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

It also affects my diet negatively; mostly hot soups have ended up on the lunch menu ever since.

I’ll put it this way: I sympathize with you, but only to a limited extent.
With such an irresponsible action on your part, you should be grateful you’re not restricted to bread and water until the bathroom reaches 24°C (75°F) again and the rest of the house returns to a comfortable temperature. The latter created by frictional heat when you crawl around the house on your knees before the authorities! 😉

I am a bit speechless when I read that 20.9 degrees Celsius (69.6°F) is considered the end of the world. Well, everyone gets what they deserve 😎 and chooses for themselves :p

For us, it's already doomsday below 23°C (73°F) :p
Had a lawyer check it, it was actually in the fine print at the wedding ceremony 🙂

We have temperatures between 23-24°C (73-75°F) in the bathroom and around 22-23°C (72-73°F) in all other rooms.

The compressor outside has now been running continuously for 3 days without shutting off once. The outdoor temperature averages 6°C (43°F) over 24 hours.

Yesterday, we checked our values. From mid-October to mid-March, our electricity consumption is about 2200 kWh, which generated approximately 9400 kWh of heat (heating + hot water), resulting in an efficiency factor of around 4.25. If I also include the transitional periods and hot water consumption in summer, the annual consumption comes to about 2800-2900 kWh. Roughly 12-15% of this is produced by the photovoltaic system.

I’m very satisfied; the winter was noticeably colder compared to recent years.

Your heat pump seems to be a perfect fit. Mine doesn’t go down that far. Currently, it usually runs about 10-12 hours on and 10-12 hours off. The hysteresis is only 1°C (2°F).

From mid-October to mid-March, we use about 2200 kWh of electricity, which produces around 9400 kWh of heat (heating + domestic hot water), resulting in a seasonal coefficient of performance (COP) of approximately 4.25. Including the transitional periods and summer hot water, our annual electricity consumption comes to about 2800–2900 kWh. Roughly 12–15% of that is produced by the photovoltaic system.

Your heat pump seems to be a very good fit. Mine doesn’t get as efficient. At the moment, it usually runs for 10–12 hours on and 10–12 hours off, with a hysteresis of only 1°C (34°F).

For that period, our electricity consumption is around 3300 kWh.

@above: I find 23 to 24 degrees Celsius (73 to 75°F) uncomfortable; I don’t even want that temperature inside the house during summer. We consider 22°C (72°F) ideal.
