    1. Tankless water heater

      These are a great value for a smaller household and well save you about $30.00-$100. a month. I've had one for almost 20 years now ( same one ). I buy these for my friends now. on 23rd Mar 2015

    2. For the price it's amazing

      It's an awesome little water heater, we are using it for a 1200 sf modular home and worked great

      my only complaints are the water release valve at the bottom DON'T touch it, if you do you can never get it to stop leaking, we accidently turned it when we were initially trying to get it to work before we figured out we needed to put D batteries in it.

      Had to have plumber fix it.
      Also the connections are not standard size so be prepared to pay about $200 more. I actually went to the store and bought all the conversions myself and paid $214!

      You also have to have consistent water pressure or it stops working. sometimes out water pressure gets low and it doesn't register the water coming thru.

      Once you get kinks worked out. It heats instantly and it's awesome.

    3. Follow the directions and it works like a charm

      OK - first off I bought this unit because of the simple electronic start (with just 2 size D batteries). Also the attractive price. I read all the reviews and REGISTERED the warranty the day after I got it.
      I read the instructions, then re-read them and watched the installation video a couple of times.
      The biggest setback was the 4" vent pipe that was needed. My old water heater had a 3" vent pipe.
      I hooked up the water and gas lines myself and had help with the vent pipe because of the sheer awkwardness of it. I vented mine through the roof.
      The 1/2" gas line just wouldn't twist onto the gas orifice on the water heater, don't know why but the gas line female end was too small. I got a female / female connector at the hardware store and it worked just fine.
      It took a couple of days to dial in the right settings for my needs. I AM SO GLAD I GOT THE DIGITAL PANEL model. Took a lot of the guess work out of the temperature and only costs a little more.
      I never run two hot water sources at the same time, if I did, I assume I would have to tweak the settings again.
      I love the fact that I'm not wasting energy heating water all the time in a 40 gallon tank.
      By the way - I am a 61 year old woman.

    4. Great little appliance

      The water gets hot and we have not had any issues other than the pressure valve being made of plastic and leaking but I believe we fixed it.
      The install took almost $400 dollars because the fittings were completely different sizes then the plumber has ever seen on a water heater and we had to buy all the parts

    5. Happy So Far

      It works like it said it would. I'm pretty happy with it. I needed something for a real small space to take the place of a full size water heater and it works good. The flow rate is less than I expected, but the temperature is good. I read about a lot of different models and a lot of reviews before I bought it and so far I haven't had any problems on 10th Oct 2013

    6. So far, so good

      Overall it's doing what I want it to do, although the flow and temperature to the back of the house is a bit less than in the kitchen. Still, it's fine for my needs--I am just waiting for the gas bill to see if the savings are as advertized. on 17th Sep 2013

    7. is ok

      look good. ask me again in 2 year on 1st Aug 2013

    8. Thanks

      Fast shipping, Good condition, i'm happy. Thank's on 22nd Jul 2013

    9. No hassle exchange

      Thank you! Replacement exchanged w/o problem. UPS was the problem. on 22nd Jul 2013
