Hello,
Yesterday, we were recommended a dry underfloor heating system from PYD, supposedly top of the line and reasonably priced. It wasn’t really a formal consultation; the electrician was actually there to plan the house’s electrical system, but we ended up talking about heating. He said he has already installed this underfloor heating for several customers, and they are all very satisfied. According to him, the advantages—especially since we are renovating an older building—are less installation work and less weight compared to the conventional wet system, no drying time, better heat distribution (not only the floor is warm, but the entire room) thanks to these aluminum/pyramid plates, and also lower energy consumption.
Does anyone have experience with such an underfloor heating system? Are there any significant disadvantages? Has anyone used the PYD underfloor heating?
Thanks in advance.

Hello questioner,
before you receive only general half-truths and guesses in response to your question:
I cannot say whether it is a disadvantage, but these electric heating systems work best with a rigid floor covering, meaning tiles.
There are electric heating systems designed for laminate floors as well, but in those cases, all components are coordinated with each other.
The heating output of a thin electric heating layer is immediately available because only the adhesive mortar and ceramic tiles have to be heated—not a 45mm (1.8 inch) thick screed layer as well.
Since the system is controlled by room thermostats, these systems function as room heating, or, if the heating elements are spaced quite far apart, “only” as floor warming (room heating is then technically provided by other means).
As for “disadvantages,” nothing comes to mind except for the electricity bill.
But other energy sources (in Germany) are not much cheaper either.

Best regards and wishing you a good decision. KlaRa

say, but such electric heatersI have to correct you. This is a classic water-based underfloor heating system (with 20/2 mm (approximately 3/4 inch) pipes, if I read it correctly at a glance).In addition to the pipes, there are also heat conduction plates and either a wet or dry screed.
Regarding my last post, I must apologize and thank "nordanney" for the correction.
(normally, I would have deleted my post again)
It is correct that the PYD thermal system is a warm water underfloor heating system and not, as I mistakenly assumed, an electric foil system.

Then again to "HitaG093":
You probably meant the "XY-FLOOR dry system".
In this system, heat distribution plates are placed on the installed heating elements.
Finally, dry screed panels are used as the substrate for the final floor covering.
This certainly works, but only if you have the necessary installation height available for this retrofitted underfloor heating.
You need battens about 50mm (2 inches) high, with the load distribution layer on top. This should be at least 19mm (3/4 inch) thick.
So, in total, you are looking at around 7cm (2 3/4 inches) of build-up height plus the floor covering.
If this much height is available, the system can be installed on old (evened) wooden floorboards or a raised floor (in the installation video, an existing wood chipboard layer).
Apart from the required build-up height, no disadvantages are apparent at first.
If this height is lacking, a system panel (for the heating elements) could be used, for example, above an evened screed. This panel is embedded only 5mm (3/16 inch) above the pipe top edge with an elastic (mineral) leveling compound.
The new floor covering is then installed either floating or glued on this.
This system requires only a very low build-up height, and bonding is possible without an additional load distribution panel.
