Viessmann Vitocal 150-A

Monobloc air-to-water heat pump for new builds and renovation: 2.1 – 14.9 kW, natural refrigerant R290, flow temperature up to 70 °C.

The Vitocal 150-A series are monobloc air-to-water heat pumps for space heating, cooling and domestic hot water. They come in two output classes: 2.1 to 8.0 kW and 2.6 to 14.9 kW. The compact units with outdoor units A4, A6 and A8 are designed for new builds. The more powerful unit with outdoor units A10, A13 and A16 reaches a flow temperature of 70 °C thanks to its well-designed refrigerant circuit with propane (R290) and is therefore also recommended for modernisation.

The natural refrigerant R290 has a GWP100 of only 0.02 (Climate Protect++). The patented Hydro AutoControl® hydraulics (OptiPerform) ensure reliable, highly efficient operation over the entire service life, save time and cost during installation and need up to 60 % less space than conventional systems. In the warm season the active cooling function provides pleasant room temperatures.

The Viessmann One Base electronics platform with a 7-inch colour touch display is operated directly on the unit or via the ViCare app. On request, the specialist partner can monitor the system remotely with ViGuide. Electricity from your own photovoltaic system makes operation even more economical.
