Air/water heat pump WEB series

propane (R290)high-temperatureinverter

Overview
The Weishaupt Evoblock® air-to-water heat pump uses outdoor air energy for heating, cooling and domestic hot water production. Compact monobloc design installed outdoors integrating all main components. Available in multiple power sizes to suit a wide range of buildings.

Key benefits

• High energy performance: from 1 kW electrical input, an Evoblock® can deliver up to five times more heating energy.
• Very low sound levels: optimized acoustic design and purpose-developed fan, low noise (43 dB(A) for WEB 07/10 models).
• Natural refrigerant: R290 (propane) with GWP = 0.02, environmentally friendly.
• Monobloc concept: all main components integrated in one outdoor unit; indoors only control and hydraulic components (including DHW elements) are installed.
• Suitable for renovation: Inverter technology and optimized refrigerant circuit deliver efficient performance at low outdoor temperatures; supply temperature up to 75 °C, compatible with radiators.
• Complete solution: supports domestic hot water production with modular buffer/DHW module (WMS).
• HEMS compatibility: Modbus/TCP connection to optimize photovoltaic electricity use (energy management).
• Intuitive control: color display regulation with simple navigation; accessible via app or web browser (WEM portal). Promotional offer: purchase an Evoblock® before 31 December 2026 to receive 5 years free access to the WEM Portal.

Functions

• Heating
• Cooling
