Water/water heat pump WWP W series

ground/waterbrine/waterhigh-temperature

Overview
Weishaupt water-to-water heat pumps draw energy from groundwater. Groundwater provides a highly stable source temperature, which improves system efficiency. Designed for robustness, Weishaupt WWP W units can operate with a wide range of water qualities. Available powers range from 10 to 180 kW, enabling heating and cooling for diverse building types.

Main benefits

• Energy source: groundwater utilisation with stable source temperature for excellent efficiency.
• Complete system offer: perfectly coordinated components (A-class circulator, room thermostat, etc.).
• Full delivery: heating production and domestic hot water preparation via multifunction WKS module (integrates DHW heater, buffer tank and connection components).
• Quiet operation: structure-borne noise decoupling, acoustic insulation of the casing and low-noise, low-vibration compressors.
• Application versatility: power range 10–180 kW; high-temperature models available (supply up to 70 °C) for renovations without underfloor heating or boiler replacements.
• Cooling capability: active and passive cooling modes using the groundwater’s low, stable temperature.
• Extended service life: selected materials and robust design; for units ≥35 kW, groundwater analysis is recommended.

Additional information
With approx. 1 kW of electrical input, glycol-water variants of Weishaupt units can deliver up to 5.5 kW of thermal energy (high COP). The integrated controller offers straightforward operation via clear text displays. Weishaupt heat pumps carry the EHPA quality label and are SG Ready for future smart grid integration. Their high efficiency makes them eligible for financial incentives.
