I occasionally manage to leave my garden hose in the yard rather than rewinding it back into its reel box. Although it is not boiling it IS painfully hot so I sometimes spray the hot water on places I want to kill weeds (the edge of the lawn where it comes to the raised beds is one of my favorites lately). I have to pay attention to the temperature of the water so I can't get a big area, but it's a nice use for the built up heat and something "to do" while waiting for the water to cool down. My problem is remembering to do that instead of just aiming the nozzle into the air to let the water cool as it falls to the ground.
