Why are Water Efficient Shower Heads not Suitable for Electric Showers?

You’re probably already taking various types of action around the home to become more water aware and improve your efficiency. You also probably know that your biggest area for making potential savings is the bathroom.

However, you might be mystified to discover that water efficient showerheads aren’t suitable for an electric shower. Admittedly, it doesn’t make a great deal of sense on the surface that a modern product doesn’t appear fit for a modern initiative. Thankfully, there’s more to this situation than meets the eye.

Taking the Heat
The first consideration is the energy that electric showers use to heat water to a comfortable temperature. In general, when people think of showers they’re only concerned with water usage, and don’t often consider other energy use attached to them.
The energy electric showers use in heating water has a direct impact on the water flow itself. An electric showers’ flow is usually between 3-9 liters per minute, with the average right in the middle at 6 liters per minute.

Even the best water efficient showerheads will only limit water flow to around 7.5 liters per minute, although they sometimes go as low as 6. As a result, fitting a water efficient showerhead won’t actually have any impact!

Can They Damage Your Shower?
Another problem is that water efficient showerheads can actually damage an electric shower. If you have an electric shower with average water flow of 9 liters per minute (which is good on the efficiency scale, anyway) yet try to lower it with a water efficient showerhead, your electric shower could burn itself up quickly.

Electric Showers & Showerheads: The Lowdown
On the face of it, an electric shower seems like a great purchase. This is primarily because you don’t need to buy anything else, as they are already highly efficient with water use.

However, the hidden devil, if you like, with electric showers is the energy they use to heat the water. Taking a 6-minute shower uses the equivalent energy of a light bulb being switched on for 24 hours. If you’re going to go for an electric shower, then short and sharp is the way to approach showering, as your shower will be the biggest energy-consuming appliance at home.

If you have any other type of shower, then a water efficient showerhead is a great purchase to make, but you should still be mindful of the time you spend showering!
