FAQ: 10 frequently asked questions about heating boilersAnswers to common questions in the section "heating boilers"

Comfortable warmth in every home

The Beretta CIAO GREEN 25 CSI condensing gas boiler has an increased efficiency of up to 107.2% and is capable of heating both residential and non-residential premises with an area of up to 160 m². The second circuit of this boiler is responsible for hot water supply and can operate independently in the summer. The closed combustion chamber of this boiler is equipped with a secondary heat exchanger, which increases its efficiency by using the energy released as a result of fuel combustion. This innovative approach to heating saves energy and provides faster, more consistent heating. The boiler does not use oxygen during the combustion process, since combustion air is taken from the street through the chimney. Therefore, the room can be completely isolated from the outside atmosphere. Thanks to its compact dimensions, the condensing boiler can be installed in confined spaces such as niches, basements, boiler rooms, warehouses, as well as in private houses and apartments.

Intuitive controls

This boiler is equipped with automation that controls all processes, including starting and stopping heating, as well as maintaining the temperature regime by changing the flame modulation. The user only needs to select the desired climate mode, and the rest of the operations are performed automatically. Separate sensors ensure process safety, including protection against overheating and melting of the heat exchanger in the absence of water, as well as protection against freezing of the liquid in the system, which maintains the functionality of the circulation pump. One of the characteristic features of this boiler is the branded SARA mode, which automatically adjusts temperature conditions based on thermostat readings. This allows you to achieve an optimal balance between the efficiency and economy of the boiler and will be useful if the owners are away for a long time.
