Abstract
Improvements in a hot water circulator are disclosed. The hot water circulator is placed in proximity to one or more water faucets or tubs. The construction of the hot water circulator creates a venture in the cold water line. When a user turns on the cold water the flow of cold water through the cold water line draws a portion of water from the water heater through the hot water line and into the cold water line. Because only a small portion of water is being drawn into the cold water line the temperature difference is negligible, but the hot water is brought to close proximity to the hot water valve where it is more quickly available. There is a reduced amount of water being wasted to bring hot water to the hot water valve. Hot water is delivered in seconds rather than minutes.
Claims20
A multi-stage hot water recirculator comprising:
- one of a three stages of a water recirculator is a shut-off valve;
- one of three stages of said water recirculator is a pressure regulator valve;
- one of three stages of said water recirculator is a swing valve or spring valve;
- said three stages are arranged in a serial arrangement;
- a water return line connected from a water supply valve to said three stage water recirculator to a location in close proximity to where a cold water supply is connected into a hot water heater, whereby
- when water is flowing through a cold water pipe supplying water to said cold water supply, some water is drawn from a hot water supply pipe to said water return line.
A hot water recirculator comprising:
- a through pipe with an inlet and an outlet;
- said through pipe further having a side port wherein said side port enters into said through pipe at an angle;
- said side port extends into and terminates within said through pipe whereby,
- when water flows from said inlet to said outlet water is drawn through said side port and out said outlet;
- a water return line connected from a water supply to said side port to a location in close proximity to where a cold water supply is connected into a hot water heater, whereby
- when water is flowing through a cold water pipe supplying water to said water supply valve, some water is drawn from a hot water supply pipe to said water return line.
A hot water recirculator comprising:
- a through pipe with an inlet and an outlet;
- said through pipe further having a side port wherein said side port enters into said through pipe with at an angle;
- said side port terminates within said through pipe whereby,
- when water flows from said inlet to said outlet water is drawn through said side port and out said outlet;
- connecting said inlet to a cold water supply in placed in proximity to a hot and cold water dispensing location;
- connecting said outlet to a valve to said water dispensing location;
- connecting said side port to said hot water supply of said dispensing location;
- whereby when water is flowing through from said inlet to said outlet some water is drawn from a hot water supply pipe to said water return line.
