Abstract: A water heating and distributing system for affording freeze protection to plants and trees characterized by its utilization of a helical conduit for transporting the water to be heated in close proximity to a burner whereby the water's temperature is raised about 20.degree.-25.degree. F. The system further includes a plurality of jet spray heads disposed downstream of the heater in close proximity to the plants and trees to be protected, whereby a relatively fine mist, or fog, of heated water is applied for freeze protection.
