3.3 District Heating
District heating is generated in a centralized
location and distributed to residential and
commercial use.
Recommendations:
• min. 40 °C supply temperature at the valve.
• sucient heating capacity to increase the
room temperature with 1 °C per hour.
• only radiator valves approved for Danfoss
adapters.
Weather compensation / ECL
If the boiler’s heating curve is set to have the
radiator thermostats on comfort temperature
constantly, the curve must beincreased
in order to be able to raise the room
temperature after a setback period.
• If the setback periods are long, further
increase might be necessary.
• If the economy periods are short, less
increase can be sucient.
