REMKO WKF-COMPACT SERIES Air/water system for heating and cooling

The compact class saves space and installation effort

WKF-compact series does not require a large mounting area due to its compact construction and integrated components. In connection with underfloor heating, this unit is perfectly suited for new buildings. This construction saves space in the mounting area. The costs for installation are reduced by the high percentage of premounted components.

Profit from these advantages

  • Low investment costs
  • Power-modulated operation due to modern inverter mode
  • Low operating costs due to high COP value
  • Ready for connection of solar system to drinking water supply
  • Mounting-friendly installation
  • High hot-water comfort due to integrated, enamelled domestic water tank WKT 300 with a volume of 300 litres
  • Extremely low heating losses of the WKT 300 domestic water tank
    BEVB 1,19 kWh/day
  • Electric booster heating 49 W
  • Smart-Control intelligent control system 
    Use in intelligent smart-Grid power mains possible
  • Integrated heating circuit pump for the supply of the heating system
  • Integrated electronic bypass valve for guraranteeing the minimum volume flow rate
  • Intelligent thawing logic circuit
  • Monoenergetic operation possible through REMKO smart-Serv or bivalent operation possible through REMKO Smart-BVT
  • Night operation to reduce noise
  • WI-FI ready

Scope of supply

  • REMKO Smart-Control Touch - the intelligent control system
  • Indoor unit with integrated domestic water tank WKT 300 (300 litres)
