Recommendation digital heating thermostat

The energy consultant is often just a stamp collector. I would not rely on statements from the GÜ. Only on hard numbers. That means a complete heating load calculation and the system planning.

Ok. Does this already have to exist during the preliminary planning or is it created during the preparation of the documents for the building authority, or when and by whom is it created?

You are making an expenditure of several hundred thousand euros here and have to make decisions that cannot be changed later or only with high costs. I had decided for myself that I would familiarize myself with the trades heating/insulation and electrical work at least enough to avoid the biggest mistakes.

I actually did not intend to do that just now. Or rather, I wanted to do it more alongside the construction.

How do you want to make changes during construction?

The plans are finished, the calculations are done, and the schedule is set.

Just as an example, for the heating load calculation, you already need to know which insulation standard you have, what the windows are like, and what temperature is desired in the individual rooms.

How do you want to change anything during construction?

The plans are finished, the calculations have been done, and the schedule is set.

Just as an example, for the heat load calculation you already need to know which insulation standard you have, what kind of windows, and what temperature is desired in the individual rooms.

Well, for example, defining the electrical system during construction. That doesn't have to be finally fixed during the planning phase.

Who and when then does the heat load calculation?

That is done by the heating engineer or alternatively by an engineering office commissioned by you, which can also calculate the underfloor heating.

But be careful, not every heating engineer participates in that.

Electricity, depending on what you want, it is important to know beforehand where what goes.
Ceiling spots or the openings for them are nowadays normally placed in the concrete slab during the precasting process.
The fuse boxes are now also so large that they should be considered during the planning so that the technical room/laundry room fits.

I am building a bungalow, so there is no concrete ceiling. Therefore, it can be adjusted flexibly. And at what point does the heating engineer do the heating load calculation? That has to be contractually agreed that he does it, I think?
