After intensive development work, the first HERZ pellet boiler with condensing technology was introduced in 2016. The state-of-the-art combustion technology and high-quality system components result in increased efficiency of pellet boilers as well as a reduction in dust emissions.
The extremely compact condensing boiler is the ideal solution for both new buildings and modernisation projects.
The big advantages of the HERZ pelletstar CONDENSATION 80-101 kW
- The heat exchanger surfaces made of stainless steel are cleaned automatically via a fl ushing mechanism as well as via the integrated turbulators, even during heating operation and therefore no manual cleaning is necessary.
- A consistently high level of effi ciency by purifi ed heat exchanger surfaces means lower fuel consumption.
- The steam which is contained in the flue gas is cooled down so far that liquid condensate is formed in the heat exchanger. With this cooling process (liquefaction) condensing heat is released and can be used for heating purposes. Due to the condensing technology effi ciencies up to 106% can be achieved.
- Made of high temperature resistant refractory concrete (SiC) – for longest lifetime
- The cumbustion grate is automatically cleaned by tipping the double grates against matrices.
- Due to the clean combustion grate an optimal air supply is guaranteed.
- The ash that accumulates in the combustion chamber is thrown into the ash screw below and automatically transported to the external ash box on the front.
- A built in lambda probe, which monitors continuously the flue gas content values, detects fuel quality changes and ensures optimum combustion and low emission values.
- The lambda probe controls the air supply and ensures the cleanest combustion, even in part load operation.
- The results are lower fuel consumption and lowest emission values even with different fuel qualities.
- The HERZ pelletstar CONDENSATION is the ideal solution for new buildings as well as for renovations. The heat distribution can be done via a low temperature system (underfl oor heating) or a high temperature system (radiators). Depending on requirement the pelletstar CONDENSATION delivers the correct temperature also without buffer tank.
- Due to the modular design, the insertion and assembly can be carried out very quickly and easily. In addition, the system can be placed on two sides (back & side) in flush with the wall and provides therefore, also for existing boiler rooms with limited space, an optimal solution.
