What it delivers
The Midea MHE13W2AWW 13 kW Electric Tankless Water Heater is a compact electric tankless rated at 13 kW on 240 volts.
Worked out from its input, it delivers roughly 2.0 GPM when the water only has to rise 45°F, and 1.3 GPM at a 70°F winter rise: less than one 2 GPM shower in summer, less than one 2 GPM shower in winter. Try your own inlet temperature.
At 240 volts 13 kW is about 54 amps. The requirement calculator shows it at 208 V too; an electrician confirms the panel.
Electric tankless units need no venting and no gas, and work best where inlet water stays mild, because every degree of rise costs flow.
Other listed details: features: Overheat Protection; connectivity: Smart Control; material: Copper; model: MHE13W2AWW.
The listing gives dimensions of 11.38 in (W) x 15.75 in (H) and a weight of 6.8 lb.
