Pros and cons simple and reliable design high efficiency easy to operate requires a chimney at least 7 meters highHow to choose a solid fuel boiler, types of boilers
Work principles
Solid fuel boiler: there is a combustion chamber where fuel is loaded. It is set on fire (automatically or manually – these are already options). A coolant flows inside the walls of the chambers, which, being heated by the energy released by the burning fuel, already carries heat through the heating system of a house or industrial premises.
• Combustion cannot go on without oxygen, i.e. the boiler needs constant air access, which is carried out through a blower in the lower part of the boiler. The combustion force also depends on the level of air supply (it is regulated by a thermostat, which for conventional models rotates manually).
• Two more important components are the chimney (the products of combustion must be removed somewhere), and solid waste is poured into the ash box from below.
Types of boilers
The most common type of solid fuel boilers is the classic: simple as a concrete pillar, and reliable as a cast-iron slab. To break – you have to try hard. When installing such a boiler, you do not need to bow to the administration and obtain permission, as, for example, with gas. And it is inexpensive, and fuel is cheap.
Pros and cons simple and reliable design low price there are both double-circuit and single-circuit low operating costs easy to maintain no problems with documentation additional areas for fuel storage are needed require regular loading of fuel and supervision carrying and loading of fuel pollutes the premises when burned, the fuel emits a characteristic odor• Even on the Russian market, they offer improved models of solid fuel boilers that can work either on solid fuel or on gas. This is achieved by installing a gas burner in the boiler. Moreover, many wood-burning boilers with electronics already come with their own block of heating elements, which are very convenient – they heat the house, for example, at night, when the firewood has already burned out and there is no one to throw new ones – everyone is sleeping. They are more expensive than classic ones, but not by much.
Long burning boilers: The main difference from the classical ones is the burning time. The efficiency of such boilers is higher (about 85-90%, while the classic models with constant reloading are only about 75%). True, you will have to pay for convenience – you will have to pay a tidy sum for “long-term” boilers. Long-burning boilers work best on coal.
Pros and cons flooded and forgotten high efficiency many models are non-volatile larger in size than classic ones are more expensive require high-quality coal or charcoalPyrolysis boilers: reach an impressive efficiency figure of 95%. The reason for this is an improved combustion process, where gases from conventional solid fuels in one chamber (they are formed with a limited supply of oxygen) are removed to another (the so-called afterburner chamber), where they burn without residue. That is, the fuel does not fly out into the pipe, but is used by almost 100%. However, in this barrel of honey there is a grain of ash – the gas does not pass into the afterburner in a natural way, but is supplied by electronics. That is, without electricity, the boiler will not work. Judging by the reviews, pyrolysis boilers work best on wood. Many pyrolysis plants are still technically complex, they are controlled through automation or even an application on a smartphone.
Pros and cons high efficiency effectively work on wood fires not all pyrolysis boilers run on coal energy dependence priceHeat exchanger material
Most often you can find steel heat exchangers – they are light, inexpensive, insensitive to temperature changes. However, they are vulnerable to high temperatures – they can burn out or melt. And they can rust, even with a special coating. Boilers with such a heat exchanger do not live long: 12-18 years is their limit. It is worth paying attention to the wall thickness – the thicker the better. In any case, at least 4 mm.
The second option is cast iron. Such a boiler is not so easy to drag and install. However, it will faithfully serve you for at least 25 years, and maybe more, and is also resistant to burnout – which means it will “accept” any type of coal, including anthracite that flares up to high temperatures. However, such a colossus requires not only transportation costs, but also imposes increased requirements on the quality of the floor – it must be very durable in order to withstand a weight of 100 or more kg. And a sharp access of cold air can cause cast iron to crack, so in such conditions it is recommended to take care of the safety of the boiler and install a three-way valve.
Single-circuit or double-circuit?
Single-circuit boiler – for heating the room and only him.
double circuit – if you also want to take a hot shower or walk on the warm floor. It will cost, of course, more expensive, but not much (usually a third more), and is associated with certain difficulties. For example, a feature of "solid" boilers is the cyclical nature of the fuel supply: it either flares up or fades out, and this affects the degree of water heating. This is bypassed by installing a system with a heat accumulator (it is also a buffer tank that equalizes temperature drops). Apparently, because of this, there are not so many double-circuit models of solid fuel boilers – they are found only among the classic ones.
Automation
• Economy models of solid fuel boilers are manually controlled. More expensive models already ignite the fuel automatically, they have special systems that increase efficiency, ensure uniform combustion, and so on. Of the benefits – automation can be bought separately. It will cost about 70% of the price of the economy model of a "solid" boiler.
How to calculate power
• For a full calculation of the boiler power, it is recommended to contact a specialist, however, an approximate calculation is as follows:
- If the house or cottage is poorly or moderately insulated, the wall thickness is 2 bricks, the ceilings are up to 3 m high, then 1 kW per 10 sq.m is enough for such a house.
- For everyone, it’s better to take it with a margin, add about a quarter of the power – what if it’s frosty?
- If you need to put a double-circuit boiler or heat accumulator, it is better to add 30%.
