Heating systems with condensing technology utilise almost all the energy contained in the exhaust gases from pellets. This additional benefit of approx. 16.3% with pellets is simultaneously the energy saving made possible by condensing technology. This saves money. This allows condensing boilers like the Pellematic Condens to achieve efficiency levels of up to 107.3%*. Condensing technology subjects the flue gas quite naturally to additional cleaning – emission levels are therefore significantly lower than the legal limits. Pellet boilers with condensing technology achieve a reduction in dust emissions of 40–50% compared to standard boilers without condensing technology. Modern pellet boilers are therefore not comparable in any way with old wood boilers either as regards emissions. So a condensing boiler helps not only to reduce energy costs, but also to protect the climate. Due to their high efficiency with lowest emission levels, pellet condensing boilers also qualify for particularly attractive subsidies from the state. Prerequisites for installing a condensing boiler: A corrosion-resistant chimney Return temperatures of approx. 30–40 degrees A drain for the discharged condensate *Test bench value related to the lower calorific value of the fuel, determined at continuous full load ideal operation according to EN303-5 Practical values and seasonal efficiencies may deviate due to local conditions, fuel properties, manufacturing tolerances and individual operating modes. The data do not refer to individual products, but serve only for comparison purposes between boiler types.
