What is a Point of Use Tankless Water Heater? 

Point of use tankless water heater is usually installed near the points where hot water is required. This helps to reduce heat loss and installation cost. If you do not need hot water in multiple points in the home, a dedicated point of use water heater is a good alternative.

It is called the point of use system because heating takes place very near the faucet where the water is needed. They serve single points and are less expensive compared to whole house unit.

Advantages of a Point of use tankless Water Heater 

These are some of the significant benefits why you should consider a point of use tankless water heater

  1. High Water temperature and pressure 

Houses that use old water heater system could have the issue of reduced demand. With a point of use water heater system, the heater is placed right where the hot water is required. This gives water at the required temperature and pressure besides, and hot water flows faster with a reduced tendency of wastage.

Points of use tankless heater especially are fixed out of sight such as under the kitchen cabinet or beside the washing machine. This is a significant advantage of point of use tankless water heater.

  1. They are Cheap

Disadvantages of a point of use tankless Water Heater 

  1. Constant Maintenance Needed 

While the point of use tankless water heater is guaranteed to last many years to come, it is, however, possible under the right maintenance structure. Besides, for the warranty to be valid, the maintenance needs to be done regularly by a specialist.

  1. Making Up for Initial Investment Could take years

Compared to the traditional heater, point of use tankless water heater does cost. However, you get to see this saving in the month to month reduction on energy bills. It will, however, take a while to make up for the initial investment cost.

  1. Not Suitable for Large Demand of Hot Water

Since the point of use tankless water heater is dedicated towards a single point, the amount of hot water gotten might be limited. Besides, it might not be capable of supplying continuous hot water for heavy use.

How much does it cost for a point of use water heater installation? 

The cost of installation of a point of use tankless water heater is usually an essential factor. You could have a professional bill you per hour at the range of $200 to $500, while a plumber could bill you at $45-$150 per hour.

The overall cost involved in installing a point of use tankless water heater is a factor of the various accessories. Besides, it also depends on the type of point of use tankless water heater you are going for: electric type, natural gas or liquid propane as the gas-powered type does require venting accessories for installation.

Different Types of point of use Tankless Water heater Based on Fuel Type 

A point of use tankless water heater can be classified based on the type of fuel. Hence, you can either decide to go for a propane powered type, natural gas-powered or electric type.

  1. Natural Gas Powered tankless Water Heater

These units are powered by natural gas and uses a complex vent system for the air flow and exhaust system. They are usually costly but deliver much power compared to the electric unit.

  1. Electric Tankless Water Heater

They are smaller and easy to install. They do not require combustion since they are powered by electricity. They are pretty efficient and straightforward in installation with the tendency to last very long.

  1. Liquid Propane Tankless heater

Point of use tankless water heater that uses liquid propane is the right choice if you need water at high temperature. It is powered by liquid propane and requires ventilation, just like the natural gas counterpart.

How to Select the Best Point of Use Tankless Water Heater 

The two most important factors to help you chose a reliable brand of tankless water heater are the temperature rise and flow rate.

  1. Flow rate

Measured in gallons per minute (GPM) the flow rate is the amount of water your point of use tankless water heater can heat at a given time. Check out this guide to help you select the right size. Higher GPM values mean the unit can deliver more hot water per minute. However, most units fall in the range of 0.5 to 2.25 GPM. However, you need to get the flow rate value right because it determines the satisfaction you will have from your unit.

We have the following reference points for flow rates of different points

Fixtures Average Flow (GPM) Average temperature (Faharient)
Tub 4.0 102
Shower 2.5 – 3.0 104
Washing machine 2.0 120
Dishwasher 1.5 110
Kitchen Sink 1.5 110

 

 

Hence, a point of use hot water system that will serve your dishwasher and kitchen sink should be able to deliver 3.0 GPM comfortably. You, however, will hardly be using both units at the same time.

Also, if you aim to have a small point of use tankless water heater to supplement the primary water heating system, the flow rate does not have to be too high.

Temperature rise 

The rise in temperature is the temperature of the hot water minus temperature of the incoming cold water. You get this by subtracting the desired temperature at the outlet from the inflow water temperature. For instance, if you want a temperature of 100F for your showerhead and your incoming water temperature is 45F, your point of use tankless water heater should be able to give a temperature rise of 55F.

Bear in mind, however that the higher the temperature rise you have, the more your unit will have to work to accomplish this. In cold climates, for instance, you should take into account the variation in the weather before making a selection. For example, during the winter, your unit could be required to raise your water temperature by 50F and deliver at 0.40 GPM. In the summer, on the other hand, the temperature rise needed might not be more than 30F which will give a 1.60F.

In sizing a tankless water heater, the temperature and flow rate value is essential. This will help you get the right unit that will meet your needs.

Conclusion

If you need a tankless water heater dedicated to a specific point in the house such as kitchen or shower, be sure to check out this review.

An investment in one of the best point of use tankless water heater discussed above is an excellent choice.

This will solve your hot water issue without any buyer remorse.
