Our take on the Westinghouse 3500W Electric Tankless Water Heater

A compact point-of-use electric tankless heater that runs on 120V and delivers hot water on demand at a single sink or shower. It heats only while water flows, so there is no tank to keep warm and no standby loss. Output is modest, so it suits hand sinks, small cabins, RVs and supplemental use rather than whole-house supply. Compared with larger 240V tankless units, it installs on ordinary household wiring but cannot match their flow at cold inlet temperatures.

Questions and answers

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.
Where is the Westinghouse 3500W Electric Tankless Water Heater cheapest?
At The Home Depot, for $179.99, as of our latest check.
Where can I buy the Westinghouse 3500W Electric Tankless Water Heater?
