The solar water heater is an energy-saving and environmentally friendly water heater that can make full use of solar energy for heating, heating and water supply. However, during use, due to the large amount of impurities and salts contained in water, scale will form over time. Scale will reduce the heat conduction efficiency of the water heater, leading to heat loss, pressure reduction and other problems. If it is not cleaned in time, it will affect the life of the solar water heater.
So how do you descale solar water heaters?
Method 1. Cleaning with acetic acid
Acetic acid has a good cleaning effect and can effectively remove scale in water. The method is to mix acetic acid and clean water in a ratio of 1:1, then pour the mixed liquid into the solar water heater, let it sit for 30 minutess after filling, then drain the mixed liquid and clean it.
Method 2: Cleaning with citric acid
Citric acid contains strong acidity and has a strong ability to react with scale and can completely remove scale. Mix citric acid and water in a ratio of 1:10, pour the mixture into the solar water heater, let it react naturally for 5-10 minutes, then rinse it with clean water.
Method 3: Cleaning with Oxalic Acid
Oxalic acid is very effective in cleaning scale, but oxalic acid is corrosive, so you need to be careful when cleaning use it. Mix oxalic acid and clean water in a ratio of 1:10, pour the mixture into the solar water heater, let it react naturally for 5-10 minutes, then rinse it with clean water.
Method 4. Machine cleaning
If the above methods cannot meet the cleaning requirements, you canbe sure to use professional cleaning equipment for cleaning. These devices use high pressure water flow and cleaning products to completely remove scale from solar water heaters.
In short, cleaning the scale from the solar water heater is a necessary task to ensure its normal use and extend its lifespan. In order to prevent tartar from forming, we need to drink more pure water and avoid using water that contains a large amount of impurities and salts.
