The standard for energy efficiency of water or will compete

Although the hot product integration trend is becoming the development trend of the industry,but in the majority of consumers in the family, is still only choose one or two kinds of water heater products. In the selection process of such products, energy efficiency has become the focus of attention. But before doing homework consumers often confused: the same 1 energy-efficientproducts, the efficiency of what's the difference? Recently, industry sources said, the water heater in different types or will compete. "It is said that solar water heater is energy-saving products, but the electric auxiliary heating function using the product efficiency and electric water heaters and gas water heater is high compared to who?" Liu consumers put forward their own questions.Since October 1st this year, the air is hot water began to implement energy efficiency standards.Since then, four kinds of water heater's energy efficiency have a standard to follow. But the reporter learned that, not only the energy efficiency rating methods of different types of products of different grades, the number of the final differences.As July 1, 2007 began the implementation of the gas water heater energy efficiency standardsfor gas water heater energy efficiency rating is divided into 3 levels, including 1 represents the highest efficiency, thermal efficiency of the value of not less than 96%, 2 level of not less than 88%, 3 level of not less than 84%, less than 84% of the gas water heater will not be able to continue to sell."Storage type electric water heater energy efficiency limit value and energy efficiency rating"from November 1, 2008 formally implemented, the standards for the evaluation of energy efficiency grade products are divided into 5 levels, the 1 level is the highest level of energy efficiency. Energy efficiency is less than 5 of the products are not allowed to sell in the market.August 1, 2012 started the implementation of the "domestic solar hot water system energy efficiency limit value and energy efficiency rating" is the solar water heater industry the firstmandatory national standards, the domestic solar hot water system energy efficiency is divided into 3 grades.Air to water heater's energy efficiency standards -- "heat pump water heater (for) the allowable value of energy efficiency and energy efficiency rating" was formally implemented in October 1st this year. This standard specifies the type of energy efficiency products are divided into 5grades, 1 levels of representation of the highest energy efficiency. The minimum allowable values of energy efficiency and energy efficiency grades shall be not less than 5 of the value ofthe coefficient of performance of heat pump water heater measured value, evaluation of energy saving hot water heat pump energy efficiency rating value should be the provisions of 2 values."Whether it is a gas or electric water heater, or the air to water heater, as a consumer, may bedifficult to determine what kind of product is the most energy-efficient, after all, the evaluation system is fragmented." International Copper Association relevant responsible person said, at present, it is with all of the water heater energy efficiency standards for various types ofdischarge in the same system are compared, but the research has not yet entered a substantive stage of operation. The person in charge of China standardization institute a also said, do have the intention, but specifically what time to start this work is open to question.However, experts also said, once more on the same platform, the ranking is probably the electric water heater, it should be said to be the largest energy consumption. Although in 2005 the EUissued a requirement of ecological energy saving product design (the EuP directive), and from this year the electric water heater in the EU market has basically been eliminated, but China'selectric water heater market share is still relatively high. Zhongguancun Zaixian released 2013April "China water heater market analysis report" shows, China water heater market, electric water heater is still the mainstream products in the market, the interest rate is close to two times of the gas water heater products. Among them, concerned about the ratio of the electric water heater products was 65%, and the gas water heater on the proportion was only 35%.A year ago, China household electrical appliances technology conference, China Household Electrical Appliances Association published "China's domestic water heater industry technology roadmap" (2012 edition). This is the first technology roadmap of household water heater,planned for 2012 to 2020 years of electric water heater, heat pump water heater and solar water heater industry technology. The roadmap that, energy saving and emission reduction of household water heater industry has two major directions: one is to improve the energy efficiency of electric water heater; the two is to promote the heat pump water heater, solar water heater and a combination of energy products such as renewable energy, new energy product development, product specification and upgrade.
