ᐅ Underfloor heating with aluminum composite pipe or plastic piping

nils1985Hello,
Yesterday, we spoke with a contractor about our new build. I would guess he is from the old school (30 years running a masonry business).
He recommended a heating system with solar panels, a heating panel (I assume he means the heat exchanger), and a 300L (79 gallons) buffer tank. The underfloor heating pipes he uses are made from an aluminum composite pipe rather than plastic. He said that plastic pipes eventually draw in air. That sounds interesting at first, but he mentioned a supply temperature of 60–65°C (140–149°F) for the aluminum pipes. That seems quite high.
How should this statement be assessed?
Aren’t plastic pipes usually operated at around 35°C (95°F)? That would mean higher heating costs with the composite pipes.
Thank you for your evaluation and explanation...
Best regards

At first, you tend to believe a lot and don’t know enough for such an investment.
The pipe does not determine the supply temperature; rather, it is the heat loss of the house influenced by the floor construction and the pipe spacing.
I would be skeptical about the air issue.
Aluminum composite pipes are not wrong either and will ultimately operate at the same maximum 35°C (95°F) design temperature as braided fiber with silicone sealing.
