Residential Stainless Steel Heat Exchangers 24-28KW for Gas Hot Water Boilers

Product Introduction

Our 24-28KW stainless steel heat exchanger is specially developed for gas heating boiler systems requiring high efficiency, durability, and stable heat transfer performance. The stainless steel construction provides excellent corrosion resistance and supports continuous operation in demanding heating conditions.

It is an ideal component for energy-efficient condensing boiler systems and residential heating equipment.

Key Features

• Designed for 24-28KW gas boiler heating applications
• High efficiency heat exchange performance
• Strong stainless steel structure with long service life
• Supports energy-saving heating operation
• Reliable performance for domestic heating solutions

Introduction & Key Advantages

What Is a Full Premix Condensing Gas Boiler Heat Exchanger in Stainless Steel
A condensing heat exchanger converts exhaust gas moisture into water to release additional thermal energy.
Up to 107–109% thermal efficiency — far beyond conventional exchanger performance (85–95%).
Higher efficiency. Reduced fuel waste. Lower energy bills.

What Is a Gas Condensing Heat Exchanger?
In a full premix system, gas and air are accurately mixed before ignition. This efficient combustion provides:
Minimal exhaust pollution
Secure and stable operation
Enhanced heating capacity with equal fuel input

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)
