PYD Underfloor Heating Experiences

Hello,
yesterday we were recommended a floor heating system (dry) from PYD, supposedly the ultimate and reasonably priced. It was not really a consultation, actually the electrician was there for planning the house's electrical system, but we got onto the topic of heating and he has installed this floor heating for several customers, and everyone is totally enthusiastic. According to him, the advantages especially for renovating an old building are less application and less weight than the normal wet version, no drying time, better heat distribution (not only the floor is hot, but the room) thanks to these aluminum / pyramid panels and also less energy consumption.
Does anyone have such a floor heating system? Are there any significant disadvantages? Has anyone had experience with the PYD floor heating?
Thanks in advance.

Is not a miracle heating. Either classic under screed or as a usual dry system.

Hello questioner,

before you only receive generalized half-truths and assumptions in response to your question: Whether it is a disadvantage, I cannot say, but such electric heaters work best with a rigid top layer, which means tiles. Although there are also electric heating systems for laminate floors, all components in those are coordinated with each other. The heating output of a thin electric heater is immediately available because only the adhesive mortar and the ceramic tiles, but not a 45mm thick screed layer, have to be heated. Since the whole system is covered by room thermostats, these systems function as room heating, or if needed with very coarse spacing of the heating elements, also "only" as floor warming (the room heating is then technically taken over otherwise). Apart from the electricity bill, I cannot think of any "disadvantages." But other energy sources are (in Germany) not much cheaper either.

say, but such electric heaters

I have to correct you. This is a classic water underfloor heating system (with 20/2 pipes, if I read it correctly at a glance). In addition to the pipes, there are also "heat conduction plates" and the 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 heating system is a warm water underfloor heating system and not, as I mistakenly assumed, an electric foil system. --------------- Then again to "HitaG093": You surely meant the "XY- FLOOR dry system". There, heat distribution plates are laid on the installed heating elements. Finally, dry screed elements are used as the installation base for the top covering. The whole thing certainly works, but only if you have the necessary build-up height available for this subsequent installation of underfloor heating. You need the battens with about 50mm height, then the load distribution layer on top. This should not be less than 19mm thick. This gives us around 7cm height plus the top covering. If that much build-up height is available, the system can be used on old (levelled) wooden floorboards or a suspended floor (in the installation video, an existing chipboard level). No disadvantages are initially apparent apart from the necessary build-up height. However, if this is lacking, for example above a levelled screed a system board (for the heating elements) would be conceivable, which is then embedded only 5mm above the pipe edge with an elasticized (mineral) leveling compound. On this, the new top covering is then installed floating or glued. This system only requires a very low build-up height and bonding is possible without an additional load distribution plate. ------------- Sorry for the initial confusion: KlaRa
