WPC 10 S GB – Overview

  • High COP all year round enables low running costs
  • Easy and space-saving installation thanks to integral DHW cylinder and high level of integration
  • Extremely quiet operation thanks to multiple anti-vibration coupling
  • Easier handling through split design and handles
  • Flow temperatures up to 65 °C ensure high level of DHW convenience

APPLICATION: Compact brine | water heat pump for indoor installation with integral DHW cylinder and high level of integration. Can be used in mono mode to provide DHW and central heating in new builds and modernisation projects due to the high flow temperatures. The compact design requires only a very small floor area.
EQUIPMENT/CONVENIENCE: To minimise the transfer of structure-borne noise to the building, the refrigerant circuit is mounted on an anti-vibration mounting plate. The consistent source temperature guarantees unchanging heating output all year round, with flow temperatures up to 65 °C. The integral heat pump controller enables fully automated, weather-compensated control of the heating system and, when combined with the optional ISG, the ability to control the system via a home network or a mobile terminal device. With integral heat and electricity metering via refrigerant circuit data. One HE circulation pump and one expansion vessel are provided for the brine and heating sides respectively. An electric emergency/booster heater for mono mode operation and pasteurisation, a diverter valve for DHW heating and a safety valve with discharge hose are integrated as standard. The refrigerant circuit is hermetically sealed, tested for tightness at the factory and filled with safety refrigerant R410A.
EFFICIENCY: The heat pump drive unit is equipped with a scroll compressor with a soft starter and optimised heat exchangers for improved efficiency.
INSTALLATION: The supplied pressure hoses enable direct hydraulic connection to the heating side and source side. The metal casing is corrosion-protected and made from galvanised and powder-coated sheet steel, with an Alpine white stove enamel finish. To facilitate heat pump handling, the refrigerant circuit can be separated from the cylinder module with little effort. Carrying handles at the top and bottom make it easier to transport the appliance.

Comes with a FREE ISG Web Interface (Internet Service Gateway) – Allows communication with your heat pump remotely via a Smartphone Web app and also allows communication with the Stiebel Eltron Customer Service Centre.
