Electric heating is very expensive compared with mains gas.
The reason the UHF pipe loses heat is that its job is to do just that and to lose its heat and give it up to the floor.
Rads assume a flow of 70° and a return of 50° to operate with a condensing boiler most efficiency and to give out close to the rated heat output.
You would need rads at least twice as big if you wanted a flow temperature of 50°.
Any pipe will lose heat but to do that most efficiently and get 100w/m² you do need to install it in the normal way, ideally with the pipes burried in concrete or at least having metal spreader plates.
Dont expect plumbers to be pulling the wool over your eyes. Their skill levels will vary but thats the same in amy profession.
