Condensing Boiler overview
A condensing boiler condenses the water vapour in the flue gas, recovering latent heat that would otherwise be lost up the chimney. This provides fuel savings of up to 30% compared with conventional boilers.
Used as single units or in cascade systems (several boilers operating together) in residential, commercial and light industrial applications.
High efficiency
Flue gas temperature drops to 40-60 °C and latent heat is recovered.
Wide modulation
Efficient operation even at part load.
Low NOx
Environmentally friendly, low-emission combustion.
Cascade
Redundant, staged operation with multiple boilers.

Frequently asked questions
Does a condensing boiler need a special chimney?
Yes. Because the condensate is acidic, an AISI 316L stainless steel flue suitable for condensing operation must be used. We also manufacture chimneys.
Will it run efficiently with old radiators?
Efficiency rises as the return water temperature falls. It also works with existing radiators, and efficiency is improved with outdoor temperature compensation.
