For Electric & Natural Gas Customers
For maximum water efficiency to reduce your electric or natural gas hot water heating cost, select a shower head with a flow rate of less than 2.5 gpm.
There are two basic types of low-flow showerheads.
- Aerating showerheads mix air with water, forming a misty spray.
- Laminar-flow showerheads form individual streams of water. If you live in a humid climate, you might want to use a laminar-flow showerhead because it won't create as much steam and moisture as an aerating one.
If you have a showerhead that was purchased before 1992, some showerheads had flow rates of 5.5 gpm. Here's a quick test to determine whether you should replace a showerhead:
- Place a bucket, marked in gallon increments, under your showerhead.
- Turn on the shower at the normal water pressure you use.
- Time how many seconds it takes to fill the bucket to the 1-gallon (3.8 liter) mark. If it takes less than 20 seconds to reach the 1-gallon mark, you could benefit from a low-flow showerhead.
