Insulate your water pipes
Uninsulated pipes waste a lot of heat. Paying someone to insulate your pipes may make financial sense. Uninsulated water pipes in or near exterior walls might rupture in freezing weather, which can be disastrous. It is well worth the effort to have insulation installed during new home building, during any work on your water heater or pipes, or to insulate the pipes yourself. Special circumstances, such as when the fuel used to heat water is very expensive, the distance traveled by the pipes is long, the pipes are exposed to very cold air, and the home consumes a lot of water, can result in much higher energy savings. In these cases, cost savings may offset paying for someone to do the job for you.
Insulating your hot water pipe can help you save a lot of heat and electricity. Insulating your hot water pipes lowers heat loss and can boost water temperature 2°F-4°F higher than uninsulated pipes, allowing you to lower the temperature setting. You'll also get hot and warm water from your faucet faster. You'll also save water by not having to wait as long for hot water when you switch on a faucet or showerhead.
