Combi Durable Stainless Steel Heat Exchanger Solutions For 24-28KW Condensing Gas Boilers

Combi Durable Stainless Steel Heat Exchanger Solutions for 24-28KW Condensing Gas Boilers

Product Introduction

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

Introduction & Key Advantages

What Is a Stainless Steel Condensing Heat Exchange System?
The system recovers hidden thermal energy from hot flue gas vapor by converting it into liquid water.
Up to 107–109% thermal efficiency can be achieved, far above ordinary heat exchanger performance.
Deliver more heat while reducing fuel usage and heating expenses.
What Is a Gas Condensing Heat Exchanger?
Full premix combustion technology mixes gas and air thoroughly before burning, resulting in:
· Very low exhaust emissions
· Consistent and safe performance
· Higher thermal output 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)
