Select solid fuel boiler

Solid-fuel boilers are one of the most common. As the name implies, they use the energy of solid fuel released during combustion. New models are not just very effective, but also perfectly fit into the home interior. However, an inexperienced buyer to determine the choice is not easy. This article will help you navigate and make the right choice of solid fuel boiler, which best matches the characteristics of the heated room.

Fuel Varieties

The most important selection criterion is the type of fuel used. This is the usual wood with coal, as well as less common types of fuel - briquettes, pellets or peat.

Important! According to buyers and experts, the most attention deserves combined options with the possibility of loading alternative modern fuel.

Coal fired boilers

This is an excellent option if there are no conditions for long-term storage of firewood. The productivity of coal-fired appliances is high, and their installation is not too expensive.

Important! The main advantages - the universality of use, low costs for consumables, as well as the possibility of autonomous work. The average efficiency is about 50-70%.

Wood pellets and wood-burning appliances

Here, wood and pellets( artificial fuel pellets) are used as a heat source. The power of these devices is quite high( 200 kW).At the same time, boilers are quite economical and can be installed in any room.

Important! Pellets and wood have a long burning time, their efficiency is about 90%.

Pyrolysis boilers

Their work is based on the use of a special technology for burning wood pulp. When fuel burns, pyrolysis gas is generated, which ensures efficient heat transfer.

Important! The efficiency of the pyrolysis boiler is 85-92%.

If the room does not have access to the mains, it is best to give preference to a solid fuel boiler, which operates in an off-line mode, but with manual loading. This makes it possible to adjust the operation of the boiler in such a way that, during its operation, there are no unpleasant surprises and unforeseen problems.

Criteria for selecting

Before choosing a particular model, one should take into account such factors that influence the choice of a solid fuel boiler:

• Construction area. This is a decisive factor when choosing the power of the device, as well as when selecting fuel.
• The height of the ceiling in the room.
• The amount of heat loss. This figure is affected by the materials from which the house is made, as well as the thickness of ceilings and walls.
• Climate of the region. The main emphasis is on the air temperature in the cold season.

Important! The best option is to entrust the calculation to a qualified professional who is well versed in the types and brands of equipment.

Selection of solid fuel heater according to technical specifications

How to choose a solid fuel boiler for prolonged combustion for a house? The main selection criteria are:

• Type of fuel used.
• Combustion chamber capacity. This factor determines the performance of the device and the number of fuel loads for a certain period.
• Automation of the device.
• Product safety. Important options are: automatic shut-off and alarm.
• Power consumption parameters. Most of the boilers with solid fuels are non-volatile. However, there are models for which access to electricity is mandatory.
• Cost. Here it is impossible to say unambiguously that cheap models are the best option. As a rule, they are far from ideal for their operational qualities. But in general, you can find an option for the optimal price for each consumer.

Manual download or automatic?

When choosing a solid fuel boiler, this issue can not be ignored.

With automatic loading:

• The boiler is equipped with a special bunker for placing fuel. If coal is used in this capacity, then the particle size should not be more than 25 mm. As for pellets, they do not exceed this parameter unambiguously.
• For stable operation of the device, one load is enough for about 3-5 days, which makes maintenance of the boiler as simple as possible.
• The dimensions of the hopper may vary. Everything depends on the individual preferences of the owners.
• Fuel supply can be auger or piston.

Important! Automated feeding of coal or pellets not only simplifies the maintenance of equipment, but also makes it work as efficiently and as stable as possible.

Manual loading is considered to be traditional:

• The boiler chamber is filled with fuel manually.
• Such devices are popular in rural homes or in cottages.
• Maintenance of these devices can not be called convenient, they are not economical.
• In addition, they are large in size.

Important! Such equipment is more suitable for heating public buildings, where it is possible to place the boiler in a separate room.

Heat exchanger material

The most popular materials for heat exchangers are steel and cast iron:

• Cast iron units have a high performance in coal handling. If you use wood as fuel, the device loses significantly in power.

Important! The advantages of cast iron devices are: good maintainability and low price. Disadvantages - low efficiency( 65-75%), as well as the need for regular cleaning of the heat exchanger.

• Steel boilers use briquettes or firewood as fuel. The service life of steel aggregates at 1 load of fuel is 4-8 hours.
