Autocirc Hot Water Recirculation Pumps
These pumps use the existing cold water line for circulating water back to the water heater

How do these recirculation pumps work?
The hot water line in your home carries hot water from your water heater to the different sinks, baths, and showers in your home. If you turn on your hot water faucet in your house without a recirculation system, all the water sitting in the water line has to pass through the pipes before the hot water from your water heater will reach your faucet. The result is gallons of water wasted while waiting for hot water to arrive.

A hot water recirculation system runs a return line from the end of your last faucet back to the water heater. Instead of wasting hot water sitting in the pipes, it's circulated back to the water heater and reheated. As a result, you get hot water very soon after turning on your faucet!
Main features and benefits for these hot water recirculation pumps:
  • Gives you hot water instantly whenever you turn on your faucet, shower, or tub - no more waiting for hot water
  • A recirculating hot water system saves the average family of four up to 17,000 gallons of water a year - great for the environment and your water/sewage bill
  • 24 hour timer included - allows you to run the recirculation pump according to your schedule
  • Thermostat included - the pump will only operate when needed
  • The Autocirc® recirculation system is designed to be installed in a finished house using the cold water line as the return line, so you don't have to pay the high costs of installing a dedicated return line as with conventional recirculation systems

frequently asked questions about Laing Recirculation Pumps

information about Laing Recirculation Pumps"How do I know when a recirculation pump would benefit my home?"
education and frequently asked questions about Laing Recirculation PumpsIf you have to wait 30 seconds or more for hot water to arrive at your faucet/shower that's farthest away from your water heater then a recirculation pump could be a great benefit.

information about Laing Recirculation Pumps"How do I know what size pump I need for my recirculation system?"
education and frequently asked questions about Laing Recirculation PumpsIf the total length of the hot water supply line plus the length of the return line is less than 250 feet then a pump with 33 watts or less is recommended (about 90% of people fall under this category). If it's more than 250 feet then you should look at one of the bigger models. However, if you have a tankless water heater, then the UCT-909 tankless water heater pump is your best option when selecting one of these recirculating hot water pumps.
