How much power does the Atami need?

It is a 27 kW unit, so it draws very high current. Most homes need multiple dedicated circuits and a large electrical service to run it.

Is it enough for a whole house?

At 27 kW it can serve several bathrooms and high-flow appliances, but only if the electrical panel supports it. In cold climates, incoming water temperature lowers its output.

Does it need a tank or venting?

No. It is tankless and electric, so there is no storage tank and no gas venting. It mounts on the wall and heats water as it flows.

The unit itself with its mounting hardware and display. Electrical wiring, breakers and plumbing fittings are not included and are usually supplied by the installer.

How does it compare with gas tankless heaters?

Electric units avoid gas lines and venting, which simplifies placement. Gas tankless models generally deliver more output for very cold water and high simultaneous demand.

Does it work during a power outage?

No. It needs electricity to heat water, so it stops working when the power is out.

Our take on the ANZZI Atami Tankless Electric Water Heater

The ANZZI Atami is a 27 kW whole-house tankless electric water heater. It heats water on demand, so there is no tank to keep warm and no standby loss. The 27 kW rating puts it among the more powerful electric units, enough for several bathrooms or a large family when the home has the electrical service for it. It is compact and wall-mounted with a digital display and smart temperature control. Reviewers rate it well overall, though some note the heavy electrical demand and installation cost.
