Construction costs are currently skyrocketing

We just got a price increase starting in March, to 34ct...The base fee also increased but is still cheaper than many others. If I find time, I'll see if there is something good and cheaper. When we moved in last autumn, (we couldn’t have taken the previous contract with us) EON via Mediamarkt with 32 or 33ct would have been the cheapest. I have now done some calculations... We are still cheaper now as long as we don’t suddenly consume a lot, because the base fee with our provider is significantly lower.

People :D. 2017: Called over 30 tilers until I found one. 2023: Found one who is interested and will come by next week for a quote with the 4th tiler. At the end of 2022, I was still looking for all trades. Without success. The further 2023 progresses, the more projects seem to fall through for the craftsmen and suddenly you get craftsmen. I can't explain it any other way.

Short technical question that surely someone can answer.... The outdoor temperature sensor of the heating system... How does it get from inside to outside? Simply drilling a hole into the aerated concrete and then sealing it with foam insulation results in a hole in the thermal envelope, doesn’t it, or am I mistaken?

Just like every outdoor light, doorbell button,... drill a small hole, plaster later.

But always with a slight slope outward ;)

Does that actually make sense?

There are now balcony power plants

With 920 watts and 800-watt inverters for about €750.
Without mounting material

How does it count if you go over 600-watt inverters?
