The Eemax PA020277TC is a 277V electric tankless water heater rated at 20 kW, built as a twin-module thermostatic unit. It heats about 2.0 GPM with a 69°F temperature rise, so it suits point-of-use jobs like a single sink or a small commercial fixture rather than a whole house. It draws 72 A over two 36 A circuits and needs 8-gauge wire, so the electrical work is the main cost. Against gas tankless heaters it needs no venting, but it delivers less hot water at once and depends on a 277V supply that most homes don't have.
