The Rheem Performance 8 kW is a small electric tankless water heater for point-of-use jobs: a single sink, a small bathroom, or a remote tap far from the main tank. It runs on 240 volts and a single 40-amp double-pole breaker, and its self-modulating element adjusts power to the flow so the outlet temperature stays steadier than a fixed-element unit. At 1.55 GPM it cannot feed a shower and a sink at once, so it competes with other point-of-use tankless units rather than whole-home heaters. Owners of similar small Rheem units praise the compact size and steady temperature at low flow, but installers note the dedicated 40-amp circuit and the modest output limit what it can serve.
