What it delivers
The Eemax AM004277T 4.1 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 4.1 kW on 277 volts. Its listing gives a maximum flow of 0.3 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 0.3 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. Size it to your fixtures.
At 277 volts 4.1 kW is about 15 amps. A licensed electrician confirms the panel, the service and the wire before it goes in.
It's meant for a single fixture near the unit: it saves the wait for hot water there rather than heating a whole house.
Also on the listing: model: AM004277T; warranty: 1 Year Parts.
The listing gives dimensions of 5.25 in (W) x 14.5 in (H) and a weight of 6 lb.
Warranty, per the listing: 1 Year Parts.
