By using less hot water, you’ll save energy and save money on your water bill. For maximum water efficiency, select a shower head with a flow rate of less than 2.5 gpm. Choose faucet aerators – the screw-on tip of the faucet – that have flow rates of no more than 1.0 gpm. When replacing an aerator, bring the one you're replacing to the store with you to ensure a proper fit.

Insulating your hot water pipes reduces heat loss and can raise water temperature 2ºF–4ºF hotter at the faucet or showerhead than un-insulated pipes can deliver, allowing for a lower water temperature setting. You also won't have to wait as long for hot water when you turn on a faucet or showerhead, which helps conserve water.

Insulate all accessible hot water pipes, especially within 3 feet of the water heater. It's also a good idea to insulate the cold water inlet pipes for the first 3 feet.

Capture the heat from your shower drain with a drain-water heat recovery system to reduce the energy needed to heat your water. Any hot water that goes down the drain carries away energy with it. That's typically 80–90% of the energy used to heat water in a home. Drain-water heat recovery systems capture this energy to preheat cold water entering the water heater or going to other water fixtures.

Electric water heaters are one of the largest energy users in most homes. Supplementing your existing system with a solar hot water (SHW) system is a wave to save on energy costs. A SHW system preheats the water that goes into your existing water heater and reduces the amount of electricity your water heater consumes by 50 to 70 percent.
