I was and am still using my 4 gal under sink Bosh unit but 4 gal wasn't enough. Put this 12 gal baby right behind sink in another room and piped it all through both water heaters and now have 16 gal instant hot water. Would highly recommend this water heater. Just hope it lasts.

The water heater does what it is supposed to do. I had never installed a water heater before but it was relatively easy for what most pay people to do. The ignition electrodes had fallen off in shipping so it was frustrating to find it didn't work for a few minutes. I eventually got it all sorted. My only gripe with the unit itself is that the water fluctuates temperature when it powers down while still providing hot water. I will probably figure it out, but the water heater does it's job otherwise. I have tested it with two showers, dishwasher and clothes washer going at the same time. I chose this model for the price mostly, so it's what I expected. If I had the choice, I would never go back to a tank again but I would get a better water heater so the temperature stays within a few degrees.

I love this water heater. I installed it myself. I have experience in plumbing, so I decided to save money by installing it myself. The install was what I expected since I have installed these before. This water heater is very quite, so I was surprised to hear about all of the people saying it is too loud. It is very quiet. You can barely hear it if you are next to it. In fact, I thought there was something wrong with it since it was so quiet. I highly recommend this water heater, you will save money and space.

I have a small towel closet behind the shower and chose this water heater because it would just fit in the small space. Was concerned it may be too small. Replaced the shower head with a Delta saver model and with the saver head I can take a comfortable shower and there is still plenty of hot water when I'm done. The project ended up being a huge improvement over the old water heater that was installed about as far away from the center of the house and the shower as it could have been. It has been so nice to have instant hot water for the shower instead of waiting and waiting for hot water with the old setup. The unit was well made and installed with no problems. The unit was designed to be used as a point of use but I removed the old water heater and installed a cloths dryer in it's place. The little water heater is providing hot water to the kitchen, main bath and washer. As long as it gets time to recover it has been able to do it all. Wish I had installed it years ago

So far so good. Semi difficult install as some of the fittings required adapters to work with a standard water heater setup. Nothing several trips to the hardware store couldn't solve. Unit did not fire up the first time after install. Error 11 came on even though the unit had gas water and power. Opened the unit up and found that the AC converter had fallen lose and disconnected. Also a pipe was loose. Once these were fixed it fired right up.
