If the price of electricity is 5 cents per kWh, the low-flow shower head will save $32.50 per year per person. So, for a family of four, the cost savings of using a low-flow shower head is $95.20 per year if natural gas water heating is used, and $130 per year if electricity is used for water heating.
The average US household can save about 2,900 gallons of water every year simply by installing a single low-flow showerhead.
Benefits: Low flow shower heads can decrease water consumption by 40% or more! This not only conserves water, but it cuts down on your monthly water bill providing significant end-of-year savings. Showers take energy to heat the water, thus cutting down on water usage also cuts down on energy usage.
Install Flow Restrictors
Flow restrictors belong on all bathroom and kitchen faucets. Each one can save you up to 5,000 gallons, or about $10 every year.
A water efficient showerhead can save more than 26 litres of water for an average 7 minute shower, which is more than 9,000 litres of water per person in the household per year.
A standard showerhead uses 2.5 gallons a minute, or 25 gallons for 10 minutes. Either way, the shower saves water – as long as you don't go past 10 minutes. The shorter the shower, the greater the savings.
Try reducing the length of your shower by a minute or two a few times a week. You could also turn the flow off while you apply shampoo. Fitting a water-efficient showerhead is another great way to make savings. They use around six litres of water a minute, which is half the amount of a standard showerhead.
Decreased water waste - Low flow fixtures are specifically designed to limit water waste. The average low flow fixture expels around half the gallons per minute than a standard fixture. Add that up over time, and you can save about a thousand gallons of water per year!
While it is possible to remove flow restrictors from shower heads, we strongly advise against it for several reasons. Flow restrictors for faucets are an integral part of most aerators and it is generally not possible or desirable to remove them.
Low-flow showerheads and faucets cost $10 and upward, and they can reduce your water use by 30 percent to 50 percent. Resulting savings in water use and hot water heating can be $50 to $90 or more a year, just by installing a couple of water-saving fixtures.
A study by the American Water Works Association found that, on the average, we take eight-minute showers. If you take an eight- minute shower using one of those showerheads, you will use 48 to 64 gallons of water. That 15-minute shower will use 90 to 120 gallons.
After all, it needs certain amount of water to remove the soap, that is physic. Studies have shown that 1.8 gpm is the minimum flow rate to have a good enjoyable rinsing, so the common 1.75 gpm models, is somewhat good enough for a decent shower. To save water further and still have a full enjoyable rinsing experience.
A 2.5 gpm shower head will have a better pressure and shower experience than a 1.5 gpm shower head. A 1.8 gpm shower head would have a better pressure and shower experience than a 1.0 gpm shower head. Another drawback of low flow shower heads boosting the pressure is the temperature instability.
Also known as "flow rate", GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
If you're looking for the most pressure, go for the 2.5 GPM Flow Rate, unless you are restricted because you reside in California, Colorado or New York. Again, this has been the Maximum Flow Rate since 1992.
The average bath uses about 80 litres of water. Over the course of four minutes a normal shower head produces about 36 litres.
In low-pressure supply lines, flow restrictors provide comfort of use, and they save energy in high-pressure supply lines. By managing water flow, a flow restrictor prevents built-up pressure from damaging pipes, appliances, and fixtures.
A major advantage of simple laminar-flow restrictors is that they endow the bearing with the greatest tolerance to manufacturing variations on bearing clearance and to variations in operating temperature.
No matter what pressure you have in your house, the flow restrictor only lets through a certain amount of water. If you have really low water pressure in your home and you have a shower head flow restrictor, you might get even less water pressure than you're supposed to.
All bathroom faucets must have a flow rate that does not exceed 1.5 gpm (5.7 liters per minute [lpm]) at a pressure of 60 psi (414 kPa) at the inlet when water is flowing; a flow test does not exceed 0.25gal.
Replacing old, inefficient faucets and aerators with WaterSense labeled models can save the average family 700 gallons of water per year, equal to the amount of water needed to take 45 showers.
Please keep in mind that all new faucets since 1994 are restricted to conserve water per EPA code mandates. Older faucets had no restrictions. Beyond intentional flow restriction, new installations can sometimes have reduced flow if the lines are not flushed prior to installation of aerators or shower heads.
At the end of your shower, simply blast yourself with cold water for 30 seconds, followed by hot water for 30 seconds, and then finish with cold water for a final 30 seconds. The rapid change in temperature will open up the capillaries, increase blood flow, and stimulate the body and mind.
Low budget options include solid surface, fiberglass, PVC laminate, and acrylic, while glass, marble, granite, and natural stone tiles are premium shower wall materials.

But you generally pay a lower unit rate for electricity used between 10pm and 8am. Off-peak hours for Economy 10 customers vary as well so it's worth checking with your supplier what they would be.
