Plan a gallery in the living room energetically and sensibly

No, you can't... 1x1x1 has a surface area of 6 sqm. 1x1x3 has a surface area of 14 sqm with the same living area. Here, the heat loss will be twice as high. 10x10x1 has a 100 times larger living area but with 240 sqm surface area only 40 times greater heat loss.

With double-glazed roof windows, you run the risk of condensation when it is cold.

Please get a planner who knows what he is doing and has expertise. The house is too expensive for casual philosophizing.

1x1x1 has an envelope surface area of 6 sqm. 1x1x3 has an envelope surface area of 14 sqm with the same living area. Here, the heat loss will be twice as high.

Addition: The heat loss through the envelope, which should not be confused with the energy demand that must be supplied by heating.

Then you would have to calculate with volume of enclosed space.

But of course you are right, someone who knows about it has to come.

I just think that you should always think about something like that yourself before you hand it over.

That has proven itself many times!

Hello,

How much higher could the monthly heating costs be caused by such a gallery,
or how much higher is the energy demand 10 / 20 / 50 %?

If I had to guess, I would tend towards about 8-10%, which you probably don’t care about anyway, since you are planning a photovoltaic system.

But it is also important to us to build energetically sensibly.
Unfortunately, the one cannot really be reconciled with the other.

That is the same in almost all situations in life

When setting up an open space, several points must be considered.

[*]the open space "wastes" space
[*]building an open space means constructive additional effort
[*]the open space must be ventilated, therefore preferably with an electrically operable window
[*]clarify the question of _who_ will clean the window in the future
[*]noise generation
[*]odor development, keyword open kitchen

Heating-wise, we are currently planning an air heat pump,
powered by the energy of a photovoltaic system with energy storage.
In winter, as support, a wood stove with water storage.

What is the purpose of a water storage if the air-water heat pump takes over this function, or do you mean an air-air heat pump?

Rhenish regards

That is a good question. I am also not 100% sure about it yet. It depends on the additional costs of an air-to-water heat pump. With this, you can use the self-generated energy more efficiently (keyword - annual performance factor).

Oh, sorry! I misunderstood the question. We want a wood-burning stove anyway. In this respect, I thought it makes sense to integrate it into the heating system. I still need to analyze the additional costs / benefits more precisely. It was a first idea...
