Floor chimney gas boilers ATON Nova 25-50

Gas boilers ATON Nova - are designed for heating and hot water supply of residential houses, communal and other houses with an area of up to 400 m² equipped with water heating system.

Model range of ATON Nova chimney floor boilers is represented by both single-circuit and dual-circuit (B) devices with capacity of 25, 30, 40, 50 kW.

Special feature of ATON Nova series boilers is the usage of enhanced heat exchanger, which makes it possible to use devices in heating systems with forced circulation of coolant and working pressure up to 3 bars. The main feature of ATON Nova boilers is the possibility of connecting to them of room thermostat, wireless programmer (Android, IOS) and turbo attachment.

Gas automatics of Italian concern "SIT" and micro-slit low-flame burner "POLIDORO" are used in boilers.
Due to low hydraulic resistance it is also possible to work in open heating systems with a natural (gravitational) circulation of the coolant.
