Heating and Cooling

To select the right water heater for your home, you need to consider the size of your family and other factors that contribute to your Peak Demand Output Requirement. The chart at right follows standard industry guidelines for residential sizing.

To Choose the Right Water Heater for You...

1. Determine whether your family is Low Demand or High Demand.
You should consider your family to be High Demand if...

• There are more than two full baths in the home.
• There are (or will be) teenagers living in the home. It's a fact: teenagers use more hot water for showering and washing clothes.
• If you have an oversize whirlpool bath or other large tub. As a rule of thumb, the water heater tank capacity should be 100% or more of the bathtub capacity (example: 75-gallon tub/80-gallon water heater).

2. Find your Family Size and Peak Demand Output Requirement in the chart above.

3. Consult the charts on the preceding pages for a State residential electric water heater with a Peak Demand Output that meets your requirement.

4. If your family is High Demand, you should step up to the next Peak Demand Output level.
