Condensing Boiler
Modern gas boiler that uses the heat from flue gases to be 15-30% more efficient.
What is Condensing Boiler?
Condensing boilers recover heat from the water vapor in the combustion gases, which traditional atmospheric boilers dumped out of the chimney. This gives them a seasonal efficiency of 100-105% (vs 85% for atmospheric ones).
When you encounter it in an emergency & typical cost
Mandatory in many new builds. Replacement cost for an old boiler: €1,800-2,800. Amortization from lower energy consumption: 3-6 years.
