Himin Solar is the leader of light and heat in China and even in the world. Therefore, Huangming Solar is the leader in the whole country, and the brand of Four Seasons Muge is also good. But the positioning of this product is still different. Huangming has always been that quality is above everything else, so its positioning is relatively high-end, while the positioning of Four Seasons Muge is relatively low, so quality is the first point. So if you want to buy solar energy, you'd better recommend Huang Ming.
Matters needing attention in using solar water heater:
1. The stored water needs to be discharged regularly: the stored water in the solar water heater needs to be discharged regularly to avoid pollution caused by long-term accumulated water. The discharge cycle is determined by the local water quality, and the discharge can be carried out in the morning because the temperature of the collector there is low.
2. Turn on cold water first and then hot water: If hot water is not turned on on sunny days for several days, the water temperature will be higher. When using, turn on cold water first and then hot water to avoid scalding.
3. Thawing of frozen pipes: The pipes of solar water heaters are often frozen in winter. If the frozen pipeline does not crack, there is no need to worry, and it can work normally when the temperature rises. If it is necessary to thaw the frozen pipeline, never knock on the pipeline, barbecue with fire or use boiling water, or the pipeline will burst. You can wrap the pipe with a towel and pour it slowly with warm water, or blow it with a hair dryer.
4. Clean the vacuum tube regularly: In order to prevent the scale from forming inside the vacuum tube of the solar water heater, it needs to be cleaned regularly, with a cycle of 2 to 3 years.
