With a point of use electric water heater, you can enjoy hot water at an affordable price without sacrificing quality or convenience.

What Is Point Of Use Electric Water Heater

Point of use water heaters can drastically reduce the time for hot water to reach the tap after you open it. The waiting time depends on the distance between the tap and the water heater. The more distance it needs to go through, the more time it will take.

One way to avoid long wait times for hot water is to install a point-of-use water heater. As the name implies, this device warms up water near a sink, shower, tub, or washing machine.


This type of water heater is common in areas with a high need for hot water. It is sometimes referred to as an “on-demand point of use water heater”, “POU water heater”, “point of service water heater”, or “POS water heater.”

It is possible to install a point-of-use water heater to an existing home’s plumbing setup without replacing the whole system. These POU heaters are generally relatively small and can be situated beneath a kitchen sink or bathroom sink.

If you don’t want to wait for your hot water to reach the faucet (and incur extra costs from squandering usable water), then a point-of-use water heater is an ideal solution. Determine if this is the correct answer by examining the different kinds of gear on the market, potential energy savings, and the total expense you’ll pay over the long haul.

Point Of Use Electric Water Heater And Instant Hot Water

Domestic hot water is an essential element of contemporary living. Houses are typically supplied with either a tank-style or tankless water heater, though some dwellings have hot water taps that are too far from the heater to get quick access to hot water.

An increasing number of house owners are starting to opt for point of service water heaters due to their extra comfort, ease of use, and energy efficiency.

You can probably relate to the experience of standing in the shower, shivering, while you wait for the warm water to come out of the tap.

When you stand under the shower and wait for the water to become hot, all the cold water that is gushing out is the one that has been accumulating in the length of the pipe between your water heater and the showerhead. To reduce the wait, you must decrease the distance it must travel.

Types Of Point Of Use Electric Water Heater

As with water heaters made to service a full residence, point of use heaters can either have a storage tank or be tankless.

Point Of Use Tank Water Heater


This water heater functions like any other traditional water heater. It has a substantially smaller tank meant to heat water in one or two locations. The tanks of these heaters generally hold anywhere between 2.5 and 20 gallons. These systems remove the space between the heat source and the tap, allowing immediate hot water.

Point Of Use Tankless Water Heater


When you turn a faucet or push a button, a tankless heater at the tap will immediately activate, so you won’t have to wait long for your hot water. Wait only for a few seconds. Tank-type POU heaters are more efficient than their tankless counterparts, resulting in a significantly shorter wait time for hot water. Moreover, tankless water heaters occupy less space than those with an attached tank.

Is Point Of Use Electric Water Heater Energy Efficient?

It is simple to answer this question. Whether your point of use water heater is powered by electricity or gas, or if it has a tank or is tankless, it is always an environmentally friendly option.

A point-of-use water heater can prevent extra water from being flush down the drain while the hot water travels from a far-away water heater. It is normal to wait for a few moments before taking a shower, and since a standard shower uses 2.5 gallons of water for every minute, the amount of water that goes to waste can be huge.

Before the tap was shut off, the warm water that came out initially was heated by the water heater and sent out to the pipes. The energy expended to warm up the water is not utilized correctly once the requirement for hot water ceases, as the water cools off in the pipes. This is an inefficient use of both water and energy.

Domestic water heating systems are the second most significant household energy consumers. According to U.S. Department of Energy, electricity-powered water heaters can account for nearly one-fifth of a residence’s total electricity expenditure. Lowering the quantity of squandered water and energy will lead to decreased utility costs.

Will A Point Of Use Electric Water Heater Save Money?


When people learn about the advantages of having a point of use water heater in their house, many get intrigued. It can be a simple decision for those who want to experience extra comfort and convenience.

When budgeting, you need to consider the expense of acquiring and installing a point-of-use hot water heater. 

Point-of-use tank water heaters usually have a lifespan of 10-15 years. In contrast, tankless water heaters can go on for as long as 25 years, which gives you plenty of time to recover what you paid for the POU heater and its installation through lower utility bills.

The expense of installing a point of use water heater (tank-type or tankless) is between $400 and $800, which is dependent on the layout and state of the current plumbing system.

According to U.S. Dept. of Energy, property owners can drastically reduce their energy consumption by installing a point-of-use water heating system at every water source. This could lead to energy savings of up to 50%.

If you are thinking about relocating within 1-2 years, you will need more money to save from your utility payments to cover the cost of buying a unit and putting in a point of use heater. As point of use heaters are becoming increasingly in demand, they could be an attractive feature for potential buyers of your house.

Point Of Use Electric Water Heater Maintenance

Point of use water heaters are miniature models of whole-house heaters and, similar to those, they necessitate constant upkeep. 

It doesn’t matter if a POU water heater is of the tank or tankless variety. Its optimum performance and lifespan can increase only if it is kept up with the proper upkeep.

People who own their own homes can take care of specific upkeep duties for water heaters, but a certified plumbing expert should only do other jobs.

How To Find The Best Point Of Use Electric Water Heater

With the growing requirement for POU water heaters, many firms are now producing them, providing people with a wide variety of brand choices.

It’s beneficial to have a wide variety of options, but when there are so many different brands to pick from, it can be challenging to decide which is the best match for you and your needs, no matter if you’d rather have tankless or tank-type.

Before examining reviews for point of use water heaters, figure out exactly how much hot water you require. For instance, a bathroom sink will need less hot water than a kitchen sink or dishwashing machine.

In addition to reviews of POU water heaters on the web, you can also locate diagrams showcasing the gallons of water per minute typically necessary for a shower, bath, sink, kitchen tap, dishwasher, and laundry machine.

The capacity of a tank-style water heater to supply hot water is dependent on its tank size. Whereas, tankless water heaters depend on the number of gallons they can heat up in one minute.

The whole-house tankless water heaters can produce from 2.5 to 9.5 gallons per minute. Nonetheless, the point-of-use water heaters available in large retail stores and e-commerce websites have a much lower flow rate, around 0.35 or 0.5 gallons per minute. This amount of water may not be sufficient for certain activities.
