Spring Most Distinguished AAA cree flashlight Let's share the experienced sayings of the netizens. Electric water heaters, according to different heating principles, are divided into the thermal heating andthermal storage. Other more new electric water heaters are accepted by consumers as well.
Regarding the new types, the most representative energy-saving products are instantaneous electric water heater and heat pump water heater. Heat of air-source heat pump water mainly comes from the air, under ambient temperature of 20 ℃, the average EER of heating a can of water (150L) can be 3.2 or above, that is, heating efficiency is equivalent to 3.2 times the average electric water heater, thus the energy-saving effect is very conspicuous. It means that the effect of the heat has no loss without insulation, energy can be used better with sound science, it is the rapid rise as for popularity in the electric water heater products.
But under normal circumstances, it is recommended that users use ordinary volume-type water heaters. As for the hot-type electric water heaters, it is recommended that only families with large power meters can consider using this product and air-source heat pump can be considered as to the larger villa type chamber. Hence, considering the limit to the environment and level of technology, this book mainly introduces water-storing type product or capacity-type product. It is also suggested the majority of families should first consider heat-storing electric water heater with a long history and stable technologies.
The capacity of storage-type electric water heater ranges from 5L to 3000L, including different categories. The manufacturing technology has totally matured and different technical functions can meet customers' requirements. Generally speaking, a small water heater with a volume around 10L is mainly used for dish-washing and hand-washing in kitchens and bathrooms; while water heaters with a volume from 40L to 80L are primarily used for bathing by general low-income families. A capacious electric water heater of more than 100L is mainly used for those users who live in villa or have many bathrooms in dual structure.
The ways of temperature controlling can be divided into mechanical way and computerized way. The main features of mechanical electric water heater, controlled by thermostat include constant adjustment of temperature within limited areas, simple operation, good reliability and low price which fit for use by average families. The deficiency is that the temperature is regulated in a simple way with only circular heating method available. The computer board falls into digital display and numerical control. If users pursue one-stop, we suggest choosing products of digital display type.
LCD display screen on the NS display panel is used to display the operating modes, heating condition, the current temperature and to set temperature, menu, clock, time period, and fault codes, etc, by using the on-board buttons. From the second half of 2007, you can benefit from the release of new national standard about water heaters. By only looking at the product plate on the heater, you can recognize the quality condition. Because new national standards through key indicators of products to classify and reflect the differences in product qualities. The most important one is those specific requirements on energy-saving and durability.
After obtaining relative lever certification, enterprises could show to consumers with the grade plate on terminal markets and use the certification as a foundation to recommend products of high quality to consumers. According to product performance as required, Electric water heater is classified in grades as A, B, C, D, E. Grade A stands for the top quality, with grade E at the lowest. When choosing a product, people can tell the quality of each product only through the nameplate on each product.
