Viessmann’s new controls allow solar PV and heat pumps systems to work together

Viessmann has launched a new feature on its Vitotronic 200 control system, which uniquely allows heat pump and solar PV systems to work as a hybrid system. From the heat pump deciding how to use free energy from the solar PV, electricity bills are significantly reduced. The controls allow the heat pump to monitor the electricity generated by the solar PV for sufficient generation over a consistent period of time, and then bring on the heat pump and utilise the free energy rather than returning it to the grid. This means that during these periods, the heat pump is able to operate at no
