the auxiliary water heater is communicated with the cold water main pipe 12 and provides hot water for part of the water using equipment.
In the embodiment, the main water heater 1 heats cold water to provide hot water for water-using equipment in areas with higher use frequency, such as kitchens, main toilets, common public toilets and the like, and a boiler, an air energy water heater, a gas water heater or a solar water heater and the like are usually purchased; and, this embodiment hot water circulation adopts the person in charge circulation mode, and the hot water circulates only in being responsible for promptly, and the branch pipe of connecting wash basin etc. does not participate in the circulation, can not only shorten the pipeline like this, practices thrift the fitment cost, and hot water is gone out soon moreover, and water experience is better, and the energy consumption that simultaneously can also greatly reduced later stage use hot water to produce.
In this embodiment, a water flow inductive switch 17 is further included, and the water flow inductive switch 17 is disposed on the water return pipe 13. The water flow induction switch 17 is matched with the water return device 16 for use, and opens or closes the water inlet pipe of the main water heater 1 according to the instruction sent by the water return device 16, so as to control the hot water circulating system
Furthermore, the water return device 16 also has the functions of preventing the boiler from being burned dry, preventing electric leakage, preventing lightning and the like, and the arrangement of the water return device 16 can ensure that the hot water circulating system is safer.
The water return device 16 is a hot water circulation system control center, and can realize functions of hot water temperature control, hot water timing circulation, hot water circulation time reservation or manual starting and the like.
Wherein, the hot water temperature control process is as follows: when the water temperature of the water return pipe 13 is lower than the lower limit of a set value, the main water heater 1 is started to heat water in the water return pipe; when the water temperature of the water return pipe 13 is higher than the upper limit of the set value, the main water heater 1 stops operating, and temporarily stops heating the water therein, so that the temperature of the hot water in the pipeline is kept within the set range, and the user can enjoy hotel comfort. The related hot water timing circulation specifically comprises the following steps: according to the water use habit of the family, the three time periods of morning, noon and evening can be set to be automatically opened so as to realize the automatic circulation of hot water. The manual starting process involved is as follows: before water is used, a button on a control panel is directly pressed to start hot water circulation. In conclusion, the hot water circulation is more suitable for the living habits of the owners, and is more comfortable. Therefore, in order to save energy, people can select a hot water timing cycle or a manual starting mode, and only start the main water heater 1 and the hot water cycle when needed, so that the energy can be greatly saved.
Further, the water return pipe 13 is usually a PPR hot water pipe with a nominal external diameter of 25mm or 32mm, and connects the end of the main hot water pipe 14 with the water inlet pipe of the main hot water heater 1 to provide a passage for hot water to flow back to the main hot water heater 1. Because the return pipe 13 is not directly connected with water using equipment such as a shower head, a wash basin and the like, and is only connected with the branch pipes of the water using equipment through a tee joint, the branch pipes do not participate in hot water circulation, and therefore by adopting the scheme, the hot water circulation pipeline is short, so that the heat loss generated by the hot water circulation is less, and energy is saved.
In this embodiment, a check valve 15 is further included, and the check valve 15 is provided on the return pipe 13. The check valve 15 is installed close to the water inlet pipe of the main water heater 1, and only water in the water return pipe 13 flows back to the main water heater 1, so that the water is prevented from flowing into the water return pipe 13 due to too high pressure of cold water and flowing reversely.

Therefore, by adopting the technology, the hot water generated by the main water heater 1 is only delivered to the equipment with higher use frequency and is not delivered to the shower head and the wash basin which are far away from the boiler and are used occasionally, so that the hot water main pipe 14 is shorter, the heat loss generated by hot water circulation is less, and the energy is saved.
Furthermore, the hot water branch pipe adopts a PPR hot water pipe with the nominal outer diameter of 20mm, water using equipment with high use frequency, such as the kitchen vegetable washing basin 3, the main sanitary wash basin 4, the main sanitary bathtub 5, the common public sanitary wash basin 6, the common public sanitary shower head 7, the water heating 2 and the like, is communicated with the hot water main pipe 14 to provide hot water for each water using equipment, and the hot water branch pipe does not participate in hot water circulation, so the hot water circulation pipeline can be shortened by adopting the scheme, the heat loss generated by the hot water circulation is less, and energy is saved. Meanwhile, the hot water branch pipe only adopts the PPR pipe with the nominal external diameter of 20mm to replace the PPR pipe with the nominal external diameter of 25mm used in conventional decoration, so that the reconstruction cost of the water pipe can be reduced.
Preferably, the cold water main pipe 12 is generally a PPR hot water pipe with a nominal external diameter of 25mm, and is connected with cold water branch pipes of water consumers such as the kitchen vegetable washing basin 3, the main toilet wash basin 4, the main toilet bathtub 5, the common public toilet wash basin 6, the common public toilet shower head 7, the water heating system 2 and the like to convey cold water for the water consumers.
The cold water branch pipe is a PPR hot water pipe with a nominal outer diameter of 20mm, and is used for communicating a kitchen vegetable washing basin 3, a main toilet wash basin 4, a main toilet bathtub 5, a common toilet wash basin 6, a common toilet shower 7, a far-end shower 8, a far-end hand washing basin 9 and the like with a cold water main pipe 12 to provide cold water for various water consuming devices. As the PPR pipe with the nominal outer diameter of 20mm is selected for the cold water branch pipe, and the PPR pipe with the nominal outer diameter of 25mm used in conventional decoration is replaced, so that the reconstruction cost of the water pipe can be reduced.
