This type of regulator pumps air with a fan.

Solid fuel boiler
A reasonable choice would be to buy a heater from an authorized dealer or directly from the manufacturer. This will not only allow you to purchase goods at a reasonable price, but also get a long warranty and rely on service in the event of a breakdown of the unit

The cost of heating equipment largely depends on the material from which the device is made, brand, as well as power. It is important to understand that this kind of technology is bought for decades. Therefore, do not even look towards cheap models. Remember - an efficient boiler cannot be cheap.

Pros and cons of long burning units

First of all, the equipment presented above is notable for its efficiency. Thanks to the special design, the fuel inside the device does not burn, but smolders slowly. This allows you to significantly increase efficiency (up to 85%), as well as for a long time to heat an impressive area.

The list of advantages of boilers operating for a long time should also include the volume of the combustion chamber.The vast majority of devices can load up to 50 kg of fuel at a time. As a result, you will forget for a long time that you need to go into the boiler room and throw firewood.

Also, unlike its analogues, heating equipment of long burning can work on different types of fuel. For example, on wood, coal, peat, pellets, ordinary and pressed sawdust. Thanks to its versatility, you, as an owner, can save a tangible amount.

Appearance of a long-burning boiler
The ability to operate on different types of fuel provides an opportunity to choose the most affordable type of fuel. At the same time, the size, for example, of firewood can be very different (from sawdust to briquettes). This helps save precious square meters in the boiler room.

As for the shortcomings, there were no noticeable minuses in devices of this class. But I would like to note the high cost. On average, the price of long-burning boilers starts at 100,000 rubles or more. Yes, you can find cheaper models, but they will not be able to please their effectiveness and ease of use.

Important when solid fuel boiler installation long-term storage responsibly to the design of the heating system. After all, if you do not carefully think through everything, then you will not feel all the advantages of the above devices.

    I put Stropuv in my house, took 20 kW, along the way is not enough, I had to do more power reserve. But the more powerful, the steeper the price, and the money during construction is scarce. Our firewood is expensive, coal is also bullshit and expensive. We drown briquettes. I can’t say that I’m missing for a long time without supervision. If you download a full firebox, then just a day is enough. There is a lot of trouble around this boiler. Not very satisfied, to be honest.

  2. There is experience using a boiler from NMK. Boiler long burning model Magnum. It completely suits me - convenient, more affordable at the price in comparison with analogs. When fully loaded, it works for almost a day, almost any fuel “eats”, traction is good, it is relatively easy to clean. In general, I am 100% satisfied with the boiler, I have no complaints about it.

  3. We have a car service 300 m2, which boilers we just did not try to heat! Thank God colleagues from Tambov suggested to buy the Cauldron (Hat). We purchased a Boiler (Hat - 35) and this is really a GREAT APPARATUS. I advise everyone not to know grief!
