PTC Water Heater, the heater into the liquid container to heat, the liquid to obtain a constant temperature. With PTC components as a heat source, with a heating rate, temperature heating, power self-regulation, high heat conversion.
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) Anti-corrosion coated aluminum shell, it's corrosion resistance, but the cost is quite high.
