24-28KW Stainless Steel Condensing Boiler Heat Exchanger for High Efficiency Heating Systems

Combi Stainless Steel Main Thermal Heat Exchangers 24-28KW

Product Introduction

High Performance Stainless Steel Heat Exchangers 24-28KW for Condensing Gas Boilers and Residential Hot Water Heating Systems

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. Superior Energy Efficiency — Reduces Operating Costs

· Thermal efficiency reaches 107–109% compared with 85–95% for conventional boilers
· Requires less fuel consumption while delivering the same heating performance
· Helps homeowners reduce energy expenses and improve overall heating efficiency

2. Stainless Steel Construction — Designed for Long-Term Reliability

· Manufactured with high-quality stainless steel materials
· Excellent resistance to acidic condensate with a pH range of 3–5
· Prevents rust, corrosion, and leakage issues during long-term operation
· Provides an expected service life of 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
