Our take on the Westinghouse Apolo 11KW Electric Tankless Water Heater

The Westinghouse Apolo is a compact electric tankless water heater rated at 11 kW on 240 V. It mounts on a wall in about 9.5 by 14.2 inches and weighs under 12 lb, so it fits where a tank cannot. At 11 kW it delivers roughly 1.5 to 2 gallons per minute, enough for a single low-flow shower or a sink in a mild climate, not for a whole house in cold water. It is a simple point-of-use unit with no tank to run out; rivals at this power level offer similar output, and some add digital temperature setting or higher kW for whole-home use.

Pros
  • Compact wall-mount body fits tight spaces
  • No tank, so no standby heat loss and endless flow at low demand
  • 11 kW output suits one fixture at a time
  • Light at 11.7 lb, simple to hang
  • 240 V wiring is standard for electric tankless
Cons
  • About 1.5 to 2 GPM, so one fixture at a time
  • Struggles with cold inlet water in northern winters
  • Needs a dedicated 240 V circuit and heavy-gauge wiring
  • No digital display or precise temperature control on the base unit

Questions and answers

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.
Where is the Westinghouse Apolo 11KW Electric Tankless Water Heater cheapest?
At The Home Depot, for $233.99, as of our latest check.
