ᐅ Air-to-Water Heat Pump: Current Consumption and Data

HarvSpec schrieb:

We are 3 people, living in a renovated 1960s house with 180m² (1,938 sq ft) of living space. The living room temperature is kept at 22–23°C (72–73°F), and the bathroom at least 23°C (73°F). Our current energy consumption is around 11–12.5 kWh per day. With an average outdoor temperature of about 5°C (41°F) in the evening, the stove is often on.

Sorry, but if I’m basically heating the bathroom separately, living with the stove on, and the other rooms probably staying cold, then I can disregard those consumption figures. No input means no output.

I currently use more than twice the energy to reach 22°C (72°F) in the living area and 23.5°C (74°F) in the bathroom, with an outdoor temperature around 2°C (36°F), including hot water.

But you're doing this on purpose, right? 😉

Absolute figures without real points of comparison are actually quite pointless. Therefore, an attempt at standardization. In our heating load calculation, this information can be found (referring to the entire house):

Currently, we have an average daily temperature difference of about 22°C (about 0°C outside, 22°C inside), which corresponds to a current heating load of 2,860 W. Applying our current COP to this matches quite well.

Do you have this information too, and does it match your situation?

Just took a quick look: in November it was 391 kWh, so roughly 13 kWh per day for the entire system. Room temperature 22-23°C (72-73°F), KWF55 standard, 218 m² (2347 ft²) heated area.

It's good if you see it that way, but some others are interested in the supply temperature and how consumption figures look when there is more than one heat source.
Bathroom electricity consumption per day is about 0.75-1.05 kWh, I’m not weighing the wood now. The other rooms are, by the way, kept at 20-22°C (68-72°F). Especially in older buildings with a few thermal bridges, the requirements can be somewhat different.
