Will it run a whole-house shower?

No. At 3000W on 110V it is a point-of-use heater for one fixture. Expect a low-flow shower head or a sink, not multiple taps at once.

What wiring does it need?

A dedicated 110V circuit with a 30-amp breaker and wiring sized for roughly 27 amps. It should be grounded and installed by someone comfortable with electrical work.

How hot will the water get?

It depends on flow rate and the incoming water temperature. Slower flow gives hotter water; cold winter supply water lowers the output temperature.

Where can it be installed?

It is meant for RVs, kitchens, bathrooms, garages, laundry rooms and basements. The IPX4 rating handles splashes, not immersion or outdoor weather.

Does it have safety shutoffs?

Yes. It lists dry burn protection, overheat protection, leak protection and auto standby.

The heater unit itself. Mounting hardware and fittings are not listed, so check before installing.

Our take on the ZEMZYL Tankless Water Heater 110V 3000W Instant Water Heater

The ZEMZYL is a small point-of-use electric tankless heater rated 3000W at 110V. It heats water in about 3 to 5 seconds and has a digital LED display. The 304 stainless steel liner, 316L heating pipe and brass connectors are sturdier than the plastic-bodied heaters common at this size. At 3000W on a standard 110V circuit it draws roughly 27 amps, so it needs a dedicated 30-amp breaker and heavy-gauge wiring. Output is modest: it suits a single sink or shower head in an RV, kitchen, garage or basement, not a whole house or two fixtures at once.
