      Verified Purchase

      Igniter is faulty. The burner won't stay lit for more than 30-40 seconds. My own fault for not checking out the company before ordering. Discovered numerous bad reviews related to the very same problem. NOT a good buy.

    • DO NOT BUY!

      We bought ours 3 years ago. In the last 6 months we have had error codes E1 and E3 repeatedly. This means ignition failure and dry combustion. There is gas in the lines so something else is wrong. We have called and sent emails. The 2 calls back and a few emails have been no help. They are trying to say we don't have enough pressure coming in. The gas company has been out and everything is fine. For what ever reason they do not want to stand behind their product. It is still under warranty but no one from tech support wants to send anyone out. Now they don't answer or return calls at all. As of today it won't heat past 59 degrees without an error code. We are forced to buy another brand.

    • Heats water well, but quality is not great.
      Verified Purchase

      This product worked great for a few days after I had it installed. I can heat the water to well above the temperature that I want. So I have it turned down to about half power I get 106 F water which is where I like it. But it can go higher easily with one shower one sink going. The only problem with it is the exhaust fan seems to get jammed up. When this thing senses water flowing it has to start an exhaust fan but sometimes the fan won't start and you get an error. I found that if I just give the upper right corner a little bump with my fist the fan will start. This happens roughly every other day. I cant pin down what causes it, temp? humidity? I would return it but it costs money to have it installed again... so I will probably just live with it until I get sick of it and buy a different one. If it wasn't for that I would rate this as 5 star. Great deal for the money.

      Verified Purchase

      this is a good product but must say the directions are not good they directions for dummies because I had to send email and call them to have help to get this thing working correctly but they were very helpful in doing so the manufacture that is I would recommend it to others that don't have room for a large hot water tank and the cost is cheaper than a hot water tank

    • Q:

      "The manua says that the unit must be plumbed using Metal from the water source to the heater My house and most houses In the county are plumbed with CPVC Does it mean that the connections to the unit have to be metal? or does it mean you have to use a metal fitting at the unit then connect that to your existing pipe"

      • A:

        Per the manual it is recommended for the water lines to be metal. This means we recommend for the lines to be metal, not only connections. We are not plumbers though, so if attempting to install in any way other than the manual states, please refer to your plumber for additional info. Thanks - Eccotemp

    • Q:

      "Can it be installed to replace existing water heater without any modification to vent (Basically, tie into existing vent). I was previously told that for such systems, the vent has to be larger than what we normally see with existing gas/electric water heaters."

      • A:

        Hello nadima, Yes from looking at the manual it does look like this can replace a existing water heater. Here is the manual http://www.kotulas.com/wcsstore/KotulaStorefrontAssetStore/images/pdf/25627.pdf Have a great day!

    • Q:

      "Can this unit be converted to propane?"
