Recirculating hot water for greater efficiency
You turn the faucet, and the shower head comes to life. You stand in the bathroom testing the water every few seconds until it's ready. This process isn't very efficient—for every minute that goes by, the shower is using approximately two gallons of water. It's not just the shower. There are probably four or five times a day that you turn the hot water tap at the sink and wait for the water to run hot. Recirculating hot water is a method to make water hot right when you need it, which can save you time and conserve your water usage.
How they work Before we talk about the environmental benefits, let’s talk about plumbing. Water runs through your house in pipes, powered by electric pumps . A tank in your house heats water , either by gas or electricity (rather like a pot of water on a stovetop), and pipes it all the way to your shower.
