Do you want to save your energy costs? We know all of you must want low energy bills for your water heaters. But, a lot of you may not know how to do it. So, our professionals decided to tell you about a unique device that can save your energy costs. And that device is: Point of Use water heater.

We are going to discuss this Point of Use Water Heater.

What is the Point of Use Water Heater?

A point of use (POU) water heater is a small unit that can be installed near the showers, faucets, sinks, tubs, or a washing machine. They are compact so you can easily install them wherever you want warm water.

So, what does this device do? The point of use water heater heats water near the place where it is needed. So, you don’t need to wait for hot water from the central heating system after opening the faucet.

You all know that if your faucet is at a distance from the central heating system, it will take a lot of time to reach its destination. But, a point of use water heater will heat cold water near your faucet and will give it to you in a short time.

There are two types of point of use water heaters.

Two Types of a Point Of Use Water Heater

This water heater has two types. 

1. Point Of Use Tank Water Heater

These look like the mini version of the tank water heaters. You can find them in different sizes ranging from 2.5 gallons to 20 gallons. 

Because of their compact size, you can install them near every typical water outlet.

2. Point Of Use Tankless Water Heater

These work just like the big tankless water heaters. It means they don’t store water either. So, they are smaller than point of use tank water heaters.

But, they are slightly more inconvenient than the tank heater. One inconvenience is you have to wait for some moments for the warm water to come. It is not as much as you have to wait for warm water from the central system, but a bit more than a mini tank heater.

The second inconvenience is it is only available for three places:

  • Wall mounted
  • Over sink
  • Under sink

So, this is a brief introduction to the point of use water heater. Now, how is it energy-efficient?

Is Point Of Use Water Heater Energy Efficient?

The simple answer to this question is “Yes”. A point of use water heater is energy efficient. How? Let’s see it.

  • When you turn on a faucet, you wait for warm water to come out. Cold water is getting wasted while you are waiting. Almost 2-5 gallons of water is wasted per minute during this waiting period. So, your point of use water heater can eliminate that time, preventing cold water from getting wasted.
  • When water moves in the pipe from the central heating system to your faucet, a lot of heat is wasted in the journey. So, you will not be able to get as much warm water as you desire. But, this water heater will heat water near your faucet, so no heat will be wasted and you can enjoy a really warm bath.
  • It happens that when you open a faucet, the central heating system warms excessive water and it goes into the pipes. When you close the faucet, some of the warm water remains in the pipe and gets cold when it is not used. This cold water comes out initially when we turn on a faucet. If you have a point of use water heater near the faucet, it will re-warm that cold water, saving the energy that the central heating system uses on it.
  • Tankless point of use water heater only warms water when you want to use it. It works differently than the central heating system which always has warm water in its system. So, it can also save your energy by warming only a small amount of water.

These are the ways through which a point of use water heater is energy efficient. There are some interesting facts and research related to its energy efficiency too.

Facts Related to Point Of Use Water Heater Energy Efficiency

A lot of credible sources confirmed that a point of use water heater can make your life easy in terms of low energy bills.

The US Department of Energy (DOE) claims that electric water heaters take 18 percent of your home’s total electricity bill. And, they also say that you can save 50 percent of water heater energy if you use it at each of your outlets. It means you can save almost $100 annually when using this heater.

The Energy Star Initiative also says that you can take advantage of a point of use water heater even if you have a central heating system. It will still be useful in lessening your energy and water costs.

The U.S. Environmental Protection Agency says that a family spends over $1000 annually on water costs. But, they can save almost 20 percent if they use water-efficient fixtures. It means that POU can save your money on water too.

The DOE also says that investing money in POU water heaters is a wise decision. The tank point of use water heater can last for 10-15 years, and the tankless one can have the age of 20-25 years. 

It means that buying it will not be an expensive decision for you. You can also install them easily if you know the basics of plumbing. If not, then their installation from a professional person will also not be costly.

However, the decision to install them is always not a favorable one. There are certain situations in which a point of use water heater can give you benefits.
