1. The speed of heat transmission can be calculated in seconds, that's to say, the start-up of temperature rise is very fast, the heat transmission is 99;
2. The heat output power is three times more than high quality tubes.
3. The tube will not explode, and never have water flow in it.
4. Specially designed for the appropriate environment of solar water heaters, the quantity of heat obtain has improved by 30;
5. No matter in extremely cold or hot weather, it can stand lasting work, no need of cleanout, have no furring forever; Completely put an end to the possibility of the tube becoming the bug seedbed because of furring caused by water flowing in the tube.
