District Heating - Heat Capacity vs. Temperature
Sponsored Links
An increase in the hot water supply temperature will reduce the volume flow in a district heating system where the required heat is constant.
| Supply Temperature (oC) | Required Water Flow (liters/kW) |
|---|---|
| 90 | 28.7 |
| 100 | 21.5 |
| 112 | 16.4 |
| 120 | 14.3 |
| 133 | 11.8 |
| 150 | 9.6 |
| 180 | 7.2 |
