What it delivers
The SIVUATEK V7B-140B 14 kW Electric Tankless Water Heater is a compact electric tankless rated at 14 kW on 240 volts. Its listing gives a maximum flow of 2.3 GPM.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 2.1 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 1.4 GPM, less than one 2 GPM shower. Size it to your fixtures.
At 240 volts 14 kW is about 58 amps. 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.
From the listing: connections: 1/2" npt; material: Aluminum, Brass, Metal; model: V7B-140B.
The listing gives dimensions of 12.2 in (W) x 17.25 in (H).
