Yes, that simply doesn’t work... and many of the "Neuhausbauer" are then angry at the GÜ afterwards because he supposedly did not build the house free of defects... many do not see that it often lies in the user behavior...

Does the electricity consumption of the air source heat pump come from the usage behavior? Because one ventilates too much/wrongly/too little? Always assuming that the temperature for the house is not set to 25 degrees ;)

Recently I learned that it also depends on the installation distances of the underfloor heating or that the weakest room has enough heating surface :D

super.
we stand as blonde laypeople in a house-building nightmare.
And if we know one thing by now,
it's that our trust in the construction department involved is far below zero.
What we have had to learn over the internet in the last few months,
just to know that the "experts" worked incorrectly or not at all....
for example, someone (architect?) completely forgot to plan the grounding.
The plumber installed 80% of the water pipes without insulation.

The underfloor heating has not yet been installed. What should I know? I only trust the workers as far as I can spit.

I will have all work checked from this week by an independent expert.
But if I can already prevent the next mistakes in the preliminary stage...

In the basement (except storage room) and ground floor we have ceiling heating.
First floor and attic will get underfloor heating.

Originally wanted an air heat pump from Ochsner because they are supposedly super efficient.
But the heating type that is always planned or included in the offer by the prefab company
is only Rotex or Mitsubishi.
The latter is more efficient, so we chose that.

But, with how this whole build is going, it would be a surprise if at least that runs well.

No one is competent. From the architect to the "construction manager" or responsible regional representative of the prefab company

Take a look at the BAFA website - there you can find current pumps with the COPs. For further information, I can also recommend the pink forum to you. When designing the heating system and the piping system, make sure that your heating specialist carries out a room-by-room heat load calculation - don't be fobbed off with "everywhere 15 cm pipe spacing." Validate the planned heating system - check the U-value and do a heat load calculation for your entire building using the heating energy demand calculator (you can find values for this in the [Energieeinsparverordnung] documents).

Good evening,


That is good!


They just move the source of the noise - in my experience.


With Rotex, I know you don’t have a bad provider, as long as the system is adapted to the house calculation. I have no experience with Mitsubishi.


Generalized statements are not constructive and help no one; not even you.

There must be a reason why you chose "your" provider; maybe the explanation lies in the choice itself?

Rhineland regards
