Construction of a 144 sqm bungalow in Fichtenwalde (near Potsdam)

But without connection of the meter cabinet?

Everything went smoothly. (Of course, we don't have such a low VA as you, but that was already the case in 2009)

With the laying distance and desired temperature in connection with KfW55 (20°), the flow temperature will hardly exceed 26°. (we are talking here about OLD -14°, so a harsh winter)

With the installation spacing and desired temperature in connection with kfw55 (20°), the flow temperature will hardly exceed 26°. (we are talking about OLD -14°, so a harsh winter)

Does this now mean that the installation determines the flow temperature? If the installation was emphasized as important, nothing can be changed in the setting? I still don't understand the connection between flow temperature and the installation of the underfloor heating / heat pump setting.

Since there was no answer to the previous question :-) I'll try with another one. It's about the router. I wanted to get one, after consulting with an electrician. We will first get a connection (copper) through Telekom. Fiber optic might be possible later. Now the question is what would be better, or what the difference is.

I have the following devices in mind:

- AVM FRITZ!Box 4060 (Wi-Fi 6 Mesh Router, up to 4,800 MBit/s (5 GHz) & 1,200 MBit/s (2.4 GHz), 2.5 Gigabit WAN port, especially suitable for fiber optic modems, DECT base, German-language version)

or

- AVM FRITZ!Box 6690 Cable (DOCSIS 3.1 cable modem, 4x4 Wi-Fi 6 (WLAN AX) with 4,800 MBit/s (5 GHz) + 1,200 MBit/s (2.4 GHz), 1x 2.5-Gigabit LAN port, USB 3.0, DECT), white

The first one states that it is not a modem. Can I even use it? I don't want to buy something wrong.

I would take the first one if I have fiber optic. The second is for COAX cable (so Kabel-BW, Vodafone, Unity Media).

Otherwise, depending on what you need. As a single device without additional access points, I would take: FritzBox 7590, for VDSL :D

I use the AVM 5530 for my fiber optic connection from the [Stadtwerke]. It was provided by them and is not very good when it comes to Wi-Fi. Now the 5590 is coming out. I would prefer that one. For my DSL connection, I use the 7590. It is perfect.

That is really annoying. The general contractor started on time, everything was more or less on schedule – and now this. It would be too good to be in line with the holiday planning. But if it is not the case and the rent is actually that low, don’t stress yourself extra with this matter. It is what it is. There are worse things. And storing the furniture for a month and moving into a holiday apartment makes little sense for you.
