Electric showers can help you save on your monthly water and electricity bills without forcing you to sacrifice on comfort. Designed to heat water on demand, a “power” shower ensures you have a continuous flow of hot water – no matter how many people are waiting in line to shower.
Let’s take a closer look at how these showers work.
How Do Electric Showers Work?
Mixer showers can be hard to control (if someone flushes or runs water elsewhere in the house, the shower water gets colder or hotter). The hot water also comes from a tank, which can run out rather quickly if it’s small. And once you’re out of hot water, you have to wait for the tank to refill.
Electric showers overcome this dilemma by heating cold water on demand using electricity. With an endless supply of hot water, these showers are ideal for large households.
Some of you may be wondering: Aren’t these showers dangerous? After all, water and electricity is a dangerous combination.
But when installed properly, these showers are perfectly safe for use. The heating element is enclosed in its own sealed unit, and the water never comes in contact with electricity.
How Water is Heated with an Electric Shower
Power showers work in similar ways to other electronic appliances. To heat up, an electric current is sent through a piece of metal, known as a heating element. The metal piece has a relatively high level of resistance, so it heats up as electricity moves through it.
As the cold water moves past the element, it heats up and is pushed out of the shower nozzle.
Homes with high water pressure are the best candidates for power showers. The shower unit will naturally reduce the water pressure as it flows through, so homes with poor pressure may not be suitable for this type of shower.
Note: If you don’t have high water pressure, you can opt for a power shower that uses an electric pump to boost the water pressure. The pump, however, uses 3-5 times the amount of electricity that ordinary showers use.
The great thing about electric showers is that you can adjust the thermostat to a precise temperature, so your shower is never too hot or too cold. Most models have a built-in temperature dial with a clearly-marked scale that runs from blue to red.
With basic electric shower nozzle, this dial controls how much water passes by the element. The more water, the hotter the temperature.
Newer models use a water mixing tank, flow sensors, thermostats and pressure-balancing valves to help maintain the desired temperature and water flow.
It can be a challenge to maintain water temperatures, particularly in the winter and summer when outside temperatures plummet or skyrocket respectively.
With the right setup, you won’t be able to tell the difference between a conventional and electric shower – aside from the endless supply of hot water. If you’re looking to save on water and your electricity bill, an electric shower can help you reach your goal.
