What it delivers
The ECOAPTUNIT LF-002A 5.5 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 5.5 kW on 220 volts. Its listing gives a maximum flow of 0.8 GPM.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 0.8 GPM, less than one 2 GPM shower; in winter, at a 70°F rise, about 0.5 GPM, less than one 2 GPM shower. Size it to your fixtures.
At 220 volts 5.5 kW is about 25 amps. Whether your panel can carry it alongside heating and cooking loads is an electrician's call.
It's meant for a single fixture near the unit: it saves the wait for hot water there rather than heating a whole house.
From the listing: connections: 1/2" npt; material: ABS, Glass, Stainless Steel; model: LF-002A.
The listing gives dimensions of 5.7 in (W) x 8.5 in (H).
