To the winter, how to use or maintenance to make solar water heater life.Winter solar water heaters are rarely used, may be the cause of the environment, the water heater is not very hot, I worry about the pipeline would be frozen. How to do it.Some people say that the water in winter to vent, so good?
The residual water in the pipeline pumping back to water tank, so every time when the water is hot water, cold water is not discharged, saving water and avoid water pipes frozen in winter.
First, if the winter is no longer using solar water heaters, solar energy can be used up or emptied of water, the pipe is empty, it will not freeze.
To the winter, how to use or maintenance to make solar water heater life. This question is often asked, I simply say a few points, may be able to help busy.First of all: solar vacuum tube is generally difficult to freeze, mainly due to the vacuum tube is made of high boron silicon. The mechanical strength is relatively large, but also absorbs part of the heat, there is no need to do this in the vacuum tube, in winter, even worried that we are incapable of action, remove the vacuum tube is very troublesome, but also worried about the damage of silicon rubber ring. So, we don't have to go to the vacuum tube. So far, we have not heard about the vacuum tube cracking reports.
Two, there is a simple and practical. The long-term use of the method, you can add a small solar water tank outlet pumping device, when no water
