The (pre-set) water temperature is controlled using a thermostat, offering both maximum safety and greater convenience. KWC thermostats prevent any scalding surprises, because, thanks to the hot water pipe being insulated, the body of the faucet becomes no more than warm, providing reliable protection against burning. Thermostats also keep the water constantly at the required temperature and use an intelligent mechanism to compensate for variations in pressure and temperature. KWC thermostats are fitted with a safety stop at 38° C, giving reliable protection against scalding. For higher temperatures, all you have to do is press a button to override the stop.
