Shower Heads

For the House

HOW DOES IT WORK?

Energy efficient showerheads, taps and toilets work by reducing the amount of water flow compared to the old style systems. This will not only save water usage (and thus save money) but for items using hot water, it will reduce the amount of hot water required, which in turn reduces the amount of work your hot water system is doing and saving you further on energy consumption.

HOW MUCH CAN I SAVE?

The new efficient showerheads use about 9 litres of water per minute, a reduction from 20 litres per minutes with the older style. This in itself creates a significant saving but let’s assumes your hot water system mixes 50% hot water with 50% cold for your usage in the shower. If the water usage has reduced by over 50% then is fair to assume your hot water associated power usage will reduce by an similar amount.

Typical taps discharge 15 to 18 litres per minute compared with low-flow and aerating models which use as little as 2 litres per minute depending on the intended application and taps with an aerator or flow restrictor may reduce flow to less than a third of standard taps.

An old-style single flush toilet can use up to 12 litres of water in one flush, whereas more water efficient dual flush toilets average less than four litres. A single flush toilet costs around $760 over ten years to operate compared with a water-efficient dual flush cistern which costs around $250 over ten years to operate or a 67 per cent reduction. Replacing a traditional single flush toilet with a water efficient dual flush toilet saves about 51 litres per person per day and using a water efficient dual flush toilet reduces household water use by around 30,000 to 40,000 litres per household per year.

HOW MUCH DOES IT COST?

The showerheads can be very cost efficient, ranging from the entry level of $15-$30, to the higher end styled costing a couple of hundred dollars each. Given the potential energy savings made each year it is a very worthwhile purchase.

Taps and mixers start at around $60-$70 for the base models but are also available in various styles, colours and configurations to suit each application.

Dual flush toilets can start from under $200 and are worthwhile investments considering the potential savings. There are many styles and varieties available in energy efficient models.

MORE INFORMATION

Installing a water-efficient showerhead (if compatible with your hot water system) will give you a great shower and you’ll save water, energy and money. Standard showerheads use about 15 to 25 litres of water per minute. Water-efficient showerheads use nine litres per minute or less.

Installing a water-efficient showerhead could save thousands of litres of water per year.

This means:

  • reduced water consumption — saving on your water bill; and

  • reduced energy consumption for hot water — reducing your energy bill and greenhouse gas emissions.

The more time spent in the shower and the more the tap is turned on, the greater your water consumption. So, whether you have a water-efficient showerhead or not, shorter showers using less water pressure will reduce water use and assist in reducing your water bill.

Hot Water System Compatability

Water-efficient showerheads can help many households save significant amounts of water, energy and money. However they are not suitable with some hot water systems. If you have an instantaneous water-heating unit, check with the heater manufacturer—the reduced flow rate of some water-efficient showerheads may be too low for some heater models. If you have a gravity-fed hot water unit, check with the showerhead manufacturer—not all showerheads will deliver enough water if your water pressure is too low.

To Check the Flow Rate of Your Showerhead

You will need a bucket, a one-litre measuring container (such as a one-litre milk carton or measuring jug) and a watch that shows seconds.

  • Fully turn on the cold-water tap of your shower.

  • Hold the bucket under the shower for 20 seconds.

  • Remove the bucket and turn off the water.

  • Measure the amount of water in the bucket by emptying a litre at a time into the measuring container.

  • Calculate the flow rate (in litres per minute) by multiplying the number of litres by three. For example, if you collected 8 litres over the 20 seconds, the flow rate is 8 x 3 = 24 litres per minute.

Water-effcient showerheads have a flow rate of nine litres per minute or less.

Water Efficiency Labelling and Standards

A new national compulsory Water Efficiency Labelling and Standards (WELS) Scheme has replaced the voluntary ‘AAAAA’ labelling scheme. On 1 July 2006, it became mandatory across Australia for showers; clothes washing machines; dishwashers; toilet equipment; urinal equipment; and tap equipment intended for use over kitchen sinks, bathroom basins, laundry tubs or ablution troughs, to carry a WELS Water Rating label when they are offered for sale. Flow controllers may also carry a label, but this is not mandatory.

The WELS Water Rating label has:

  • a star rating that gives a quick comparative assessment of the model’s water efficiency; and

  • an estimate of the water consumption of the product.
