Ecosmart ECO 27 Tankless Water Heater Review

In many homes, both old and new, the trends is moving toward tankless water heaters instead of the traditional system.

Not only does the tankless system provide more reliable hot water it also takes up far less space as well. Installation is fairly simple for people with basic maintenance skills and common household tools.

This review will look at the Ecosmart Eco 27 Electric unit and will explain why this is the best tankless water heater for the money.

Working and Performance

One of the most important features of any home appliance, big or small is how well it works.

There is no one who wants to spend good money on something that will fail to meet their expectations in any way.

As a major selling feature of the tankless water heater, unlimited hot water is key.

The Ecosmart 27 Electric model certainly proves itself to be the best tankless water heater even in more severe climates.

In a traditional tank system, water is pumped into the standing tank and then slowly heated to the approximate temperature that is desired. Once the tank is empty it must first refill and then reheat before hot water is available for use.

In the average home, that means that one person can have a shower now and the next person must wait until that process is completed. This can take anywhere from a few minutes to a few hours especially with older, outdated water heaters.

The process with a tankless system is different. Water is heated as it comes in rather than from a tank so there is virtually no limit to how much water can be used. In a unit of this size, there should be enough water for 2 people to take a shower at the same time (in different showers) based on an average outdoor temperature.

The in coming water will be heated and available at an average of three gallons per minute. Colder incoming water and higher demand may slow water flow down slightly.

Heat Output and Flow

Even the best tankless water heater can struggle under certain conditions. For instance if you live in a rural area where water pressure is inconsistent at best or weak, you may not get the peak performance from this unit that you are hoping for.

Other factors that can slow down heat output or water flow can include the location and type of the pipes that you are using and the environment where the unit is going to be used.

Obviously the warmer the water is when it comes into the unit, the faster it will be heated.

This particular unit can be used in areas where the incoming water is as low as 37 degrees and will still boast an outflow of up to three gallons of heated water per minute. The temperature that is desired and the flow of water can be adjusted to some degree as long as there is not an issue with the incoming water or power supply.

Installation and Use

For most people the only difficult part of the installation of this tankless water heater will be removing the old unit. This model is fairly light (weighs less than twenty pounds) and is small enough to be handled without needing a lot of room to move around it and without needing a lot of people to help.

The average homeowner with fundamental repair skills should be able to handle this task in just a few hours of time. You will not need any special tools to install this unit.

Once it is installed in your home the only thing you will have left to do is to set the temperature and that is that. Nearly all of the Ecosmart units feature a digital temperature control which will allow you to set your temperature to within one degree of what you would like it to be. You can adjust this temperature as often as you would like.After you have set the temp you simply use your water as you normally would. There is nothing else to it.

  1. […] you really do not need a Bosch, go for other brands. We highly recommend the Ecosmart ECO 27, Rheem RTE 13, Takagi T​kJr2 and the Stiebel Eltron Tempra […]

  2. […] When you say "best," do you mean the most powerful or the most affordable? […]

    • On our Noritz brand page “best” means the unit we recommend for most shoppers for it’s size, price and quality of all the Noritz units. It my may be the “best” for you depending on what size you need and whether or not you have natural gas, propane or electricity to heat your water.

      Just so you know, we were about to change our our “best” Noritz choice because the one we currently have listed has been discontinued. Our new “best” is Noritz NRC66-DV-NG Natural Gas unit ( This compact unit is a great choice for smaller homes and apartments. At just 6.7 x 13.8 x 23.6 inches and 38 lbs, it can be installed almost anywhere, including attics, garages and closets with proper ventilation. Its lightweight design also means that it can be wall-mounted to save on floor space. In terms of power, the NRC66-DV-NG offers up to 6.6 GPM depending on how many sinks, showers and faucets you have running at the same time.

      While this isn’t the highest flow rate on the market, We’ve found that it’s more than adequate for homes with only 1 or 2 bathrooms.

      You might also like the special low-NOx design that Noritz uses on so many of its products. Like the NRC98 series, these units can be installed indoors thanks to their internal condensing systems. This means increased safety for families especially, and it might be worth the slightly greater price if you’re also given greater peace of mind.

  3. […] EcoSmart is a brand that I never hesitate to recommend to my customers, so you should know right off the bat that this is a good manufacturer with products you can depend on. What I really enjoy about Ecosmart, however, can be summed up in a single model: the ECO 27. […]
