Swapping a kitchen tap is a great way for homeowners to bring their energy usage down, it has been claimed.Writing for Earth911.com, Ashley Schiller noted that energy-efficient aerator nozzle kitchen taps are excellent for reducing the amount of water waste a family produces.The ideal kitchen aerator should use no more than two gallons per minute (gpm), she explained, adding that people should look for a marking on the kitchen tap to discover what its gpm is. Those who prefer to use the dishwasher over the kitchen sink were also advised to purchase a new model if their current item is older than ten years. The initial investment will pay for itself through lower bills and superior performance, Ms Schiller continued. Earlier this month, interior architect Alicia Silvia - writing for the Seattle P-I blog - recommended a new kitchen tap to individuals hoping to boost sustainable practices in their homes.
