Construction costs to achieve KFW 55 funding

Hello,

There is a lot of nonsense written about this on the internet; I don’t feel like addressing it again; I have done so often enough here. If you are convinced that a geothermal heat pump with ground collectors is right for you, then stick to it.

If you have already written so much about it, can you send me a link to the topic?

That also works without storage; for example, the Doc regularly reports his consumption here. One of my customers told me just last week that he only has to spend about €10.00/month on operating costs for his single-family house. I just don’t understand the deeper meaning of a geothermal heat pump in combination with photovoltaics.

The €10 per month refers to what? Photovoltaics & heat pump? And when do you think a photovoltaic system makes sense, for example with an air-water heat pump? And why does it make no sense particularly with a geothermal heat pump? What would you consider the most sensible way to bring a single-family house as described above up to a KfW 55 standard (according to the 2016 Energy Saving Ordinance)?

Thank you and best regards

No offense, but the parts are not yet on the market - neither the price nor the actual function are currently known, right?

Of course the Powerballs are on the market; for example, the red competitor has set them as the standard for their batteries. Rhineland greetings

Strange, then why does the manufacturer themselves announce the PowerWall for mid-February (which apparently has not happened yet)?

I don't know of any shop where you can buy it so far...?

EDIT: As I said, if you google, there is a message that the first 100 PowerWalls were spotted in Germany yesterday.

So, nothing is known yet – I also know the Viebrockhaus advertisement, I never understood back then how they can advertise something they don't even know.

If you have already written so much about it, can you send me a link to the topic?

If you’re interested, please use the search; it’s as much effort for me as it is for you

The 10€ per month refers to what? Photovoltaics & heat pump?

Yes. Photovoltaics _without_ storage, air-water heat pump as heat generator for 159.75 sqm/living space or 693.36 cubic meter single-family house

What would in your opinion be the most sensible way to bring a single-family house as described above to a KfW 55 standard (according to Energy Saving Ordinance 2016)?

That’s a Jehovah topic

I *personally* would not build according to KfW 55 at all; instead fulfill the Energy Saving Ordinance, put photovoltaics on the roof and storage battery.

I find the topic interesting with the storage. We had seriously considered building with Viebrockhaus, but then we mainly decided against it because of the heating. At that time, the financial advisor said that he could definitely recommend the battery – also economically – which made me scoff at him – he was then done for me. We had calculated it back then and it was not even remotely worthwhile. If it is different by now, it would be worth considering. We have 2 empty conduits.

If that has changed by now, it would be worth considering. We have 2 empty conduits.

There are also more providers than _just_ Tesla®
