Our electricity consumption is always very high on Saturday at 5 and 6:00. No machines are working at that time and we still haven't turned on our heating, which wouldn't be on at that hour anyway. Obviously we are also still asleep at that time. It was already like this in September and August, when our digital meter was installed. Weekend price starts on Friday 21:00 so I don't think it can be that either. We do have a heat pump so I'm thinking it works very hard for some reason every Saturday morning, but I have searched on our thermostat and couldn't find any settings for this. Any idea what else it could be?

  1. Heat pump deicing cycle? maybe a bit early for that but that could be it on a cold day

  2. Legionella protection if the heat pump also heats the water you use to shower etc.

  3. >> working very hard

    A heat pump at 2kwh isn’t even working hard. You probably have a schedule set for heating / warm water

  4. Its probably the anti-legionella program of you heatpump. It ran here in the middle of the night too and I scheduled it every Wednesday at 11:30 so it uses as much electricity from our solar panels.

  5. I mean the best way to single it out is to wake up before the CV does at 6am apparently and just listen if it starts working.
