Make sure that in case of freezing weather that the water heater and its water lines are protected to prevent freezing. Damage due to freezing is not covered by the warranty.With electrical power and gas supplied, the water heater will not freeze when the outside air temperature is as cold as –22°F (-30°C) for indoor models or is as cold as –4°F (-20°C) for outdoor models, when protected from direct wind exposure. Because of the “wind-chill” effect, any wind or circulation of the air on the unit will reduce its ability to protect itself from freezing.In the event of a power failure and/or gas interruption at temperatures below freezing the water heater should be drained of all water to prevent freezing damage. In addition, drain the condensate trap and drain line.Loss of freeze protection may result in water damage from a burst heat exchanger or water lines. The unit may be drained manually. However, it is highly recommended to:drain down solenoid valves be purchased and installed that will automatically drain the unit if power is lost. These are available in a kit, 104000059. (The condensate trap is not affected by the auto drain down solenoid valves and will have to be manually drained.)a surge protector with terminals be purchased and installed which allows the solenoid valves to operate if the unit is disabled due to a diagnostic code. This is available as 104000057.In addition, the solenoid valves should be connected electrically to a surge protector with terminals. This allows the solenoid valves to operate if the water heater is disabled due to a diagnostic code. The freeze protection features will not prevent the external piping from freezing. It is recommended that hot and cold water pipes be insulated. Pipe cover enclosures may be packed with insulation for added freeze protection. --Tashay

We don't get hot water on demand. The kitchen sink
I like the small size of it. We had a Rinnai before for 20 yrs. We didn't have the problem with getting hot water. The new model does not meet our expectations.
by Newernotbetter1596
Great investment
I went from an electric tanked water heater. My electric bill was sky high and I was always taking a cold shower at the end of the day. I’ve had the new water heater for about 6 months. My electric bill has been cut by more than half and I haven’t ran out of hot water once.

It works great. It is very efficient and you never run out of hot water unless you loose power.
by Sam
Limitless hot water
This is our first tankless hot water system and we love the fact that we do not run out of hot water when we have a full house, yet when the house is empty for weeks at a time, we are not keeping a tank full of water hot at all times. It is also far more compact than with a conventional tank.
by Bethanybeachhouse6875
Best Ever !! Great investment
It is small and doesn’t take up a lot of room , I like that the temperature can be set on the system. It is quite. I’ve had it about 3 months, I notice my bill is lower with this unit. It works great !
