Problem with LRA: Location of heat pump

I'm with Alex on this.. The topic of noise is far too complex and fraught with potential interference sources to initiate a planning and approval process here. Anyone with some knowledge about it would shake their head... This would be a several thousand euro expense and in the end probably completely exaggerated structural measures, because the planner prefers to play it safe... This guideline makes sense. Noise is a special topic that is also perceived subjectively differently.. If there is to be a regulation, then please also introduce a mandatory measurement of the neighbor's snoring noises with the window open... Or the barking of the neighbor's dog

Hi,
here:

Gas with solar thermal uneconomical!

I wouldn’t be so sure about that. Until the last tightening of the eco-fascist regulation, the gas boiler was hardly to beat economically if you really add up all the costs over the lifetime of the system. Now, thanks to the eco-crazies, you’ll easily have to nail 15 sqm of ST on your roof instead of just 5 sqm. That should be about 5-8 k€ additional costs. With that, the air-water heat pump is just about on par in TCO with the gas boiler with ST.
If you’re installing a controlled residential ventilation system anyway, you might still have a chance to get by with just the small ST, then the gas condensing boiler is almost certainly cheaper.
By far the most affordable heating system is still the gas condensing boiler without ST.

Regards,
Andreas

Hello everyone.
Legally, it looks like this:
If the development plan has a stipulation (not a note) regarding noise emissions or immissions (e.g., only sound power level of xx dB or xxdB must be maintained at the boundary), one should follow the instructions of the LRA.
The LAI guideline has NO legal binding effect, unless there are stipulations in the development plan.
Regarding regulations in building permits. DOES NOT MATTER.
Approve and build as you like. If there is later noise trouble with neighbors and the LRA, only the limits of TA Lärm are decisive. Compliance with the TA Lärm limits (general residential area 40/55 dB) at the neighbor’s living room window (to be opened), kitchen (with dining table), or bedroom can be calculated roughly by a noise propagation estimate: using a noise calculator based on the sound power level of the installation to calculate the immission at e.g. 4 meters, the immission decreases by 6 dB with every doubling of distance or simply enter the correct distance.
If the TA Lärm limits are met, the LRA has NO authority to take action against the installation.
The neighbor will then be uncomfortable.

Of course, that is NOT good....
Such an approach is therefore...

cheers

Forgot something. Maintain distance areas, so under no circumstances build the thing within 3m of the boundary, unless it is in a privileged building (garage, storage room) within the building boundaries and not on the garage roof. Distance areas may lie on public ground (street, public park...). In Bavaria, no heating systems are allowed in privileged buildings, this may also apply to heat pumps.

I agree with Alex.. The topic of sound is far too complex and fraught with possible disturbances to initiate a planning and approval process here. Anyone who knows a bit about it shakes their head...[QUOTE]

No. The topic is everyday and there have been corresponding planning and approval procedures for a long time. Just not in residential construction. From my point of view, the manufacturer should be held liable for an incorrect indication of the sound power level. I assume that is legally not a problem. Then it is up to the executing company to ensure correct installation. If a sound forecast has to be calculated for that – so what? The need to protect the neighbors counts in my opinion more than the additional effort in planning and execution.

A guideline can also be considered a recognized rule of technology, so your statement is not correct.

Somehow it drifts off. The starting point is that a single new building is placed in a gap in an old residential area. And according to the attached drawing, quite massively into the south garden of the northern neighbor, who is now, of course, fully in the shade. Since the whole thing takes place in Germany, not in Morocco, the shade is probably not really welcome. Additionally, the humming box is now supposed to go there as well. In the shade with humming, I would be totally thrilled. In this case, the location of the pump is really unacceptable. And the authority is thus completely right. What to do now? Since there is certainly natural gas on the street in the old residential area, plan a condensing boiler and some solar thermal. Or instead of the heat pump, put the contraption to the south.
