German solid house insolvent?

[*
Trench collectors are not bad per se. They just need to be deep enough and long enough. They are very common in Scandinavia and Austria. And it is colder there than in Germany.
[*]The heat pumps from DM are OEM products from a small company. Actually not bad, only DM lacks any expertise.

[*]The company Ökostar had expertise and should have appeared at every PDS. At least this did not happen with us.
[*]At the PDS, we were sold an extension of the trench collector. When we asked if it would even fit on the property, we were told the collector is laid in loops and will fit.
[*]Who is surprised? One of the latest letters from DM told us "IT does not fit." Unfortunately, the house does not get warm. Just take an electric additional heater.
[*]The soil report was also available. From a depth of 80 cm to 80 m, only gravel and sand. Our supervisor Mrs. G. Stein congratulated us on this soil. Very good for building. What she ignored is that this soil is unsuitable for trench collectors.
[*]Calculated length of the collector: 125 meters with solid bottom!
Installable length on our property: 82 meters. So about 33% of the heating capacity is missing.
[*]Since we have sandy soil and accordingly only about 1/4 of the assumed heat yield, anyone can calculate how we are supposed to warm the house.
[*]And in the end, the heat storage tank was also wrong. Heat pump and solar thermal were purchased for both heating and hot water. Unfortunately, the storage tank only supports heating and not hot water.


[*]If you have no idea, and that is not bad, then you should get help. Especially if there is a specialist company in-house.
[*]Oh yes, until communication stopped — by the way from DM’s side — our problem was not solved.
[*]I was only told that the sold system does not work and I should use electric heating. (In a KfW 40 house)

Thanks for the post, unfortunately all DM houses were handled this way.
A company like Reisser should have intervened, but it did not.
He knew that he was cheating DM-Massivhaus customers with his trench collector.
I had thought that the company Redmann would not associate with such a manufacturer of cheating trenches, well, Mr. Redmann simply does not stand by his word.
My tip for DM builders: buy your trench collector through the company Redmann, he does not have a Ltd with €500 liability.

Mr. Reisser from his Zerreisser forum wants to sue me now, my legs are shaking with fear. D

One could make a nice day out of it at court.

I am waiting, and then we will see who laughs last.

PS: I still have a few login names.

It's not entirely clear to me. I also had to have a made and am building without a basement.

Why without a soil survey??? We would have built with a trench collector and a soil survey was indeed carried out for us!! Was this only for the statics of the basement??

must also be done for a house with a slab-on-ground foundation, to check whether the soil has sufficient load-bearing capacity.

Dear Mr. Trilino

We happened to read your inquiry. Our company has nothing to do with the German Massivhaus. Unfortunately, you have copied our brand name. Also the construction description - at least this we know - has been copied.

Unfortunately, that is the case. If you have any questions, call me: Roland Opitz 030 29352468.

Kind regards.

Which brand name and which construction description – what exactly was copied?
