The battery box stopped working and the hot cold water very hard to control flactuates between very hot extereme cold.
You have turn on and off to control or adjust water temperature even when it’s working.

Marey GA10NG 3.1 GPM Tankless Water Heater

Works great. Had to play around with adjusting the hot water because it is really hot!!. Easy to install. Love the instant hot water.

Easy to install, but requires relatively large water flow to trigger the fire

My 2nd floor bathroom's water pressure isn't very high. If I turn the hot water all the way up the water heater will heat the water but the water will be way way too hot(even if I put the heating knob to the lowest setting). But when I turn the water from hot to warm(mixed hot water with cold water), because of the water pressure not high enough, the water heater will shut down and the water will become too cold. So it's either way too hot or way too cold. The only way I can solve this is to open another hot water faucet in the bathroom, to keep the hot water flow big enough and keep the fire on. This is not only a hassle but also a waste of hot water. I wish the manufacturer can add more range to the setting so the hot water flow can be triggered with less flow.
