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.
- heat exchanger made of stainless steel
- wide range of modulation: from 11% to 100%
- high efficiency circulation pump
- stepless speed regulation fan (controlled electronically)
- cylinder burner made of stainless steel – low level of NOx emission (6th class)
- complete protection system
- optimization of boiler operation is possible due to application of:
- outdoor temperature sensor
- temperature regulator: ON/OFF, Open-Therm or 0-10V,
- ROUND system for remote boiler control via smartphone,
- EVOHOME system for remote control of up to 11 heating zones
- ready-to-use multi-zone modules for controlling up to 3 SIM heating systems
- boilers can also cooperate with:
- heat pumps air/water
- solar panels
