Questions and Answers for Rheem ProTerra 80 Gal. 10-Year Hybrid High Efficiency Heat Pump Tank Electric Water Heater with Leak Detection & Auto Shutoff

A:  Hi hitechrr and thank you for your question. The anode is - AP11526T-2 Description: Anode Rod - 0.900 in. diameter x 39-3/8 in. long - Magnesium

A:  Hi DanL and thank you for your question. No it does not. Mixing valves are recommended for reducing point of use water temperature by mixing hot and cold water in branch water lines. It is recommended that a mixing valve complying with the Standard for Temperature Actuated Mixing Valves for Hot Water Distribution Systems, ASSE 1017 be installed. See page 3 for more details and contact a licensed plumber or the local plumbing authority for further information.

A:  If a mixing valve improved efficiency, all water heaters would have one built in. Keeping the tank at a higher temperature will increase the stand-by loss. Studies I've read say for a new install, to go for a larger tank instead of using a mixing valve.

A:  Hi JRCM and thank you for your question. The Recommended Over Current Protection (Fuse or Circuit Breaker Amperage Rating) is 30.

A:  Hi Roscoe and thank you for your question. You would use the front panel to change. If you are having issues, please call the number on your unit or in your user manual.

A:  Nothing in the manual limiting temp settings per mode. Enable high temps >140° by pressing & holding both "UP" and "DOWN" buttons for 3 sec. *Max Temp: 150°F.

A:  Hi ChrisM and thank you for your question. Please contact your local outlet about purchases and any discounts / rebates applied.

A:  Hi LeeB and thank you for your question. I am sorry, but that information is proprietary.

A:  Hi PASS and thank you for your question. No it does not. Please follow the guide in the user manual on the link you provided. This information starts on page 5.

A:  Hi HeatpumpsFTW and thank you for your question. The XE65T10HS45U0 has Leak Detection & Auto Shutoff.

A:  Hi Rosa and thank you for your question. Yes it would be.

A:  Hi Whozit22 and thank you for your question. The Ducting Requirements Always check with local building and HVAC codes before designing the duct system The water heater may be ducted to the outdoors or another space as described in these instructions. Ducting configurations that does not comply with these guidelines are not supported. DO NOT connect this water heater to existing duct work; it must be ducted separately from other appliances. Ducting approved for HVAC applications is required. Ducting must be adequately supported along both vertical and horizontal lengths. UL Certified terminations must be used for ducting to the outside. These terminations have been evaluated to ensure there is sufficient protection from rain water entry and resistance to air flow is minimized. Indoor registers approved for HVAC applications is required. Rigid ducting must be isolated from f loor joists or other structural members to minimize the transmission of noise and vibration. A short section (12 inch minimum) of flexible duct must be used between the water heater and rigid ducting as an isolation method. Every foot of flexible ducting counts as three feet of rigid ducting. Ducting must be insulated per HVAC codes (to prevent condensation). Ensure cold air exhaust is sufficiently away from structures to prevent condensation on surfaces. Maximum heater performance is obtained by lowering the resistance to air flow (regular filter maintenance is beneficial) and providing the unit with warm moist air. Considerations when planning the duct system:  Run the ducting the most direct route possible.  Limit the number of elbows/bends.  Use the largest duct size possible.  Use the largest termination possible.  Consider placement and direction of terminations (reduce recirculation of exhaust into the intake)
