EcoSmart Eco 27 Tankless Water Heater Reviews

One thing you have to be aware of EcoSmart Eco 27 tankless water heater is that it’s an electric model. What we’re trying to say actually is that if you need a water heater that can be used with multiple faucets simultaneously, you might want to skip this one off. Although the company claims that it’s a “whole home” model, it’s really a tough work for the electric Eco 27 to generate acceptable flow rate when all faucets are turned on. As a positive note, though, electric water heater like this one is reasonably priced. You will hardly need to break your bank just to install a unit of this. You’re going to learn more about EcoSmart Eco 27 tankless water heater throughout this article.

EcoSmart Eco 27 Tankless Water Heater Features

EcoSmart Eco 27 Tankless Water Heater– Lifetime warranty for the whole parts of the unit
– Control knob paired with a nice LCD display to accurately control and monitor the water temperature
– Heating water with a rate of 3 GPM (gallons per minute)
– Electric operation
– Compact unit with straightforward installation


It is a no brainer that the lifetime warranty offered by EcoSmart for this particular model is the most attractive benefit. After all, the majority of HVAC system manufacturers commonly provide 12-year warranty at max. Still, you have to know that this warranty is only intended for the first user. If you buy the unit as a second-hand product and still wish to keep the warranty, you’re obliged to pay a certain amount of transfer fee ($350 for EcoSmart Eco 27 Tankless) and send the necessary information to the company via Certified Mail before seven days of the sale Closing Date. The hassle aside, lifetime warranty still looks very much interesting.

As an electric water heater, the rate of 3 GPM sounds pretty decent but don’t expect that it can provide you with piping hot water. Also, don’t expect that you can run a couple of showers at the same time because with the aforementioned rate, this heater even has to struggle to supply one shower. The water temperature after heating is still acceptably hot, though. So, we think it’s easily forgiven. Like many electric heaters, EcoSmart Eco 27 Tankless still has the tendency to make “cold water sandwich”. You will find cold water flowing out of your facet in the first few minutes but after that, only hot water comes out. Installation is not as complex and frustrating as tank-type model and the installation manuals can’t be any clearer. That said, you will still need pretty decent plumbing and electrical skills.


Similar to other electric models, EcoSmart Eco 27 Tankless is too “weak” to supply the entire faucets in the house with hot water. Thus, you can forget about using it as a whole-house heater. Moreover, it is not approved by Energy Star but then again, most electric heaters also don’t have the necessary efficiency to qualify for Energy Star labeling. Last but not least, expect to shell out extra cost of $250-$300 for some electrical and plumbing components; otherwise, your installation won’t work.


As an electric water heater, this one has its limitation. You can’t compare it to the gas models. All in all, we’d like to say that the benefits that EcoSmart Eco 27 Tankless comes with are more than enough to cover its shortcoming.
