How much hot water can a 6.5kW unit deliver?

At 6.5kW on 240V it draws about 27 amps and heats roughly 1.3 gallons per minute by 40°F. That suits a sink or a low-flow shower, not a full-flow shower or several taps at once.

Does it need a special electrical circuit?

Yes. It needs a dedicated 240V circuit sized for about 27 amps, which usually means a 30-amp breaker and 10-gauge wiring. A licensed electrician should install and wire it.

Is it a whole-house heater?

No. It is a point-of-use heater for one fixture or one small room. Whole-home tankless units run 18kW and up and need much larger circuits.

What safety features does it have?

It has overheat protection, dry-combustion prevention and separation between the water and electrical lines. It is CSA certified.

How long is the warranty?

The warranty is a 30-day limited warranty, which is short compared with the multi-year coverage on major tankless brands.

Can it be mounted under a sink?

Yes. The 7.5 x 7.5 x 11 inch body is designed for under-sink or wall mounting, but check clearance and ventilation in a closed cabinet.

Our take on the Yichuhaoxi 65kW 240V Smart Tankless Electric Water Heater

The Yichuhaoxi is a compact 6.5kW, 240V electric tankless heater meant for a single point of use, such as an under-sink tap, a bathroom basin or a small shower. It modulates its power to the temperature and flow you set and is rated up to 98 percent efficient, with overheat and dry-run protection and a scale-resistant element. It is a budget, single-fixture unit rather than a whole-home heater: at 6.5kW it cannot feed a large shower or several taps at once, and its 30-day limited warranty is far shorter than the multi-year coverage on name-brand tankless heaters.
