EcoSmart ECO 18 Electric Tankless Water Heater

The EcoSmart ECO 18 gives consumers a sizeable draw of hot water with a flow rate of about 2.5 GPM. This should be adequate for a large apartment or townhome, or even a small home with moderate water needs. If you are in a colder climate, the ECO 18 can power one shower and one sink at the same time. In warmer climates, the water does not need to be heated as much, so it should be able to heat water for two showers and two sinks simultaneously.

True to 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 size 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% saving on 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 x 14 x 3.75 inches (HxWxD, respectively). Especially if you’re removing an existing tank, that extra space will come in handy 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. If you’re new to tankless water heaters, a reputable manufacturer may be important to you. Customers are very happy with the customer service support from the team at EcoSmart—technicians are readily available to help with sizing, installation, and maintenance questions.

Next, you’ll need three 40-amp double poles available inside for the hard wiring of the ECO 27. This EcoSmart ECO 27 has a max draw of 27 kilowatts at 240 volts, so it will use quite a bit of electricity when it is in use.
