Ground source heat pumps

WPE-I 12.1 Plus H 230 PACK 2

Application • Combines our R290 ground source heat pump with a light-weight stainless steel DHW cylinder and separate buffer tank. Making it ideal for installations with higher hot water demand. • Integrated, tried, and tested quality components maximise the systems efficiency, and saves you valuable time on site. Intuitive operation via the easy-to-read colour touchscreen. Online monitoring and control with mobile devices via the MyStiebel app.

The ground source heat pump with inverter technology is suitable for heating, optional cooling and for DHW heating. • Thanks to the high flow temperatures all year round, the heat pump can be used in both new build and modernisation. • Controls are suitable for integration with PV, smart tariffs and demand side response. • The system uses the natural and futureproof refrigerant R290 for optimum environmental compatibility. • The heat pump can also be used for cooling with additional external components.

Convenience features • The heat pump in a design casing is installed indoors. • The low space requirement is achieved by the high level of integration: inside the compact casing, the unit is equipped as standard with a controller and hydraulic components such as a diverter valve, circulation pumps (source and sink), electric emergency/auxiliary heater and safety valves (source and sink). • The heat pump is very quiet in operation as the refrigerant circuit is mounted on an anti-vibration base plate. This minimises the transfer of structure-borne sound to the building. • Active cooling is possible through external circuit reversal; for passive cooling an additional external plate heat exchanger is required.

Efficiency • The inverter technology and variable speed circulation pumps ensure high efficiency and low subsequent costs. • Optimisation using dynamic electricity tariffs.

Safety • The sophisticated safety features require only one vent pipe to the outside, despite the use of R290. The safety fan is already integrated into the heat pump. The core hole of 80 mm can be drilled by a qualified contractor without specialised knowledge. • Accessory set with flexible pipe and wall outlet for simple connection of the heat pump to the vent pipe.

Installation • The heat pump is easy to transport to the installation site due to its low weight and ergonomic design. • Thanks to the sophisticated safety features, only one air duct to the outside is required. No additional electronics or cables are required. • The system's high level of integration means that installation is quick and easy.
