1. What Is a Wall-Hung Boiler?

A wall-hung boiler is a high-performance heating unit designed to provide central heating for buildings with high heating demand such as apartment blocks, hotels, and commercial facilities. Thanks to their compact design, these boilers can be mounted on the wall, occupying significantly less space than floor-standing boilers and offering ease of installation and space efficiency—particularly in modern boiler rooms.

HS CODE: 8403.10.10

2. What Is a Condensing Boiler? How Does It Work?

A condensing boiler is an advanced heating solution that recovers latent heat by condensing the water vapor contained in combustion exhaust gases.

How Does It Work?

Copa condensing boilers utilize specially engineered heat exchangers to recover energy from hot flue gases that would otherwise be discharged. This process increases combustion efficiency while minimizing fuel consumption. They deliver maximum performance especially in low-temperature systems (such as underfloor heating or properly sized radiator systems), significantly reducing operating costs.

3. What Are Wall-Hung Boiler Capacities?

Wall-hung boilers offer a wide power range depending on project size. In the Copa product portfolio, boiler capacities typically start from 65 kW and extend to 150 kW and above for single units. Required capacity is calculated by our expert engineers based on total heated area, building insulation level, and regional climate conditions.

4. What Is a Cascade Boiler System? How Does It Work?

A cascade system is the synchronized operation of multiple wall-hung condensing boilers connected to function as a single system.

How Does It Work?

The system activates boilers sequentially according to total heating demand. For example, when outdoor temperatures are moderate, only one boiler operates; as demand increases, additional units are automatically activated. This “equal load sharing” principle extends equipment lifespan and delivers significantly higher energy efficiency compared to a single large-capacity boiler. With Copa cascade solutions, it is possible to connect up to 15 units to achieve very high total capacities.

5. How Can I Find the Most Suitable Boiler?

Selecting the most efficient boiler for your project or building requires professional expertise. Incorrect capacity selection may lead to energy waste or insufficient heating performance.
