Whose water heater is energy efficient and good for use? Introduce, thank you!
shortcomingA one-time high investment: although four years later, the most valuable investment, but people prefer to spend less money early.Low efficiency in cold areas: heat pump water heater can only achieve heating in the climate environment of -10 degrees Celsius, not suitable for northern areas, only for Southern China, central China, Jiangsu and Zhejiang and other southern areas.Instant heating electric water heaterAdvantageThe utility model has the advantages of being capable of opening and heating, saving time and electricity, energy saving, environmental protection, small size, constant water temperature, etc..
Home from the energy point of view, it is possible to force the elimination of electric water heaters, as limiting the use of coal-fired boilers.AdvantageEfficient energy-saving: heat pump water heater to obtain a large amount of heat from the air, making the same amount of hot water, its electricity consumption is 28% of the traditional electric water heater, can save a lot of electricity for users.Safe and reliable: heat pump water heater does not use electricity directly heating, current and shower water completely isolated, is the most safe and reliable hot water supply equipment.All-weather use: heat pump water heater is not affected by overcast, rain, snow and other bad weather, twenty-four hours a day, all-weather use.Durable: heat pump water heater for commercial grade products, high safety, compressor with undervoltage protection, overcurrent, overheating protection, high and low pressure protection, the compressor can work for a long time in the heating mode, the life of the machine for more than ten years.
Air source heat pump water heaterHeat pump water heater has been widely used in foreign countries for more than 30 years, and the proportion used in developed countries is as high as 70%. In Europe and America, the proportion of cold and hot water used is 1:9 (China is 9:1). The cold water in European and American countries is only used for drinking or washing the toilet and washing cars, but hot water is used in other aspects. European and American countries have more than 90% market share of central water heaters (less than 3% in China). These years, Chinese demand for water increases exponentially, the commercial heat pump water heater to replace coal-fired boiler and oil fired boiler has obvious advantages, the general energy efficiency of a year to recover the investment, such as Wuhan has more than 200 hotels, hotels, universities use heat pump hot water unit, which is where the domestic heat pump water heater annual sales growth of three times the reason.Household heat pump water heater due to not let the home appliance stores, promotion is not enough, low market share, according to experts predict that when the price reached 1 yuan / kWh, the country from the perspective of energy conservation may be forced out of the electric water heater, as restrictions on the use of coal-fired boiler.
