## Description

NG tankless water heater

Review: Is good except controller had been used had a scratched up screen
Review: The unit has been received and is as described in the product description. I have given 5 stars right now but it's not hooked up yet so I will have to come back and update my review once we have it up and running. Right now my fingers are crossed that it's exactly we are looking for at the cottage. Hot water is so important especially when you are dealing with cold well water!

## Features

- Performance: The on-demand tankless water heater boasts a heating capacity 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, making it sufficient to meet the hot water needs of a household's bathroom, kitchen, and bar area.
- No Waiting Required: Unlike traditional tank water heaters, tankless water heaters eliminate the need for a 30-minute preheating wait time, allowing you to have unlimited hot water on demand.
- Provides 4 modes: Dish mode(100℉), Fruit mode(95℉), Elderly mode(104℉) and Infant mode(107℉). More convenient for you to use.
- Save Money: The kit already includes the exhaust pipe, so you don't need to spend extra money on purchasing it separately. With an oxygen-free copper water tank, it reduces heat loss and lowers energy consumption. Applied with standard 1/2" NPT water fitting and gas inlet.
- Recommendation: We strongly advise that all installations of the device adhere to local building and plumbing regulations at the installation location, and should be carried out by licensed professionals.(Not recommended for areas over 2,000 feet)

*by K***. on 5 December 2024*

Unit at first wouldn’t work at all. Then after it started working it does not keep up to more than one hot water tap on at a time. Then after 2 months it quit working again. Manual and troubleshooting is a waste.
