And then can judge whether hydraulic pressure satisfies instructions for use, if satisfy instructions for use, just hydraulic pressure is enough big; Again heat(ing) coil is preheated, can guarantee like this heat(ing) coil is carried out pre-warmed security.Above-mentioned hydraulic pressure indicating device 26 can be water pressure gauge.Because the mode of the indication hydraulic pressure of water pressure gauge of the prior art is comparatively complicated; Oversimplify in order to make the hydraulic pressure indication; Be convenient to judge fast whether hydraulic pressure satisfies instructions for use; Said hydraulic pressure indicating device 26 comprises that the hydraulic pressure that links to each other with water inlet pipe 12 detects arm 29, and said hydraulic pressure detects in the arm 29 and is provided with flexible sheet 30, and the inner chamber of said hydraulic pressure detection arm 29 is separated to form two chambers of mutual isolation by flexible sheet 30; Said two chambers are respectively intake antrum 31 that is communicated with water inlet pipe 12 and the indication chamber 32 that isolates with intake antrum 31; Be provided with the indicator collet 33 that links to each other with flexible sheet 30 in the said indication chamber 32, said indicator collet 33 is provided with the qualified indicator 35 of hydraulic pressure, and the tube wall that said hydraulic pressure detects arm 29 is provided with hydraulic pressure indicating window 28; When the qualified indicator 35 of hydraulic pressure was positioned at the visual range of hydraulic pressure indicating window 28, the elastic deformation amount that flexible sheet 30 takes place under the effect of hydraulic pressure was more than or equal to predetermined value.Above-mentioned predetermined value is the hydraulic pressure elastic deformation amount's that flexible sheet takes place under the hydraulic pressure effect when just satisfying instructions for use a value; The elastic deformation amount of flexible sheet is during more than or equal to predetermined value; Hydraulic pressure satisfies instructions for use certainly; At this moment the qualified indicator of hydraulic pressure is positioned at the visual range of hydraulic pressure indicating window, just can observe the qualified indicator of hydraulic pressure from the hydraulic pressure indicating window.For example shown in Figure 3, the top of indicator collet 33 is provided with qualified indicator 35 of hydraulic pressure and the defective indicator 34 of hydraulic pressure, is the qualified indicator 35 of hydraulic pressure between defective indicator 34 of hydraulic pressure and the flexible sheet 30; The top of indicator collet 33 is a hydraulic pressure indicating window 28, and when the water in the intake antrum 31 made flexible sheet 30 to indication chamber 32 direction generation strains, indicator collet 33 was moved under the drive of flexible sheet 30; If at this moment hydraulic pressure is not enough; Then the elastic deformation amount of flexible sheet 30 can only observe the defective indicator 34 of hydraulic pressure from hydraulic pressure indicating window 28, when hydraulic pressure satisfies instructions for use less than above-mentioned predetermined value; The elastic deformation amount of flexible sheet 30 is more than or equal to predetermined value; Can observe the qualified indicator 35 of hydraulic pressure from hydraulic pressure indicating window 28, can find out thus, if can observe the qualified indicator 35 of hydraulic pressure from hydraulic pressure indicating window 28; Explain that then hydraulic pressure satisfies instructions for use, at this moment heat(ing) coil is preheated safer.In addition, the defective indicator 34 of above-mentioned hydraulic pressure is provided with in order to observe convenient, that is to say that the defective indicator 34 of above-mentioned hydraulic pressure also can not be provided with, and can't observe the qualified indicator 35 of hydraulic pressure from hydraulic pressure indicating window 28 and just explain that hydraulic pressure does not satisfy instructions for use.Further be;
