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.
