What Size Tankless Water Heater Do I Need for My Spokane Home?

When it comes to upgrading your home’s hot water system, tankless water heaters are an increasingly popular choice among homeowners in Spokane Valley, WA. Mainstream Electric, Heating, Cooling, & Plumbing, a trusted name in the Inland Northwest since 2000, is here to help you determine the perfect size tankless water heater for your home.

Factors to Consider When Sizing a Tankless Water Heater

To ensure you select the right size tankless water heater, Mainstream’s expert plumbers consider several key factors:

  1. Number of Simultaneous Users: How many people will be using hot water at the same time? A larger household with multiple bathrooms may require a higher capacity unit.
  2. Flow Rate: The flow rate, measured in gallons per minute (GPM), determines how much hot water the unit can deliver. Consider the flow rates of your fixtures, such as showerheads and faucets.
  3. Temperature Rise: The temperature of the incoming water supply and the desired output temperature affect the size of the tankless water heater needed. In Spokane Valley, where groundwater temperatures can be quite cool, a higher temperature rise may be necessary.
  4. Energy Efficiency: Tankless water heaters with higher energy efficiency ratings can provide the same hot water output with a smaller unit size.

Mainstream’s Sizing Recommendations

Based on our extensive experience serving the Greater Spokane area, Mainstream typically recommends the following tankless water heater sizes:

  • For 1-2 person households: A unit with a flow rate of 5-7 GPM
  • For 3-4 person households: A unit with a flow rate of 7-9 GPM
  • For 5+ person households: A unit with a flow rate of 9+ GPM

However, every home is unique, and our expert plumbers will assess your specific needs to determine the ideal size for your tankless water heater.
