Easy hook up, for replacement water heater on my house

Installed this to transition my water heating to gas for economy. This unit hung on the basement wall and didn't require an enclosure except for some sheet metal to encase the feed pipes. Original heater was left in place and valved off as a backup. This unit produces a nice flow of hot water that continues until you shut the water off. It takes a bit longer to heat up due to the gas startup and the added 12' of piping which is to be expected, but it is only about 5 to 10 seconds depending on which faucet is being used. It only runs when the water is turned on, so no tank heating is required. I think it is going to save me a noticeable amount on my electric bill even after the gas bill hits.

My old one was broken and instead hire someone to install a new one and paying 5000 dollars, I decided to do it by myself! It works very well.

Had to return after installing it since it didn’t work. Ignition didn’t work. Do not recommend.

We bought this for a customer and installed. They were very happy with the water heater. We did have a little trouble finding the correct cover for the pipes because that doesn’t come with it, but we eventually found it and the customer was very satisfied with the water heater.
