Condensing Boilers

Condensing boilers operate at 90-95% efficiency and reduce carbon emissions compared to conventional boilers at 70-80%. 

They capture condensate moisture from hot flue gases before it is expelled through a condensate drain and then recycle the heat it contains. 

This condensing process immensely reduces the temperature of the flue, carbon emissions and gas intake which saves you money and helps run your boiler at high efficiency.

Benefits of condensing boilers include:

  • High thermal efficiency
  • Environmental friendliness – lower carbon footprint
  • Light weight and small dimensions
  • Durability / reliability
  • Low noise production
  • Large regulating range
