Notes:
1. Ratings are given in gallons per minute continuous
flow of water heated from 40°F to 140°F with 200°F
boiler water.
2. For tankless heater quantities less than maximum
allowable, it is important that water heaters be
centrally located in the boiler.
See Figure 8 for appropriate locations.
3. Tankless heater pressure drop is 5.5 PSI at
7.5 GPM.
