The key is that the entire heating surface of the water heater should face south, and there is one thing that is not strictly implemented by all water heater companies on time current, namely the angle between the entire solar panel. The water heater and floor should be consistent with the local latitude, to ensure maximum heat absorption efficiency. However, in fact, the angle between all water heaters and the floor is greater than 30 degrees, or even around 45 degrees. In fact, China's latitude is not that high at all.
Why is it designed like this? I asked the seller and they couldn't answer. Their designers don't know who taught them. Anyway, that's what I was asked to do when I was studying solar energy.
There is a drain hole on the top side of the SunRain Solar, an overflow outlet at the water inlet below and an idle hole. WhatWhere is this idle hole for? Can it be blocked?
Approximately 30 centimeters.
Replace the solar water heater probe, remove the original probe and cut the signal wire connector. Install the new probe, then connect the signal cable, and that's it. It is recommended to seek after-sales service at the place where you purchased the solar power rather than repairing it yourself.
Solar instrument sensor, commonly known as solar probe or instrument probe function, uses the principle of electronic induction to measure the water level and temperature in the water tank solar and displays them on the solar instrument.
Make sure that the internal structure of this free hole is the same as that of the overflow hole, and it has no other purpose, then it can be blocked and not used.
However, in addition to the exhaust hole, overflow port and water inlet and outlet,The hot water storage tank of the solar water heater should also have a port for the hot water temperature sensor. It is recommended to find out where the hot water temperature sensor is located.
If it turns out to be unnecessary, it can be blocked. When blocking, a plug should be added to the lower part of the metal liner of the water tank, not just the outer shell or insulation layer of the water tank.
