Combi Condensing Gas Boiler Stainless Steel Heat Exchangers Rated 24-28KW
Combi Condensing Gas Boiler Stainless Steel Heat Exchangers Rated 24-28KW
Product Introduction
24-28KW Condensing Gas Boiler Stainless Steel Heat Exchangers for Household Heating and Hot Water Applications
Introduction & Key Advantages
What Is an Energy Efficient Condensing Stainless Steel Heat Exchanger?
An energy efficient condensing stainless steel heat exchanger is designed to recover additional thermal energy from flue gas vapor. Through condensation technology, the exchanger converts vapor into liquid water and captures the hidden heat that would otherwise be lost.
The system can reach 107–109% thermal efficiency, exceeding conventional heating equipment efficiency levels of 85–95%.
Key advantages:
- Significant energy savings
- Reduced fuel consumption
- Higher heat recovery performance
- Improved heating efficiency
What Is a Gas Condensing Heat Exchanger?
A gas condensing heat exchanger uses a full premix design to ensure precise gas and air mixing before combustion, optimizing the combustion process.
Benefits include:
- Lower environmental impact
- More stable heating operation
- Higher thermal output efficiency
