Gas condensing boilers line SILVER PRO – one of the most modern and smallest devices in the European market. Thanks to transparent control panel these boilers are very easy to use. Advanced design and compact sizes make them fit in every kitchen and other rooms as well. Wide range of modulation allows the boilers to heat very small areas and objects with low heat demand. Devices are adapted to work with solar systems, heat pumps and multi-zone hydraulic separators.
- energy class: A
- heat exchanger with one coil made of stainless steel
- wide modulation range: from 12 to 100%
- OPEN-THERM system by EASY REMOTE regulator
- electronically controlled modulating fan
- cylinder burner made of stainless steel – low level of NOx emission (class 6)
- hydraulic group (hydroblock) assembled on quick-connector
- complete protection system
- works with multi-zone hydraulic separators for heating systems
- works with heat pumps air/water
- additional noise insulation provides quiet operation of the boiler (only 48 dB)
- works with solar panels
- high efficiency circulation pump
