District Heating - Heat Capacity vs. Temperature
Water temperature and heating capacity.
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 |
