ᐅ Manufacturer of underfloor heating dry system

Hello!

We have purchased a house and are currently planning the renovation. We would like to install underfloor heating, but embedding it in the screed is not an option.
We are considering a dry system retrofit, as it seems to be the simplest solution at first glance. However, we are unsure which manufacturer to choose.
Does anyone have experience with the different manufacturers, or maybe personal experience they could share with us?

Thank you very much in advance for your answers!

Best regards,
Philipp

Why not? I just installed underfloor heating in the screed myself. Then new screed on top. Total build-up height 65mm (2.6 inches).

I looked into it but concluded that a conventional system is better for me. Build-up height and cost were the deciding factors for choosing a conventional underfloor heating system.

The problem is that this is a two-family house, and the apartments are already nearly two centimeters (0.8 inches) higher than the stairwell. If I add another 65mm (2.6 inches) of screed in the apartments now, there will be almost an 8cm (3.1 inches) difference in height compared to the stairwell. We didn’t want to renovate the stairwell for the time being, as it is still fairly new.

May I ask how much you paid per square meter (square foot) approximately?

What matters more is whether the ceiling height allows for adding another layer inside the apartment. I would actually find an 8 cm (3 inch) step almost more practical than a 2 cm (1 inch) step.

However, it also needs to be checked if the structural engineering can support the additional weight.

Alternatively, the old screed could be removed.

Hmm – how about removing the old screed first? There must be something applied on the raw subfloor.

For 120sqm (1,292 sq ft) I installed about 1,600m (5,250 ft) of underfloor heating pipes (MSV pipes) with a total of 15 circuits. Beneath the underfloor heating there is 2cm (0.8 inches) of WLG22/23 PUR insulation (which is fine, since my basement ceiling will also be insulated). The screed is a traditional cement-based screed including steel fibers (which don’t really add much) and an accelerator (the screed was ready for covering after just over one week).
Partly DIY, partly contracted out.
Costs including gutting and disposal amounted to about €70 per sqm – so from “removing the floor” up to the point “ready for the tile and parquet installers.” Oh, and almost half of the costs went into gutting (which also included demolishing two bathrooms and one wall).

May I ask about the additional cost here?
