@€: What is your graphic supposed to tell us? That with 15MWh/a, well, you picked a very large or poorly insulated house as an "extreme" example to show huge differences?

Also, I don't understand why a condensing gas boiler should have such a difference with poor planning. Especially condensing gas boilers are much more tolerant of planning errors. Or how do you explain that?

Hello €uro,

I also have to work from time to time...


It has recently become known that Alice Schwarzer did not understand the parable about the glass house.

My post clearly states:


Since when is external expertise dependent? Once again, for you, clearly formulated this time: the vast majority of our clients bring the expert(s) they trust; mostly unknown to us and always welcome.


I cannot do that because I have no insight into the expert's reports => the contractual relationship exists between our clients and their expert, because I have no knowledge of any lasting disputes between external experts and our BL either about our clients or within internal relationships, I do not promise any consumption figures and therefore do not have to engage in these discussions.

The PHPPs that interest you and are in my possession usually have a size of 4 MB – starting with the brief manual and ending with the EB certificate; I cannot upload the Excel file.


One sentence suffices, which extends the house rights to the externally engaged expert. For any further possible displeasure, either the client or the TGA planner would give us a hard time; to my great pleasure, I cannot serve that.

Rhenish greetings

Because with current gas condensing boilers, installation costs / consumption do not get out of hand as much with incorrect sizing as with heat pumps.

@€
please adjust the price increase in your graphic to real values
heating oil is at 10% increase, natural gas at 7-10%, and the rest at about 6%.
