    • A great money saver.
Set name: 7.9GPM|Natural Gas|Ind
I installed this for my customer who had a tight budget. It has been working flawlessly for about 2 months now. Installation was easy and water temp/flow is working as it's supposed to.

Set name: 5.1GPM|Propane|Out
Works and upgrades the house. It was difficult finding a contractor who could put it in. But it works. Sometimes it takes a minute or two to get hot but when it does it’s really hot :) also has a cool remote to set the heating

The product came in a couple of days early! Which was much needed. It’s working like a dream. Installation was fairly easy that we were able to do it by ourselves.

    • Great waterheater
Set name: 8.1GPM|Natural Gas|Out
This thing is terrific. I set the water temperature at 116 degrees and don't need to turn on the cold water anymore unless I need just cold water. No more having to mix hot and cold to get the right temperature.

    • Do not recommend to buy this an APOLLO Performance/ Westinghouse tankless
Set name: 7.9GPM|Natural Gas|Ind
Review Image by Darlene
we recently had an APOLLO Performance / Westinghouse tankless water heater installed. The unit is plugged into power, but the front display never turns on (screen completely dark), so it won’t respond to controls or pair with the app. We tested multiple working outlets and confirmed the heater still has no display or power indication. This appears to be a dead control board or internal power issue. Very disappointing, we have to wait to order the new one to delivery in a week, now there is no hot water in the house. ... show more

    • A great unit
Set name: 5.1GPM|Propane|Out
I'm very happy with the unit. Easy installation and solid construction. A great warranty (I hope I don't use it). A DIY advise, do your homework and download the installation manual. It will help you to buy what the manual suggest you should have. Thank you W.
