Product Overview

The MAREY ECO180 electric tankless water heater was designed with high-quality parts and components, including a patented heating element and a stainless steel cover. The water instantly heats as it pipes through the heater, delivering instant and endless hot water. It is also called water heater on demand, as the heat exchanger turns on using electricity only when the hot water is running. An external digital control panel allows you to easily adjust the water temperature to be set at your desired output temperature, no matter the water flow.

high mineral water

I currently use a 40 gallon electric heater and haven't had problem with buildup on the elements yet. Will I have problems with high alkaline water and high iron content..Is the element replaceable if it fails, and what is the cost of the replacement
Asked by: Ricky
I don't believe you would want to replace the elements in a tankless electric heater. I have seen people just change them out. You will DEFINITELY WANT A WATER SOFTENER ahead of ANY TANKLESS HEATER, PERIOD!

5.0 GPM Electric Tankless Water Heater - 18 kW 220-Volt is rated 3.7 out of 5 by 28.

My water pressure is pretty low to begin with but I still needed to choke down the inlet to get the water up to set temperature. This is for a single bathtub at considerably less than 5 gallons per minute. Not a huge hardship but it was disappointing..

Rated 4 out of 5 by from Good Choice to a standard waterheater The product performs perfectly as described....but. A couple of things could have been better explained in the description and there is a way that it performs better that varies from what people used to tanked water heaters are familiar with. If you are pre-preparing for its arrival you need to know that it IS 100amps, but that it is two double pole 50amp circuit's, so that's four power wires and a ground. And when you're running it don't set the temperature to the maximum or it will cycle through "over heating" a lot. Set it down one notch and it works perfect. And when you run a shower, turn it all the way up for a few seconds and then down to where you normally run it. it will heat up faster that way. Remember this is not a tanked water heater, so there are different rules. Other than that, which I consider part of my learning curve, it is the best decision I've made for home improvement in quite a while.

We installed the tankless hot water heater for our shower a little over a week ago and we are thinking of returning it. Admittedly, we probably underestimated its ability to heat the ground water in our area- but according to the chart - it should be able to handle heating 2.5gpm. We find ourselves adjusting the water pressure up- to make it work harder- then down to get up to temp. And then it often can't maintain the heat and during the shower, the temp will drop a few degrees. The inconsistancy is really a problem and while we may be saving on electricity, we are not saving on water. We often have to run the shower for 5 minutes before you can get a good temperature.

I obtained the electrical guidance from Home Depot's specialists, purchased the needed parts and pieces for the proper electrical connections and installed the unit my self. I has only been a few days and we have had a few glitches but for the most part it is working well, I would prefer to give it a month before making my final recommendations. It certainly has the potential to get five stars from me.

When it took them 2 weeks to call me back. I decided to replace my existing tankless water heater with the same manufacturer I had. Niagara Industries out of Miami Florida.

I return the tankless water heater because after removing junk out of my utility room the leak was coming from a pipe leading to my water heater. Confucius say (if it's not broken don't replace it.) So I'm hanging on to old unit.
