120v point use of water heater

Water heaters are the appliances that make your life much easier. Without them, it would be hard to bathe in warm water or even cook with hot water.

What is a Point of Use Water Heater?

A Point of Use (POU) water heater is basically a smaller version of the conventional tank-type or tankless water heaters. It works by heating up water and supplying it directly to fixtures such as sinks, showers, and faucets.

They are very efficient because they heat the water so close to the point of use, hence their name. This means minimal heat is lost through the piping. Many people will use them as a hot water booster for showers in large homes.

There are two types of electric POU water heaters: 120 volt models and 240 volts models. 120 volts POUs are usually referred to as “low watt” because they have lower power ratings than their high-watt counterparts. 120 V low watt units will not be able to output as much hot water per minute as the higher voltage water heaters. You can also find storage point of use heaters and instant.
