WPF 20 / 27 / 35 / 40 / 52 / 66
- Geothermal hydronic heating for larger complexes
- 21.5 – 67.1 kW heating output at B0/W35
- Stackable design to maximise available space
- Cascade control for high output requirements
- High reliability through robust single compressor design
- Integrated heat and electricity meters
- Extremely quiet operation
Designed for residential and commercial complexes with larger heating loads, the stackable WPF range of geothermal hydronic heat pumps are a demonstration of the advancement of heat pump technology. Featuring cascade control which allows additional units to be started dependant on peak loads. Winner of multiple design awards, the WPF 20-66 geothermal heat pumps can be stacked to save space.
Geothermal heat pump for indoor or weatherproof outdoor installation. Suitable for multi-family houses and commercial applications due to up to 66 kW as a single device and up to 400 kW in a cascade. Optimized for space-saving set-up thanks to the stackability of 2 devices on top of each other.
EQUIPMENT / COMFORT
In order to minimize the transmission of structure-borne noise to the building, the cooling circuit is located on a vibration-decoupled base plate. The heat pump controller (accessory) in conjunction with the ISG (optional accessory) enables the system to be controlled in the home network or with a mobile device. With integrated heat and electricity metering via refrigeration circuit data. If necessary, the integration into a building automation can be realized via a software extension.
The heat pump unit is equipped with a scroll compressor with start-up relief and optimized heat exchangers to increase efficiency.
Internal pressure hoses enable a direct hydraulic connection to the heating and brine circuits. For the introduction in confined spaces, it is possible to reduce the basic device for transport to a width of <800 mm. There are also attachment points for crane lugs on the basic device.
