Is ceiling heating possible as an acoustic ceiling?

In my living room (extension, with many exterior walls) an acoustic ceiling is actually planned to minimize echo. For this, I was thinking, for example, of these wood + felt modules that have been available for a few years or even the more visually appealing wood modules from Lignotrend. Unfortunately, the floor area is not sufficient to heat the room (higher heating load of ~55W/m² compared to the rest of the house with an average of about 30W/m²). Since the only large wall is to be exposed concrete, wall heating is not possible there. At most, in the rear area of the room. Are there also ceiling heaters that have an acoustic effect and are visually (wood?) appealing?

Yes, there are plasterboard ceilings with perforated panels and heating or cooling technology behind them. The perforated panels can also be covered with acoustic plaster, resulting in a uniform, closed surface again. Whether the required acoustic properties are achieved with such a construction must be assessed by an acoustician if in doubt.

However, I only know of systems used in commercial buildings. To what extent these are used in single-family homes and which systems, I cannot say.

Thank you for your reply. There is no acoustician since it is a single-family house. Since the living room consists of many glass surfaces and concrete surfaces, something has to be done so that this room can really be used as a living room. Can you recommend an affordable system for ceiling heating?

Unfortunately, the floor area is not sufficient to heat the room (higher heating load of ~55W/m² compared to the rest of the house averaging about 30W/m²).

As already mentioned in the other thread (why is there no progress there? You have received enough input showing that the floor area is sufficient – but you somehow do not want to hear that, right?), you still have homework to do.

to minimize echo as much as possible.

What common measures have you planned? (Carpet, decorations, plants, pictures with absorbers, etc.) Have you had the room acoustics calculated yet?

There is no acoustician because it is just a single-family house.

I do not understand the connection between acoustician and "it is just a single-family house." Whether I measure an office room or an extension does not matter.

As already mentioned in the other thread (why is it not continuing there? You have received enough input that the floor area is sufficient -

When I look at tables, etc. here, a heating load of ~55W/m² is not a problem, as long as the flow temperature is correspondingly high. So higher than 35°C. See for example here:

If I roughly calculate here with 75mm installation spacing, I cannot manage with 35°C flow temperature. Also, the Trechnchplaner tool (in conjunction with flow30) indicates that the area is not sufficient.

I just want to avoid having to operate the heat pump at high flow temperatures in the end and having to throttle the valves in the rest of the house, where the heating load per m² is not so high, so that it doesn’t get too warm.

Therefore my consideration of a ceiling heating.

What normal measures have you planned? (Carpet, decoration, plants, pictures with absorbers, etc.) Have you already had the room acoustics calculated?

I actually want to avoid a carpet because hair gets stuck there very quickly. Yes, there will be some plants. For absorbers on the wall, unfortunately I only have the small rear wall and the front wall, on which I don’t want to place 10cm thick pictures. As already mentioned, I don’t have an acoustician. That would again be significant costs that would burden the budget framework even more currently. But it should be clear that something needs to be done in such a room.

That is all not true. You have seen my own plans. And calculate not with 75mm, but with 50mm. With no more than 30 degrees flow, you get sufficient performance.

And once again: LET THE HEATING BE PLANNED EXTERNALLY and don’t fiddle around yourself without knowledge.

But it should be obvious that something needs to be done in such a room.

No, it actually is not if furniture is added.

I actually want to avoid a carpet, because hair tends to stick there very quickly.

Tip: vacuum cleaners have been around for over 120 years.

on which I don’t want to place 10cm thick pictures.

Then no acoustic ceiling will help either. That is only one possible component.
And acoustic panels are not 10cm thick either. 3-4cm is sufficient. So only a bit thicker than normal pictures.

And again here: Don’t try on your own if you have no idea. Go to a professional.

As already mentioned, I don’t have an acoustician.
That would mean considerable costs again, which would further strain the budget.

You have to choose one:
- Messing around with expensive ceiling constructions or other self-planning with the high chance that you mess it up alone and throw money away (which you actually don’t have)
or
- spend about 150-200€ for an online measurement (you provide the room data) and acoustic planning, or 500-750€ for an on-site measurement and planning
