Allegro-Haus GmbH experiences

First of all, thank you very much for your feedback.

We plan to operate the underfloor heating with geothermal energy ([Bohrung]). Are there any problems with low outside temperatures? After all, the ground floor and the upper floor have to be supplied with it.
Who has experience with how high the room temperature can be regulated at maximum?

Where is the problem supposed to be? We have geothermal energy with underfloor heating and the screed drying program easily reached 40 degrees without a heating rod!

But whether geothermal energy is even possible is shown to you only by the soil analysis. So first have a soil analysis done, then choose the type of heating.

..We plan to operate the underfloor heating with geothermal energy (drilling). Are there problems at low outdoor temperatures? After all, both the ground floor and the upper floor have to be supplied with it.

Heat pumps require a supply temperature to the heating surfaces of approximately <= 35°C for efficient operation (seasonal performance factor). At the same time, it must be ensured that the produced output can actually be utilized. (Heating surface dimensioning, hydraulics). The heating output must therefore correspond to the actual demand (DIN 12831). Furthermore, the source must sustainably be capable (capacity, extractable energy) of sufficiently supplying the heat pump permanently. If the actual demand (capacity, energy) for heating and domestic hot water preparation is not known, it is likely to be quite difficult to establish an economically viable overall concept. With insufficient or missing exact planning/dimensioning, one may potentially create a money pit. Investment, or the capital service for it, and later consumption costs should be in an economically balanced ratio.

...Who has experience with how high the room temperature can be regulated to at maximum.

The desired room temperatures are contractually agreed upon in form V of DIN 12831. Depending on this specification, the room heat loads, the dimensioning of the heating surfaces, pipe hydraulics, the heat generator, as well as the source design, result from it.

Heat pumps require a supply temperature to the heating surfaces of approximately <= 35°C for efficient operation (annual performance factor). At the same time, it must be ensured that the produced output can actually be taken up.

The underfloor heating is one thing and the water supply for showering, etc. is another. The water temperature generated by the heat pump will not exceed a certain value. I currently have district heating where the supplied water temperature is easily enough to scald. Does a heat pump achieve a similar temperature (without an electric heating element) or must one expect significantly lower felt temperatures?

Which type of heating is the most economical, if we disregard gas?

The standard is supposed to be an air/water heating system, or should one rather prefer a ground/water heating system with deep drilling?

Are there any experiences regarding the noise levels of both heating systems?

If a construction contract is concluded, how does the financing proceed?

I imagine it as follows:

[*]The contract is signed, construction begins.
[*]After completion, e.g., of the floor slab, first payment to the house sales company
[*]Construction continues, second payment after completion of the next construction phase, etc.
[*]In other words, no down payment before the construction phases, right?

Thanks for the feedback

[*]Construction continues, second payment after completion of the next construction phase, and so on.

Thanks for the feedback

Regarding the economy, Euro will write to you

But just look for a company that creates all the plans without getting paid. You will have to make a small % down payment in order to get the planning submitted to the building authority.
