Underfloor heating

Hello everyone,
we received a first offer from our heating engineer today.
The underfloor heating is supposed to be from U.....OR.
Are there actually big quality or price differences in underfloor heating??
I mean, hopefully you don’t see the thing ever again anyway....
By the way, the offer was not for a system where the pipes are laid in a grid but one that is stapled...
Better / worse is the question....

Hello,
my layman's opinion...
We decided against various grid or knob systems and opted for a stapler system. I see the main advantage in the fact that the screed can lie on the pipe with a larger surface area, resulting in better heat transfer. With the right tools, a friend and I laid the pipes throughout the entire house and connected them to the heating circuit distributor within 12 hours.
I'm not entirely sure about the price anymore, but I believe the stapler system is cheaper; however, it requires a bit more time for installation than the click systems.

There are practically no price and quality differences, it's all just plastic anyway, it depends on a clean installation with appropriate spacing...
