What is a Condensing Boiler?

Condensing Boiler and Its Working Principle

A condensing boiler is a modern heating system designed to recycle waste heat using condensation technology to produce energy efficiently. With its ability to produce heat and recycle waste energy, it is an ideal solution for high performance and sustainability.

Difference from Traditional Boilers

Traditional gas and liquid-fueled boilers release the water vapor in exhaust gases directly into the atmosphere. In contrast, condensing boilers absorb the waste heat, increasing efficiency and reducing emissions.

Efficiency Rate

Condensing boilers achieve maximum efficiency when the return water temperature drops below 55°C. The efficiency rate, based on the higher heating value of the gas, can reach up to 109%.

Why Choose a Condensing Boiler?

Environmental Benefits

As the impacts of global warming intensify, the importance of environmentally friendly systems grows. Condensing boilers meet this need by offering high efficiency and reduced harmful gas emissions.

Energy Efficiency

Rising energy costs and diminishing resources make energy-efficient systems a priority. Condensing boilers produce more heat with less fuel, ensuring significant energy savings.

Standards and Regulations

Many European countries mandate the use of condensing boilers in specific applications as part of energy efficiency regulations aimed at reducing environmental impact.

Condensing Boiler Systems

Condensation Technology

This technology recovers the latent heat of vaporization by condensing water vapor produced during combustion. It reduces flue gas temperature and ensures fuel savings.

• Fuel Savings: Reduces carbon dioxide (CO) emissions by up to 80% and nitrogen oxides (NOx) emissions by up to 90%.

Cascade System

The cascade system allows multiple boilers to work synchronously, providing energy efficiency in large structures.

• Advantages:
  • Redundant operation ensures uninterrupted heating during malfunctions.
  • Easy maintenance and scalability up to 120 devices.
  • Simple management with an electronic control unit.
• Disadvantages: A malfunction in the external control panel can affect the entire system.

Advantages of Wall-Mounted Condensing Boilers

Wall-mounted condensing boilers, promoted in central heating systems under Energy Performance Regulations, are favored for their compact design and low noise levels.

• Energy Savings: Provides up to 20% energy savings.
• Durability: Offers a long-lasting, environmentally friendly heating solution.
