But it costs higher. 3) Ceramic shell, it’s good in resistance to corrosion. But its heating power could not be very large. 4) Stainless steel or titanium shell or pipe, it is very excellence for preventing corrosion, and meets food safe standard. But it costs higher and has bigger bulk. China patent number: ZL 2011 2022 0811.4, ZL 2011 2022 0805.9.5) Anti-corrosion coated aluminum shell, it is corrosion resistance, and prevent incrustant, but the cost is quite high.2. Some samples of uses.PTC water heater could be used for shower, footbath, washing hand, vegetable and dish, drink warmer and boiler, fermenter, tea warmer, coffee warmer, milk warmer, vapor generator, sauna bath.They could be used in heating diesel oil, gasoline or other liquid. Using PTC as a heating element could prevent the oil burning, it’s safer.3. Notice in appliance.PTC as a heating element, it fits for high safety, slap-up product. In some situations, it’s low cost and convenient.The electric power of PTC water heater changes with the temperature of water. The higher is the temperature of water, the smaller is the power. Using higher switch temperature PTC can get higher power, 220~270℃switch temperature PTC is selected usually. But if select too high switch temperature, the reliable will reduce. Power is almost same to change the voltage twice or decrease of 1/2. 4.
