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. High energy efficiency, convenient control via app, sustainable operation and attractive design are all convincing features.
Works well in combination with existing heating systems
The Vitocal 250-SH version is particularly suitable for supplementing an existing heating system. The heat pump provides the base load in that case. The boiler is only switched on at especially low temperatures.

Benefits of the Vitocal 250-SH
Climate Protect++ protects the environment and the climate
The new heat pumps in the Vitocal 250-SH series use the environmentally responsible refrigerant R32 with a low GWP100 (global warming potential) of 771.
Eco Select –– switch between the most cost effective or the most sustainable operating mode
Hybrid units from Viessmann use Hybrid Pro Control®. This integrated energy manager controls the heating system according to external conditions such as the outside temperature or flow temperature, and to suit individual user settings. These can be energy prices, the amount of self-generated power, CO2 emissions or the heat demand. Users can select, for example, whether the appliance automatically uses the currently cheapest energy source in economy mode. Or whether it runs in ecological mode with the lowest CO2 emissions per kilowatt hour of heating energy generated.
OptiPerform –– reliable operation with maximum efficiency
The advanced heat pumps from Viessmann work with a patented hydraulic system. With Hydro AutoControl®, the heat pump is operated reliably and with maximum efficiency throughout its entire service life. The unique design not only ensures that your contractor can set up the heat pump with OptiPerform much faster and, therefore, more cost effectively. It also takes up much less space because it is up to 60 percent smaller than comparable systems.
Super silent –– whisper-quiet in full and partial load operation
Viessmann heat pumps are among the quietest of their kind thanks to advanced acoustic design+, and include a sound-optimised fan. Combined with intelligent speed control, it significantly reduces airborne noise in both full and partial load operation. As a result, the outdoor unit can be installed even in densely built-up areas such as terraced housing or close to the property boundary.
