Rheem, as well as other WH companies, often use this for their warranty. A commercial heater, installed on a residential setting will not necessarily have a warranty, as it isn't installed per manufacturer's instructions. Same thing goes, when you install a residential heater, in a business. Just keep that in mind, if you purchase this for the lifetime warranty. And especially the past year, Rheem has started following through with this. So, now you're warned.
An expansion tank is only needed when you are on public water and have a check valve at the water main. Otherwise if you are on a well, an expansion tank is not needed as an expansion tank allows for the expansion and contraction of the water as it heats up and cools down. on a well the pump tank will double as an expansion tank.
Each 4500 watt element is equivalent to 15,354.639 BTU/Hr on this water heater.
30 amp. I believe you should only use 80% so 30 amps X 80% is 24 amps. 20 wouldn't be enough.
yes, it would be compatible with a Jacuzzi, However, i'm not sure of the capacity of the tub in question. so i would verify that this unit would meet your needs as far as gallons needed to fill the tub.
From the Rheem website for the MHD models. "Titanium upper and lower elements for superior resistance to lime build-up" rheem.com/product/commercial-electric-water-heaters-marathon-heavy-duty
It does not have a lifetime warranty only 5 Years tank and 1 otherwise.
Yes. Two simple dials for each element (top and bottom).
Yes. I used shark bite on my install.
