High Efficiency Boilers

Gas-fired condensing boilers are highly efficient, environmental-friendly and cost-reducing. Through the process of combustion water is heated and flue gases pass into the chimney. These flue gasses, which are mostly hot water vapour, are not lost, since gas-fired condensing boilers extract the heat and transfer the obtained energy into the heating circuit. Gas-fired condensing boilers can be used both for hot water preparation and heating.
