Questions & Answers

can this be used to warm a 10,000 gallon above ground pool?

Asked by craig September 12, 2020
1
Answer

Good day Craig and thank you for your question. The ECO 36 tankless water heater is a residential unit that can only be used for the house and not a pool, because of it's power modulation. For the size of your pool you can use the SMART POOL 18 which can handle up to 11,000 gallons or if you wanted more capacity, you can go with the SMART POOL 27 which can handle up to 15,000 gallons. If you have any other questions or have any concerns, please feel free to contact our customer support at 877-474-6473. Thank you for your time.

Good day DD. Sorry to hear that you are having trouble with your ECO 11 tankless electric water heater. The first thing that should be done is to check voltage at the breaker and at the water heater. If there is power on in both the breaker and the at the water heater, then the next step will be to contact Ecosmart customer support at 877-474-6473. Most likely the control board has failed due to the power outage. Thank you for your time.

Is there a filter that can be used with this the EcoSmart water heater?

Asked by Vivis August 20, 2020
3
Answers

Good day Vivis. Thank you for your question. Our electrical tankless water heaters do not come with a filter so one will be highly recommended if you live in an area with hard water. In order to determine which inline water filter you will need, you will need to know the hardness or grain of water in your area. Once you know the hardness or grain of water in your area, you will be able to purchase the adequate inline water filter. You will need an inline water filter that descales and helps out with minerals. It is also highly recommended to flush or perform maintenance to the tankless water heater at-least once every 4 to 6 months if you have hard water. If you have any questions or concerns, please contact our customer support at 877-474-6473. Thank you for your time.

Leaks at the element tank.

Careful, mine started leaking and instead of repairing it they say "Oh , you have to disassemble the unit, pull out the elements and soak them in vinegar and replace the o-rings - annually"! And by the way, the manual that comes with it fails to mention that. So go pay a plumber to do all this for you.. They do not stand behind their product.

This is my second one in less than two years. Word to the wise: BE SURE TO SEND THE REGISTRATION CARD IN, otherwise there is NO warranty of any kind. Hoping the second one lasts longer.

Burst after 10 months
Quality :

This was my sixth unit and it too failed within one year of installation. We’ve gone through six of them due to failures and having to keep with the same model for replacements. Previous replacements had issues with the heating elements or temp sensors going out but this time the heating element separated from its threaded cap. We woke up to find 2 inches of water in our bathroom and closet, along with drywall damage because the heater was located in the attic. After thousands of dollars worth of damage, it wasn’t worth it to exchange this unit for another one of its kind. I instead purchased a Rheem heater, and to my dismay it is identical internally, down to the same exact part numbers. Eco-smart warranty is nonexistent, so don’t plan on the manufacture helping you out. If you have already purchased this unit, it is in your best interest to establish some sort of extended warranty or home appliance warranty, this unit will fail it’s just a matter of when. I would also recommend installing an aluminum drain pan designed for tankless heaters, you can order from Home Depot for about $60.

The best feature of this water heater is the temp control. It is great to take a shower and not have the water go cold on you. The only issue is that it does not have the electrical cable and you do need to open and install the electrical connection. The installation instructions are not clear on how to connect electrical cable. If you do not know how to connect 250VAC and ground, may be in trouble. ,

ECO 18 Consistent failures within the last 10 years
Quality :
1
Value :
1
After having the ECO 18, I’ve had consistent failures about every 3 years with minimum usage. The unit is installed inside of a 3/3 townhome with 2 occupants. Lately, it stopped working again, meaning no hot water! This is the third time. To me, it’s too many compared to the conventional and others in the same category. Originally I’ve chosen Eco Smart due to the positive reviews and indication of high quality internal components; however, if the info were true,I should not be having so many failures so often. I also know a coworker with the same model whom also had a failure few months ago inside of their home. This make and product is NOT recommended.
