Brine/water heat pump WWP S series

class A+++energy savinghigh-temperature

Presentation
The Weishaupt brine-to-water heat pumps (WWP S) recover subsurface heat for heating and cooling. Quiet, efficient systems suitable for a wide range of building types, with available models covering a broad power range (approximately 6 to 130 kW depending on configuration).

Main features

• Energy source: geothermal heat via a brine (glycol) / water circuit.
• High efficiency: can deliver up to about 5 kW of thermal energy per 1 kW of electrical input (performance coefficients among the best on the market).
• Complete supply: components sized and coordinated (class A circulator, room thermostat, possibility of geothermal drilling and connection up to the building boundary).
• Full production: heating and domestic hot water production (multifunction WKS cylinder available for compact integration of DHW cylinder, buffer tank and connection components).
• Power range: multiple versions covering domestic and commercial needs (examples of models listed below).
• High-temperature variants for retrofit: some versions permit flow temperatures up to 70 °C.
• Quiet operation: structural noise decoupling, acoustic insulation of the casing and low-noise, low-vibration compressors.
• Cooling: possibility of cooling (passive summer cooling using the subsurface constant temperature and using the heating circuit as a cooling circuit).
• Durability: materials and construction designed for extended service life.
• Easy control: integrated controller with plain-text menus for straightforward system adjustment.
• Funding eligibility: high performance enabling eligibility for public incentives depending on national schemes.

Labels and options

• EHPA quality label.
• SG Ready functionality for connection to future smart electricity networks.
• Combined offer: heat pump + geoplus® probe from Weishaupt.
