Effective management of domestic hot water heating using photovoltaics
Talajka, Martin ; Zachariáš, Michal (referee) ; Materna, Zdeněk (advisor)
This work solves the problem of efficient control of water heating using photovoltaic system. To solve the chosen problem, I designed an algorithm and implemented it in the form of integration into the Home Assistant system, which also serves as a central control device. And it provides the integration between the boiler and the PV system. Thanks to this integration, it is possible to automatically and comfortably heat water from the surplus energy of the photovoltaic system, or alternatively from batteries or the distribution network. At the same time, system status monitoring and remote device management are possible. For example, the user can monitor the temperature of the heated water, the status of the overall system, adjust the heating temperature or set the water heating for a specific time, using an app or a web interface. The results of the work show that the proposed system is easy to use and is able to efficiently manage the water heating using the PV system, thus saving energy and gas.
