Due to the high quality of construction and reliable thermal insulation of buildings, as well as the use of local or autonomous heat supply facilities, the temperature of the coolant decreased to 90 degrees. As a result, it became possible to use a plastic pipeline instead of steel. The use of many pipes from plastic ones is due to working parameters: radiation heating of the panels is not more than — 60 ° C, the maximum heating of the coolant is 95 ° C.
