Hello, why is the water in my flat solar panel not heating after filling it with engine antifreeze?

First of all, you need to analyze and understand whether the water itself is not hot or the water you turn off is not hot. The reason the water itself is not hot is usually because you keep adding water or the vacuum tube. cannot absorb heat. What you turn off is not hot. In addition to the two reasons above, another common reason the water isn't hot is that your valve is broken. After turning on the water, do so. do not use it for a day. Be careful that there is water dripping on the roof. If there is, just continue adding water, otherwise, open the sewer pipe. If the water is hot, it means your mixer is. broken. If the water is not hot, simply replace the suction hose.
