Advantages of Vitocal 250-A

Climate Protect+++
OptiPerform
Service Link
Super Silent

Climate Protect+++ protects the environment and the climate

The new heat pumps in the Vitocal 25x series use the “green” refrigerant R290 (propane), which is considered particularly environmentally responsible due to its very low GWP100 (Global Warming Potential) of 0.02.

OptiPerform – reliable performance with maximum efficiency

Viessmann’s advanced heat pumps work with a patented hydraulic system. Thanks to the Hydro AutoControl® system, the heat pump operates reliably and with maximum efficiency over its entire service life. The unique design not only ensures that your contractor can install a heat pump with OptiPerform much faster and therefore more cost-effective. It also takes up much less space, as it is 60 percent smaller than similar systems.

Service link – fast response time for the service team

Service-coupled heat pumps use wireless technology to automatically notify the trading partner of possible faults. Completely free. This eliminates unnecessary travel as on-site service is faster. Save time and money.

Super Quiet – Quiet Whispers When Operating At Full And Part Load

Viessmann heat pumps are among the quietest of their kind thanks to their advanced acoustic design+ and feature a sound-optimised fan. In combination with intelligent speed control, it significantly reduces the noise level in the air at both full and partial load. As a result, the outdoor unit can be installed even in areas of dense development, for example, in terraced houses or near the border of the site.
