Wall-mounted condensing boiler for heating on natural gas (propane) with flue gas discharge through the wall, roof, or via a chimney shaft or skylight.
Condensing boilers have approximately 15 % lower energy consumption compared to conventional boilers, and the content of harmful CO2 and NOx is reduced to a minimum. These advantages then translate into lower heating costs.
