How to Choose?

What is its Inlet Temperature Rating?

The inlet temperature rating refers to the temperature that the unit can work with based on the temperature of the supply coming out of the ground. The temperature will vary significantly based on your region as well as the temperature outside. Many of this company’s products will work with an inlet temperature of below 40 degrees Fahrenheit.

One reason why this rating is so important is because it applies to the unit’s overall flow rating. For example, the ECO 27 has a maximum flow rating of more than 6.6 gallons of h20 per minute at a 77 degree inlet temperature, but when the ground temperature drops below 40 degrees, its flow rating will drop below three gallons per minute. Other units like the POU 3.5 will provide less than one gallon of hot water each minute at a lower or higher ground temperature.

EcoSmart provides shoppers with a detailed map that shows the temperatures found in different regions of the United States. You can use this map and the chart provided to find out which tankless heater will work well in your home.

How Many Rooms Will it Supply?

If you have a smaller home with just one bathroom and a kitchen, you can select almost any of the models that the company makes, but if you have a larger home with multiple bathrooms, you’ll need one designed for the whole home. ECO tankless heater are generally the top choices for those who need to supply more than one room with hot water. This includes any half bathrooms that your might have that only have a toilet and a small sink with no tub or shower.

EcoSmart makes both point of use and whole home units. A whole home unit like the ECO 36 provides a more steady and constant stream of hot water and can supply two or more rooms with that water simultaneously. You’ll find that two or more people can shower around the same time without running out of supply too.

Point of use tankless heaters are much smaller in size and designed for working with just one application. The POU 3.5 is a great example of a point of use tankless heater. This unit mounts underneath your sink and has connections that supply the sink with hot water, but you cannot use this model to heat h20 in any other area of your home.

Where are the Fittings and Connections?

You should definitely take a look at all the fittings and connections found on each model because not all will work in all homes. If you purchase the wrong one, your installation costs will rise because the installer will need to rearrange your home and install new wiring and products. The installer may need to upgrade your circuit breaker or fuse box too.

Most tankless heaters have fittings on either the top or bottom, but some have fittings on the sides. Looking at those connections helps you see which one will fit in your home and work with your existing systems.

Does it Work with a Remote?
