High Efficiency 24-28KW Stainless Steel Heat Transfer Units for Condensing Gas Boilers, Indoor Heating and Hot Water Systems

Introduction & Key Advantages

What Is a Stainless Steel Thermal Recovery Heat Exchanger for Condensing Boilers

A stainless steel thermal recovery exchanger helps condensing gas boilers recover hidden heat from exhaust flue gases by cooling water vapor into liquid condensate and transferring additional heat energy into the heating system.

• Delivers up to 107–109% heating efficiency for improved energy utilization.
• Recovers more thermal energy compared with traditional boiler heat exchangers.
• Reduces gas consumption while improving heating performance and operating cost efficiency.

What Is a Gas Condensing Heat Exchanger System?

A gas condensing heat exchanger system uses full premix combustion technology, where gas and air are evenly mixed before ignition to achieve optimized combustion efficiency. Key advantages include:

• Lower pollutant emissions for cleaner heating solutions.
• Consistent combustion performance and reliable operation.
• Increased heating capacity without increasing 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

· 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)
