Are different projects being mixed up here in the flea market?

Did you scrap your PC without saving the password for the forum account in a second place?

Wow - the old computer stopped working and then nothing worked anymore...

The BAFA on-site consultation shows that we will achieve an Efficiency House 55. The balcony and garage are the thermal bridges that are somewhat more complex. Unfortunately, the energy consultant did not determine the actual costs. He created a report based on the inadmissible old minimum requirements of BAFA from 2014. However, according to BAFA 2017/2020, the total costs of the measure must be determined. BAFA has completely slept and has apparently accepted false and invalid on-site consultation reports from the Dipl.Ing office for years. When addressed, the BAFA employee reacts very irritated, just like the Dipl.Ing office. The estimated costs are at 150,000 euros – which is obviously ridiculous. We are thus underfunding – our numbers are now clearly moving towards 280,000 euros. At least the new funding from 01.07.2021 is now available. It is really worth planning everything well with 45% funding...

In the course of the CO2 price increase on oil and gas, should pellet heating possibly still be considered?
...

I am faced with a similar consideration, installing a pellet heating system - starting from oil. However, I have now heard several times that such a heating system is generally significantly more maintenance-intensive than, for example, a gas heating system. This then raises the question for me whether the lower heating costs of pellets are not eaten up again by the maintenance.
