Wood log heating technology in detail

2 or 5 years material warranty depending on the boiler type on electrical components and gear motors. 2-year full warranty (material, labour and travel costs) on all parts of the system.

The lambda sensor regulates the exact right amount of fuel in each output range, depending on the quality of the wood chips or pellets. This is the only way to guarantee optimum, i.e. economical and low-emission combustion, which also saves you energy and money with more than 95% efficiency!

Features an exceptional, above-average design and simple operation. It controls the entire heating system from combustion to buffers, heat circuits and boilers.

Easily and quickly make changes to your heating system from anywhere or call up information around the clock. User-friendly interface, switch heat circuits on & off, change heating times & temperatures, etc….

Refractory fireclay has proven to be the best material in terms of heat storage capacity, durability and function: The high combustion chamber temperature at full and low load contributes to the high efficiency and lowest emissions.

The generous filling door allows convenient filling of the very large filling chamber (166 / 222 lt). The log length can be up to 600 mm. A specially optimised filling chamber lining ensures efficient combustion without tar formation in the filling chamber. The top smouldering gas duct extracts the remaining smouldering gases when the stove is reloaded.

Optimum afterburning and thus overall perfect combustion, both at full and partial load, is ensured by the preheated secondary air, in conjunction with the burnout stone. This leads to very high efficiencies and low emission values.

Depending on the power requirement, the ‘Lambda-Touch-Tronic’ regulates the speed of the EC intake fan. This concept guarantees optimum combustion with low flue gas temperatures and maximum efficiency. With the optional rotatable induced draught housing, the flue pipe connection can be steplessly rotated laterally to the left or right.

In order to fully utilise the energy gained, we direct the heat flow as close as possible to the heat exchanger with the help of screw coils in a spirally extended flow path, this increases the efficiency.

The boiler is equipped with highly efficient ‘all-round’ insulation. This means that not only the doors and the complete outer shell are insulated, but also the front door.

Hargassner offers you a perfectly matched layered accumulator series. No matter whether you choose a layered buffer or a layered hygienic accumulator.

The return temperature is kept high by a return mixer group mounted directly on the boiler. At the same time, the heat is sent to the buffer or the heating system.

Gone are the days of manual heat exchanger cleaning. The patented, automatic heat exchanger cleaning takes care of everything for you. Now new: with linear guide. This guarantees constant, high efficiency and reduces your cleaning effort.

Just put more wood and heating material in the filling chamber, the intelligent automatic control and automatic ceramic ignition do the rest. It increases your operating comfort to a maximum.
