The pressure in the pipelines of residential buildings (regardless of the number of storeys) should not exceed 6 atm (even for metal pipes, because there is a connection and valves). Warning The parameters of the heating units are installed by another instrument – SNIP 41-01-2003 “Heating, ventilation and air conditioning”, according to which “the temperature of radiation heating panels must not exceed 60 ° C, the temperature of the carrier – not above 95 ° C”. While paragraph 3.3 SNIP 41-01-2003 reads: “The use of the coolant temperature above 90 ° C in the systems of polymer materials is prohibited. Conclusion: The appropriate use PEX tubing in a closed heating system, for example in a private house, where the maximum temperature, which gives the boiler, originally limited and can not be afraid of all sorts of crashes and accidents.
In a city where the heat flow is out of control, optimal specific heat regulating system mix with cold water, which improves the efficiency of any heating system and the period of its operation. The strong delusion, that if the steel pipe can withstand temperatures of 125 ° C, then you can forget about controlling the temperature of the carrier. But batteries, valves, heat meters, finally?
