Heating of commercial buildings - how to choose the right solution?

16 of October '25

When designing or retrofitting a heating system in commercial buildings - such as office buildings, schools, hotels or residential communities - investors and designers face many decisions. In addition to the choice of power and fuel type, energy efficiency, system flexibility, ease of operation and operating costs are crucial today.

Modern heat sources must combine high efficiency with compactness and reliability in continuous operation. In this context, special attention should be paid to the solutions of the Beretta brand - a manufacturer with more than 50 years of experience in heating technology, which offers equipment tailored to different types of investments.

What to pay attention to when choosing a heating system for commercial buildings?

In facilities with a high demand for heat, a good unit is not enough - the whole system counts: from modularity, to automation, to service and availability of parts.
The most important selection criteria are:

  1. Scalability - the ability to combine units into cascades to match power to current needs.

  2. Efficiency and ecology - condensing technology and low NOₓ emissions.

  3. Integration with building automation system (BMS) - to control heating intelligently and economically.

  4. Compactness and ease of installation - especially important for retrofits.

  5. Technical and service support - quick availability of service and accessories.

Power Evo-X, or EVOlucja in heating technology

For medium-sized buildings, the Power Evo-X - a state-of-the-art condensing gas boiler available in the power range from 35 to 70 kW - is the perfect solution. The device is distinguished by its compact form and lightweight design, making it suitable for both new investments and upgrades to existing boiler rooms.

One of the biggest advantages of Power Evo-X is the ability to combine up to four units in a cascade system, reaching a total output of up to 280 kW. The system can be configured linearly or "back-to-back," giving designers and installers a great deal of design freedom.

High energy efficiency (Class A), power modulation of 1:8 (and up to 1:32 in cascade) and stainless steel heat exchanger translate into low fuel consumption and long service life. Importantly, the boiler meets the NOₓ Class 6 emission standard and is suitable for operation with hydrogen-containing gas. This makes it a future-ready solution.

Operation of the Power Evo-X is intuitive thanks to an easy-to-read LCD panel, optional weather automation and the ability to manage multiple heating zones. For the installer, it is a guarantee of simple installation, and for the investor, the certainty of efficient and safe operation of the system.

Power Max and Power Max Box - high power for large facilities

For facilities with a significant demand for heat, such as hotels, schools, office buildings, sports halls or residential communities, the Beretta brand offers high-power boilers Power Max and Power Max Box.

The Power Max can be used both individually and in cascade systems (up to 110 configurations), allowing power outputs of up to several hundred kilowatts.
The Power Max Box, on the other hand, is a ready-to-use heating module in a compact housing with a power output ranging from 114 to 524 kW - with the possibility of combining into cascades of up to 1310 kW. Thanks to condensing technology, the PREMIX burner and stainless steel heat exchanger, the units provide high efficiency, low gas consumption and minimal emissions.

The systems are a popular choice for building managers and housing communities that need reliable and easy-to-service heat sources. An example is the implementation in Kąsna Dolna, where two Power Max 80P boilers were installed in a historic manor-park complex. This proves that the equipment also works well in demanding historic buildings.

Proven in practice, chosen by investors

The effectiveness of Beretta solutions is demonstrated by numerous projects throughout Poland.

In Niepołomice, two Power Max 65P boilers with acombined output of 120 kW were used in a building of a residential community, while in Ziemnice the Power Evo-X 80 boiler was juxtaposed with the Mynute X 20R, creating an efficient heating and hot water preparation system. In each case, investors emphasize compact dimensions, simple installation and intuitive operation - features that realistically translate into time and cost savings.
