Gas or air heat pump experiences?

Well, I found the connections between economy/government quite interesting. Sure, some things might be poorly researched, but you shouldn’t start from the standpoint that everything presented to the average German has to be really good. See, very recently, the nonsense with the E-car subsidy.

I have also read the article in [Welt]. It is just one example. But also one of many. If you look at the consumption of some in the heat pump consumption database, you will find many values above 10,000KW.

They really messed up with their concept at the beginning. The consumptions are collected - even the biggest outlier uses 4300 kWh of electricity annually for heating and hot water - 90 € per month is still bad for a relatively new house... but where these horror numbers come from? Of course, if you install an air-water heat pump in an old building, you can't be surprised. I took the trouble to check and exactly... the highest I found is 6111 kWh of electricity with an air-water heat pump with a COP of 1.5... unclear where the 10 kWh in your case come from.

I have also read the article in Die Welt. It's just one example. But also one of many. If you look at the consumption of some in the heat pump consumption database, you will find many values above 10,000KW..

Which house, please, has a heat demand of 10 megawatts???

I have read about the consumptions from users in the "Rosa" forum... I can’t really provide a link now. But you can also find the outliers in the heat pump database.

If you scroll through it, you will find some with values of 7000, 9000, 11,000, etc. Of course, some also run in combination with radiators – that’s clear. But this also shows how sensitive the system is and that during planning one must be meticulously precise about the correct sizing and hydraulic balancing. You should not have a heat pump installed by someone who has no knowledge of it.
