In summary it appears to be a heat pump that stores heat during the day /warmer temperatures and releases it when needed. This could work well with a number of time of use power schemes (in addition to people with solar); charge up mid day for the late afternoon peak demand, off from 4pm - 8pm, maybe charge up middle of the night when power is cheap for the morning setback recovery or shower?

    Kinda neat, but isn't 2.5 kWh about the same as running a 100 watt light bub for a day? For the quoted 7500 € that seems like a poor investment. Plus, it's metric…

    Yea, at 2.5kwh it's basically useless unless you have a passive house... That's about 5 minutes of run time with my boiler.
