outdoor water heater

has anyone had experience with outdoor water heaters, for space and venting problems i really wanted to try one, it supposed to have freeze protection to 20 below, my question is how are these in cold climates i live in pa and we do get at least 1 or 2 months of really cold weather, i only found 1 article of someone in utah installing them, i am going to use heat tape and insulation for the piping but my concern is the unit itself, what additional protection for the unit can i use. the heater is the rheem 53xp any advice would be greatly appreciated.

As long as the heater is turned on and operating properly, it won't freeze.

You could wrap the outside in an approved insulation blanket to reduce energy consumption keeping the water hot enough.

Stop wasting time re-adjusting the pattern. Have several lawn sprinklers, one for each pattern.

From pg. 7 of the installation instructions for the Rheem 53, it says:

● The water heater and water lines should
be protected from exposure to freezing

i seen that too, i talked directly to a rheem tech, and he told me the unit by itself, as long as it doesnt get colder than 30 below with the wind chill the unit will not freeze as long as there is power, he just told me to get a battery backup for power outages the unit uses 2 amps for the freeze protection. i thought about making an insulated cover for it for a little extra protection or get the recessed box rheem makes.
