with different regions
China has a vast, different regions of the s use a different installation requirements.
First, Jiangsu and Zhejiang
Jiangsu and Zhejiang area residents have the habit of bathing every day, require 24-hour hot water supply, and demand is larger. These areas generally rainy, to use hot water, first choose a large-capacity water heaters, water heaters, the use of high-quality insulation, with the first day of the rest of the hot water will need to maintain a few rainy days; the second is to increase the auxiliary heat source or Accessibility of solar water heaters electricity, less use of electricity in the circumstances, it can easily achieve all-weather hot water supply.
Second, the high-latitude region in Northeast
Northeast weather is cold, you can use a single vacuum tube water ratio lower products, such as choice of 2 m long vacuum tube 1, and a smaller water tank (inner diameter smaller) water heater, now there is a close-packed s are also suitable, use antifreeze-type 50-degree angle to the best solar water heater. Liaoning and southern Jilin must be on the water pipeline and water tank insulation layer on the use of thicker insulation material. Heilongjiang alpine region must multiply the area of ??household lighting, the upper and lower water pipe must be vented to prevent cracking pipes. Also, you can take heat cold (heating cable) measures, keeping in mind the temperature limit to prevent burn pipeline.
Third, Qinghai, Tibet, Xinjiang, Northwest
Northwest sunshine for a long time, intensity, and the temperature difference between day and night, conventional energy is not well-off, is the development and utilization of solar energy gold regions. There are experts from the sun, \"recent\" Qinghai-Tibet Plateau, the average annual sunshine radiation reached a total of 6000 ~ 8000 MJ per square meter, the annual period of up to 3400 hours of sunshine. Especially the western region of Tibet, solar radiation after the Sahara Desert, ranking second in the world. Although these areas, winter cold, but very good day sunshine, hot water temperature remains high, to meet people\\ s hot water needs. However, due to the larger sand, water heaters, wind resistance must be very strong.
Fourth, the Ningxia region
Ningxia region is temperate continental semi-arid climate, cold winter and hot in summer temperatures greater temperature difference. Long hours of sunshine, high strength, very rich solar energy resources. Although living standards are not high, but because of the unique geographical conditions, the solar water heaters are increasingly welcomed by the local people. Also located in the northwest gateway to the region, the solar business flow more developed, but to the local consumption of solar water heaters.
Five areas of Fujian and Guangdong
Low-latitude region of Fujian and Guangdong, is a subtropical region. Hot weather, water heater pipe insulation need not cost the same price you can buy a larger lighting area and tank capacity of solar water heaters. Although the alternating rainy but frequently confront, does not affect performance, high-capacity solar water heater provide enough hot water every day. But the best use of auxiliary heat source to meet the longer rainy weather.
Sixth, Yunnan and Guizhou
Most parts of Yunnan, a subtropical monsoon climate, with its spring season of solar water heaters available to good effect, and without cost to the water heater pipe insulation. This high penetration of solar water heaters, air pure, full of sunshine, has a unique geographical and climatic conditions and the environmental awareness of people with higher energy. Water heater is mainly flat, because the price is relatively low. Vacuum tube solar water heaters also have a certain market (price lower than the flat tube for now, read this sentence deleted). Guizhou is located in the plateau, the terrain and climate, and vertical changes significantly, cloudy, fog more, the use of solar water heaters must be auxiliary heat source (electricity, gas) in order to achieve all-weather hot water supply. Due to climate topography and other reasons, Guizhou, solar water heaters use less common.
