What electrical service does a 27kW tankless heater need?

At 240V, 27,000W draws roughly 112 amps. Plan on several dedicated 240V circuits and a service panel with that much spare capacity; an electrician should size the wire and breakers.

How many showers can it run at once?

The brand does not publish a flow rate or temperature-rise chart, so there is no verified figure. A 27kW unit is generally sized for whole-house use, but confirm capacity with an installer before relying on simultaneous hot-water use.

Is it really tankless?

The listing text and highlights describe a tankless on-demand heater, while one spec field says tank. The product name, description and features all point to tankless; treat the tank field as an error.

How does it compare with brand-name tankless heaters?

Output is in the same high range as premium electric tankless models, but established brands publish flow ratings and carry multi-year warranties. This one offers a 30-day limited warranty and no flow data.

What is included and how hard is installation?

The listing mentions clear instructions and low maintenance but does not itemize the box. Installation is not a DIY job at this power level; budget for a licensed electrician and any panel upgrades.

Our take on the Yichuhaoxi 240V 27000W Tankless Electric Water Heater

The Yichuhaoxi is a 240V tankless electric water heater rated at 27,000W, meant to heat water on demand for a whole house. It mounts on a wall, shows the set temperature on an LED display, and adds overheat protection with automatic shut-off. That output is high for an electric tankless unit, but 27kW draws about 112 amps at 240V, so it needs heavy dedicated circuits and a large electrical service. Rivals in this class from established brands offer the same on-demand idea with longer warranties and documented flow ratings; this one carries only a 30-day limited warranty and no published flow rate.
