Thank you very much for your feedback!
It already sounds a lot like "we've always done it this way."
That sums it up quite well.
I would definitely at least air-condition the bedrooms or have refrigerant lines etc. installed during construction. You wouldn’t even need a refrigeration license for that.
Noted. Thanks.
You have to be very careful here. This is a geothermal heat exchanger for the controlled residential ventilation and if it’s not executed meticulously you’ll have more problems than benefits afterward.
Ah ok. Then I already have the exact term with which I can google. As far as I understand, he has already installed it. Then maybe it’s better to leave it as is, right?
Yes, it cools your floor. But it hardly affects the air temperature and humidity in the house. This has been debated often here and everywhere. Yes, it’s a cooling almost for free but it doesn’t cool what should be cooled to have a noticeable effect.
Ok. Understood. Ergo, snake oil.
An air conditioning system costs roughly the same in investment and then produces about 200 euros operating costs per year. But then you have the desired temperatures exactly where you want them.
I will address this again. It will probably come down to having the lines installed first and then possibly retrofitting the air conditioning later via a refrigeration technician. Then the option with the geothermal heat exchanger for the controlled residential ventilation would also be obsolete.
The result was that I had the heating load calculation created and also the installation planning of the underfloor heating done.
Where did you have that done? Via the internet?
We are also getting Wolf now.
Which model?
If you have heat recovery in the controlled residential ventilation, the geothermal heat exchanger is counterproductive anyway.
According to HB, you should be able to switch between controlled residential ventilation with geothermal heat exchanger (summer) and controlled residential ventilation without geothermal heat exchanger (winter).
What else will be installed besides the heat pump?
What do you mean? Probably also a hot water storage tank, since both the flexoTHERM and the Arotherm only have 190l tanks. In my opinion, that is too little for a 4-person household. And otherwise, just a controlled residential ventilation.
Well, and a photovoltaic system. But that’s a different topic for now.
You should commission the room-by-room heating load calculation and the design calculation of the underfloor heating with the desired parameters externally.
Do you have a recommendation?
