EcoSmart Eco 27 Review – Everything You Need To Know

Most of us want a tankless water heater to save some bucks on the electricity bills. These water heaters only “snuffle” electricity if compared to the tank models that cost a fortune to run. So you end up saving a lot on electricity bills. However, that is not the only rationale for getting a tankless water heater.

You would want a hot shower even after doing your laundry or a family member taking one. Now, with a tank water heater providing a mere hot water supply of 30 to 50 gallons, you would be in for a shock. However, a tankless water heater will provide you an endless stream of hot water on demand. 

While a tankless water heater will suffice your hot water needs, a faulty one will do more harm than good. The tankless water heater in focus is one of the bestselling ones, EcoSmart Eco 27 from a formidable manufacturer. This one, thanks to its sturdy stainless-steel and copper components, is bound to last forever and save you money down the road.  

But does the EcoSmart Eco 27 cut as a reliable tankless water heater? Find out in this detailed review.

These are the notable features of the EcoSmart Eco 27.

– Impressive and Instant Hot Water Flow

EcoSmart has an extensive range of tankless water heaters, and in terms of gallons per minute, the Eco 27 stands out. The EcoSmart Eco 27 is capable of providing a whopping 6.5 gallons per minute of hot water instantly, in a warmer climate. Thus, EcoSmart Eco 27 can run a sink and four showers simultaneously. For the price of it, this is the best number of gallons per minute of hot water that you can get. Impressive!  

Moreover, the tankless heater, owing to its aptness, can work effectively as a central water heating system. For the water temperature as low as 45 degrees Fahrenheit, the tankless water heater works fine. However, you can expect the gallons per minute supply to drop to 2.7 GPM below 37 degrees Fahrenheit. Nonetheless, even in colder regions, it is capable of running two hot showers at the same time. 

– Patented Self-modulating Technology and Low Activation Rate

EcoSmart likes to brag about its patented self-modulating technology. The top tankless water heater models of the manufacturer possess this feature, and the EcoSmart Eco 27 is no exception. Are you scratching your head wondering what it does? Well, in simple words, it saves you from paying hefty bills.

What the technology does is that it regulates the working of the heater based on the hot water demand and the temperature. The water heater ignites when the flow is 0.3 gallons per minute. However, it does not waste any time in turning itself off, and thus, it saves you an ample amount of electricity.

So, if there is blazing hot weather outside, the EcoSmart Eco 27 will hibernate and save you the running cost. Conversely, if it is freezing, then the tankless water heater will only heat the amount of water that you need. Therefore, regardless of the weather conditions, the water heater costs little to run.  

– Highly energy-efficient

The EcoSmart water heaters have a knack of running efficiently, running more while costing less. While the smaller models can offer an up to a 60 percent reduction in energy costs, the Eco 27, per the manufacturer claims, offers up to a reasonable 50 percent saving in electricity bills. 

Although the climate and temperature of the water supply determine the performance of tankless water heaters, the EcoSmartEco 27 boasts an efficiency of 99.8 percent at around 45 degrees Fahrenheit. Thus, you get lower bills at the end of the month, and you spend less on maintenance.  

– Easy-to-use and Safe Digital Temperature Control

EcoSmart makes controlling the temperature straightforward and breezy. It doesn’t contain a traditional dial that increases or decreases in multiples of fives. After all, even a single degree makes a difference. So, the EcoSmart Eco 27 comes with a digital control panel to set the right temperature. 

Well, even if you’re not tech-savvy, the device is easy to handle. You can easily set the desired temperature. You can instantly raise the temperature to 105 degrees Fahrenheit. The system maintains the temperature so that the shower is safe. Therefore, you don’t have to worry about the kids burning themselves. 

– Lifetime Warranty 

If the features of EcoSmart Eco 27 didn’t impress you already, the manufacturer gives you a lifetime warranty on the electronic components of the water heater.

However, the warranty coverage comes with a condition. You have to get a professional to install the unit. But it is still satisfying to have a lifetime warranty.

So, if you need an endless amount of on-demand hot water in winters, it will do the job and save you from paying a hefty electricity bill. You can thank the self-modulating technology for this. 

For a climate of 45 degrees Fahrenheit, the EcoSmart Eco 27 is an ideal choice providing up to 105 degrees Fahrenheit at 6.5 gallons per minute. However, the flow rate drops when the temperatures get cooler. Nonetheless, even in colder regions, you can expect the water heater to run two showers at the same time.
