- Can it run a shower?
- Only a low-flow shower in a warm climate. At 120V its output is small, so cold inlet water will leave the shower lukewarm.
- Does it need a dedicated circuit?
- Yes. A 3500W unit draws about 29 amps at 120V, so it needs its own properly sized breaker and wiring.
- How is it different from a 240V tankless heater?
- 240V units deliver far more power and can serve a whole home. This one is a point-of-use heater for one fixture.
- Where can it be mounted?
- Its IPX4 rating allows damp spots such as under a sink or in a utility area, following the manufacturer's clearance guidance.
- Is it good for an RV or cabin?
- Yes, for a sink or outdoor shower in mild weather. Expect limited flow and cooler water in winter.
