§ 66-27.1A.  Water heater thermostat settings. (a) The thermostat of any new residential water heater offered for sale or lease for use in a single-family or multifamily dwelling in the State shall be preset by the manufacturer or installer no higher than approximately 120 degrees Fahrenheit (or 49 degrees Celsius).  A water heater reservoir temperature may be set higher if it is supplying space heaters that require higher temperatures.  For purposes of this section, a water heater shall mean the primary source of hot water for any single-family or multifamily residential dwelling including, but not limited to any solar or other hot water heating systems.

(c) A warning tag or sticker shall be placed on or near the operating thermostat control of any residential water heater.  This tag or sticker shall state that the thermostat settings above the preset temperature may cause severe burns.  This tag or sticker may carry such other appropriate warnings as may be agreed upon by manufacturers, installers, and other interested parties.  (1991, c. 190, s. 1.)
