EcoSmart Eco 27 Review

A typical tank-style water heater for residential usage is designed to hold about 30 to 50 gallons of water, which is then heated to a pleasantly warm temperature using either gas or electricity. To preserve the water temperature a tank-style water heater for a whole day (periodically) consumes electricity.

When hot water is drawn from the tank (you get a shower, a bath or so), cold water is added so it can be heated again. During periods of high usage, a tank can easily be depleted of hot water. When this happens, you’ll need to wait for the water to heat before it can be used again. In that period of time, your tank-style water heater consumes much more electricity than it is in a standby mode.

On the other hand, a tankless heater uses electricity only when you need warm or hot water. Yes, it needs a lot more power to operate, but that is exclusively in the time you “ask” for hot water. A tankless water heater doesn’t consume any electric power to heat water unless you have an open hot tap.

EcoSmart Eco 27 Features

  • Compact: Because of the unit’s sleek compact design, the EcoSmart Eco27 is capable of fitting into tight spaces.

Eco 27 Tankless Water Heater Performance

The EcoSmart Eco27 is an efficient electric tankless water heater. It has self-modulating technology and a smart energy-saving design. The total wattage of the unit is 27 kW, however, with three 9 kW individual heating chambers inside.

Measuring only 17” x 17” x 3.6” the Eco 27 is easily mounted on the wall, saving you up to 12 cubic feet of space that you could lose by using a standard equivalent tank-style water heater.

The three individual heating chambers allow the tankless unit to use only the energy needed to heat the water you’ll actually use. EcoSmart claims that their water heaters can reduce your water heating costs by up to 50% because of this technology.

Like all tankless water heaters, the GPM (Gallons Per Minute) flow rate is determined by the temperature of the incoming water, or more accurately the “temperature rise”.

EcoSmart is very upfront about the GPM expectations and states in their literature that this unit will deliver 3 GPM when the incoming water temperatures are as low as 37°F. With a 3 GPM flow rate, you can expect the Eco27 to deliver 2 showers simultaneously in most circumstances. Eco27 delivers enough power for small and mid-sized US homes.

Eco27 Warranty

The EcoSmart brand delivers an incredibly limited lifetime warranty on its water heaters. This model Eco27 has a limited lifetime warranty, with thoughts on your mind: the unit must be installed by a licensed plumber/electrician within 30 days of purchase.

Installation

The things you need to know when installing an electric tankless water heater.

Electric tankless water heaters are designed to be installed indoors. Another thing you should know is that these units require a substantial amount of electricity to operate.

Electric tankless water heaters allow for a more flexible installation location. If you have a multi-story home, and you want to install an electric tankless water heater, you can easily install it in the basement due to its bulk. However, you can install this tankless water heater on the second floor where it’ll be nearer the showers and be better able to heat their water.

NOTE: To install an electric tankless water heater, you will need to call in a professional. That way you’ll ensure that your electrical system can handle the following: 27 kilowatts, 13 amps, 3 x 40 amp double-pole breakers, 112.5 amps of maximum power, and an amperage draw of 113 amps. And finaly, like we wrote before, warranty is only valid if you call for proffesionals to install this unit.

Value For Money

The Eco27 is a very reasonably priced electric tankless water heater you can find out there. Due to all the features it delivers, self-modulating technology, initial purchase price, and the lifetime warranty, the ongoing energy savings make this tankless unit hard to beat.

This unit delivers 6.6 gallons of hot water per minute (GPM) at its peak performance. But in most situations, due to the cooler incoming water temperature, you can expect an optimal 3.0 GPM, which is capable of heating 2 showers at the same time.

How to explain a self-modulating technology? Eco 27 comes with patented self-modulating technology, which means that the Eco 27 is capable of regulating the exact amount of energy needed to heat the required hot water. This feature will save you money since nearly all of the energy needed (99.8%) is used in heating the water.

Before you decide on purchasing a tankless water heater: If you’re buying this unit to replace a tank-style water heater, check and make sure that your household has adequate electricity. Electric tankless water heaters pull a tremendous amount of electricity, and older homes will need to be upgraded. If you need to upgrade your electrical supply you’ll undoubtedly add substantially to the initial cost.

Things we like:

  • Space Saving: Uses less space than a tank-style water heater
  • Saves Money and Energy: Since it only works when you need hot water, the Eco 27 won’t draw electricity during standby times
  • Self-Regulates: The Eco 27 can adjust the amount of energy required based on the amount of hot water needed
  • 99.8% Energy Efficiency: This rating means that nearly all of the energy drawn to operate the unit is used to heat water!
  • Energy Savings: You can save up to 50% in energy costs when you switch from a traditional water heater
  • Endless Supply of Hot Water: When your tankless is sized correctly to your home, hot water never stops flowing

Things we don’t like:

  • Fuel Cost: Since electricity is typically more expensive than natural gas, the Eco 27 will cost more to run than a gas tankless water heater. Although electric tankless heaters are more environmentally friendly – so it’s a bit of a trade-off
  • Instant Hot Water: When you open a hot water tap, the Eco27 immediately turns on. However, there will be a delay for the hot water to reach the faucet as it travels through your home’s pumping. This is true with all water heaters, and if having instant hot water is important to you, consider installing a small tankless unit at the source
  • Sizing is Critical: Purchasing the right size tankless is a must if you want to have an endless supply of hot water

Final words

The EcoSmart Eco 27 Tankless Water Heater can be the unit you want in your home. Its advanced technology and compact design deliver unlimited hot water that will also save you money on your energy bills.

If the unit’s capabilities do not quite fit your needs, the manufacturer, EcoSmart, offers a variety of models with a different power ratings.
