The Stainless Steel Heat Exchanger 24-28KW is engineered for modern condensing gas boilers used in household heating and hot water supply systems. Featuring strong corrosion resistance and efficient thermal conductivity, it helps maximize boiler efficiency while supporting safe and dependable long term operation. Suitable for a wide range of residential heating applications.
Introduction & Key Advantages
What Is a High Efficiency Stainless Steel Heat Exchanger for Condensing Gas Boilers
A condensing heat exchanger recovers heat from exhaust gas vapor by condensing it into water and reusing the released energy.
Up to 107–109% thermal efficiency — far exceeding normal heat exchangers (85–95%).
More efficient heating. Reduced fuel use. Lower utility bills.
What Is a Gas Condensing Heat Exchanger?
In a full premix combustion system, gas and air are completely mixed before burning. This process delivers:
Extremely low harmful emissions
Reliable and secure operation
Improved heat generation from the same fuel input
