Water Heater Aluminium Shell T Shape Tube PTC Heater for Foot Bath Tub Sprayer
1. Configuration.
| Type | Specialty | Excellence | shortcoming | Others |
| Transflux heater | Water transflux hole of the heater | Large power, quick heating | Water must flow by itself or by a pump. | Water can be heated in tap water supply |
| Immerging heater |
Heater immerge at bottom of water tank | Heat quiet water, with uniform temperature | Rising time is too long to heat the water in whole tank | Fit for large power |
| Underside heater | Heater is placed underside the tank | Heat quiet water, with uniform temperature | Rising time is too long to heat the water in whole tank | Fit to maintain temperature of water |
| Double insulators heater | With two layers insulators and two metal shells | Top safety | Higher cost | No electric leakage on surface when PTC was burn |
| periphery of pipe heater | Around the periphery of metal pipe | The heater can contact the pipe very fit | The power can not be large; energy can not be used very effectively | Suitable for the situation the pipe can not be changed |
| Temperature control water heater | With a temperature controller, the temperature of the water can be adjusted | The temperature of water Can be controlled with accuracy of 4℃ | Larger volume of the system, more cost. | Suitable for the situation necessary to control the temperature of water |
Various materials.
1) Aluminium shell or pipe, it is not good in resistance to corrosion. Nickel plating or anti-corrosion coating could be better in preventing corrosion.
2) Brass or copper shell or pipe, it is good in resistance to corrosion. 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 shell or pipe, it’s very excellence for preventing corrosion, and meets food safe standard. But it costs higher and has bigger bulk.. China patent number:
5) Anti-corrosion coated aluminum shell, it's corrosion resistance, 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 wamer, 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.
