Description

Technical field: [0001] The invention relates to the technical field of water heaters, in particular to a water source heat pump water heater which uses secondary heat exchange of water sources to improve overall thermal efficiency. Background technique: [0002] At present, various water heaters have been widely used, and have also been well received and recognized by users. However, there are still many deficiencies in the structural design of the current water heaters. For example, electric water heaters and gas heaters are commonly used at present. Water heaters are more prone to electric shock hazards and air leakage poisoning hazards, and both of them will cause heat energy loss, resulting in no energy saving, so it is necessary to conduct in-depth research in this area, so that the use of water heaters has the characteristics of high efficiency, energy saving, environmental protection, and safety. Invention content: [0003] The purpose of the present invention is t...

Problems solved by technology

[0002] At present, various water heaters have been widely used, and have also been well received and recognized by users. However, there are still many deficiencies in the structural design of the current water heaters. For example, electric water heaters and gas heaters are commonly used at present. Water heaters are more likely to have hidden dangers of electric shock and air leakage poisoning, and both of them will cause heat energy loss, resulting in no energy saving. Therefore, it is necessary to conduct in-depth research in this regard, so that the use of water heaters has the characteristics of high efficiency, energy saving, environmental protection and safety.
