What it delivers
The SIVUATEK TSB-140 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 3.3 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. Check your house in the planner.
At 240 volts 14 kW is about 58 amps. The maker calls for 1 x 60-amp circuit breaker. A licensed electrician confirms the panel, the service and the wire before it goes in.
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: TSB-140.
The listing gives dimensions of 12.2 in (W) x 17.25 in (H) and a weight of 6.85 kg.
