Stainless steel heat exchangers for gas boilers 24-28KW

Product Introduction

24-28KW Stainless Steel Thermal Heat Exchangers for Household Condensing Gas Boiler Heating and Hot Water Applications

Introduction & Key Advantages

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

The stainless steel condensing heat recovery exchanger is an efficient boiler component that captures the latent heat contained in flue gas vapor and converts it into usable heating energy.

• Provides high thermal efficiency of up to 107–109% for modern condensing boilers.
• Improves heat recovery efficiency and minimizes wasted energy.
• Helps reduce fuel costs and supports energy-efficient heating applications.

What Is a High Efficiency Gas Boiler Heat Exchanger?

A high efficiency gas boiler heat exchanger combined with full premix combustion technology ensures uniform mixing of fuel gas and air before combustion. The system delivers:

• Reduced exhaust emissions and cleaner combustion.
• Stable heat transfer performance and dependable service life.
• Better heating output from the same fuel supply.

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
