Is that how it’s usually done? How are the pipes then covered (is closing the screed included in the above offer)? Why don’t they remove the old screed completely and then redo it? Is that much more expensive than milling?

Removing the screed could well be done as a DIY job ... BTDT.

If the insulation makes a significant contribution to the targeted KfW70 standard (what exactly is that today in 2016?), in my opinion, an air-to-water heat pump can also be considered. Surprisingly, the investment costs are just as high as for gas condensing boilers.

Insulation must (and want to) be done anyway, so we are using 16cm ETICS on the exterior walls. Basement ceiling is obviously insulated as well.



Actually, milling should be the ideal option. Milling takes a total of 2 working days, afterwards we can install the heating circuits ourselves and then plaster over them.

Completely removing the screed is certainly possible as well, but it would probably be significantly more labor-intensive. Here we would likely eventually reach the limits of our own capacity for self-performed work, since we want to do a lot of the electrical work ourselves soon.

I am sometimes a bit baffled by how numbers are juggled here. And how these are sealed off.

Up there it specifically states the package for the heat pump is priced at 14,500€. It only takes a search to find out the "online price" for it, which is about 7,500€. And then you just tick the box?

No wonder it doesn’t surprise me that houses can’t be built for under 300k.

*micdrop*

Edit: 8,000€ for milling and that takes 2 days. Who all comes to mill in order to complete such work? Or is the material made of gold?

Completely right, and important, to question such prices! Or not?

I see that differently due to my profession - I just experienced it live during our renovation. Completely removing the screed is faster/cheaper than milling for the heating coils ;) Rhineland greetings

You draw conclusions about Wäbdiseiner versus IT guy; not good ;)

Correct, I totally agree with you! But I see it very matter-of-factly: You can get three quotes and then compare them, and the best offer is then awarded the contract (how to identify the best one is not going to be discussed here). Any internet prices or statements in forums (too cheap, too expensive) are completely irrelevant; only the truly realistically available option counts.
