The best solid fuel boilers with a bunker

The solid fuel single-circuit boiler Ogniwo EKO PLUS+ 25 is capable of heating private houses, commercial and non-residential buildings with an area of about 200 m². The entire process is automated thanks to an additional hopper for eco-pea coal or wood pellets. Automation independently determines the moment when it is necessary to add fuel to the firebox, so the need for manual maintenance is minimal. The built-in programmer allows you to create a work schedule for a certain period. The equipment is equipped with a Wi-Fi module for remote control via the Internet using the eCoal application. Here you can find out the current status, get information about possible failures, and change the temperature regime. Stationary settings are available via the touch panel.

The EKO series boiler belongs to eco-design class 5 and corresponds to energy efficiency A+, therefore it has low emissions of pollutants into the atmosphere. Thanks to a thoughtful internal design, fuel processing efficiency is significantly increased, and combustion products pass through special chambers, providing additional heating and minimizing emissions.

The manufacturer has provided easy access to all components of the boiler, so cleaning and routine maintenance will not cause difficulties.

The Heiztechnik Hit Pellet Duo 20 boiler belongs to energy-efficient class A+, is compatible with different types of pellets and is capable of heating rooms of about 160 m². A design feature is a cast iron grate, which allows you to burn wood and briquettes by direct loading in the event of a temporary lack of wood pellets. The proprietary flare burner with auto-ignition is compatible with fuel of various qualities, including those with a high content of impurities, is automatically cleaned and guarantees stable operation of the boiler. When using high-quality pellets, efficiency can reach 92%, which exceeds the performance of competitors. The large 300 liter hopper deserves special attention, which significantly increases the autonomy of work on one load. The heating system can operate without maintenance for more than a day, allowing you to go to work or take a weekend vacation.

The TT boiler is equipped with HT-tronic 900 automation, which automates and controls the operation of the device. You can get remote access to the system operating parameters using the optional HT-tronic Connect module, which is very convenient if you are absent for a long time or the heated room is located far from home, for example, greenhouses, farms, warehouses.

The automated TT boiler Defro Komfort Eko Lux 20 works effectively in tandem not only with conventional radiators, but also with a heated floor system, as well as indirect water heaters. For these purposes, the Lux modification provides an advanced control unit with a color touch screen and the ability to connect up to four pumps. A solid fuel boiler is suitable for mixed heating (for example, heated floors on the first floor and radiators on the second) of a private house and at the same time providing hot water at no extra cost. The power will be quite enough for 160 m², regardless of the layout. Optionally, you can connect the control module via GSM or the Internet.

Defro Komfort Eko Lux 20 easily copes with different types of fuel. The automatic feeding hopper is designed for eco-peas (wood pellets) and is equipped with an automatic reverse to eliminate blocking. At maximum loading of the bunker, the boiler's autonomy can be several days. The user can also load manually using wood, coal or suitable waste for burning. This way you can provide heating with minimal investment. The raw materials fall onto a cast iron grate, which can be removed if necessary.

The heat exchanger is made of heat-resistant sheet steel, which increases reliability and service life, but has a negative impact on the weight of the boiler, which is 472 kg. Delivery and installation of such a “crumb” will not be an easy task.

The Marten Comfort Pellet MC-20P boiler demonstrates increased efficiency and long-term autonomy due to the flare burner and a spacious 350-liter hopper. One full load of pellets is enough for several days of heating (from 2 to 4 depending on the quality of raw materials and temperature conditions) without maintenance from the user. A torch-type burner allows you to burn fuel in batches, automatically extinguish and re-ignite for more precise temperature control.

The equipment is compatible with wood and sunflower husk pellets. The latter make it possible to reduce fuel purchase costs by 3–4 times while maintaining energy efficiency.

The Marten Comfort Pellet MC-20P boiler is made of 5 mm thick sheet steel. The welding process is robotic, which guarantees high quality assembly and eliminates leaks during the entire service life, which, by the way, according to the manufacturer is 20 years. The top of the boiler is coated with powder paint, which is not afraid of high temperatures and humidity. The equipment can be installed in basements or warehouses without the risk of corrosion. The internal design includes a water jacket and a multi-level heat exchanger. All the described advantages lead to an increase in boiler efficiency up to 92%.

The fully automatic boiler Altep DUO UNI PELLET 21 adapts to the conditions of residential buildings and industrial buildings with an area of about 168 m². It can operate in heat maintenance mode with a power modulation of 25% of the nominal value, and at maximum it provides an efficiency of 91%. Heating occurs without user intervention due to a 300-liter hopper with automatic pellet feeding. This is enough for 60 hours of continuous burning and efficient heating.

The torch type burner is economical, completely burning only the necessary part of the fuel. It is capable of extinguishing and rekindling independently based on the temperature sensor readings inside the heat exchanger. Moreover, the burner cleans itself automatically and does not require regular maintenance. When using high-quality pellets, there is practically no ash left.

The manufacturer also provided for manual maintenance and loading of the boiler if it is planned to use firewood, briquettes or coal for heating. The multi-channel air supply system optimizes the combustion process to obtain maximum heat.

The Altep DUO UNI PELLET 21 TT boiler is made of 6 mm thick steel and can be operated in normal mode for many years without leaks or seal failure. The latter is also ensured by double insulation of all technological hatches. In this case, it is necessary to take into account the large weight of the boiler (440 kg). Optionally, you can install a Wi-Fi module for remote control.
