From the Manufacturer

Rheem's Prestige series condensing tankless water heaters efficiently provide continuous hot water with a 0.94 energy factor. Condensing technology uses the exhaust gases to reheat incoming cold water which is why they are the most efficient whole home tankless water heating solution available. Why keep 40-50 gallons of water hot when you don't need it? It's expensive to continue to heat and re-heat water when you're not home or not using it. Rheem's Prestige tankless design offers convenience and low cost operation. Includes: Digital remote control - UMC-117 10-feet thermostat wire For outdoor use only.

Verified Purchase
Did a lot of research before buying. VERY efficient, even temperatures, no pockets of cold water. Once the hot water hits whatever room you're using it, count on it running forever! Can't believe how hot 120 degrees could be. Just make sure you check on any necessary upgrades to your meter (we had an old half-pound meter that needed a 2lb regulator added by the gas company. Then we needed regulators on all our other gas appliances.) Also, make sure the installer pays attention to the condensing plug. The condensate is acidic, and many state & local codes require a condensate drain. No venting needed - which is why we chose the outdoor unit. Love this Water Heater!
