How water re-circulating pumps work

In homes that do not have a recirculation pumps it may take several seconds to get hot water but with a recirculating pump you constantly get hot water. This is made possible by a loop in the system. Buildings like hotels, hospitals and commercial office buildings use recirc pumps. If you want to replace your current pump with a recirculating pump it isn?t that hard to do.

A plumber would have to come and install water supply lines to each fixture in your home. Then the plumber would have to install a ? inch diameter heater that goes into all of the fixtures in the home that need hot water. Then he will install a ? inch pipe that would extend throughout the home and then branch it off to feed hot water. Then the line would continue to go back to the water heater without any breaks in the pipe. This return pipe would connect to the bottom of the water heater where the drain valve is located.

All you need to make the loop work is the ? inch supply line has to be insulated when it leaves the water heater and goes towards each faucet that gets hot. The return loop has to be insulated after it passes the last faucet and is heading back to the heater. The last 15 feet of pipe, leave uninsulated, the pipe has to cool. The reason why the water stays so hot throughout the system is because the water works its way slowly by gravity and it lets the water in the system to stay hot.

By having a recirculating system it allows you to save money on your energy bill, because you won?t need to run the water for a long time in order to get the faucet water hot. You won?t be wasting so much water either. It may cost you a bit of money to get this recirculation system but it will be well worth it in the end. You will get hot water whenever you want by simply turning on your faucet and you will save money on your water bill as well as your water bill.
