Rapid heating Electric water heater What is the energy consumption level based on? There are two performance indexes for evaluating the energy efficiency grade of electric water heater: hot water output rate and 24-hour inherent energy consumption coefficient.
Hot water output rate: the electric water heater is heated to the rated high temperature, and then the hot water inside is discharged. The volume of hot water discharged when the tank temperature is 20 degrees lower than the high rated temperature is the ratio of the rated volume of the water heater to the hot water output rate of the electric water heater. The higher the hot water yield is, the higher the efficiency of the electric water heater is, and the more energy-saving it is.
Due to quick heating Intelligent thermostatic water heater The vertical water tank is used (i.e. placed vertically), so the hot water output rate is superior to the traditional electric water heater with horizontal water tank.
24 hour intrinsic energy consumption coefficient: refers to the ratio between the actual energy required to maintain the water temperature at the set temperature and the standard limited energy without using the water heater. The lower the ratio, the better the thermal insulation effect of the water heater. Generally ε express. Level 1 energy efficiency correspondence ε≤ 0.6, corresponding to level 2 energy efficiency ε≤ 0.7, Level 3 energy efficiency correspondence ε≤ 0.8, corresponding to level 4 energy efficiency ε≤ 0.9, corresponding to level 5 energy efficiency ε≤ 1.0。
This is often the reason why the energy efficiency level of the fast heating intelligent constant temperature water heater is higher than that of the traditional electric water heater. It can be seen from the above analysis that the 24-hour inherent energy consumption coefficient is an indicator reflecting the thermal insulation effect of the water heater. The better the thermal insulation effect, the lower the energy efficiency level (Level 1 is good). The fast heating intelligent constant temperature water heater is generally designed to be light and thin, so the insulation effect is certainly not comparable to the traditional water storage electric water heater.
1. Choose high-quality and reputable electric water heaters.
2. Unplug the power supply when the water heater is not in use.
3. The shower temperature is generally set at 40 to 50 degrees Celsius, and too high water temperature is also bad for human skin.
4. In summer, the temperature controller can be lowered, and the cost can be reduced by replacing bath with shower.
5. For the case that it has been used all the time (usually used by commercial users such as hair salons), it can only be maintained Instant electric water heater Normally open, but the temperature of hot water can also be properly adjusted according to the number of guests. So as to save electricity cost.
6. In the case of frequent use (generally, the kitchen and bathroom use one water heater at the same time, and hot water is used for cooking, washing dishes, and bathing), we recommend that the water heater be kept on all the time. The temperature of hot water can be adjusted according to the frequency of use and the amount of hot water used. If the amount of hot water used is small, the temperature can be lowered a bit, and if the amount of hot water used is large, it can be raised a bit.
