Our take on the Tankless Water Heater

A tankless electric water heater that mounts on an indoor wall and heats water on demand instead of storing it in a tank. The self-modulating element adjusts power to the flow, so it holds a steadier temperature than a fixed-output unit. It suits apartments and small homes with enough electrical capacity, and it frees floor space a tank would take. Against gas tankless models it needs no venting, but it draws heavy current and needs a large dedicated circuit.

Questions and answers

How does it compare with a tank water heater?

It heats water as it flows, so it never runs out and takes far less space. A tank stores hot water and can serve several fixtures at once on a smaller circuit.

Will it run a whole house?

Only within its electrical capacity. It handles one or two fixtures at a time well; running a shower and appliances together can cut the temperature.

What electrical setup does it need?

A dedicated high-amperage circuit, often 240 volts, sized to the unit. Most homes need an electrician to check the panel and run the wiring.

Does it need venting?

No. It is electric, so there is no flue or gas line, which is why it can sit on an indoor wall.

What maintenance does it need?

Periodic descaling in hard-water areas. Mineral buildup on the heating element reduces flow and temperature over time.

Is it good for apartments?

Yes, if the panel can carry the circuit. Its small wall footprint suits tight spaces, but check the unit's flow rating against your shower and sinks.

At Target, for $174.99, as of our latest check.
