Point-of-use water heaters can be added to a home’s existing plumbing without the need to re-do the whole plumbing system. The name describes a small device that heats water very close to the point where it’s used, such as a sink, shower, bathtub or washing machine.

A POS water heater provides a great solution for those who don’t like waiting several minutes for hot water to get to the tap. The different types of equipment available, potential energy savings, and lifetime cost can affect the price of a water heater, so check with your local retailer before you buy.

The importance of hot water in our homes is a cornerstone of the modern world. We need to make sure our water supply is reliable, affordable and abundant.

The U.S. Department of Energy says homeowners can achieve energy savings of up to 50 percent by using a point of use heater at each hot water outlet. POS tank water heaters typically last 10 to 15 years, while tankless water heater can last up to 25 years. You can expect to pay $400 – $800 for a point-of-use water heater, including installation, whether it’s tank-type or tankless. If you are planning to move to a new home within a year or two, you won’t save enough money on your utility bills to offset the cost.
