Who knows the solar water heater vacuum tube has a few? Respectively, single tube heat transfer maximum power is much
If the installation is not restricted, the tube is better than a small tube, long tube shorter than the tube, the reason is very simple,Large tube and long tube heat absorption area, absorb more energy, water fastIf the price is the same, there is a stupid way, you putWeigh one, said the heavier is better
Three cavity tube or pipe in pipe that is not desirable, perhaps you will find that not a famous brand by solar tube, only with Hodge. Why? The water pipe pipe is better than the water temperature of three executives is high, but the same amount of water to boil, he not more than three executives quickly I do not know. This point can make sense? Because of pipe in pipe tube less, absorbs the same quantity of heat, the temperature in the tube is high, but not to burn the same amount of water, and the temperature in the tube more than three executives due to high temperature, easy to scale, a year after the tube needs cleaning possible. Although the major manufacturers have anti fouling measures, but could not get so strict.
Currently on the market of the vacuum tube of Trinidad and Tobago, dazzling. Together with the sales staff that is at a loss, I talk about some personal opinions.Three high pipe: should be the first choice, what is the three high tube? Get hot, high temperature, anti - cold, is the three executives, some manufacturers lumenCopper plating, some manufacturers of aluminum tube, copper to a little expensive, from the economic point of view to recommend the use of aluminum tubes, aluminum tubes under the same conditions may be lower than the copper 1,2 degrees, in order to take the temperature of this twice the price I feel uneconomical
