Exorbitant power consumption house construction single-family house experiences

The consumption cannot even be remotely explained by electric screed heating. We also had to do it that way and ended up somewhere around €1500.

I've heard a story where the shell builders had heaters running in the construction trailer over the winter. But 25,000 kWh... where else could that come from, it can't be explained with the normal construction machines.

We had to do it that way too and ended up somewhere around €1500.

Same here. Screed heating in autumn with electric heat generator, as the district heating station was defective. Final invoice was just under €1600 plus connection, disconnection, etc.

Unfortunately, there is no reading error, I saw the over 25,000 kWh myself on the meter

What kind of meter exactly? Did you also see the initial reading at 0 kWh? And even if the construction trailer is heated along with it, impossible. We agree that this cannot be the case.

That adds up quickly. Most devices have a three-phase power connection. Just a cleaning machine, crane, saws, heating lamps, lighting, etc. If they heat the house for weeks with electric fans, you can imagine that.

Especially when the construction company doesn’t have to pay for it. Still, overall it’s quite substantial.

Our butcher shop here in the forum has consumed about the same amount in 3 years. However, so much went wrong there and 2 units. Here it is strange.

That adds up. Most devices have a high-voltage connection. Just a cleaning machine, crane, saws, heat radiators, lighting, etc. If they heat the house for weeks with electric fans, you can imagine that.

Moreover, if the construction company doesn’t have to pay for it. Still, in total very enormous.

Sorry, but this is not at all explainable with construction machines. Not even close. Cleaning machine runs for a week and not continuously, crane only consumes when someone uses it, with a bit of standby power. That might add up to 300-500€ in a single-family house over the construction period, but not 8000€. Completely wrong order of magnitude. Whether electric fan heaters or heating units over underfloor heating is irrelevant, both consume electric power 1:1. And several comparative figures have already been mentioned.

25,000 kWh over an assumed 9 months construction time corresponds to 90 kWh per day or 3.8 kW continuous load on average. 24 hours a day, 9 months long.
