What it delivers

The Westinghouse HEU-ET014KA1G-A2 14 kW Electric Tankless Water Heater is a compact electric tankless rated at 14 kW on 240 volts.

Flow depends on how cold the incoming water is. Our estimate from its input: 2.1 GPM at a 45°F rise, falling to 1.4 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 14 kW is about 58 amps. The maker calls for 60A breaker. 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.

Also on the listing: features: Dry Combustion Protection, Overheat Protection, Self-Modulating; connections: 1/2-inch NPT; connectivity: WiFi; model: HEU-ET014KA1G-A2.

The listing gives dimensions of 8 in (W) x 11 in (H).
