How does insulation help water pipes?
Insulating water pipes can save energy by minimizing heat loss through the piping. Insulating pipes will reduce the risk of condensation forming on the pipes, which can lead to mold and moisture damage. Pipe insulation can protect the pipes from freezing and cracking in the winter, which can cause considerable damage in the walls of the home and result in significant home repair bills for the homeowner. Studies by DOE’s Building America program have shown that distribution heat loss in uninsulated hot water pipes can range from 16% to 23% depending on the climate. Adding 3/4 inch pipe insulation can cut overall water heating energy use by 4% to 5% annually ( Backman and Hoeschele 2013 ).

In addition, cavity insulation should be installed behind the pipes, between the pipes and the exterior wall.

Why do we need insulation for pipes?
When the surfaces of plumbing pipes are cooler than the surrounding air, insulation helps control the condensation that, if left unchecked, would slowly corrode the pipes and their fittings, eventually leading to a massive failure. Though condensation may seem like a remote concern, it’s not at all uncommon, particularly when cold-water lines come into contact with warm, humid air. Special vapor barrier-wrapped pipe insulation prevents warm air from reaching the pipes.
Why is pipe insulation important?
Among the unsung benefits of pipe insulation, its ability to minimize heat gain and loss may be the most important. As water travels along the plumbing lines in a home without pipe insulation, hot water tends to lose heat and cold water tends to gain heat. Introduce pipe insulation, and you greatly diminish these otherwise inevitable inefficiencies. So in the case of a hot-water pipe, it may not sound like a big deal for the plumbing run not to lose heat, but the benefits are very real: You get lower monthly energy bills, and you don’t need to wait as long for the hot water to reach the fixtures in your kitchen or bathrooms.
