How to find the right Hot Water Heater Capacity

You need to consider flow rate to find the right capacity. This will tell you how much hot water your machine can comfortably produce on demand. You can calculate your required flow rate (usually expressed in gallons per minute, or GPM) by thinking about what sorts of water fixtures you plan on running simultaneously and then adding up all their individual flow rates. Here’s a helpful list of the flow rate for common fixtures.

  • Standard Dishwasher: 2 GPM
  • High-Efficiency Dishwasher: 1 GPM
  • Faucet: 1 GPM
  • Shower: 2 GPM
  • Rain Shower Head: 5 GPM
  • Standard Washing Machine: 2.5 GPM
  • High-Efficiency Washing Machine: 1 GPM
