Product Description

24-28KW Gas Boiler Stainless Steel Heat Exchangers

Product Introduction

 Energy Efficient Stainless Steel Heat Exchangers 24-28KW Suitable for Condensing Gas Boilers, Residential Heating and Hot Water Systems

 

Introduction & Key Advantages

 

What Is a Stainless Steel Condensing Boiler Heat Recovery Exchanger
   A condensing heat exchanger absorbs additional heat from hot flue gas moisture and converts it into usable thermal energy.
   Up to 107–109% thermal efficiency — significantly higher than standard heat exchangers (85–95%).
   More heating output. Less wasted fuel. Lower operating costs.

What Is a Gas Condensing Heat Exchanger?
In a full premix system, fuel gas and air are evenly mixed before combustion. This clean-burning technology ensures:
  Reduced exhaust emissions
  Smooth and stable operation
  Improved heating efficiency from equal fuel input

 

Where Is It Used?

Application

Examples

Home Heating

wall-hanging boilers,

floor-standing boilers

Hot Water

Instant water heaters, combi boilers

Commercial Buildings

Hotels, hospitals, schools, offices

Industrial

Process heating, waste heat recovery

Pool Heating

Commercial swimming pools, spa systems

 

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

Emission

Ordinary Boiler

NOx

≤ 30 mg/kWh

80–200 mg/kWh

CO

≤ 10 mg/kWh

50–150 mg/kWh

· 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
