Stainless Steel Boiler Heat Exchangers 24-28KW for Energy Efficient Heating Applications

Product Introduction

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

Where Is It Used?

Key Advantages

1. Much Higher Efficiency — Saves Money

· Thermal efficiency: 107–109% (vs. 85–95% for ordinary boilers)

· Less gas used for the same heat output

· End users pay less on their energy bills

2. Stainless Steel — Built to Last

· Made from stainless steel

· Handles acidic condensate (pH 3–5) with no problem

· No rust. No corrosion. No leaks.

· Expected service life: 15+ years

3. Low Emissions — Clean & Green

· Meets EU ErP Directive and all major global environmental standards

· Helps customers stay ahead of tightening regulations

4. Smart Design — Better Performance

· Spiral finned tube structure increases heat transfer surface by 40–60%

· Multi-pass water circuit design for stronger turbulence and better heat exchange

· Low water resistance — works with smaller pumps → saves electricity

5. Quiet & Stable

· Smooth flame, no pulsation

· Quiet operation — suitable for homes and hospitals
