96 – 98% efficiency

96-98 randamentThe high efficiency of the pellet boiler is kept constant throughout the whole period of use due to the design of the ecoHORNET burner, to the combustion dynamics and because of the burning control achieved by full automation. The power efficiency does not depend on the raw material from which the pellets were manufactured. The equipment is perfectly adaptable to all raw materials for manufacturing pellets while the nominal power remains constant.


A technical room in a heating unit

The ecoHORNET pellet boiler is fully equipped to distribute heat on 2 independent heating circuits with circulation pumps, mixing valves, ambient thermostat and anti-condensation circuit. It also contains a large amount of thermal agent which allows an efficient operation without puffer and has a built-in DHW serpentine. The installation time and the annoyance produced by the plumbers are significantly reduced and the mistakes of mounting the equipment room or incompatible materials are also avoided.

● ON-OFF functioning
The ecoHORNET pellet boiler are not modulating the power, they are working at nominal power throughout the operation until the temperature reaches the programmed heating point, then they stop completely. ADVANTAGE: low power consumption, no tar is formed on the walls of the boiler when the air intake is low – as in the case of modulation, so the premature wear due to excessive operation is avoided.

● Easy of use
Thanks to the efficient combustion process and the quality of the materials, the boiler does not require repeated cleaning or servicing operations. The equipment is factory programmed. The user is not required to make any settings or adjustments.

● 100% combustion control
The forced draft operation ensures a rate of 100% control of the flow of the oxygen required for combustion, the combustion is uniform throughout the mass of pellets being in the burner. Each pellets’ particle receives the oxygen required for complete combustion so the combustion gases have a minimum content of particles, moisture or organic compounds.

● 100% safe 
The safety of operation is ensured by a high performance system that controls all the equipment functions. It includes as standard and all the safety components of a modern heating system.

● 100% quality materials

The ecoHORNET equipment are designed for long term use.

The ecoHORNET multisystem patented burner develop combustion temperatures of pellets over 1250 ° C, so as the whole calorific value of the fuel is harnessed, turning it into heat. The combustion efficiency is close to 100% and the burning is complete, without smoke traces in the flue gases. The ecoHORNET burner is mobile, self-cleaning and accelerates the burning when using energetic weaker pellets. The burner and the combustion chamber are made of special stainless steel resistant to temperatures over 1300 ° C and to temperature variations.


Heat exchanger

The heat exchanger has been especially designed to operate at high temperatures, with no wear over time, and to ensure the optimum transfer of the energy resulting from the burning of pellets. The heat exchanger is made of special steel for boilers, according to the latest regulations in force. It contains a large amount of heating agent and takes over the functions of a heating agent accumulator (puffer). An efficient operation of the heating unit without a heating agent accumulator (puffer) is also possible. The efficient heat exchanger transfers the energy produced by burning pellets in the heating agent – even if inside of the burner there are developing temperatures above 1250 ° C, the temperature of the exhaust flue gases does not exceed 60-80 ° C. The difference in thermal energy is transferred into the heating agent. Hence the exceptional efficiency, which translates to the user in great fuel economy. The heat exchanger uses 2 areas of heat exchange, so it takes the flame radiation as well as the convection of the flue gases.


Blast-heating apparatus

As a novelty, we introduced the third exchange zone, a blast-heating apparatus, that uses the exhaust gas temperature of 100-120°C to pre-heat the return heat carrier before entering the heat exchanger. No condensation is formed in this blast-heating apparatus because, following the combustion to more than 1250°C in the multisystem burner, the burnt gases are “dry”, they do not contain water vapors.



Built-in DHW serpentine

Inside the heating unit, a high efficiency DHW serpentine is built-in, for producing the hot water for consumption. The hot water for consumption is produced extremely efficiently, because the serpentine is completely immersed in the hot heat carrier from the heat exchanger, the exchange surface is much larger than the one of the outside mounted boilers with winding pipes. The use of the pellet boiler during the summer time is economical and efficient, only for the production of hot water for consumption, the heating unit starts only every few days, depending on consumption.



Combustion speed-up and grill cleaning system

The equipment is equipped with combustion speed-up mechanisms, to keep constant the rated power, even if there are used lower caloric power pellets. Thus, even if there are used pellets made of straws, grasses, the equipment will produce the same amount of heat energy, as in the case of wood pellets use.



Combustion control by forced draft

The combustion without smoke and tar in the exhaust gases allows the operation with forced draft. The exhauster is mounted on the burnt gases outlet. The operation with forced draft ensures 100% the control of the oxygen flow necessary for combustion, the combustion is uniform in the entire mass of pellets found in the burner, it is accomplished the complete combustion, including the combustion of the smoke particles. Every pellet particle receives the oxygen necessary for the complete combustion, thus the burnt gases have a minimum content of particles, humidity or organic compounds. The burnt gases evacuation is not influenced by the atmospheric conditions.


Automatic feeding system

The pellet feeding is performed automatically, by a screw conveyer operated by a capacitive sensor. The pellets container is independent from the heating unit body, depending on the available space, it can be used the one from the standard endowment, 600/800 liter, or other high capacity container. The pellet feeding system is provided with safety elements which prevent the damage if, accidentally, foreign bodies are dragged along.




By the complete automation with performance equipment  and software developed together with the Austrian company SIGMATEK GmbH &Co KG,  it is performed the total control of the heat energy production, as well as of all systems composing the installation and made possible their integration in complex heating systems. The color touch display will supply complete information concerning the equipment operation. The equipment may be monitored and programmed remotely, via an Internet connection, so you always have control of your heat energy production system.



...Safety systems

Electrical protection set: Because the electricity fluctuations/outages that may affect the electronic components of the heating unit or may perturb the proper operation, we introduced in the standard endowment a protection set: UPS with functions of inverter, stabilizer, rectifier and 2 accumulators.
Flow transducer ( flow switch): It senses the heat carrier movement in the installation and ensures the protection in case of heat carrier loss, blocking of the circulation pump or of the heating circuit.
Other safety elements: pressure gauge,
heat carrier temperature gauge ; vent ; safety valve ( 5bar).
