## Description

NG Tankless Water Heater

Review: Works great. Meets my needs and actually reduced the gas bill from my prior 40gal standard tank.
Review: When we first received the unit we put it up and it had a small leak. When turning the knob where it was leaking it was broken and that is why the leak. I called the company and the person that answered the phone was very laksadaisy and said I would get a part. I sent pictures in an email on what I needed but they claimed they didn’t get. They didn’t ask for my address I had to ask them if they wanted it. I was totally unsure if I was going to get the part. About a week went by and I never received an email with tracking so I called again. Then I was told a different story wanted more info etc. then I never heard from them again so I called desertcart to return item which i didn’t want to do because of pipes etc we would have to re do plumbing for a new one. But since I didn’t have hot water I ordered another different one because I couldn’t get the same one. We took this one down and packaged back up. The day the new heater came I also received the part I needed to fix this one. No notifications nothing just the part showed up. So I unpacked it and had it put back up replaced the part and sent the other back. It worked great for what we need. It is actually I. Our garage we were redoing our bathroom so we made a makeshift shower in garage. Now it will just be used for sink in garage.

## Features

- PERFORMANCE The tankless water heater on demand features a heating output of 80,000 BTU and a hot water flow rate of 3.6 gallons per minute (GPM). It can provide continuous hot water for 2-3 water supply points, so it is enough to meet the hot water needs of bathroom, kitchen and home bar.
- NO WAITING REQUIRED Unlike conventional tank water heaters, tankless water heaters eliminate the need for a preheating time of 30 minutes, giving you unlimited hot water on demand.
- Offers 4 modes: plate mode (90 °F), fruit mode (90 °F), age mode (90 °F) and child mode (100 °F). More convenient to use.
- SAVE MONEY The kit already includes the exhaust pipe, so you don't have to spend extra money to buy it separately. With an oxygen-free copper water tank, reduce heat loss and reduce energy consumption. Applied with standard 1/2 inch NPT water connection and gas inlet.
- RECOMMENDATION We strongly recommend that all installations of the unit comply with local building and plumbing regulations at the installation site and must be performed by licensed professionals. (Not recommended for areas over 2 feet)
