In the last 24 hours, 48.8 kWh of heat was produced for heating and hot water.
Outdoor temperature ranged from 1 to -13.2°C (34 to 8°F), average temperature -6.4°C (21.5°F).
We had a lot of solar heat in the house from morning until evening today.

This confirms my consumption. Thanks.
It’s not just a few hours of solar gains.

For us, solar energy did not make any difference in consumption. We still required 140 kWh for heating and 45 kWh for electricity.

That can’t be right.
We have full-power sunshine here, and currently 27.1 degrees Celsius (81.8°F) on the ground floor, even though the thermometer is not in direct sunlight.

It is currently 23°C (73°F) on the ground floor, the sun is still in the east, and only a little sunlight is entering the house. However, I am surprised that it doesn’t make any difference at all...

In the living room, we have patio doors facing east as well as windows to the south and west. This allows us to catch the first rays of sunlight early in the day.

We already have the external venetian blinds lowered because it simply gets too hot from the sun. The entire ground floor was already at 26°C (79°F) early this morning.
