- How much hot water can an 11 kW tankless heater deliver?
- Roughly 1.5 to 2 gallons per minute, depending on how cold the incoming water is. That covers one shower or sink, not two fixtures at once.
- Can it replace a whole-house tank heater?
- Only in small homes or mild climates. For a full house with cold inlet water, you need a higher-kW unit, often 18 kW or more with two circuits.
- What wiring does it need?
- A dedicated 240 V circuit sized for 11 kW, which means heavy-gauge wire and a matching breaker. An electrician should confirm your panel can carry it.
- Does it need a vent?
- No. Electric tankless heaters have no combustion, so there is no flue or gas line, just water connections and power.
- Where is it best installed?
- Close to the fixture it serves, such as under a sink or in a closet. Short pipe runs mean hot water reaches the tap faster.
- Is it good for a cabin or rental?
- Yes, if demand is one fixture and the wiring is in place. Its small size and lack of a tank make it easy to fit and drain for seasonal use.
