What Is An Aerator Shower Head?

An aerator shower head is designed to reduce your demand for water while producing a more vigorous shower experience. It simply screws in while replacing your old shower head.

They are available as rain, fixed, hand-held, and combination designs. Find one to match the finish of your existing taps in traditional chrome, brushed nickel, bronze, or the latest decor trend.

How Do Aerator Shower Heads Work?

Aerator shower heads draw in the surrounding air through vents at the top and mix it with water being channelled through aerating nozzles. This makes the droplets larger which makes it feel like you are standing under a more powerful shower.

Lower Your Water Bill

This is a key consideration if your water usage is metered. Regular shower heads simply propel water through their shaped nozzles and will consume up to 30 litres of water per minute.

You may find a simple aerator shower head with a single setting that uses as little as 7.5 litres per minute. Adjustable aerators may increase water usage to 20 litres per minute to create a massaging pulse. You can see that you could reap a metered savings of more than 50%! Considering that your shower statistically represents almost 20% of your overall water usage, this is a big plus.

Enjoy A More Luxurious Shower Experience

If you have low water pressure, it may help you feel like you are getting a better shower by combining the air and water which requires greater force to push the larger droplet through the nozzle. However, the pulsing massage settings would not produce such a pleasing result unless you add an electric shower or additional pump to build pressure.

Lowers Your Electric Bill

How does a shower head reduce your utility bill? If you are using more than 50% less hot water during each shower, you won’t be paying to heat all that water. It may only appear as a pound every other month, but that starts to add up over time. When you consider that the cost of a new shower head can be as low as £5, it doesn’t take long to earn back your investment.

Some Minor Drawbacks When Using An Aerator Shower Head

Just like any modern invention, there are often trade-offs for every home upgrade. The most common thing that new users of aerators notice is that they have to turn up the heat on their showers. The aerator blends your nicely heated water with room temperature air. That results in cooler water striking your skin. You may use a little extra energy to heat your water by a few degrees, but you are still heating less of it.

If you are looking at the aerator shower head as a cheap solution to very low water pressure, you may be disappointed. It uses no motors or mechanical devices to combine the air with the water, so if you only get a dribble with a regular shower head, the aerator may do little more than create a pleasing mist.

Finally, you will notice that it takes a little longer for the temperature to change when you turn up the heat. However, after using the shower head for a few weeks, you may forget that it was ever any different.
