Camplux/From $153

While covering your entire bathroom’s water heating is better suited for the 27kW model or its closer variants, this 8kW tankless electric water heater is still a fully capable option that can handle two faucets’ needs, with its left and right inlet/outlet design making it especially convenient for under-sink/under-counter installation. Once it is installed, it provides a water heating range from 35 degrees all the way up to 131 degrees, with plenty of safety protections and even a self-modulating flow sensor to regulate energy consumption based on the current demands. Keep in mind that it will require a minimum 0.47 GPM water flow to activate alongside double-pole 40A breakers, a wire gauge of 1 x 8 AWG, and a 1/2-inch NPT connection.
