Sizing for Peak Performance
Oversized units raise upfront costs without proportional benefits, while undersized units lead to temperature fluctuations or flow starvation. HEP’s sizing calculus hinges on:
- Fixture count multiplied by average fixture flow rate.
- Simultaneous usage scenarios (two showers plus washing machine, for example).
- Desired output temperature, taking into account seasonal variations in incoming water temperature.
Sample Calculation
An Old Fort property with two full baths, each delivering 2.0 GPM at the showerhead, a kitchen faucet at 1.5 GPM, and a washing machine drawing an average of 1.5 GPM may require:
- Peak flow: 2.0 + 2.0 + 1.5 + 1.5 = 7.0 GPM
- Desired rise: Winter inlet at 50 °F, target 120 °F → 70 °F rise
- Unit specification: Minimum 7.0 GPM at 70 °F rise
HEP reviews manufacturer charts to confirm the chosen model can achieve the necessary output at local altitude and gas composition variables.
