Fig. 1 shows the heating circuit of a pumped central
heating system: The burner [2] heats the water inside
the boiler [1]. This heating water is transported by the
pump [3] through the flow line [4] to the radiators [6]. The
heating water flows through the radiators, and in doing
so, gives off some of its heat. The heating water flows
back to the boiler via the return line [7], where the cycle
starts again.
The room temperature can be adjusted to your personal
requirements using the thermostatic radiator valves [5].
All radiators are supplied with the same flow
temperature. The heat transferred to the room depends
on the radiator surface and the heating water
throughput. Therefore, the heat transfer can be
manipulated via the thermostatic radiator valves.
What determines the heat demand of a room?
The heat demand of a room largely depends on the
following factors:
– Outside temperature
– Required room temperature
– Type of construction/insulation of the building
– Wind chill factor
– Solar radiant energy
– Internal heat sources (open fireplace, occupants,
lamps, etc.)
– Closed or open windows
Take these factors into consideration to achieve
a comfortable room temperature.
