Combi 24-28KW Stainless Steel Heat Exchangers for Condensing Gas Boiler Systems

Product Introduction

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

Introduction & Key Advantages

What Is a Stainless Steel Condensing Heat Exchanger?
This type of heat exchanger recovers heat from water vapor inside flue gases and transforms the vapor into water to maximize energy recovery.
Thermal efficiency can reach 107–109%, compared with traditional systems at 85–95%.
Higher efficiency means less fuel usage and lower operating expenses.
What Is a Gas Condensing Heat Exchanger?
A full premix burner combines gas and air completely before combustion, delivering:
· Reduced harmful emissions
· Consistent boiler operation
· Improved heating output from every unit of fuel

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)
