Heating Systems Stainless Steel Gas Boiler Vaillant Heat Exchanger 24-28KW

Stainless Steel Gas Boiler Heat Exchangers 24-28KW

Product Introduction

 Residential Condensing Gas Boiler Stainless Steel Heat Exchangers 24-28KW for Central Heating and Household Hot Water Supply

Introduction & Key Advantages

What Is a Premium Stainless Steel Heat Exchanger for Condensing Gas Boilers
   A condensing heat exchanger captures latent heat energy from flue gas vapor by turning it back into water.
   Up to 107–109% thermal efficiency — outperforming traditional heat exchangers (85–95%).
   Greater heat recovery. Less fuel waste. Lower heating bills.

What Is a Gas Condensing Heat Exchanger?
Gas and air are perfectly premixed before combustion in a full premix system. This efficient burn delivers:
  Minimal harmful gas emissions
  Dependable and safe functionality
  Enhanced heat output from identical fuel use

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
