Abstract
The disclosed technology includes a hose nozzle assembly with apertures sized to facilitate heating groundwater based on the expected temperature of the groundwater. The hose nozzle assembly can have a handheld enclosure having a handle portion connected to a body portion, a heating chamber having a heating element configured to heat a fluid, and a spray nozzle. The spray nozzle can include a first aperture configured to provide a first spray pattern at a first flow rate corresponding to a first change in temperature of fluid flowing through the heating chamber and a second aperture configured to provide a second spray pattern at a second flow rate corresponding to a second change in temperature of fluid flowing through the heating chamber. The second flow rate can be less than the first flow rate and the second change in temperature can be greater than the first change in temperature.
