2. POU 3.5

This model of POU 3.5 is very active to provide warm water to the single connection due to its point of use design. You would get hot water at 0.5 GPM. This capacity makes it a good choice for a location that needs less water like a boat or a similar location.

With the groundwater temperature 57 Fahrenheit or below, the performance gets affected. Alternatively, this unit is good for an environment with a medium temperature.

The integrated technology is very advance to cut down energy usage while saving energy. As compared to a typical water heater, the energy saving is 60 percent more.

A very low activation flow of 0.2 GPM is needed to start the device. After activation, the flow sensors start working to modulate the flow. The usage of energy is according to the flow rate that varies from low to high.

POU 3.5 is equipped with a digital screen that allows you to keep an eye on the current temperature. The temperature can be adjusted according to your requirements with a 1-degree increment. The temperature range offered by POU 3.5 is 80 Fahrenheit to 140 Fahrenheit.

The compact and lightweight design makes the installation very easy and quick. The same size allows its fitting below the sink or similar narrow space. As you place this heater near the sink so, you do not need to wait for warm water. Additionally, it cuts down the need for a longer pipe.

You need to manage 100 Amps electrical panel and #AWG wire. Plus, ½ inch plumbing connection is also a strong need for a successful installation.

One year warranty is offered for heat exchangers and other parts. No doubt, the warranty time is too short but manufacturers claim that the quality of this tankless water heater is very good to serve you for a longer time.

They are ideal for people who do not usually consume water for more than one user at a time — such as showering and washing dishes at the same time.

Wireless types are preferred in households that use natural gas to heat water; electrical models may require the expensive development of domestic power.

Conclusion

The company Rheem Manufacturing was founded back in 1920, and hot water heaters were one of the first products.

The company bought the Ruud Manufacturing Company, which built the first self-powered electric water heater.

Today, Rheem water heaters are a well-known brand, and the company is a well-known North American manufacturer in providing complete heating solutions.

Rheem is now a wholly-owned subsidiary of Paloma Industries, the world’s largest electronics manufacturer, based in Japan. if you want to see other tankless water heater brands before purchasing, be sure to check the review page.
