Hello dear community,
Since I have encountered various figures during the planning and consideration of our single-family house, I would like to start a thread where everyone is welcome to share all kinds of information.
Please move the topic if I have posted it in the wrong section.
I’ll start with the house of a good friend:
Type – 1.5 stories, gable roof, basement, approximately 140m² (without basement)
Heating – gas condensing boiler with about 400L (105 gallons) buffer tank and solar panels for hot water (2 panels)
Fireplace – yes, but without water jacket
Ventilation – Systemair VC400
Wall construction
- Eder Thermopor 016 – thermal conductivity Lambda 0.16 W/mK
- Insulation mineral wool rigid boards 120mm (5 inches) WLG035 and lightweight exterior plaster 20mm (0.8 inches)
- Heat transfer coefficient U-value 0.18 W/m²K
Number of occupants – 2 adults and 1 child (2–3 years)
Consumption values (as of 2015):
Water/sewage – 50m³/year (1,765 cubic feet/year) → about €250
Electricity – 2,700 kWh → about €900
Gas – 700m³ (24,740 cubic feet) → about €525 (although the house is heated a bit “too comfortably” for our taste)
Waste disposal, broadcasting fees, property tax… are very region-dependent.
I am grateful for any improvements and tips and look forward to strong feedback.

Meat without side dishes?
Stew without fried bacon?
No, that’s not my wife’s kitchen.
Good food unfortunately also consumes a lot of energy.
PS: Luckily, in summer we only use gas on the grill 🙂 Originally, the discussion was about the estimated amount of energy from 3 cooking zones at 20 minutes each at 2 kW, and with that I can easily make side dishes alongside the 10 minutes needed for the steak. That’s enough, for example, to boil potatoes (which take a few minutes longer to come to a boil, but the meat only needs 10 minutes), or other things. Easily. So please read carefully :P

I’m just comparing it to my wife’s cooking, and that’s a world of difference.
Not to mention when I cook—though that only happens on holidays and involves full menus.
The other point was a comparison based on a total consumption of 600 kWh, and with 2 kWh per day, you already use more just for cooking.
I don’t think so, but I suspect you might be underestimating the 2 kW; that’s the power of an electric kettle at full capacity. Normally, you don’t need that much power—once water in a pot starts boiling, only a fraction is required to keep it boiling. Overall, you can boil for longer or more extensively with the mentioned 2 kWh than you might expect.

Do you cook yourself? Not meant as a judgment, just curious to better understand the low energy consumption.Don’t worry, I don’t take it as a judgment 😉
We usually have breakfast and lunch at work. In the evenings, we do cook, but I’d say mostly small meals—sometimes pasta, sometimes a steak, or something baked. Nothing like a roast simmering for 4 hours… On Sundays, we cook bigger meals!
If you calculate it roughly, we use about 2 kWh per day. Our LED lighting is negligible. The (52") LED TV, which I measured at 110 watts/hour, isn’t a huge factor either. Most of the energy is probably used for cooking, the coffee machine, and the washing machine...
No, it’s a 75m² (800 sq ft) apartment in a 10-unit building without photovoltaic panels. As I mentioned, a big advantage is that the hot water is produced via district heating, so during the day we’re both at work and all appliances are rated A+(++).
Admittedly, I was surprised myself. After the first year, my wife insisted I look for a cheaper electricity tariff because we were still on the basic tariff 😉 We’re still on it today because every other tariff with a basic fee is more expensive. Currently, we pay about 20 euros per month :-)
