Despite the heat pump, wall boxes for electric car and home equipment, my photovoltaic system (PV) sometimes provides extra energy in summer. To use this wisely, I have a warm water tank ignoring – which is normally set to 49 ° C – with sufficient sunlight 55 ° C (with 55 ° C (the economic system limit of my device). Therefore, I do not have to heat water even when used in the evening. Since my heating system uses a freshwater station, there is no problem with Legieonela.

I use a raspberry pie, doker, portner, eobroker, EVCC (electric vehicle charge controller) and cointer. In this article I describe the most important stages with which you can rebuild the project yourself and provide configuration AIDS In project project Disappointment.
- Use photovoltaic surplus wisely
- Save energy in the form of warm water for the evening
- Include heat pump using Iobroker in EVCC
However, due to complexity, the article suggests that you familiarize yourself with the system used and read the interface details of your hardware. Not at least because every smart house has other conditions that require personal adjustment.
This was the reading sample of our hes-plus article “Heat Pump-Hac: How to use additional solar energy in summer”. With a heise plus membership you can read and hear the entire article.
