25 Bar Operating Pressure Stainless Steel Gas Boiler Heat Exchangers Household Hot Water

Gas boiler Stainless steel heat exchangers 24-28KW

Product Introduction

 24-28KW Stainless Steel Boiler Heat Exchange Modules Designed for Condensing Gas Heating and Household Hot Water Use

Introduction & Key Advantages

What Is a Stainless Steel Heat Recovery Unit for Condensing Boilers
   A condensing heat exchanger extracts additional heat from moisture in flue gases by condensing vapor into water.
   Up to 107–109% thermal efficiency — significantly above ordinary heat exchanger systems (85–95%).
   Higher energy utilization. Less fuel waste. Lower operating costs.

What Is a Gas Condensing Heat Exchanger?
In a full premix burner, gas and air are thoroughly blended before ignition. This clean-burning technology delivers:
  Low harmful emissions
  Consistent and safe performance
  Higher thermal efficiency using the same amount 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)
