Wall-hung gas boilers for household and small offices – with traditional (conventional boilers) and advanced (condensing) technology with efficiency till 108%
  • Condensing wall-hung boilers

    Condensing wall-hung boilers could use so called "latent heat" that contents in the flue smoke gases. It is a heat of vaporized water that was build due combustion chemical reaction from the gas and oxygen from air - this water immediately after its building absorbs the certain part of heat energy from hot flame and becomes a steam, and it is not so easy to take this part of heat energy back and use it for heating. Unlike conventional boilers the condensing boilers could take this "latent heat" back from flue smoke gases - because special technology they can make the smoke gases cooler and steam from smoke gases being condensed inside special construction of heat exchanger and give it "latent heat" back to the heating water. Comparing with conventional boilers the condensing boilers have efficiency more than 100% (normally about 106-108% comparing with 90-91% by conventional boilers).

  • Conventional wall-hung boilers (non-condensing)

    Non-condensing wall-hung boilers use traditional heat exchangers and more cheaper and simple technology, they could not use so called "latent heat" that contents in the flue smoke gases. It is a heat of vaporized water that was build due combustion chemical reaction from the gas and oxygen from air - this water immediately after its building absorbs the certain part of heat energy from hot flame and becomes a steam, and it is not so easy to take this part of heat energy back and use it for heating. Unlike condensing boilers the conventional  boilers could not take this "latent heat" back from flue smoke gases - its "latent heat" disappears in the atmosphere. Comparing with condensing boilers the conventional boilers have efficiency not more than 90-91%  (comparing with 106-108% by condensing boilers), but they are more simple for construction and much cheaper.
