Which is better, timely glass heating pipe or ptc heating pipe?

Of course PTC ceramic heater is better. The quartz tube is easy to burst, resulting in electric leakage. Now it's basically eliminated. PTC heater is incomparable with other heaters. PTC heater has high insulation, safety and high heat energy conversion rate. They also have a constant temperature function and will not be burned because of the failure of the overheating protector. This is not available in other heaters. The most unsafe are quartz tubes and electric heating wire heaters.
