What it delivers
The Camplux TE04N3 3.5 kW Point-of-Use Tankless Water Heater is a point-of-use electric tankless rated at 3.5 kW on 120 volts. Its listing gives a maximum flow of 2.5 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 0.5 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. Check your house in the planner.
At 120 volts 3.5 kW is about 29 amps. The maker calls for 32A Circuit Breaker. 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: connections: 1/2"npt; material: Aluminum, Stainless Steel; model: TE04N3.
The listing gives dimensions of 7 in (W) x 6 in (H) and a weight of 3 lb.
