Abstract
A joint connects to a hot water source, a toilet tank of a toilet, and a hot water outlet. A set of pipes connecting the hot water source and the joint may be referred to herein as “main hot water pipes.” Water exiting the hot water source into the main hot water pipes is above a desired water temperature. As time passes, however, water that rests in the main hot water pipes may fall below the desired water temperature. Rather than wasting all of the cooled water resting in the main hot water pipes in order to use hot water at the hot water outlet, at least a portion of the cooled water may be used to refill the toilet tank. Therefore less cooled water exits the hot water outlet before fresh water reaches the hot water outlet.
Claims20
A system, including:
- a hot water source;
- a toilet tank of a toilet, wherein the toilet tank is configured to hold water for flushing the toilet;
- a hot water outlet;
- a joint, directly or indirectly, connected to at least (a) the hot water source, (b) the toilet tank, and (c) the hot water outlet;
- wherein the joint is configured to pass water from the hot water source towards at least the toilet tank and the hot water outlet.
A toilet, including:
- a toilet tank, wherein the toilet tank is configured to hold water for flushing the toilet;
- a valve, directly or indirectly, connected to (a) the toilet tank, (b) a hot water source, and (c) a cold water source;
- wherein the valve is configured to control at least one of a first level of water flowing towards the toilet tank from the hot water source and a second level of water flowing towards the toilet tank from the cold water source.
A method, including:
- passing, through a joint, a first volume of water from a hot water source towards a toilet tank of a toilet, wherein the toilet tank is configured to hold water for flushing the toilet;
- passing, through the joint, a second volume of water from the hot water source towards a hot water outlet.
