Features

• Wall-mounted condensing boiler without secondary heat exchanger for instant hot water production
• Ability to connect with all indirectly heated water heaters VIH and multi-purpose storage tanks allSTOR
• Tested efficiency up to 109%
• Ability to operate with LPG after conversion

Equipment

• Integrated system with 10lt expansion tank, three-way valve for hot water production through indirectly heated water heater (not included in 466, 656, 806, 1006, 1206)
• eBUS system
• LCD display for operation control – fault indications
• Automatic inverter circulator (automatic two-stage for 466, 656)

Notes

• The wall-mounted boiler ecoTEC VU PLUS 656 is not allowed to operate with LPG.
• For the wall-mounted boilers ecoTEC VU PLUS 466 and ecoTEC VU PLUS 656, the installation of a second circulator with a mixer in the heating circuit, as well as a circulator for connection with an indirectly heated VIH boiler, is required.
• The wall-mounted boilers ecoTEC VU PLUS 376, ecoTEC VU PLUS 466, and ecoTEC VU PLUS 656 do not include an expansion tank and safety valve. The installer must place an external expansion tank and a safety valve.
• For the wall-mounted boilers 806, 1006, and 1206, the installation of a second circulator along with a plate heat exchanger or thermal separator is required, depending on the hardness of the installation water.
