What it delivers
The Daordaer LF-001A 3 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 3 kW on 110 volts. Its listing gives a maximum flow of 1.6 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 0.5 GPM at a 45°F rise, falling to 0.3 GPM at 70°F, which is less than one 2 GPM shower on a cold-climate winter day. Try your own inlet temperature.
At 110 volts 3 kW is about 27 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
Point-of-use units go under or beside one sink, where a short pipe run means hot water in seconds.
Also on the listing: features: Dry Combustion Protection, LED Display, Lightweight, Temperature Lock; material: Acrylonitrile Butadiene Styrene; model: LF-001A.
The listing gives dimensions of 4.3 in (W) x 14.5 in (H), a weight of 4 lb and comes as a combo set in the box.
