The Vitocal 252-A is a compact air source heat pump in the monoblock design with integral 190-liter DHW cylinder.
The new generation of heat pumps
Reliable, compact and more environmentally responsible than ever – the new, innovative heat pump technology from Viessmann makes particularly efficient use of environmental energy for heating and cooling. With a flow temperature of up to 70 °C, the Vitocal 252-A was specially developed for modernization projects. Existing radiators can continue to be used. Underfloor heating is not essential. High energy efficiency, convenient control via app, sustainable operation and attractive design are all convincing features.
Features an integrated Vitotronic control system for intuitive, centralised control of:
Heating
Cooling
Domestic hot water (DHW)
Energy management functions
Simple and intuitive system operation via the ViCare app, providing clear system status, temperature control, and energy insights.
Designed for digital connectivity, enabling remote monitoring, control, and service access through Viessmann’s digital ecosystem.
Prepared for optimised use of self‑generated electricity from PV systems, reducing grid dependency and improving sustainability.
