Viessmann Energy Management conserves resources, saves costs and optimizes the operation of the energy system. In addition to the heat pump, other connected devices such as power storage, DHW cylinder and the wallbox for the electric car are included.
Viessmann Energy Management is designed to ensure the maximum use of self-generated electricity and optimizes the interaction between the photovoltaic system and the Vitocharge VX3 electricity storage system with the Vitocal heat pump and the electric vehicle charging station. This reduces energy costs and is the best way to help protect the environment.
Make the most of your self-generated electricity
The Vitocal heat pump and the Vitocharge electricity storage system – the one thing that all system components have in common is the Viessmann One Base platform. It allows the control systems of these devices to make ideal use of the Energy Management system to ensure efficient operation. The Energy Management system also works with the connected Vitocal heat pumps that have been manufactured after November 2017.
The weather-based battery charging management system, which covers the electricity storage system, the heat pump and the wallbox for the electric car, ensures optimum control of the PV yield so as to achieve high levels of self-consumption. Devices in the house that require power (e.g., the heat pump or wallbox) can be switched on or off via the Viessmann Energy Management system in a flexible manner. Depending on availability, these devices use electricity from the Vitocharge electricity storage system. Optimizing PV self-consumption also allows surplus electricity to be converted, for example, into heat to heat the hot water cylinder or – depending on the configuration – to heat the building. Smart management allows users to benefit from a high level of user comfort and reduced energy costs.
All energy flows at a glance
Energy Management is integrated into the ViCare app on the users’ smartphones or tablets and displays energy flows in the building in real-time. This information includes, for example, figures on self-generated electricity from the Vitovolt PV system or from the Vitocharge VX3 electricity storage system, or data on the CO2 emissions saved. This gives users access to an intuitive and convenient energy cockpit at no cost.
Connecting existing PV systems with heat pumps
Thanks to the Solar-Log gateway, it will soon be possible to connect existing PV systems with Viessmann One Base. The gateway allows Viessmann One Base to recognize third-party components in the system and include them in the calculations for the Energy Management system. This means, for example, that Viessmann heat pumps can be supplied with self-generated PV power from other manufacturers’ products.
