    You turn the hot water faucet on and wait. And wait some more. And then after a minute or more, up to four minutes, hot water finally emerges from the faucet. Meanwhile, all that precious water is wasted running down the drain. This process is repeated for countless showers, baths, dishes and other daily tasks all across the country every day. The average household wastes around 40 gallons a day or almost 14,000 gallons of water a year! This waste also results in increased sewerage bills which...MORE are usually based on water consumption.

    If only you had a tankless point of use water heater at every faucet that would provide you with almost instant hot water whenever you wanted. But that's not practical.

    Well, there's a way to get one of the main benefits of a tankless point of use water heater, almost instant hot water out of your faucets for a few hundred bucks.

    How? By using what's called a hot water recirculation pump for demand delivery. This innovative little device allows hot water to be delivered to your faucet without having to wait for the water to run hot while saving water and energy.

    Let's take a look at why you usually have to wait for hot water with a tank type water heater how the hot water recirculation system is your "fast hot water" answer.

    Why You Wait for Hot Water with Tank Type Water Heaters

    With a tank type water heater hot water is sent out from the heater to your faucet or appliance. As the hot water sets in the pipe waiting to be used, it cools off.

    When you turn on the hot water faucet, all the cooled off water has to be displaced with fresh hot water from the water heater. This can be a lot of water volume in the pipes to replace, especially if the faucet is far from the water heater. The fresh hot water also has to warm up the hot water pipes before you get the full...MORE temperature of hot water you want at the faucet or appliance. This can take several minutes, wasting water, energy and time.

    Why a Hot Water Recirculation Pump Ends the Wait

    The recirculation or booster pump is a device that quickly draws hot water from your tank type water heater and replaces the cooled off hot water in your hot water pipes with hot water by sending the cooled off "hot" water back to the water heater via the cold water line where it is heated back up.

    Think of it this way, when you usually let the cooled off hot water run down the drain until it gets hot again, the cooled off water in your hot water pipes has now been replaced with hot water. With...MORE the recirculation pump, the cooled off hot water is just sent back to the water heater (through the cold water line) and very quickly replaced with hot water instead of being dumped down the drain.

    The result is hot water with very little wait time, around 60% to 80% faster than standard water heater configurations.
