Description
APPLICATION:
Hot water heat pump in compact design for efficient hot water supply of several withdrawal points. For recirculation or air duct operation, as well as for use at low air intake temperatures. High flexibility in installation/installation in the installation room through free choice of air duct (side and/or top with accessories).
FEATURES / COMFORT:
Very high warm water comfort. Maximum spigot profile XL, nominal spigot profile L. Up to 65°C in pure heat pump operation for hygienic hot water preparation as well as very high mixed water quantities. High usage comfort: Electronic regulator with LC-display and display of the currently available mixed water quantity. Quiet operation through the air flow of sound-insulated compressors. Very compact 220L design, ideal for exhibition rooms with low ceiling height. Highest security and cost savings through integrated external current anode.
COMBINATION:
Intelligent interface for communication with suitable photovoltaic systems as standard (for a targeted increase in own consumption).
EFFICIENCY:
Outstanding efficiency. All devices of the series are characterized by their classification in the highest possible energy efficiency class A. Spring-loaded Rollbond heat exchanger for maximum safety and long-term high efficiency in operation.
