Hello everyone,
I have an unusual question:
Is there anyone within about 100 km (60 miles) of 46325 who has an LWZ 504 system that I could take a look at?
We (my wife, our young son, and I) are planning to install this system in our new build.
However, I’m worried that it might cause noise issues, or that there might not be enough space in the utility room, and so on.
It would be great to talk to someone who has installed a system like this.
Best regards

I assume every heat pump makes some kind of humming noise, whether it is an integrated system or a split design. We only hear it when the house is completely quiet, and the heat pump is heating water.
We don't hear anything during ventilation or heating.
The unit is installed in the basement utility room and is no larger than a wardrobe.
A proper sound insulation on the floor and for the ventilation is important.

Unfortunately, I am too far away to help in person. However, I can reassure you that the system itself is very quiet. We had a better soundproof door installed in our utility room, so we no longer hear anything from the heating unit. By the way, the photovoltaic inverter is louder than the heating system.
If you have any questions, feel free to contact me; and please don’t forget to apply for the subsidy with the LWZ 504. You can get a grant of 2000€ for it.

Especially in winter, the system is not exactly quiet. You don’t hear it when the heating is running, but you do when it’s producing hot water, even through an 11cm (5 inch) calcium silicate brick wall and a standard door. The surrounding walls should ideally be thicker, or the system should be installed in the basement. It sounds worse than it actually is, though—it’s not really disturbing.
Regarding subsidies, it is very important that the application reaches the relevant authority at BAFA before signing the contract with the general contractor or heating installer.
The space requirement definitely needs to be considered. We had originally planned the utility room differently, but SE then changed the maintenance guidelines, so the system had to be moved to a less favorable wall. The system is not small, and the piping to the exterior wall is quite large (about 40cm (16 inches) diameter per duct).

The heating engineer recommends a split system to me.
As a layperson, the advantages seem to outweigh the disadvantages, and I think I will probably decide on this system.
I downloaded the technical documentation for the system. We also had to move the location, but to a more suitable wall. It is now basically in the corner of the house.
Did you have the grilles or connections for supply and exhaust air built in directly, or did you use core drilling for that?
