1. EcoSmart ECO 18 Electric Tankless Water Heater

Best EcoSmart Tankless Water HeatersThe EcoSmart ECO 18 gives consumers a sizeable draw of hot water that will supply about 2.5 GPM on its flow rate. This should be adequate for a large apartment or townhome, or even possibly a small home with moderate water needs.

In warmer climates, the water does not need to be heated as much, and it should be able to heat water for two showers and two sinks.

By its name, the ECO 18 does pull 18 kilowatts for its power needs, draws 75 amps, and requires two 40 double-poles for installation. EcoSmart’s sizing offering is based on a 240 volt electrical service. Be sure to check your existing electrical panel to ensure you have adequate electrical draw space for the ECO 18.

With a 50 percent savings in water heater costs, the ECO 18 should help you reduce your electric water heating needs fairly quickly. This unit will also save a sizable amount of space in the utility area, coming in at 17″ high x 14″ wide x 3.75″ deep. Especially if you’re removing an existing tank, it would be nice to have that extra space for storage or ease of access to other utilities in your basement or utility closet.

An electric hot water heater from EcoSmart will also give you one of the most extensive product warranties on the market.
