How else? The heat pump only ran for 146 minutes in 24 hours. Yet the house is warm enough.
If the heat isn’t coming from the heating system, there must be another source. The only things I can think of are fire, the sun, or friction heat. What are you all doing during the lockdown? 😀

Friction heat :-p. That was a good one.
The sun won’t be out again until tomorrow.

Summary for January:

Novela ladv 9-hsdv
156 m² (1,680 sq ft) living area
Controlled mechanical ventilation: level 2 from 7 a.m. to 8 p.m.; level 1 from 8 p.m. to 7 a.m.
Outdoor temperature ranged between -1°C and +7°C (30°F and 45°F)
Indoor temperature set to 23°C (73°F) throughout the house
All actuators fully open
One meter for household and heat pump electricity

Total consumption was 730 kWh
Average daily consumption = 18 kWh

This is acceptable... could be a bit more efficient

How much heat energy has your house absorbed during this period?

Novela ladv 9-hsdv
156 m² (1,679 sq ft) living area
Controlled residential ventilation: Level 2 from 7 a.m. to 8 p.m.; Level 1 from 8 p.m. to 7 a.m.
Outdoor temperature ranged between -1 to +7°C (30°F to 45°F)
Indoor temperature maintained at 23°C (73°F) throughout the house.
All actuators fully open.
One meter for household and heat pump electricity

Total consumption was 730 kWh
Daily average = 18 kWh

That’s okay... could be a little better


So, the 18 kWh includes heating and hot water? Then it performs similarly mediocre to mine, considering living area and outdoor temperature. But it’s also a Novelan, so it’s no surprise. They’re not efficiency miracles.
