According to the hot-water heating system 100 of the utility model embodiment, by the first delivery port 12 of gas heater 10 is communicated with the second water inlet 21 of electric heater 20, the electric heater 20 that contains inner bag 23 is cascaded with gas heater 10, hot water in gas heater 10 can flow in electric heater 20, and can be stored in inner bag 23, electric heater 20 can carry out post bake or insulation to hot water, thereby make the first outlet terminal 30 can have uninterrupted hot water, hot water supply significantly increases and stable water outlet; These hot-water heating system 100 energy-conserving and environment-protective, practicality is good.
In correlation technique, the water side of gas heater 10 is connected with instant electric water heater 20, although this instant electric water heater 20 can heat water, because moisture storage capacity is little and power is large, cause this hot-water heating system 100 to consume energy high, the hot water amount that makes is few, flying power is poor; And heat hydraulic pressure can be subject to the impact of running water pressure fluctuation, goes out water unstable.
According to the hot-water heating system 100 of the utility model embodiment, by the electric heater that contains inner bag 23 20 is connected and is connected with gas heater 10, the water that flows into electric heater 20 is the hot water in gas heater 10, there is not mixed water phenomenon, electric heater 20 can carry out post bake or insulation to hot water, make the first outlet terminal 30 can have uninterrupted hot water, hot water supply significantly increases; And can stored hot water due to the inner bag 23 of electric heater 20, can alleviate water pressure fluctuations and fluctuating temperature, make the first outlet terminal 30 can flow out the hot water of stable water pressure and temperature stabilization, water outlet performance is good.
The hot-water heating system 100 of this structure takes full advantage of gas heater 10 and carries out complementation with the strengths and weaknesses of electric heater 20, has solved gas only water heater 10 or the insurmountable problem of electric heater 20, makes hot-water heating system 100 continue heat production water time length, power consumption less.
In example as shown in Figure 1, between the first delivery port 12 and the second water inlet 21, be provided with pressure relief safety valve 24.Pressure relief safety valve 24 can reduce the pressure that flows into the hot water in electric heater 20, avoids the heat hydraulic pressure in electric heater 20 too high, causes electric heater 20 that the danger such as explosion occur, and has improved the safety in utilization of hot-water heating system 100.

According to adopting pipeline 50 to be connected between the each parts in the hot-water heating system 100 of the utility model embodiment, for example, gas heater 10 can be by cold water pipe 51 and municipal water supply system connectivity, between gas heater 10 and electric heater 20, can be connected by hot-water line 52, the first outlet terminal 30 can be connected by hot-water line 52 with the second delivery port 22.In the time that the pipeline 50 between electric heater 20 and the first outlet terminal 30 is longer, the interior meeting of pipeline 50 retains part hot water, because pipeline 50 does not have insulation and heating properties, therefore, in the time that hot-water heating system 100 is not worked, the hot water being stored in pipeline 50 is easy to cool off.Thus, when in the time that the first outlet terminal 30 is taken hot water, need to first this part cold water in pipeline 50 be bled off and just can take the hot water flowing out from electric heater 20, thereby cause the waste of water resource.
Advantageously, the first outlet terminal 30 can be close to the second delivery port 22 and arrange, thus, pipeline 50 between the first outlet terminal 30 and the second delivery port 22 is shorter, when can flow out hot water without bleeding off too much cold water in the time that the first outlet terminal 30 is taken hot water, avoid the waste of water resource, can make the first outlet terminal 30 1 open and can flow out hot water.
Correspondingly, gas heater 10 can be close to setting with electric heater 20, pipeline 50 between gas heater 10 and electric heater 20 is shorter thus, avoid in the time that hot-water heating system 100 is opened, the too much cold water retaining in pipeline 50 flow in electric heater 20, make the interior generation of electric heater 20 mix water phenomenon, affect the performance of electric heater 20.
Due to according to the sustainable continual hot water that provides of the hot-water heating system 100 of the utility model embodiment, and hot water is in large supply, therefore, the first outlet terminal 30 can comprise multiple water parts 31 (31 '), and multiple water parts 31 (31 ') can be located at the second delivery port 22 places by serial or parallel connection.For example, as shown in Figure 1, the second outlet terminal 40 comprises two water parts 31 and two water parts 31 ', and each water part 31 (31 ') is communicated with the second delivery port 22 respectively, between multiple water parts 31 (31 '), is arranged in parallel.Thus, simultaneously water and not being affected each other of multiple water parts 31 (31 ').The type of water part 31 (31 ') can have multiple, and for example, water part 31 can be kitchen sink, and water part 31 ' can be shower.
On each water part 31, can be provided with respectively hot water outlet 311 and cold water delivery port 312, each hot water outlet 311 can be communicated with the second delivery port 22 respectively, and each cold water delivery port 312 can be connected with municipal water supply system by cold water pipe 51.Thus, in the time that needs are taken hot water, can open hot water outlet 311 hot water is flowed out, in the time that needs are taken cold water, can open cold water delivery port 312, cold water is flowed out.This kind of water part 31 structures are clearly demarcated, easily use.
Hot water outlet 311 can integratedly arrange with cold water delivery port 312.For example, hot water outlet 311 is integrated into one with cold water delivery port 312, in the time that needs are taken hot water, only hot water line need be opened and can flow out hot water; In the time taking cold water, only cold water pipeline need be opened and can be flowed out cold water.It is more convenient that the structure of this integrated setting is used, and can effectively save space.
As shown in Figure 1, the first delivery port 12 places are provided with the second outlet terminal 40, the second outlet terminals 40 and are communicated with the first delivery port 12, and in parallel with electric heater 20.Thus, can be without electric heater 20 from the hot water of gas heater 10 interior outflows, and directly flow to the second outlet terminal 40, thus can save electric energy.Because gas heater 10 can only heat the water flowing through in it, and can not store water, therefore, in the time opening gas heater 10, gas heater 10 can first flow out a part of cold water, and therefore, the second outlet terminal 40 can be less demanding water parts 31 such as water temperatures.Certainly, can be by regulating the use step of hot-water heating system 100, the second outlet terminal 40 1 is opened hot water.This is operating as: first make the first outlet terminal 30 open a period of time, and then open the second outlet terminal 40.
