Hi scarab42 and thank you for your question. It can not be determined with the information you have given. Please call 800-432-8373.
Thank you for asking. For assistance with your water heater please contact us directly 866-279-4566.
Hello Ben, Thank you for asking, I apologize you weren't able to get the insights you required. The only deduction that I was able to come to was that the geometry of the tank would effect the efficiency of the unit. Shorter but wider unit would have more surface area in which the heat is radiating into. a Taller but thinner vessel allows the hot water to rise up away from the cold water more efficiently as there is less surface area on a horizontal plane. I hope this helps.
Thank you for asking. For assistance with this question please contact us directly 800-431-1549.
Depending on how far north you live you may be able to install it outside but I don't think it is meant to be in subzero temperatures. You may also want to check your local housing/building codes to see if this is permitted where you live.
Contact the Rheem parts department. Make sure you have a Rheem certified plumber install it or you'll risk voiding the warranty
Thank you for asking, Whale. It is possible your water heater requires a new element. Please have someone contact us at 1-866-279-4566 with a Digital Multimeter to diagnose the unit. Thank you and have a great day.
The temperature of the water in the heater is regulated by the adjustable surface mounted thermostat(s) located behind the jacket access panel(s). Dual element heaters have two thermostats. To comply with industry standards the thermostat(s) were set at 120°F before the water heater was shipped from the factory. Canadian models are set to 140°F (60°C). See page 15 of the Use and Care Manual which is a PDF file on the product page to the right of the "Product Overview"
