Installation requires 240 volts, so it works best in homes with the right electrical setup.

Its recovery rate is good for small applications but won’t deliver large volumes of hot water quickly compared to bigger or higher-powered units. This Rheem model is a solid pick if you want an energy-saving, compact electric water heater for individual sinks or small uses, while it might not suffice for larger households or high-demand situations.
