How does a power shower work?

Question

I'm particularly interested in the way in which it heats the water.

Answer 1

The shower does not heat the water. Rather, the water is heated by the house's water heater, sometimes redundantly called a "hot water heater." This appliance heats all of the water in the house, and the plumbing supplies the hot water to the shower, the sinks, and anything else in the house that uses hot water; none of those outlets actually heat the water on their own.

Some showers incorporate pressure pumps to supply water pressure. It is especially difficult to provide good water pressure at high elevations, because the water needs to originate at a physically higher point in order to be pressurized without power. When this is not possible, pumps are required. Hotels often have booster pumps at certain points in the building; you can ask the front desk what floors have booster pumps, and book your room on one of those floors to ensure good water pressure in the shower.
