GEO Thermal - Vitocal 350

Brine/water heat pump rated from 11.0 to 17.1 kW, water/water heat pump rated from 14.1 to 20.0 kW, flow temperatures up to 65 °C

Even if you modernize your home you need not do without the environmentally friendly and costsaving energy of a heat pump. The Vitocal 350 reaches a flow temperature of up to 65 °C and is thus also eminently suitable for modernization projects.

Modernization made easy

Older buildings are often equipped with radiators which are to be retained during modernization. Radiators do, however, need higher flow temperatures than underfloor heating systems. Not a problem due to Viessmann’s innovative technology. With an additional steam injection point (EVI cycle) in the compressor circuit, the Vitocal 350 heat pump reaches a flow temperature of up to 65 °C.

Higher flow temperature for a high level of hot water comfort

The higher flow temperature means that the temperature of the water in the DHW cylinder can be as high as 58 °C, depending on the system configuration. This allows the Vitocal 350 to offer a particularly high level of drinking water comfort.

Heating comfort throughout the year

The efficiency of the Vitocal 350 heat pump makes it a powerful, capable and complete heat provider. It can – throughout the entire year – supply all of the energy needed for heating and hot water, doing so in monovalent operation – in other words, without support from another heating system, even when air is the energy supplier.

Cooling and heating

Particularly pleasant on hot days: with the integrated “Natural Cooling” function (with special accessories) the low temperatures in the ground or groundwater can be used for cooling.
