Well, just had contact with him today. Originally, the heat pump was supposed to be delivered and installed this week; supposedly the wholesaler had it in stock. Now suddenly not. It's supposed to arrive at the heating technician next week, but the master is on vacation then. And he apparently wants to at least inspect the pump himself. So installation won't be until the week after next. I'm a bit pissed off because of that. But supposedly this is already an exception and was achieved with special efforts and costs. The next delivery date from the manufacturer is apparently Feb 22. Unfortunately, we have to wait for this now, because nothing else can be done before the functional heating. This waiting with idle time without being able to do anything else is really annoying. In the meantime, I have already created the foundation for the outdoor unit: Fresh [ATTACH alt="SAVE_20211007_221254.jpg" type="full"]65891[/ATTACH] Cured [ATTACH alt="SAVE_20211007_221308.jpg" type="full"]65892[/ATTACH] And today I finished the construction staircase.
