Combi Stainless Steel Main Thermal Heat Exchangers 24-28KW Industrial Boilers

Combi Stainless Steel Main Thermal Heat Exchangers 24-28KW

Product Introduction

High Durability Stainless Steel Heat Exchangers 24-28KW Designed for Condensing Gas Boilers and Household Water Heating Applications

Introduction & Key Advantages

What Is a Stainless Steel Heat Optimization Exchanger for Condensing Boilers
    A condensing heat exchanger extracts hidden thermal energy from flue gas water vapor and converts it into reusable heat.
    Up to 107–109% thermal efficiency — much higher than standard heating systems (85–95%).
    More efficient heat production. Reduced fuel use. Better savings.

What Is a Gas Condensing Heat Exchanger?
Gas and air are perfectly combined in a full premix combustion system before burning. This clean process delivers:
  Minimal harmful gas emissions
  Consistent and safe functionality
  Improved thermal efficiency from equal fuel usage

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)
