What is a Point of Use (POU) Water Heater?

A POU or point of use water heater is a small-sized electric appliance that is for the purpose of delivering hot water on demand and into a single fixture of your choice. You can either install it for your kitchen sink or for your bathroom faucet.

The greatest advantage that a POU water heater has to offer is that it saves water as well as energy because it eradicates the delay in the delivery of hot water. The delay is associated with water getting hot before reaching your faucet, and it occurs due to the flushing out of the water from the pipes between your water heater and the faucet.

Types of Point of Use Water Heater

There are two types of these POU water heaters; one is tanked, and the other is tankless. Both these types work very well, and they have their own pros and cons. It all comes down to your personal choice as to which one you choose to cater to your needs.

  • Tanked POU Models

The tanked models work very similarly to the whole-house models. These come with a storage tank where the heated water is stored. These models are limited to the per hour amount of water they are capable of heating.

The tanked POU models have different storage sizes ranging from 2.5 gallons to 20 gallons. If you want to use this model for a single fixture where the demand for hot water is low, then a 2.5-gallon capacity will suffice.

  • Tankless POU Models

As these models don’t have any tanks, they don’t store any water. These models only operate on demand. You can measure their performance by GPM or gallons of water per minute that they can provide.  Most of these models come with a capacity of 2.0 – 2.5 GPM.

These models will make sure that you will never run out of hot water and for this reason, they are quite popular. To find the best model to meet your needs, you must find out the number of faucets and fixtures running at the busiest period in the day. This way, you will be able to find the GPM that all your fixtures need.

Bathroom Sink0.5 to 1.5
Kitchen Faucet1.0 to 2.5
Shower1.0 to 2.5
Dishwasher1.0 to 2.5
Clothes Washer1.5 to 3.0
Bathtub2.0 to 4.0

Things to Consider Before Buying

Here are some important elements that you need to consider when buying a point of use water heater.

Flow Rate

This rate is measured in GPM or gallons per minute. It is the amount of water that a unit is capable of heating at any time. This unit is specifically associated with the tankless units, and the higher it is, the better will be your water heater in terms of performance.

Temperature Rise

Another feature that is directly associated with the tankless models, the temperature rise is the number of degrees that a unit requires to increase the water temperature. The thing is temperature rise and flow rate are inversely proportional. This means that if the temperature rise is high, the flow rate is going to below.

Tank Size

Of course, this is the feature that is associated with the tanked models. It determines the amount of water that your water heater can hold. The bigger the tank, the better it is because you won’t run out of hot water quickly depending upon the consumption.

Recovery Rate

This is again a feature of a tanked version of POU water heater. It is the time required to reheat the water inside the tank. Recovery rate will be high for a large tank, but your unit will require high wattage as well.
