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 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 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 5.0 out of 5.0 by Never ending hot water for large family We are restoring a large victorian home in a rural area. There aren't many plumbers that wanted to work with us due to a tankless system, as many did not have experience with installation. Our plumber had installed one before ours. He had our tankless system installed in about three hours with one trip to pick up plumbing parts he was out of to have it up and running. There is no more waiting for hot water at our house. I can run the dishwasher, two baths and washing machine at the same time, without fear of low water pressure and lack of hot water. We have five children and three of them are in every sport known to man. That means tons of showers every day. Excellent product. I'll never own a hot water tank again. April 30, 2013
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
