- Estimate the flow rate in gallons per minute (GPM).
Example flow rates:
| Appliance | Flow Rate (GPM) |
|---|---|
| Shower | 1.5-2.5 |
| Dishwasher | 1-2 |
| Washing Machine | 2-2.5 |
Sum the flow rates to find the total GPM needed. Select a model that meets or exceeds this total.
Energy Efficiency Ratings
Energy efficiency ratings help you save money and the environment. Look for models with high efficiency ratings.
Consider the following ratings:
- Energy Factor (EF): Measures overall efficiency. Higher EF means more savings.
- Uniform Energy Factor (UEF): Newer standard. Higher UEF indicates better performance.
Look for models with the ENERGY STAR label. These models meet strict efficiency guidelines.
Choosing an efficient model saves on energy bills. It also reduces your carbon footprint.
