Ecocondens Silver Plus
Gas condensing boilers line ECOCONDENS SILVER PLUS – 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.

Boiler Overview
- energy class: A
- Easily convertible from COMBI to LPG by simple settings change
- heat exchanger with one coil made of stainless steel
- wide modulation range: from 12 to 100%
- electronically controlled modulating fan
- cylinder burner made of stainless steel – low level of NOx emission (6th class)
- domestic hot water cylinder by 3-way valve (refers to system boilers)
- hydraulic group (hydroblock) assembled on quick-connector
- complete protection system
- additional noise insulation provides quiet operation of the boiler (only 48 dB)
- 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
- domestic hot water cylinder by 3-way valve (concerns system boilers)
- possibility of remote monitoring of the boiler by service technician (LIN system)
