Gas Water Heater
When, in addition to body size, exhaust methods, the thermal efficiency became important to note that a value, if less than 84%, we should beware. In the forthcoming "domestic gas instantaneous water heater limit value of energy efficiency and energy efficiency rating", the clearly defined 84% threshold of the thermal efficiency of gas water heaters, the quality is low,
Energy consumption
Great products will be out of the market.
Learned that the energy efficiency standards have been adopted by the expert ranking of the estimated seven in August this year, can be formally set out.
Question: What is the value of thermal efficiency?
Many consumers might ask: What is the value of thermal efficiency? Consumers with home gas water heater all know, gas water heater is by
LPG
Or natural gas combustion heat to water temperature, the liquefied gas may not burn fully, there will be heat loss, water temperature needed to burn calories and liquefied petroleum gas or natural gas, the ratio between the heat generated is the value of thermal efficiency .
Forthcoming "domestic gas instantaneous water heater limit value of energy efficiency and energy efficiency rating" is the mandatory standard, in its formal implementation, the thermal efficiency is lower than 84% of the gas water heater will be banned from the market
Sell
. The standard to grade the energy efficiency of gas water heater is divided into three classes: the lowest three energy efficiency, thermal efficiency value of not less than 84%; two values of thermal efficiency of not less than 88%; an energy-efficient, thermal efficiency value of not less than 96%. National standard implementation, gas water heater manufacturers must test their products sent to the relevant state departments for testing, obtain a certificate before they can be listed on product sales, substandard products will be mandatory delisting.
Status: fuzzy labeling greater than 80%

Shopping
The sales of gas water heater, whether it had been consistent with the forthcoming national standard then? Yesterday, the reporter visited the mall the gas water heater appliance counters, Panasonic, cherry, forest, million and, Vantage, MACRO and other brands have a gas water heater sales, asked the counter salesperson, but they have a lot of concepts on the thermal efficiency do not know. "What is the value of thermal efficiency? Not very clear." Salespersons are so many answers.
Publicity in the cherry blossoms on a single page of specifications marked thermal efficiency:> 80%, but how it reached the value of the thermal efficiency of how much business there is no clear explanation, just said, "each value of the thermal efficiency of gas water heaters have different. " Macro of the leaflets was not clearly marked out a salesperson to find the test data for a long time to find the results of a sample gas water heater, the basic values of thermal efficiency 84.3% -84.9% in between. Other like Vantage, Matsushita gas water heater, you basically can not find the value of thermal efficiency labeling. "Because authorities did not focus on previously mentioned to mark the value of thermal efficiency, so brands did not pay attention to it." Mall officials said.
Guess: 30% -50% of the brands will be eliminated
"If the value of thermal efficiency according to the old calculation method, 84% is a very high standard, with an estimated number of gas water heaters are eliminated." A water heater manufacturer person in charge said that on gas water heater on the market today, the meet the 84% standard brand and not that much, a large part of the value of the thermal efficiency of gas water heater in 70% -75% of basic between. Related departments predicted that the market is estimated that 30% of the gas water heater face elimination, while the industry is estimated that this figure may be even higher and may reach 50%.
"On energy-efficient gas water heater for the introduction of the mandatory standards, the brand manufacturers, the course is a good thing." Water heater manufacturer person in charge said that at present there are 45 100 domestic gas water heater manufacturers, small businesses low production costs, the price of natural water heater is relatively low. Typically, the price consumers often an important indicator of water heater, if the national standard after the introduction of compulsory out of these brands, gas water heater industry will promote the survival of the fittest. It is understood that, in Australia, Japan, the United States and the European Union and other countries and regions already implemented a mandatory energy efficiency standards for gas water heater.
