Detailed steps to replace solar water heater fluid:
1. When filling water, some wall-mounted solar water heaters drain the water directly without adding medium. In order to prevent freezing, etc., a medium is added to circulate the heat.
2. Leave enough space to inflate/release 500ml after inflation and refill appropriately every two years.
3. Northern antifreeze is an ethylene glycol antifreeze. The heat transfer fluid with freezing point is selected based on different latitudes.
4. The solar media fluid must be replaced every 2 to 3 years to ensure solar energy efficiency. Therefore, when using, we must master the replacement time of ssolar supports. If we can't operate it, we can invite professional companies. They are experienced and can guarantee the effectiveness of solar rack replacement.
Steps to replace the sensor in solar water heater:
1 On the solar water heater, you will find something like a rubber plug. Take something like a rubber stopper and shake it back and forth to remove it. You don't need much force to pull, just shake it gently and you will be able to pull two down. When choosing, pay attention to four or two lines. Then install a solar collector meeting the standard and model.
2. Another way is to remove the previously damaged sensor. You can choose to purchase a set of meters online or in a physical store. There are also sensors and solenoid valves installed inside, which cost around 100yuan. Then insert the newly purchased sensor into the exhaust hole at the top of the water tank so that it can be used again.
