Construction costs are currently skyrocketing

I'm curious to what extent the technology will develop further. Just today, I read again in a widely distributed home building magazine an article with the note "But precisely the air heat pump has a decisive disadvantage: the noise." The article is from 04/19/2022, and I thought in the meantime that the noise problem had been resolved (this is also communicated frequently here in the forum). I hope so, because if they become mandatory, it could be unpleasant if the noise problem is not solved. Especially since some owners might want to skip regular maintenance over time for cost reasons.

The technology will not develop further. It has existed for over 50 years (as a heat pump). As a refrigerator since the mid-19th century. And noise is relative. Mine is also very quiet — except when it heats up to 60 degrees supply temperature for hot water.
Apart from that, they only make "noise" in winter anyway, when you are inside the house with closed windows. And ground-source heat pumps are not heard at all.

One should rather be concerned about electricity consumption if everyone switches to heat pumps and also has an electric car in the garage.

Fear should be caused by the electricity price.

I have experienced that currently the local suppliers are really cheap. Green electricity with us is 33.26 cents (still with the old Renewable Energy Act surcharge) for one year or 32.76 cents as basic supply.

I have found that currently the local providers are really cheap. Green power with us 33.26 cents (still with the old Renewable Energy Act surcharge) for one year or 32.76 cents as basic supply.

I am in the basic supply for 30.6 cents. But they will probably adjust it soon. Fixed rate until the end of 2022 for 37 cents. Fixed for 2 years would of course have been great.

The new LWWärmepumpen are really almost whisper-quiet.

Besides, they only make "noise" in winter anyway, when you are inside the house with closed windows. And you can't hear the brine-water heat pump at all.

Yes, I was also very surprised by the article and am currently thinking about whether the medium is reputable or what reasons there could be for this claim. Maybe the article referred exclusively to air(!) heat pumps.

My mouth is watering. A few weeks ago I explained to the municipal supplier that I will commission a heat pump next year and how the tariff currently looks. The answer was: "We have suspended the heat pump tariff indefinitely for new customers, which means you as a new customer now have to pay the regular 0.42€/kWh and from mid-2022 already 0.45€/kWh. In 2023 it could also be 0.50€/kWh, we cannot say for sure today." But what wouldn’t you do to avoid the nasty gas and oil. :cool: The only advantage of the horrendous price: in return, I will not be taken off the grid during peak loads, as is generally usual with heat pump tariffs. But what if everyone does (has to do) this now and hardly anyone can be taken off the grid when necessary and more and more e-vehicles are charged simultaneously? Then probably a government intervention will take place and there will be forced disconnection at times :) Just kidding aside, this development is really not funny anymore. The noise issue will still be interesting. We ride a lot by bike in the city and now know some properties where the heat pump can already be heard from 50-100m away. Sometimes it is reminiscent of the split units behind the Penny market :-D

Well, there are also purely indoor units. Besides, I don't even know what's wrong with you. I like it when I hear my heating working. Then I know everything is fine and it’s getting warm. Estrich heizen über Tauchsieder was not only terrible for the electricity bill, but also acoustically ;)
