Product Description

Combi Stainless Steel Heat Exchanger 24-28KW for High Efficiency Condensing Gas Boilers

Product Introduction

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


Introduction & Key Advantages


What Is a Condensing Boiler Stainless Steel Heat Exchanger?

A condensing boiler stainless steel heat exchanger is engineered to recover latent heat from hot flue gas generated during combustion. The exchanger condenses water vapor inside the exhaust gas, converting wasted heat into additional usable heating energy.

It offers up to 107–109% thermal efficiency, compared with traditional boiler systems that usually achieve only 85–95% efficiency.

Advantages:

  • Higher heat recovery efficiency
  • Lower fuel consumption
  • Improved boiler energy savings
  • Enhanced system performance

What Is a Gas Condensing Heat Exchanger?

A gas condensing heat exchanger features a full premix combustion system that accurately mixes gas and air before combustion, improving combustion quality and heat transfer efficiency.

Key features:

  • Reduced exhaust emissions
  • Stable boiler operation
  • Increased heating output


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

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

· Full technical support: heat load calculation, product selection, testing

· Your brand logo can be applied (OEM/ODM welcome)
