Product Introduction

Premium Stainless Steel Heat Exchangers 24-28KW for Residential Condensing Boilers and Water Heating

Introduction & Key Advantages

What Is a Stainless Steel Heat Recovery Exchanger for Condensing Boilers
A condensing heat exchanger extracts hidden heat from water vapor in hot flue gases and converts it into useful heating energy.
Up to 107–109% thermal efficiency — higher than conventional heat exchangers (85–95%).
More thermal output. Less energy waste. Lower costs.

What Is a Gas Condensing Heat Exchanger?
A full premix system mixes gas and air evenly before ignition. This clean combustion ensures:
Low exhaust emissions
Stable and safe boiler operation
Better heat efficiency with the same fuel amount

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

· No hot spots → no cracking, no breakdowns

6. OEM & Custom Service Available

· Standard sizes in stock for quick delivery

· Custom design & tooling to match your specific boiler model

· Full technical support: heat load calculation, product selection, testing

· Your brand logo can be applied (OEM/ODM welcome)
