Brilliant solar energy who have used in the end is not good to use

Having not used the brilliant, my family used the Sang Le's, on the first year is very good to use, and will not be bad. From the second year onwards, the small problems constantly, either this pipe is broken or that pipe cracked, every year to spend a few hundred dollars. At that time, when I bought the solar energy spent 3300 yuan, might as well buy a water heater less than 2000 yuan, can be used for many years without problems. In the winter solar energy to open the anti-freeze device, about 3 degrees of power consumption per day, which is also an expense. In short, solar energy is a consumable product, can not buy. Three days out of trouble, every time to repair hundreds or even hundreds of dollars. If you are in a position to do so, you should buy a gas water heater.
