- What flow rate can it handle?
- It is a point-of-use unit, so expect enough hot water for one sink or a low-flow fixture, not a shower or a whole house. Output falls as the incoming water gets colder.
- Can it run on 240V household power?
- No. It is rated for 277VAC single phase, a voltage common in commercial lighting circuits. A 240V home circuit will not match it.
- Does it need a dedicated circuit?
- Yes. An electric tankless heater draws high current and should have its own properly sized breaker and wiring installed by a licensed electrician.
- How is it mounted?
- It mounts on a wall with its compact case, roughly 10.75 inches tall and 5.25 inches wide, so it fits under a sink or in a small closet.
- Does it have a temperature control?
- This model has no user temperature dial. Outlet temperature depends on the element and the flow through the unit.
- Is it good for a whole house?
- No. It is designed for one fixture or a small point-of-use load. A whole-home setup needs a larger multi-element unit.
