Himfr Reports Compares Solar Energy, Fuel Gas and Electric Water Heaters
BEIJING, Nov. 5 /Xinhua-PRNewswire/ — Himfr.com ( http://www.himfr.com/hot-products/ ), one of China’s leading B2B search platforms with more than 30 B2B industry websites to its name, has learned that consumers often have trouble choosing a suitable water heater ( http://www.cheaponsale.com/buy-water_heater/ ). Should they choose one powered by electricity, gas, or solar energy?
Water heater is divided into three main categories.
Water heaters on the market today can generally be divided into three main categories: fuel gas water heaters, electric water heaters ( http://www.himfr.com/buy-electric_water_heater/ ) and solar water heaters ( http://www.himfr.com/buy-Solar_Water_Heater/ ). Famous brands of electric water heaters are Ariston, Smith, Haier, Midea, Biliqi, Shuai Kang, and others. The Solar water heater industry is new and has few well-known brands yet; they are Huang Ming and Tsinghua Solar. Due to early widespread adoption, fuel gas water heaters had the largest market share and will maintain a strong position in the near term, but currently the largest share is held by electric water heaters, accounting for about 70% of the market. In this field, Haier, in a joint project with the Chinese Academy of Sciences, developed the use of 3D dynamic heating technology in water heaters, giving Haier a leading position among its competitors.
Comparing the three categories of water heaters by their functions
First, the volume of hot water produced. Generally, fuel gas water heaters ( http://www.cheaponsale.com/buy-gas_water_heater/ ) have 5 liter, 7 liter and 8 liter capacities. Within 1 minute, the water temperature in their tanks can rise by 25 degrees Celsius. If the water temperature is 25 degrees Celsius, the per-minute production can be 5 liters, 7 liters or 8 liters of 50 degrees Celsius water. Electric water heaters are generally marked as 30 liters to 90 liters. This number refers to the capacity of the water. Electric water heaters act just like an electric-kettle ( http://www.cheaponsale.com/buy- electric_kettl/ ). In this case, the kettle capacity is 30 liters to 60 liters. An 8 liter fuel gas water heater can continuously produce 8 liters of hot water per minute, while electric water heaters need half-hour intervals to heating an entire tank full of water. If you do not control the time taken in the bath/shower, then the water will eventually run out and you will have to wait for half an hour or so before it can resume.
Solar water heaters, based on the average annual temperature of 15.7 degrees Celsius, receive an average of 2014 hours of annual sunshine. This translates into an average annual throughput of 111.59 therm / m2 of solar radiation. For example, in an area of 2 square meters of solar panels, the annual absorption of solar radiation energy to 9.37 ÃƒÆ’Ã‚“šÃƒ“šÃ‚¡ÃƒÆ’Ã‚Æ’Ãƒ“šÃ‚Â 106 kJ. At this rate, a water heater can raise water temperatures by 35 degrees Celsius, providing a full year of hot water (45 degrees Celsius), or about 53.5 tons. If each person taking a bath with hot water uses about 50 kg of water, this works out to 1070 people being washed per year, or a daily average of 2.93 people.
Second, comparing heating rates
At present, the production rates of fuel gas water heaters make them the fastest water heaters. No matter what, as soon as you open the gas valve and the hot water faucet, the heated water can be used immediately. Electric water heaters ( http://www.cheaponsale.com/buy- Electrical_Water_Heater_(Shower_Model)/ ), however, need to electrify and can take up to a half an hour or so before the water is ready to use. Solar water heaters, when using them on a clear day, are much better; the best models can heat their water in six to eight minutes.
Third, temperature stability
Fuel gas water heaters use rapid heating and temperature adjustment devices, so as long as the people using the water are comfortable with the temperature (usually 40 degrees Celsius – - 50 degrees Celsius, but this can vary from person to person), it is simple to keep it constant. Electric water heaters raise the temperature of the entire can of water, and when water is used it’s temperature is higher (usually around 80 degrees Celsius), resulting in a need to add cold water to adjust the temperature. So during usage there is a constant need to adjust the ratio of cold and hot water. Solar water heaters’ ( http://www.himfr.com/buy-heat_pipe_solar_water_heater/ ) use is not very convenient in this area, as there is a constant need to pump water and there is no guarantee that a supply of hot water will always be available.
Fourth, the price
From the purchase and installation, and other one-time investments, an 8 liter fuel gas water heater is generally more than 800 yuan, and with installation fees can be more than 1,000-2,000 yuan. Electric water heaters usually cost more than 500 yuan, and with installation costs, are generally less than 1,000 yuan, though some models can reach the 1,000 yuan level. Prices of solar water heaters are more than 3,000 yuan.
In a short, when you want to buy water heater, there are many factors to consider. To help you to choose a suitable fuel gas, solar or electric water heater you can you can login to our website http://www.cheaponsale.com/ to see s reference guide.
