Tankless Water Heater Electric ECOTOUCH 9KW 240V on Demand Water Heater Self-Modulating Instant Hot Water Heater Point Of Use Water Heater ECO90 Black - desertcart.com

Review: Simple and Works - I used at my camp. To replace the 10 gallon mobile home electric water heater. My set up is a well pump pumping from a 50 gallon drum, that pumps into the main. I haven't had an issue with air, or flow rate. Only once in the 30 showers taken a error code came up. No error codes in the 1000's of times the sinks were ran. I just reset the power and it worked again. Super simple to use. Power, temp up and down. The water in the drum is around 60 degree's, and the water coming out of faucet on full temp will hurt. Saved money even if I only get a few years out of the unit.
Review: Super cool - We installed this unit to service a double sink vanity in our master bathroom. We have a gas fired, tankless hot water heater but it’s mounted on the opposite side of our house - near my kitchen. My wife and I for years would turn on our shower and come back in several minutes once the hot water finally arrived on the mater bathroom side of the house. This is less of a big deal when compared to the number of times we wash our hands in the sinks - especially in the middle of the night. We were sick and tired of rinsing our hands and brushing our teeth in cold water. This unit is sleek, compact and carries a punch ! It mounts very easily. Its temperature controller is easy, bright and straight forward. The build quality is solid. It takes 10 seconds to start to feel some warm water and in 20 seconds (total) the water is super hot. This is a very cool design. We’re pleased with this unit here in North Carolina. If your’e in the New England area you may need to up-size a little

## Questions & Answers

**Q: Does this unit have to run on 240 volts or can you run it off of 110 volts**
A: Dear valued customer,
Thanks for your great support in ECOTOUCH. We need to clarify that the electric tankless 9kw water heater works off 240V. It will not work if you run off 110v.

What’s more, we remind you that you should run 8AWG/2 with grounding wire to get 240V from the breaker panel and you should get a 40AMP double pole breaker as well.
Any other question, please contact our ECOTOUCH Customers Service: kjsjxsb@outlook.com.
Wish you pleasant Shopping.

### ⭐⭐⭐⭐ False start but great finish
*by D***S on May 7, 2020*

Our need was lack of hot water to kitchen sink since house tankless is far from the kitchen. Concur with comments on expense of installation: Installation required an electrician to install 8 gauge, 40-amp, 240 volt service to the unit, plus a plumber to plumb the unit. For that reason, the actual purchase of the heater unit was the smallest part of the investment. The heater unit is very small and mounted easily in a tight space at the back of the sink cabinet, off the floor, out of the way, and unobtrusive-see photo. When initially connected and turned on, it failed with error code indicating replacement required, emailed service (no phone support)--surprised to get response back within the hour, confirming error and asking for original order number and shipping address. New replacement unit arrived on following Sunday, installed and good to go on Monday. So our experience with service was very good. After 4 months unit is still performing as advertised and we have constant hot water to kitchen sink in less than five seconds. We do have to remember to touch to reset if we have the power cut off but otherwise we finally enjoy hot water in the kitchen.
