The new Weishaupt WWP LS K compact split heat pump is available with an 8 or 10 kW output. The newly developed indoor unit with an integrated 165-litre cylinder and all of the necessary hydraulic components saves on space and is easy to bring in and install.
The ability to decouple the hydraulic unit and cylinder, so that they can be easily carried through separately into areas with limited access, is particularly advantageous.
The units are notable for their high performance factor. Additionally, they are quiet and, thanks to their intuitive controls, easy to operate. Both the quiet running and the dynamic cooling are possible with the hiqh-quality standard equipment. If desired, the new Weishaupt app enables the heating system to be controlled just by a smart phone or tablet.
Electronic BiFlow expansion valve
The electronic BiFlow expansion valve with 490 stages and electronic fast start (≈2 min.) also provides increased efficiency. There is a single valve for heating, cooling, or defrosting.
The outdoor unit has an evaporator with a special BlueFin coating for increased protection against corrosion and less dirt retention. The pearl effect results in improved defrosting. The defrosting function is self-learning.
Double rotating piston compressor
The double rotating piston compressor with quick-response inverter ensures exceptionally quiet operation, rapid achievement of setpoints, and impressive durability. It is equipped with high-quality, noise-suppressing thermal insulation and has sound-insulated bearings.
The fan's energy-saving brushless motor guarantees high efficiency and durability. The shape of the fan blades is aerodynamically optimised for large air volumes.
A special silent mode throttles the fan speed during a freely definable period (e.g. overnight) so that the split heat pump operates even more quietly. This does not impair the basic heat supply.
Condensate tray without electric heating
Condensate is drained away via precisely positioned holes, guaranteeing reliable operation down to -20 °C. This obviates the need for electric heating and its associated power consumption.
Hydraulic unit – heating components
The hydraulic unit (indoor unit) contains, as standard: Condenser with diffusion-resistant insulation, expansion tank, safety set with venting system, sludge separating system, high-efficiency circulation pump (Energy Class A) for heating and DHW with leakproof three-way valve.
Hydraulic unit – electric components
The hydraulic unit contains the following electric components: Second heat generator for heating and DHW, volume flow sensor, flow and return sensors, LED function bar and system control unit with high-quality colour display.
Simple, intuitive control
The new controller with colour display follows Weishaupt's proven "press and turn" principles. Thanks to the commissioning assistant, these have been considerably simplified and shortened. Setpoints are retrieved via clear-text messages.
Easy operation via app or browser
Thanks to the new Weishaupt app and the Weishaupt Energy Management Portal, the new compact split heat pump can communicate and be controlled easily and securely over the internet with computers, smartphones, or tablets. Alternatively, the heat pump can also be controlled by an optional room controller.
Cooling as standard
Both quiet running and dynamic cooling are possible with the hiqh-quality standard equipment.
Flexible connection options
Heating, DHW, and circulation can be connected from the left or right-hand sides or from above as required.
WAS 165 Eco cylinder
The 165-litre WAS Eco DHW cylinder is equipped with an efficient, 1.7 m2 coiled tube heat exchanger. New composite thermal insulation with vacuum insulation panel (VIP) ensures minimal standby losses.
