Real flow rate by climate
A tankless heater's usable flow depends on how far it must raise incoming water temperature. Sustained hot-water flow of the Vesta VRP PLUS-150 (VTP-150) at common temperature rises (a typical shower uses about 2 GPM of mixed water):
| Temperature rise | Climate | Sustained flow | Simultaneous showers |
|---|---|---|---|
| 45 °F | Warm climate (~75 °F groundwater) | 4.7 GPM | 2 |
| 55 °F | Mild climate (~65 °F groundwater) | 4.7 GPM | 2 |
| 70 °F | Cold climate (~50 °F groundwater) | 4.1 GPM | 2 |
| 77 °F | DOE test condition | 3.7 GPM | 1 |
