Project Homeownership - Basement, Ground Floor Plan - Tips

Radiators need significantly higher flow temperatures than underfloor heating. With that, you ruin the advantage of an AIR-TO-WATER heat pump.

For heating: Is the room inside the heated envelope: yes. Then install underfloor heating and always run it at a very low level. And yes, the heating-up behavior is significantly slower than with radiators.

Is it a room with very few hours of use? Then an electric heater in addition to the underfloor heating would be an alternative.

Yes, electric heaters or infrared heaters will probably be an issue. Maybe there is also something like a preheater for the controlled residential ventilation, but only for one room. Then you could simply warm that room with the air when needed.
But we are not there yet.

The idea with infrared or flat collectors seems to be the best way. Although the efficiency is said to be very poor.

hmm....

Thanks for your opinion and more of it is welcome.

And yes, the heating-up behavior is noticeably slower than with HK.

That should be manageable if you reduce the pipe length by dividing the room into several zones.

Yes, there are opinions.

Show me.

I drew the house in Sweethome 3D. Without this software, I wouldn’t have noticed quite a few mistakes made by the architect.

Tell me, what kind of mistakes were those?

My wife wants a black tub as an eyecatcher, that’s why it’s so central.

I didn’t want to be greeted every morning by an eyecatcher on which you can see every speck of dust.

I see a few other aspects, but I find your opinion very helpful.

I always try to write in a comprehensible way so that every reader can make their own judgment.

I like the idea of good insulation and the very massive construction with concrete. After all, there is more and more radiation and external influences. Concrete is a very dense building material that effectively shields radiation, noise, etc.

So concrete from a naive idea of the Castor container? – well… That shuttering blocks could establish themselves at all for residential buildings was only possible because they consist of insulating materials that wrap the relatively poor concrete well in terms of insulation. The current generation of shuttering blocks with their exterior side made of wonderfully integrated ETICS just barely meets current standards. In this respect, one can only speak of “sufficient” insulation here.

It seems to me that marketing romance got you completely.

That should be manageable if you reduce the pipe length by dividing the space into several fields.

I don’t understand that right now.

By PM or email? From which area would you like views? Outdoor area or indoor area? With interior or without?

Tell me, what kind were they?

For example, the staircase in one design was quite steep. 17 steps 18/24 doesn’t necessarily mean much to everyone. The garage width was also a bit narrow. Window planning doesn’t only have to be done from the outside. From the inside, some windows suddenly appear disturbing.

I didn’t want to be greeted every morning by an eyecatcher on which you can see every speck of dust.

That’s my wife’s problem, she wants that. I want KNX/EIB, so I’ll have to hear everything if something doesn’t run as it should.

I always try to write in a way that is understandable so every reader can make their own assessment.

I think that’s good, unfortunately not everyone does it that way. I have the feeling that everyone tries to justify their own construction method and calls it “the best.” Everything else is spoken badly of. With the Americans, the wooden method is widespread; in our area, the “solid” construction method. More wooden buildings in Scandinavian countries; in Africa, probably clay buildings. Each of these constructions has its advantages and disadvantages. I just think that the regulations in Germany will eventually take away the choice from builders. At some point, we’ll have wall thicknesses of 70 cm and more.

So concrete from a naive thought of the Castor container? — well... That formwork blocks could establish themselves for residential buildings at all was only possible because they consist of insulating materials that wrap the otherwise lousy concrete well. The current generation of formwork blocks with their exterior side of wonderfully integrated ETICS barely suffice to keep up with current standards. Therefore, one can only speak of “adequate” insulation here.

Who told you that? If you look at the pure values of the wall, then a Neopor block is actually pretty good (not to say very good). But there are skeptics for every type of construction. For example, I don’t understand a drywall — you can hardly fasten anything (not to be taken literally). But to each their own; however, one should stick to facts and not just claim things.

It seems to me that marketing romanticism got you fully caught.

Oh come on, but since this system is talked about like this here, everyone immediately knows what is meant. Although I have seen that Neopor is becoming more and more of a topic in the forums. Let’s see if I find innovations at the Munich building fair. I can hardly imagine that we can now fly to the moon, but have been building houses the same way for almost 100 years. Regards Red-Ed

I don't understand that right now.

I meant: dividing the room into two heating circuits, then each individual one has less pipe length = inertia.

By PM or email? From which area would you like views?

Here already for everyone. Many readers will surely also find interior pictures interesting, but actually even more so when finished, then in the house pictures thread. I mean when I say "views" quite classically the facades N/E/S/W.

I like that, unfortunately not everyone does it that way. I have the feeling that everyone justifies their own construction method and calls it "the best".

I take the position "an advisor is not a guardian – the decision must remain with the customer (and for that the customer must be able to weigh the facts themselves, i.e. be told in the 'source code'). The fans of "their" construction method I find understandable, what annoys me more are the hate preachers who have to classify all alternatives as "nonsense" or "devilish stuff."

Where did you hear that?

The U-value of "concrete (+ ETICS)" is worse than that of "aerated brick (+ ETICS)." I just learned about the G-value thanks to your link, until now the G-spot and the Mercedes G sufficed me.

I can hardly imagine that we can now fly to the moon,

A very poor comparison. We last landed on the moon over 45 years ago. Currently, we are no longer able to do that. And even if money were no object, we would not be able to send anyone there for at least the next 5 years.

but have been building houses the same way for almost 100 years.

Just in the last 100 years, there have been so many construction techniques that it is difficult to list them all. Through "survival of the fittest," a few have established themselves widely. Meanwhile, concepts driven by energy saving regulations are entering the market, which from an economic perspective would hardly prevail on their own.

On the topic of "autarky" from the parallel thread: Autarkic is someone who has no connection to supply and disposal networks. Everything else is and remains ideological window dressing.

Again here: I prefer generic terms, like in this example "formwork block". There are various systems of these, partly from big brands and partly from individual enthusiasts. Some of them have extensively detailed their systems into quite a number of special blocks.

The U-value of "concrete (+ ETICS)" is worse than that of "porous brick (+ ETICS)." I just learned the G-value thanks to your link, so far the G-spot and the Mercedes G have sufficed for me

Well, but that would mean I have ONE room with underfloor heating in the basement. Then I either have a level difference because of the underfloor heating to this room or a lot of wasted material in the rest of the basement.



Here are the views.

But the U-value of concrete and brick can only be compared if the same thicknesses are compared. But no one wants a concrete wall that is 37 cm thick.
With aerated concrete, that is what you do. Then insulation (ETICS) is added on top.
But if you compare a 25 cm, 36 cm, or 45 cm wall, the concrete block does somewhat better. Do you agree with me on that?

A formwork block can be many things. Whether Kaiser blocks, wooden blocks, or Neopor blocks.
Since these cannot be compared to each other, I like to call it Neopor.
