Air-water heat pump very loud

1 meter FROM the neighbor's house to us

Sorry, I don't understand? Typo?

The calculation is already correct. It apparently calculates days for the rest periods (6 dB surcharge) and at night there is no 6 dB surcharge.

Your rather loud system would therefore need to maintain 11.30 meters at night.

The Rotex would only require 5.02m distance in a purely residential area.

Please apparently delete, it is certainly so. It says up above: Calculation for rest time during the day and at night.

Curve starts at 1 meter. That is also correct. Between directly at it and 1 meter there is a good double-digit number of dB difference. It is exponential and all that.

First of all, almost never pure, but almost always general residential areas are designated. Therefore 40 dB at night and 55 during the day.

Secondly, for example, I already achieve compliance with the TA Noise at 2 meters with a Rotex hpsu compact with 8 kW? And that's nothing special, right?

Thirdly: app is not accurate? And where were the 48 dB measured? Distance?

well, with us it is 65 dB at night and during the day.... now the plumber wants to measure again

how is it basically, our house was there first and 1.5 years later the neighbor's house.

is the house per se unlucky now?

whereas the noise is unnecessary, below -5°C it will run purely as an electric heater anyway. The fan noise is then just a bit of show for your conscience.

Hm, I have a system from Alpha Innotec just like you. In my case, the fuses for the heating element are removed. It was still warm during the last cold weeks (nighttime down to -12 degrees, daytime no more than -5).

And my unit wasn’t very loud either.

does the house have bad luck per se now?

Which house is unlucky?

You of course have to ensure that the neighbor is not disturbed by your emissions.

Presumably, in the end it is about the values from the TA Lärm, which are then measured 1 meter in front of the neighbor's window.
