A hot water recirculation system 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 hot water arrives at your faucet or shower (when the cooled off water in your hot water pipes has now been replaced with hot water). With a hot water recirculation system, 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.
New eco-friendly innovative and patented technology known as the Hot Water Lobster Instant Hot Water Valve makes installing a hot water recirculation system a breeze. It uses your existing water pipes and the thermal convection generated by your water heater to circulate the water back to your water heater for reheating (not requiring a pump or any electricity). To save water and save energy, these systems have a temperature-controlled valve that allows the consumer to easily adjust the temperature to meet their particular needs. There is no water waste as it reduces the energy required to heat your water while it provides faster hot water to all of your faucets and showers for better water conservation. Installation is a simple DIY project (no pipe cutting, soldering or electrical connections).
