Ptc Water Heater By Radiant Energy Technologies

Transflux type. Water flows in the hole of the heating element and the water could be heated by the heating element.
2) Immerging type. The heating element is immerged in a water container, and the water could be heated by the heating element.
3) Underside type. The heating element can be put under a water container, and the water could be heated by the heating element.
4) Surrounding pipe type. The heating element can be surrounded out of the metal water pipe and the water in pipe could be heated.
The above types can be consist of materials below:
1) Aluminium shell or pipe, it is not good in resistance to corrosion. Anti-corrosion coating could be betterin resistance to 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.
5) Titanium shell, it's very good in corrosion resistance, but the cost is quite high.
