Solar water heater energy efficiency rating and marking system to promote the development of industry standards

Under the background of the increasingly severe global energy crisis, solar energy has been widely used as a new energy source. China also actively promotes the application of solar energy, and now solar water heaters have also entered millions of households and become a daily necessities for people. However, in the solar water heater industry, the quality of products is uneven, and the industry's low threshold leads to low technical levels and people are worried.

In order to ensure the healthy and orderly development of the solar water heater industry, China's first mandatory national standard for the solar water heater industry - "Limited value and energy efficiency rating for domestic solar hot water systems" has been publicized. This means that China's solar water heaters will have to implement energy efficiency levels and marking systems in the future, and the industry has a unified standard.

It is reported that after the completion of publicity, the “Energy Efficiency Limits and Energy Efficiency Ratings for Domestic Solar Hot Water Systems” is expected to be officially implemented around the National Day, and energy efficiency signs are also expected to be announced at the end of the year. The standard divides the energy efficiency of solar water heaters into three levels, of which level 3 is the market access threshold and level 1 represents the highest energy efficiency. In the future, China's solar water heater related companies will be based on the industry standards for production and sales. Solar water heaters will become more and more standardized, and ordinary people will feel more comfortable with them.
