Construction costs are currently skyrocketing

How did you set it up? We also only have DHW via gas at the moment, but I can't reach those values. I set DHW from 1 pm to 9 pm. Consumption was now 44m³ per month.

DHW time from 5:30 am to 7:00 am (because I always shower early and my wife sometimes showers early) and from 5:00 pm to 8:00 pm (when the kids take a bath). Boiler temperature 60 degrees and reheating at 45. We also have 2 solar thermal panels on the roof.

I don't think so, your house isn't that much bigger. WW you can also check what the consumption will be and possibly change something. There is a separate topic about this here in the forum.

One is talking about final energy with HP electricity,
the other about primary energy district heating.

You have to talk about the same quantity.
That would be in this case heat quantity in kWh.
6 MWh at 9 ct/kWh - 540€ p.a. sounds about right?

Well, our consumption was now in exactly 1 year at pretty much exactly 2000 kwh for heating and hot water

Our heating engineer talked about 6000kwh for 158sqm and Kfw55

I think means electricity consumption, right?

The heating engineer certainly means heating demand.
Whereas with the Building Energy Act 2017 (KfW 70) and 162m² I’m scratching the 6000 kwh heating demand from below (calculation - practice is still pending), so 6000 for KfW 55 still seems a bit high to me.

was faster.

s Heizi definitely means heating demand.
Although with the 2017 Building Energy Act (KfW 70) and 162 m² I am barely scratching the 6000 kWh heating demand from below (practical calculation is still pending), so 6000 for KfW 55 still seems a bit high to me.

Surely I mean electricity consumption.
You were calculated a heating energy demand of 6000 kWh for KfW 70 and 162 sqm? Including domestic hot water?

Surely I mean electricity consumption. You were calculated a heating energy demand of 6000 kwh for kfw70 and 162 sqm?

But the heating engineer from means heat quantity. Ah no, now I have confused heating load with heat quantity over the year. Wasn't there an estimation formula for that?

These debates here always seem schizophrenic to me. At least personally. They encourage me because this Germany can never, ever, ever start a war again... the soldiers would already run home on the way to the front, because so far out there there is no internet, no 23°C, no shower, etc... You have to consider: Over 50% of four-person families in Germany live on less than 3,900 EUR net... Single parents with 2 children on less than 3,000 EUR net per month...

Phew, someone is really spouting some flat clichés here that I don’t want to leave uncommented. Two of my former teammates are professional soldiers and were severely wounded years ago in Afghanistan during the Good Friday battles. One of them even went back to Afghanistan for another three months despite having a glass eye and paralysis in his left arm. My brother was also deployed abroad several times as a professional soldier. Neither he nor his comrades show any signs that your statement is true. Regarding the topic of heating costs, I had another conversation yesterday with my father (79 years old) about heating costs. He lives alone in a corner terraced house built in 1974, in which several rooms still have the original windows and no insulation improvements have been made. Yesterday he was complaining again that heating oil is so expensive and that this year he had to fill up with about 2,200 liters for 3,000 euros. But the blame lies solely with the stupid neighbor because she ordered the oil for the whole row at the wrong time. He is therefore sure that next year it will be much cheaper again and only cost half... What I really want to say: Right in front of his house lies the local district heating network and he could be connected at any time. He has been asked several times but always declined because: That newfangled stuff, that would make me dependent on the provider. What if they raise the prices after the fixed price period expires? Well. 1 liter of heating oil has a calorific value of about 8 kWh. So this year he bought the kWh for around 17 cents. The district heating provider offers 8 cents with a price guarantee until 2030. Our neighbor diagonally opposite is just like my father, sold his house a few years ago and has since been living in a 3-room condominium and currently pays about 450 euros a year for gas. What I’m getting at: Everyone has chosen their living space themselves. Some opted for lower cold rent because until recently the energy costs were practically irrelevant. From my point of view, it was only a matter of time before energy costs rose...
