Characteristics
Wall-mounted condensing boiler without secondary heat exchanger for direct production of domestic hot water
Can be connected to all VIH indirectly heated water heaters and allSTOR multipurpose storage tanks
Tested efficiency up to 109%
Possibility of operation with LPG after conversion
Equipment
Complete system with 10lt expansion tank, three-way for the production of DHW through an indirectly heated water heater (not included in 466, 656, 806, 1006, 1206)
eBUS system
LCD display for indications of control function - failure
Automatic inverter circulator (automatic two-stage for the 466, 656)
ELGA gas valve for optimal combustion air ratio control (Pneumatic gas valve for 466, 656, 806, 1006, 1206)
Energy Labeling
Space heating energy efficiency: A
Observations
The ecoTEC VU PLUS 656 wall-mounted boiler may not be operated with LPG.
In the wall-mounted boilers ecoTEC VU PLUS 466 and ecoTEC VU PLUS 656 it is necessary to install a 2nd circulator with a mixer in the heating circuit, as well as a circulator for connection to an indirectly heated VIH boiler.
The wall-mounted boilers ecoTEC VU PLUS 376, ecoTEC VU PLUS 466 and ecoTEC VU PLUS 656 do not include an expansion tank and a safety valve.
The installer must install an expansion tank and safety valve externally.
