Rated 5.0 out of 5.0 by vicksbr80 We were replacing a 50 gal. electric w.h. I have a tankless gas water heater at home and wanted to put one at work. This was perfect for our application. We were able to vent with 3" pvc due to this being an ecosense. We have much more room in that corner as you can see from the picture. Easy to install and will save us tons on electricity since this is natural gas and is demand only. Quality piece of equipment. Works like a champ. January 13, 2015
Rated 5.0 out of 5.0 by So far better then expected Took me and my father(licensed contractor) about 8 hrs to install, along with 2 trips to home depot. about $275 in extra parts needed. Copper, valves, new 3/4" gas line, PVC pipe, ect.. Also spent about $50 in tools. Pipe cutter, Soldering torch, ect... Myself nor my father had ever installed one. But it was pretty straight forward, and the fold out EZ-install directions made it pretty easy. The unit is factory set for 120deg max. You have to installer override at the keypad and you can get it up to 130deg or 140deg :). It only goes in 5-10 degree increments. It takes about 20 seconds longer to get hot water to the far end of the house. About 1 minute total or a little more for the water to get hot. Not a big deal to us. A little wasted water, but we are saving gas :) The whole family loves this thing so far. Hottest showers we have ever had. No rush to get out, no caring if someone already took one, no care if someone is taking one right now. If you have any plumbing experience, and a helping hand. This is really a fun project. Be sure everyone is showered as it could run into 2 days. For that reason it's not a good candidate for and emergency replacement. But as a premeditated Replacement it's a must. Contactors will want to charge $1000-$1200 to install one. As much or more then the unit itself. About $800-$900 in savings if you can do it yourself in a day. Worth paying that handy friend(or dad) to help you out. Total cost $950 Unit $90 Tax $275 parts $50 tools $1375 total. Cost are comparable to installing an 85 gallon tank water heater with a 10-12 year warranty. If you can install your self. Operating costs are aprox half of that 85 gallon. It's sure is nice to know when you go away for a few days the water heater isn't spending your money while you are gone. March 22, 2015
Rated 4.0 out of 5.0 by Works fine, difficult installation. It works fine but it's too soon to judge reliability. Takes less space than a tank. Installation is difficult. 1. Two 3 inch pvc pipes through the wall. 2. Condensate drain into a lavatory drain. 3. Requires high gas flow. Dedicated 1" gas pipe to meter. Gas company installed larger meter. 4. A dedicated electrical circuit. 5. And, of course, the water pipes. 6. And a remote control wire to second floor apartment. November 20, 2012
Rated 5.0 out of 5.0 by Worth every penny!!!! Works Awsome. Hot water all the time anytime!!!!! Having many teenagers. No more short cold water showers or shaves. Only got unlimited hot water when I went on vacation and now I get that effect from home. Two thubs up:) March 24, 2015
Rated 5.0 out of 5.0 by Outstanding product - Superbly engineered This on-demand heater is remarkable, and it provides an endless supply of hot water for my entire house. The efficiency is awesome! The installation instructions were very clear and complete, so it was not a problem to install myself ( however, if you aren't comfortable working with plumbing and gas lines, I would recommend using a professional installer) April 23, 2014
Rated 4.0 out of 5.0 by Good Product Be aware that it could be noisy when the burner is on. It will depend on where it is installed. In my case it was installed on an interior wall and could hear the burner running when the hot water is turned on in the adjacent room. Also, disregard what Home Depot people online or in the store tells you that it will work with 1/2" gas supply line. I was told the heater will work though less efficient. Not true, water heater will go off with error message. I had to run a dedicated 3/4" gas line from the meter for it to work. Be aware this is a condensating water heater....so you will need to collect the condensate or have a place for it to drain. April 14, 2015
Rated 5.0 out of 5.0 by Needed professional instalation, but no problems with instalation. Provides plenty of hot water. I spent a lot of time comparing different tankless water heaters and reading online instructions and specifications before deciding on this model. My plumber helped with advice on features, such as, ability to vent with PVC, plug-in vs. hard wire, placement, capacity, etc. Worth having professional installation, but must factor in the fee. Took plumber about 12 hours to install (reroute water and gas pipes, vent, remove old water heater). February 18, 2014
Rated 5.0 out of 5.0 by Easy install and works Great. 3/4" connectors for Gas and Water. Requires a drain close by. The only thing that was confusing on install was that the spacing between the intake and exhaust were different on the Heater and the outside cap. We have 2 bathrooms and it seems to work excellent. Much cheaper to run over the last month then our electric tank water heater, and never runs out! January 14, 2014
