  • Great Investment!
This water heater is great. It took me a a full weekend to install all by myself, but I have almost no previous plumbing experience, and few tools. I was replacing an existing tank-based heater, so you can imagine that I had to do quite a bit of plumbing. This heater comes with the valve assembly, so there's no need to purchase that seperately, even though amazon suggested that the two are often purchased together. (I'm sure they are, since many people don't know it comes with the assembly!) It wasn't a big deal, as I was able to ship the valve assembly back easily enough. I'd just like to prevent other people from having that trouble. At the current Amazon price, combined with a rebate I got from my utility company, I paid less to install this system than one of my co-workers paid to have a tank-based heater replaced by a local plumber. This thing is quiet, works great, and was worth every penny! I was originally concerned that 7.5 gallons per minute might not be enough, but in our house with two bathrooms, a high-efficency dishwasher, and an older front-load washing machine, it seems to be plenty. I keep wanting to try running both showers simultanously, but I haven't done that yet. I think it would work fine. The only downside for this is that it does take about 20-30 seconds longer to get full hot water than our old tank heater did, but in the past three months we've gotten used to that. I had intended to put a small electric tank heater in as well to compensate for this, but the plumbing and placement just didn't seem to want to work out right for that, so the little tank is sitting unused. That 20-30 second delay does translate into a waste of about 5-10 gallons of water per day, which troubles me. I may still decide to install that little tank later on. I've also read about pump systems that let you cycle the water through the pipes for 20 seconds or so prior to using the hot water, which intrugues me, but those systems cost around $400, which seems like a lot of money for what they gain you. In the end, I'm very happy with my purchase. ... show more

  • Working fine so far.
My husband and I installed this ourselves. We went from an electric 50 gallon water heater to this. First, I did a lot of research, looked up the codes in our county and city and made a plan. I bought this tankless water heater in the summer, It took me several months to install as I had to remodel the room it was going into first. The hardest part was cutting a hole through some bricks to make sure the venting would fit everything else was pretty easy. I just ran a gas line and ordered the proper venting. The water lines were pretty much where they needed to be. Once all the lines were in place the heater went up in a day. We have been using the heater for about a month now. The outside temp got down to the teens for a few weeks. I can honestly say I love the heater. I do not have to worry about saving any hot water for my husbands shower because there is a never ending supply. We had people over and they also enjoyed the ability to shower without waiting for the water to heat up. The guest shower is a little farther from the heater and they did say the faucet took a little longer to demonstrate the change in temp. Not sure if that is due to the heater or the faucet. My kitchen is the farthest from the heater and it does take a couple minutes to get hot water to the faucet. I have found that if I rinse the dishes with hot water, then the dishwasher has plenty of hot water. My gas bill did not go up much over the last month (it was a lot colder and the increase could have been from the house heater). I have not gotten an electric bill yet but I bet it will be way less. The heater is not even as loud as my washer or dryer, so I am not sure why others have said it was loud. I will never go back to a tank system. ... show more

  • I LOVE having hot water on demand, lowered my utilities
I researched this unit and I am very happy with the product and how much it has saved on my utilities. I am only heating the water I need immediately, not keeping a tank heated 24/7. Best thing I bought for my home. I have a 1000. sq foot home w basement/ 2 baths.
