PTC Water Heater are divided into the instant liquid heaters and the storage liquid heaters.
Because the PTC heater behaves well on the insulation,service life,dry heating,especially self-regulating and constant heating. PTC Liquid Heater,it is really the good option for a safe appliances.
PTC heater can heat in constant temperature ,so there is a maximum self-heating temperature(the Curie temperature).It can prevent the damage to the other components surrounding.When dry-heating in the air,the PTC heater would not be damaged by itself. e.g. when the fan stalling or water breaking off.
Reliable performance,long service life,never overheat
PTC heater can work well in wide voltage range.When its operating voltage is two times the nominal voltage,the surface temperature changes very little.But for the sake of the longer service life,it is better to use in Â± 15% the nominal voltage
When multiple PTC heaters are used together, should connection in parallel, shouldn't connect in series.
