With reference to the attached drawing of specification, by being further described to specific embodiment of the present utility model, make
The technical solution of the utility model and its advantage are clearer, clear and definite.It is to show to describe embodiment below with reference to attached drawing
Example property, it is intended to explain the utility model, and it is not intended that limitation to the utility model.
As shown in Figure 1, a kind of central hot-water system, including：Gas heater, the domestic hot-water being connected with gas heater
System, heating system, bathtub heat-insulation system, and water inlet manifold 13, the water inlet manifold 13 is hot water supply system, heating system
System, bathtub heat-insulation system supply water.
Wherein, the gas heater includes 1 and second heat exchanger 2 of First Heat Exchanger, is connected with First Heat Exchanger 1
Heat outlet pipe 3, radiator 4, heating water return pipe 5, the First Heat Exchanger 1 and heating outlet pipe 3, radiator 4, heating water return
Pipe 5 collectively constitutes heating loop, and the first water pump 6 and expansion tank 7 are equipped with heating loop.
Plate heat exchanger 8 is connected between heating outlet pipe 3 and heating water return pipe 5, the plate heat exchanger 8 passes through pipe
Road forms bathtub insulation circuit with bathtub, and the second water pump 9 is equipped with bathtub insulation circuit.The plate heat exchanger 8 passes through three
Port valve 16 is connected with heating outlet pipe 3 or heating water return pipe 5, to switch as needed.
Domestic hot-water's outlet pipe 10, domestic hot-water's return pipe 11, second heat exchanger are connected with the second heat exchanger 2
2 collectively constitute domestic hot-water circuit with domestic hot-water's outlet pipe 10, domestic hot-water's return pipe 11, are equipped with domestic hot-water circuit
3rd water pump 12.
Water inlet pipe of the water inlet manifold 13 directly with the second heat exchanger 2 is connected, and is divided by water injection valve 14, switch valve 15
It is not connected with heating loop, bathtub insulation circuit.
The operation principle of above-mentioned central hot-water system is：
1) domestic hot-water supply：The cold water entered from water inlet manifold 13 is directly entered the second heat exchanger 2 and exchanges heat, after heat exchange
Hot water through 10 flow direction water spot of domestic hot-water's outlet pipe.According to water environment, the difference of demand, the 3rd water pump can also be opened
