Link error, the correct is http://en.wikipedia.org/wiki/District_heating

District heating in Denmark are hot water systems limited to a
temperature of 130 degrees C and a pressure of 6 bar(gauge). Normal
forward temperature from the heating plant is 80-90 degrees C and normal
return temperature is appr. 40 degrees C.

Normally district heating pipes are laid in the roads and streets and
sets of pipes for each house are branched off. In the house the set of
pipes enters a heat exchanger which supplies energy for room heating and
domestic water heating. This way the high-pressure district heating
water is not used in the internal curcuits of the houses.
