I would be interested in an assessment of how much higher heating costs (in percentage) you can expect in a house built around 1970 with solid construction according to the standards of that time (including windows), compared to modern insulation as commonly used today.
Are there significant differences? This concerns exterior walls and the roof.
Where are the biggest heat losses likely to occur? Exterior walls, windows, or the roof?
Which renovations would be particularly necessary, and which ones less relevant?
Thank you

Now it’s getting exciting Well, I don’t really understand the technical system itself.
So I can only ask from a logical perspective and possibly make a comparison to a motor vehicle (which I understand a bit more).
What’s the use of the most efficient diesel engine if I want to drive at 200 km/h (125 mph) and have to constantly push the car to the limit? Then any savings quickly disappear.
Sometimes a slightly more powerful engine works wonders...
No, no, that’s not what I meant. Just that the topic always tends to spark heated debates : )
Regarding your example (which I also really like): the speed limit is 100 km/h (60 mph). Your car, which can go 200 km/h (125 mph), is oversized.
Similarly – with heating, you don’t want a thrill (28°C / 82°F), but to get from A to B comfortably warm.

€uro can probably explain the inefficiency better, but I’ll try as a layman.
With a car, you can control the gas flow.
At least with our heating system, that isn’t possible.
The burner starts up, heats at full power, and stops again after just 3 minutes.
To continue the car analogy, frequent starting and stopping would wear out the starter motor.
Also, a car consumes more fuel during a cold start.
The same should apply to the heating system.
