Calculating BTUH Output for Different Water Temperatures
The BTUH outputs are listed for 180° water. The following chart may be used to calculate the BTUH outputs for different water temperatures:
| Water Temperature | Multiply the Listed BTUH output (180°) by: |
| 120° | 0.38 |
| 130° | 0.48 |
| 140° | 0.57 |
| 150° | 0.67 |
| 160° | 0.78 |
| 170° | 0.89 |
| 180° | 1 |
| 190° | 1.13 |
To size the radiators it is necessary to calculate a house’s heating requirement. This calculation measured in BTU/Hour should be done on a room-by-room basis either by a heating contractor or qualified plumber. The following are some estimates of Heat Requirements for Sample Cities:
| City: | BTUH per sq. foot: |
| Boston | 40 |
| Chicago | 40 |
| Denver | 40 |
| New York City | 40 |
| Philadelphia | 35 |
| Portland, OR | 25 |
| San Francisco | 25 |
| Seattle | 25 |
| Toronto | 40 |
| Washington, D.C. | 35 |
