I'm thinking of installing a rain shower head in our new bathroom, but I want to comply with our energy- and water-savings schedule. Are there any shower heads on the market that also have a good WELS-star rating?

Rain showers used to have a reputation for being heavy on water use, but the latest models benefit from technological advances. "One of the newest shower heads on the market is the three-star Kiri Drencher with Satinjet technology," says Sonia Pace, Brand Manager of Methven. "The Drencher can be fitted to either a wall or ceiling arm and it does what the name suggests: two jets of water hit each other as they're expelled through the holes, giving you a powerful drenching with its water-efficient spray." The Drencher uses Satinjet technology (where twin jets of water collide to create thousands of droplets per second) to deliver up to nine litres of water per minute, as opposed to 20 litres from an older-style shower head.
