Do Water Saving Shower Heads Work?
Did you know that an older shower head can use 15-25 litres of water per minute? That means a 5 minute shower will use around 100 litres of water! You could save thousands of litres of water by installing a water saving shower head. That’s not to mention the energy and money you’ll save with reduced water usage. It’s better for the pocket and the environment, so if you haven’t got one installed already, contact Metropolitan Plumbing for our shower plumbing services.
What are Water Saving Shower Heads?
Water saving shower heads, commonly referred to as low flow shower heads, restrict the volume of water that passes through them. Modern shower heads use 9 litres per minute (L/min). You can commonly find water efficient shower heads with a flow rate of 7.5 L/min. Some are even more water efficient!
Because the volume of water is reduced by a water saving shower head, they might not be suited to homes where low water pressure is a problem, however. Similarly, if your home uses an instantaneous water heater you might struggle with a water saving shower head. In order to heat your water, a particular flow rate must be met. Some low flow shower heads might not achieve this, meaning your showers will be cold!
Types of Water Saving Shower Heads
There are two main types of low-flow shower heads – aerated and non-aerated.
Aerated Shower Head
Aerated shower heads use a combination of water and air to provide you with a pleasant flow of water. Air is sucked in through ducts to aerate the water and give the impression of a higher flow rate.
This type of shower head is very water efficient but comes with some drawbacks. Firstly, if the shower head does not drain properly, bacteria might grow in the undrained water. The next time you turn the shower on the bacteria is sprayed onto you!
Secondly, the nature of aerating your shower water will mean it feels cooler than it would otherwise. This means you might be tempted to use more hot water, thus wasting more energy!
Finally, the air ducts which suck air in can become clogged with debris and minerals from water. Over time, less air will be sucked through and more water will be used, in effect decreasing its efficiency!
Using a fully qualified plumber to install your shower head means you’ll be less susceptible to these problems.
Non-Aerated Shower Head
Non-aerated shower heads use the size of the holes to reduce water usage and save water. This creates a higher pressure shower while restricting water flow. The small holes of the non-areated shower head its responsible for its efficiency.
This shower head type is great for water efficiency, but also comes with its own drawbacks. The main one is that the overall shower experience. Non-aerated shower heads give a strong massaging water flow. While some enjoy this, many people do not.
How Much Water Do Water Saving Shower Heads Save?
The average Australian shower lasts 7 minutes. If your home is using an older shower head that uses up to 25 L/min, that’s 175 litres of water. For a 4 person home, that’s 700 litres of water a day just used on showering!
Converting to a modern 9 litre shower head alone will save a 4 person home 448 litres of water a day. Going one step further and having a 7.5 L/min water saving shower head will save you nearly 500 litres per day!
That’s 500 litres of water you won’t be having to spend money on the water and energy bill. Installing water saving shower heads will mean you can spend that extra couple of minutes in the shower guilt-free. You’ll be saving the environment with your reduced water use, as well as pocketing that money you would have otherwise spent on water and energy!
