Most people have to wait for 30 seconds or more after turning on a spigot before the water warms up. That’s a huge waste of water. In fact, the average U.S. home wastes between 12,000 to 38,000 gallons of water a year, just by waiting for cold water to run through the hot water tap before warm water starts flowing.
If you have a conventional water heater, one with a tank, your solution could be a recirculating pump.
A recirculating pump delivers instant hot water at every faucet.
Your best bet: Choose a pump with a timer so you can program it to start heating the water 15 minutes before you usually take your morning shower. That way, you won’t waste energy heating water you’re not going to use, and you’ll still have hot water in an instant when you turn on the faucet.
