Point of Use Water Heater Reviews

What is a point of use a water heater? For those who aren’t well-versed on anything regarding water heaters, a point-of-use water heater is just a mini water heater. There are point-of-use water heaters that contain a storage tank and those that are tankless.

Point of use water heaters are used to service around two water outlets. If you only want to heat a shower, getting a point-of-use water heater is an ideal choice to go with. They are a lot smaller than your standard-sized water heater, and that makes them perfect for use in homes and commercial properties where there is more space involved.

Point of use water heating

In most cases, a POU water heater sits close to the delivery point, for example, close to a kitchen sink or nearby a shower. Because of the proximity of the water heater to the sink or shower, you won’t have to wait very long for hot water.

With a central water heating system, the delay in getting hot water is due to water having to move through the pipes and water heater. Because these smaller water heaters are much closer, so you don’t deal with that increased delay. Most people won’t any more than a couple of seconds for nice hot water.

Don’t get mixed up between a point-of-use water heater and a hot water dispenser. A point-of-use water heater typically has a storage capacity of just under a gallon, and the temperature of the water can get hot enough to burn the skin.

Installation Of A Point Of Use Water Heater

It’s not overly complicated to install a point of use water heater. All you require is a nearby outlet so you can plug the unit in. It should only typically take you around an hour to do so. Where things will become a little more complicated is if there is no easy-to-access electrical hookup.

The smallest water heaters require a 120v outlet to stay powered. The bigger-sized units over 5 gallons will require a 240v outlet, the same type of outlet that your oven and dryer need.

You also have the option to get a gas tankless version, but keep in mind that there will be additional costs involved. You’ll have to vent the unit to the exterior of your home so that no carbon dioxide emissions will accumulate inside the house. In addition, you’ll have to get a gas line set up for the unit.

What Are The Different Types Of Point Of Use Water Heaters?

The two different types of point of use water heaters are:


Point of use water heaters with a tank have many of the same characteristics as your standard water heaters but are just much smaller. They contain a storage tank that stays at consistent temperature levels. You’ll see point of use water heaters with a tank as small as two gallons or as large as 20 gallons.

What Are Some Of The Benefits Of Point Of Use Water Heaters With A Tank?

  • Hot water arrives quickly
  • There isn’t much wastage in water because you don’t have to wait long periods for water to warm up
  • There are many different types of water heaters to pick from
  • Easy installation


With a tankless point-of-use water heater, you get a water heater that doesn’t have a storage tank but that still functions similarly to how a tankless water heater operates for your home. A tankless heater doesn’t contain any water storage, but it warms the water as required.

As a result, it uses less energy as energy isn’t being used to keep the water tank hot all of the time. One thing to keep in mind regarding a tankless electric water heater is that there is a bit of a delay when it comes to turning on the hot water and the incoming water getting hot.


  • You don’t have to worry about running out of warm water
  • You’ll save energy because water is being heated as you need it
  • A smaller tank is used

What Are Some Scenarios Where I Should Be Using A Point Of Use Water Heater?

You’re Rushing

If you’re tight for time on a particular day, using a point of use water heater will get hot water to where you need to much quicker than a traditional water heater for your home. They are much closer to the source of where you need the water, so you won’t be sitting around waiting for the heated water to get to the shower when you need to take one.

You want more Energy Efficiency

Because a point of use water heater is close to where you need hot water, you don’t have to run the tap for a long time waiting for the water to warms up, which can save you a lot of water throughout the month.

For example: If you have 40 feet of copper pipe running from your water heater in your home, water travels through that entire space of copper piping to get there. That can end up taking some time, and if you’re running the water for a while before it starts getting hot over and over throughout the day, things will add up financially after a while.

That could result in about a half-gallon of water every time you need the kitchen tap water to be heated up. It might not seem like a huge amount after one or two uses, but if you add it up throughout an entire year, that results in more than 500 gallons lost. That’s the equivalent of filling up your bathtub about 13 times and then just letting it completely drain.

Point Of Use Water Heater For Showering Purposes

If you want a point of use water heater for showering, there are many things to keep in mind. The first thing you must determine is how many people use the shower in a certain period. The average shower takes about 14.9 gallons of water, and the storage size is 2.5 gallons.
