WPE-I 07.1 / 12.1 Plus H 230
- Geothermal heat pump for hot water and heating
- Year-round optimal operation and maximum efficiency thanks to inverter technology
- High flow temperatures of up to 75°C
- Future-proof and environmentally friendly refrigerant
- Quiet operation
- Optional integration into the home network and control via smartphone
Product Overview
This ground source heat pump with inverter technology is suitable for heating and optional cooling of family houses as well as for DHW heating. Thanks to the high flow temperatures all year round, the heat pump can be used in both new builds and modernisation. The system uses the natural and future-proof refrigerant R290 for optimum environmental compatibility. The heat pump can also be used for cooling with additional external components. Cascade operation is possible with up to 6 appliances.
Product Details
Convenience features
The heat pump in a design casing is installed indoors. The low space requirement in the installation room is achieved by the high level of integration: The compact enclosure 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). Intuitive operation via the easy-to-read, colour touchscreen display. Control with mobile devices is also possible via the MyStiebel app. 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. The heat pump can be operated without a buffer cylinder.
Efficiency
The inverter technology and speed-controlled circulation pumps ensure high efficiency and low follow-up costs. Optimisation according to dynamic electricity tariffs is possible.
Safety
Despite the use of R290, the sophisticated safety concept only requires a vent pipe to the outside. The safety fan is already integrated into the heat pump. The 80 mm core hole can be produced out by a qualified contractor without specialised knowledge. An accessory set with flexible pipe and wall outlet is available for easy connection of the heat pump to the vent pipe.
Installation
The heat pump is easy to transport to the installation site thanks to its low weight and ergonomic carrying concept. The sophisticated safety concept means that only one air duct to the outside is required. No additional electronics or cables are needed. The system's high level of integration enables quick and easy installation.
