No, sure. That’s already difficult with night storage heaters, since that’s currently 14-15,000 kWh of electricity.
Of course, not everyone is as clever as you and many others here who change their electricity provider every year. Most electricity customers are stuck with the basic supply tariff. For me now, anyone can check this currently with a price of 52 cents per kWh. That is about 500 kWh per month or 300 euros in electricity costs.
A good average for a single-family house. Before my photovoltaic system, I had an annual consumption between 5,000 and 6,000 kWh of electricity without heating. But as I said, there are almost only savers active here in the forum. Meanwhile, thanks to the photovoltaic storage, I’m down to 1,300 – 1,500 kWh.
The all-time popular financial advisor Dr. Klein also calculates something like that in.
Based on this rule of thumb, the additional costs for a house with an area of 150 m² amount to 600 € per month, for example. Add 1 € per m² as reserves, and you come to a total of 750 € per month.
Now if you add a few extra costs or regional price peaks or a bit more reserve formation, you’re quickly at 1000 euros. I didn’t make these numbers up.
