Air-water heat pump current consumption and data

2021-02-02 10:32:47

Evaluated the last 24 hours today:

Outside temperature approx. 1 degree
Required heat quantity in the last 24 hours: 90 kWh (water and heating)
Electricity consumption: 24 kWh

90/24 = COP 3.75.

That’s not completely crazy now, but it’s also not really good for a KFW55 house with a state-of-the-art air heat pump. I would really like to be above 4.x.

I will carry out a new hydraulic balancing again when it gets colder, I think there is a short circuit there and thus unnecessary energy is being wasted.

But otherwise, everything is already optimized as far as possible.

24 kWh for the last 24 hours is really not good. I will reset my heat pump and also look at the next 24 hours again.
Yesterday I had 21.6 kWh overall for 24 hours.

That can no longer be explained by 2 degrees higher flow temperature and heating the basement.

is not good? :eek:

isn't it good? :eek:

What consumption did have yesterday?

No, in my opinion it is not good either. I would expect a value between 17 and 21 kwh. That means an efficiency increase of about 20%.

How are your Tacos set per HK? Have you already posted the table/data here?

No, that's exactly what I need to work on now. I am preparing a table a) theoretical calculation b) actual setting c) target condition And then I will recalibrate everything.
