Buyer Guide

1. Fuel type:

Point of use tankless water heaters is electricity, natural gas, or propane to fuel their operations just like any other tankless water heaters. Fuel has a great impact on the working on a point of use tankless unit. A point of use tankless fueled by electricity cannot give as much output as a point of use fueled by natural gas or propane combustion. Similarly, natural gas point-of-use tankless water heaters are cheaper to operate than an electric tankless water heater.

But it doesn’t mean that you should go for a natural gas point-of-use tankless water heater. The reason is that natural gas-fueled tankless requires additional installation of gas pipelines. Which will boost the cost incurred to a very high level. Hence it will take a long period of time to recover your cost in energy saving.

This is probably the main reason why over 90% of the point of use tankless water heaters are fueled by electricity.

2. Hot Water Flow rate: (GPM)

If you are buying a tankless water heater, one thing that you need to know is the flow rate. Most tankless water heaters work on a flow rate basis which means that they have only a certain capacity to heat water. Once exceeded, running into cold water is the obvious conclusion.

Your point of using a tankless water heater cannot do anything about it. Especially, in the case of point-of-use tankless water heaters which are designed to be smaller and with limited power to support a single outlet. Hence, you cannot blame the POU water heater for running into cold water. Moreover, there is a big impact of incoming water temperature on the tankless hot water capacity. A POU tankless water heater is going to take much longer to heat icy cold water than to heat water that is slightly cold.

Therefore, always look into the actual hot water capacity instead of the labeled hot water capacity of a tankless water heater. You can do so by looking into the specification sheet of the tankless model you want. A specification sheet like this can readily be found on the internet for free. They tell you exactly how much hot water you can get from that specific model based on your incoming water temperature.

3. Total Wattage of Heating Element

If you are buying an electric point-of-use tankless water heater, one trick you can use to evaluate whether it will be able to meet your need or not is checking its heating element Wattage. Most of the point-of-use tankless water heater heating element wattage requirement ranges from 3Kw-15Kw. This wattage also tells about the healing power of the water heater.

Typically, point of use tankless water heater having a wattage of around 10Kw is sufficient to provide instant hot water for a shower. While a wattage around 3-4 Kw may only be able to support the hot water needs of a single sink only.

4. Heat exchanger composition

Heat exchanger or heating element composition plays an important role in the performance of a point of use tankless water heater. A point-of-use tankless water heater that uses copper heating metal is considered to be one of the best options.

As copper has 20 times more heat conductivity than steel or any other metal, it can ensure higher efficiency in transferring of heater to the water. Hence, point of use tankless water heater which already have limited power, boosted by copper part gives better performance. In addition, copper heating elements are also more resistant to corrosion due to sediment buildup.

5. Tank or Tankless type:

Check whether the point of use you are looking for is a tank-type or tankless one. A tank-type point of use and a tankless point of use can be difficult to tell apart most of the time. A point-of-use tank-type water heater can only give you as much hot water as it can store. After that, you’ll have to endure a long wait before receiving even a small amount of hot water. But the benefit is that you can get a continuous stream of hot water through multiple faucets as long as the stored hot water doesn’t end.

While on the other hand, a tankless point-of-use water heater gives you an endless hot water supply although at a limited flow rate. Hence, you don’t need to fear running out of hot water midway, and a tankless water heater also gives higher energy savings.
