Tankless Water Heater Sizing for Maryville Homes
The sizing process is pivotal; an undersized system leads to fluctuating temperatures, while an oversized unit inflates upfront costs without tangible benefits. HEP follows a granular procedure:
- Count simultaneous hot-water fixtures (showers, dishwasher, washing machine).
- Measure flow rates at each fixture using calibrated meters.
- Determine groundwater temperature averages in Maryville (around 57 °F).
- Calculate required temperature rise to hit 120 °F–125 °F delivery.
- Select a unit with the appropriate gallons-per-minute (GPM) rating.
Example Calculation
- Two showers at 2.0 GPM each = 4.0 GPM
- Kitchen sink at 1.5 GPM running concurrently = 5.5 GPM total
- Desired temperature rise: 63 °F (from 57 °F to 120 °F)
- Unit selected: 6.5 GPM at 70 °F rise for buffer margin
