Rheem Performance Platinum Tankless Gas Water Heater: What to Know
Per Rheem's own product page, this Performance Platinum model is a condensing tankless gas water heater with built-in EcoNet Wi-Fi, letting you monitor and adjust settings remotely rather than only from the unit itself — a distinguishing feature versus the other gas units in this comparison. The company states the unit includes LeakGuard, a leak detection and prevention system, and Hot-Start Programming, which Rheem describes as minimizing the brief burst of cold water some tankless units produce right when hot water demand starts.
Rheem's spec sheet lists a 0.93 Uniform Energy Factor rating and compact dimensions (17 inches wide by 23 inches tall by 9 inches deep), with the company stating this generation is up to 20% smaller and lighter than its previous version — relevant if you're retrofitting into a tight mechanical space. PVC venting is rated for runs up to 60 feet with 2-inch pipe or 150 feet with 3-inch pipe, giving installation flexibility for units not located near an exterior wall.
The unit is compatible with both indoor and outdoor installation, though Rheem notes an outdoor conversion kit is sold separately rather than included. Warranty coverage is listed as 15 years on the heat exchanger, 5 years on parts, and 1 year on labor.
