Sl. Webne et Bj. Kaplan, PREVENTING TAP WATER SCALDS - DO CONSUMERS CHANGE THEIR PRESET THERMOSTATS, American journal of public health, 83(10), 1993, pp. 1469-1470
One goal of the regulatory approach to tap water scald prevention is t
he installation of hot water heaters at thermostat settings considered
safe. In this strategy, it is assumed that consumers will not change
preset thermostat settings, an assumption evaluated in a study of 62 f
amilies. It was found that 60% of the sample did not change their pres
et thermostats. Surprisingly, some of those families (27%) who did not
increase their settings still had unsafe (>54-degrees-C) water temper
atures.
