What it delivers
The BJLIFE GJK982 3.5 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 3.5 kW on 110 volts.
Worked out from its input, it delivers roughly 0.5 GPM when the water only has to rise 45°F, and 0.3 GPM at a 70°F winter rise: less than one 2 GPM shower in summer, less than one 2 GPM shower in winter. Try your own inlet temperature.
At 110 volts 3.5 kW is about 32 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.
Other listed details: connections: 1/2" npt; material: Copper, Plastic, Stainless Steel; model: GJK982.
The listing gives dimensions of 2.7 in (W) x 3.9 in (H).
