What it delivers
The Westinghouse WET011A0G 11 kW Electric Tankless Water Heater is a compact electric tankless rated at 11 kW on 240 volts. Its listing gives a maximum flow of 2.6 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 1.7 GPM at a 45°F rise, falling to 1.1 GPM at 70°F, which is less than one 2 GPM shower on a cold-climate winter day. Check your house in the planner.
At 240 volts 11 kW is about 46 amps. The maker calls for 60A double-pole breaker. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
Electric tankless units need no venting and no gas, and work best where inlet water stays mild, because every degree of rise costs flow.
Also on the listing: connections: 1/2" npt; connectivity: WiFi; material: Sheet Metal; model: WET011A0G.
The listing gives dimensions of 9.56 in (W) x 12.59 in (H).
