ᐅ We are planning to build a house and are looking for advice and shared experiences.

Hello everyone,
Since we have an idea about certain things and have already done some research on Google, knowing that everything is a matter of personal taste, we still have a few questions.
Our house should have approximately 170 sqm (1830 sq ft) of living space.
Upper floor with knee wall
No basement
It will be a solid construction house.
We are already debating the choice of blocks. But I think Ytong stands out, based on online research and many masons we have consulted.
Our planner says that building with Ytong meets the current standard for thermal insulation.
Do you also think that is sufficient? Or would additional insulation still be advisable despite using Ytong?
The exterior will be plastered as well.
Now regarding heating.
We want underfloor heating downstairs and in the bathroom upstairs. No heating in the bedrooms, where we might consider cork or something similar, plus radiators naturally.
We decided to go with gas and want to add solar panels for domestic hot water.
We have already ruled out an air-source heat pump due to cost reasons.
We might also want a water-backed fireplace.
Our questions:
Is underfloor heating alone enough to heat the house during winter? If not, wouldn’t it be better to skip it and only install radiators? Running both means basically double costs in the end.
In our rented apartment (25 years old), the underfloor heating is not sufficient without radiators. That’s why we wonder if it might be because of the building’s age.
Which gas heating system would you install?
Would you install a mechanical ventilation system with heat recovery?
These are our current questions.
I hope someone can help us before we get started :-)
Thank you

So, we are back to the same point: every type of brick has its own advantages and disadvantages; there is no single perfect solution 😉
Best regards, Bauexperte

This means it is not recommended without an external thermal insulation composite system (ETICS) or similar; at least not for exterior walls. Whether calcium silicate brick can be used for interior walls depends on which material is chosen for the outer shell.
Certainly, calcium silicate brick performs better for sound insulation
So, we are back to the same point: every type of brick has its own advantages and disadvantages; there is no single perfect solution 😉

ok. we live in a newly developed residential area. very quiet. no dogs.
so we should be well off with ytong, which is well insulatedSorry, you don’t seriously mean that, do you? 😕
What will you do if both neighbors get dogs in two years?
I’d rather spend a bit more now on a better building block than be annoyed for years later...

I would rather spend a bit more money now on a better brick than regret it for years...Well, some people said that if you don’t live right on a main road or next to the railway, aerated concrete (e.g. Ytong) should be sufficient?We’re currently deciding between Poroton or Ytong. My builder recommends Ytong.
Y-Tong has a very good insulation value, below 0.1 W/m²K, and is easy to install and work with.
Poroton has similarly good insulation values – I’ve just forgotten the other advantages and disadvantages 😀
Sand-lime brick has a rather modest insulation value but offers good thermal mass and structural properties. It is only suitable for double-layer masonry or when used with external thermal insulation composite systems (ETICS) / external wall insulation.
