Stainless Steel Gas Boiler Heat Exchangers 24-28KW

Product Introduction

Built for modern residential condensing gas boilers, the 24-48KW Stainless Steel Heat Exchanger enables efficient heat recovery and heat transfer for heating systems and domestic hot water applications. Its high strength stainless steel construction delivers dependable performance in high temperature and pressure environments, helping achieve improved energy efficiency, reduced energy consumption, and long-term system reliability.

Introduction & Key Advantages

What Is a Durable Stainless Steel Heat Exchanger for High Efficiency Condensing Boilers?

A durable stainless steel heat exchanger improves boiler efficiency by recovering latent heat from exhaust gas through condensation and returning the recovered energy into the heating system.

• Delivers up to 107–109% thermal efficiency for modern condensing boilers.
• Provides significant energy savings compared with traditional 85–95% heat exchangers.
• Ensures efficient heating performance with reduced fuel demand.

What Is a Gas Condensing Heat Exchanger Used For?

A full premix combustion system creates a complete mixture of gas and air before ignition, allowing the boiler to achieve optimized combustion. Benefits include:

• Very low emission levels for cleaner operation
• Reliable and secure heating performance
• Maximum heat generation from available fuel energy

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
