The new range of AVANTTIA NG floor standing gas condensing boilers manage to improve the performance, thereby reducing consumption thanks to the innovative design of the combustion chamber, while offering high-comfort features with great ease of installation, use, and maintenance.
Taking advantage of the condensation technology, savings in fuel consumption of about 20% can be achieved compared to standard boilers.
The gas has an energy capacity of 111% over LHV. To take full advantage of this capacity, the water vapor from the combustion gases should be converted into water.
The AVANTTIA NG boiler features an innovative boiler heat exchanger that allows the temperature of the combustion gases to be reduced below the dew temperature, maximising the energy capacity of the fuel.
By associating this boiler heat exchanger with a premix burner and an electronic control over the system, a boiler with the best energy rating of its category is obtained, in compliance with the ErP Directive.
According to the ERP regulation of 26/9/2018 NOx emissions < 56mg/kWh.
