Vitocal 300-A - efficient and stylish

Benefit from these advantages

  • Air-to-water heat pump in modern design
  • Low electricity costs during operation
  • Prepared for connection of a photovoltaic system
  • Comfortable domestic hot water heating due to high performance
  • Easy operation via mobile devices such as smartphone and tablet
  • Energy efficiency class*: A++
*for low temperature application (35 °C)

Solar power reduces operating costs

The Vitocal 300-A air/water heat pump is a real eye-catcher. It is installed in the garden and uses the free heat of the ambient air. The unit is especially designed for modernizing single-family homes.

Even in normal operation, Vitocal 300-A is very quiet. At night, the fan noise is further reduced by a low speed.

Electricity from a dedicated photovoltaic system can be used to operate the electrical components, reducing the already low operating costs.

Simply cool in summer

The Vitocal 300-A is already prepared for reversible operation to cool rooms during the warm season.

Convectors or surface cooling systems then create a comfortable indoor climate at high summer temperatures.

Coordinated with each other: systems engineering

"The whole is greater than the sum of its parts." In line with this principle, Viessmann not only offers individual heating components that meet the high Viessmann standards in terms of quality, reliability and effectiveness. Rather, all products are integrated into a coordinated complete system in which all components fit together exactly. Because only the perfect interaction of system-integrated components exploits the full performance potential of innovative, cutting-edge technology.

Viessmann system technology includes everything that makes a reliable and economical heating system. The Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for optimum DHW convenience, and high-quality solar thermal systems for cost-saving central heating backup.
