Instant Water Heater 5400W 110V Electric Shower Heater Instant Hot Faucet Bathroom Water Heating Instantaneous Water Heater (Blue)
  • Our shower heater is a small unit, so it obviously doesn't contain a water pump. The water pressure of your mains is the pressure with which you will get water from your shower head. The only purpose of the shower is to quickly heat cold water coming from the mains, while it runs through the shower and out of the shower head.
  • Another advantage that comes with purchasing such a shower is minimal plumbing. Since you don't need to mix hot and cold water, just one pipe connected to your cold water mains is sufficient for an electric shower.
  • Installation is very convenient:Thus, the main advantage of the electric shower is that you heat only as much water as you use, as opposed to a conventional water heater, where power is wasted heating more water than is required. This makes the electrical water heater very economical.
