EFFECTIVE ECOTEC HEATING-ONLY CONDENSING BOILERS BY VAILLANT
Possibility of connection with an indirectly heated water heater VIH.
Special features
Wall-mounted condensing boiler without secondary exchanger, 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 screen 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).
Remarks:
The installer must install an expansion tank and safety valve externally.
In the wall-mounted boilers 806, 1006 and 1206 it is necessary to install a 2nd circulator together with a plate heat exchanger or thermal separator depending on the hardness of the installation water.
