Ecocondens Crystal II Plus

 

ECOCONDENS CRYSTAL II PLUS gas condensing boilers are intended for heating small and large areas. Their characteristic feature is the ability to achieve a very wide range of modulation, e. g. thanks to the innovative BLUEJET burner, which allows to reduce the minimum power up to 3 kW. Stainless steel heat exchanger guarantees high energy efficiency and economical boiler operation. Control system enables comfortable remote control of the boiler by user and monitoring operation of the device by service personnel via laptop.
