About Viessmann Heat Pumps
Viessmann Vitocal heat pumps use environmental energy to provide heating, cooling, and hot water without burning fuels like oil or gas, reducing resource consumption and carbon emissions. They draw energy from ambient air, groundwater, or the ground, and are available in five types: air source, ground source, and large heat pumps. Key features include high energy efficiency, app-based control, quiet operation, and compatibility with modernisation projects.
Key Features:
- Heating, Cooling, and DHW:
- Flow temperatures up to 70°C.
- Compatible with existing radiators and optional underfloor heating.
- Options for natural or active cooling.
- Sustainability and Efficiency:
- Combines with photovoltaic systems to power compressors and valves.
- High coefficient of performance (COP).
- Compact designs like the 222-G require less than half a square meter.
- Flexible Applications:
- Suitable for new builds, modernisation, residential, commercial, and local authority premises.
- Cascade functionality allows connection of multiple units, scaling up to 1450 kW.
- Quiet Operation:
- Sound-optimised, low vibration design enables installation close to living spaces.
- Advanced Models:
- Vitocal 350-G: High temperature for older buildings with radiator systems.
- Large heat pumps (e.g., Vitocal 300-G/-W Pro): Suitable for larger premises.
Viessmann Vitocal heat pumps offer an environmentally friendly and adaptable solution for heating and cooling needs, with scalable output to suit diverse applications.
