9 Best EcoSmart Tankless Water Heater Reviews and Buying Guide
Having a proper heater in your home is always an advantage. Such was for me when I tried to use the EcoSmart hot water heaters available. I’ll be honest, ever since I have tried out an EcoSmart water heater as my friend suggested, I was much obsessed with the brand.
Being a popular brand from all over the world, it is obvious that EcoSmart has numerous products available on the market today. So choosing the best one out of them is always a difficult task in hand.
But after coming up with hours of research and going through all the products, I have come up with a list of the Top 9 EcoSmart Tankless Water Heater Reviews available in the market today. To know more about the buying guide and the products, you can follow this review more.
If you are still confused and do not know which one to choose from the top 9 models available, don’t worry. Yes! I have compiled a buying guide of factors to consider before buying an Eco tankless water heater. Going through these factors will help you make a good decision.
1. Purpose
First thing first, you need to decide how many showers and sinks you will be running. Getting the purpose clear is the most important factor before purchasing a tankless water heater. If you have a bigger house, I suggest you opt for the bigger models. And in case, if you stay in a smaller one, I would suggest you choose the EcoSmart ECO 11 Tankless Water Heater. And if you are thinking of using the heater in your office to run a sink, I would suggest you choose EcoSmart POU 6 Tankless Water Heater as they are small enough to fit your office sink.
2. Water Flow Rate
A major factor that you should look in a tankless water heater before you buy is the water flow rate. Knowing the water flow rate will help you understand whether it will satisfy your needs or not. Moreover, the higher the flow rate is the more sinks and showers you can run on it.
As per my knowledge, I think we normally need a minimum of 2 GPM for a shower and 1 GPM for the sink. In the ECO range, you will find several flow rates starting from 1.5 gallons per minute to 6 gallons per minute.
3. Temperature Rise
The rise in temperature depends on the water’s inlet temperature and can affect the device’s GPM. For example, an Eco 8 can give you 1.5 GPM water to 105 degrees F from 67 degrees F. But in case, the temperature of the inlet is colder, the graph of GPM will go down drastically.
4. Temperature Control
The Eco water heaters come with digital temperature control that allows you to set the temperature as per your needs. But, in the POU models, the flow of the temperature is controlled as it depends on the flow rate. If you have bigger homes, you may want controlled temperatures and I suggest you opt for any Eco model.
5. Location
Another factor that usually a consumer must look at while buying a tankless water heater is the location. Yes! I suggest you consider your location where you want to place the product since the inlet temperature depends highly on the location.
Usually, models that can run 4 sinks and a shower in hot temperature can run only 1 shower and 1 sink in cold temperature. Thus, I would suggest you buy the higher model or you can install individual POU heaters.
6. Energy Rating And Efficiency
Now that you have a plan to buy a tankless water heater, chances are that you want to save on energy. EcoSmart water heaters come in a wide range of energy ratings starting from 8 kW to 36 kW.
But, I would suggest you opt for a model that has self-modulating technology. It delivers only the required amount of energy to increase efficiency to 0.9. As a result, it saves energy and cut back on the electricity bills.
- The product is highly durable
- The product is easy to use
- Manufactured in China
- Amperage (amps): 75. Activation flow: 0. 3 GPM. Flow Rate @ 35 F Rise (gallons/min): 3. 51 gal (US)/min
- The product works and is compatible with 2 X 40 AMP (DP) breakers and 2 X 8 AWG wire
Why Should You Use an EcoSmart Tankless Hot Water Heater?
Now after reading the factors and go in through the products, you might wonder why to buy an EcoSmart water heater only and why not any regular one. Well! Let me tell you the benefits then:
1. Space Saving
The tankless water heaters mean no tanks at all and thus, it allows you to install it anywhere you want. Even the largest model of EcoSmart water heater has a dimension of only 17 x 19 x 3.8 inches. In fact, the POU models are way smaller than the rest. As a result, you can fit them under the sinks.
2. Continuous Water Supply
Another distinct benefit of having a tankless water heater is that it gives you a continuous water supply. There is no requirement to wait for the water to get heated and nor you have to look out for when all the hot water runs out. Having this will let you get hot water whenever you require resulting in 99.98% thermal efficiency.
3. Saves Energy
All of these water heaters are usually tankless and thus the process of heating the water takes place when the water passes through it. On the other hand, the heater with a tank requires much more energy to heat the water.
Moreover, I found that most of these eco series come with self-modulating technology to adjust the power as per your needs. This further saves around 50% of the total cost.
4. Warranty
I found that almost all the EcoSmart water heaters have 12 years of warranty on the heater exchanger. But the lifetime warranty on heating elements, electric water heaters in the Eco series attracts me the most.
On the other hand, I found that you will get a year warranty in the POU series. Eco and gas models come with 5 years of warranty in the general parts and 1-year labour warranty.
5. Safe And Reliable
When you think of buying a water heater, one thing that should come to your mind before investing is reliability. Well! Let me tell you that all the EcoSmart hot water heaters are great at saving energy. And to my amazement, some of the best heaters further reduce the footprint of carbon.
This is because of no combustion products on gas models are found. They are smaller than the usual tank heater as a result when they break, minimum waste goes into the landfills. Moreover, most of the components are replaceable.
The tankless water heaters usually last longer than the ones with the tank, around 20 years. And they come with a lifetime warranty.
But the best thing according to me is that there is no headache of tank leakage, corrosion or rupture, no anode rod issues, and neither any rotten egg smell. Thus, you can go for any product mentioned above as all are safe and reliable.
6. Customer Service
I was researching Eco water heaters and found that most of the consumers report getting amazing customer care support. And when I got my hands on them, I found they were telling the truth. Although, I have rarely faced issues with the products, whenever I had, the customer care people were always ready to solve my queries.
7. Installation
Usually, it is easy to install an electric tankless water heater and one can do it on their own. However, I would suggest you get the help of an expert to maintain the EcoSmart warranty.
So you will not have any headache in case the installation is not done properly or if any case of manufacturing defects occur, you have the warranty to show the company.
However, the process of tankless water heater installation by the expert is quite fast and it will assure you that your heater is set up correctly.
