Description

technical field

[0001] The invention relates to a water heater in the technical field of solar energy equipment, in particular to an all-glass vacuum tube solar water heater with a pressure-resistant inner tank. Background technique

[0002] The limitation of conventional energy resources and the increase of environmental pressure have made countries around the world strengthen their support for the development of new energy and renewable energy technologies. An important part of the strategy, solar water heaters have been widely used at home and abroad for their high efficiency and low price. At present, most of the solar water heaters used by families, enterprises and institutions in our country are all-glass vacuum tube solar water heaters. This kind of solar water heater has the advantages of low cost and high solar energy utilization rate, but its pressure resistance and safety are relatively low. If the vacuum tube bursts, the hot water in the water heater will all ov...
