Do I need to wrap my water heater pipes?
Insulating your hot water pipes reduces heat loss and can raise water temperature 2°F–4°F hotter than uninsulated pipes can deliver, allowing you to lower your 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.
