Blue express dispatch (reporter WangQinShuai) on the 24th of November, laiyang a citizen home solar energy water heater dozens of root collecting-heat tubes explosion, and investigate its reason is at noon, the citizens to anhydrous solar water heater process add cold water. November 25th, the reporter interviewed related industry experts, the expert suggests citizens to solar energy water heater to regular maintenance, prevent for components ageing and cause accidents.
November 24th noon, live in dongguan LaiYangShi let lady for solar panel energy water heater in water, dozens of root specification of sudden burst. "Yesterday the sun is good, I want to bask in some hot water in the evening, water up." November 25th, in the face of the reporters' queries, let woman recalled. Can in any woman opened the tap water 35 minutes, suddenly heard the second floor platform bang sound. She ran to the place of the solar energy water heater on the platform of a look, at present of scene let her silly eye. "Two solar water heater collecting-heat tubes are burst, to add has 40 root." Any lady told reporters.
November 25th, the reporter saw at lady home specification of fragment distribution in two solar energy water heater around. "Yesterday I make a phone call to ask solar energy water heater vendors, they inquired about the details, tell me may be because the operation of water caused by wrong." Any lady told reporters. "The past also know best don't at noon when solar water heater to add water, have never thought or negligence." Let woman said she in other seasons are attention, avoid at noon the sun when the strong to the solar energy water heater in the water, "but it is winter, the temperature is not so high?" Any woman or the solar energy water heater collecting-heat tubes explosion it don't understand.
To this, reporter contact in LaiYangShi engaged in the solar energy water heater installation work more than 10 years YuMingJiang teacher, in the teacher tells a reporter, generally solar cell thermal collectors explosion usually have three reasons, "pipeline aging, scale mural and improper operation, the first two reasons to be user timing maintenance solar energy to avoid, and operation will need to user attention." In the power off the water or run out of hot water after forget adding water, strong sunshine point-blank specification of water heater, can lead to tube air temperature of 200 degrees Celsius above, and then into a cold water, hot and cold temperature difference too easy to cause the specification of fracture or explosion. Therefore, usually operation to pay attention to, but also on a regular basis solar energy to do maintenance, prevent for components ageing and cause accidents.
