For my current water heater, my biggest complaint is that the water temperature is not stable. Once bathed, everyone else is in a banned state. Or immediately make you hot. So this choice is only electric or thermostatic two. There are water storage type and instant heat type. That is, the hot type is opened and it is hot, and the Xiaobaobao is an instant electric water heater (however, the Xiaochubao's water output is relatively small, generally less than 6L, and in fact there are still a lot of large amount of water out there). However, taking into account the relatively high cost of water heaters, I directly ruled out the money slave. Water storage type, as the name implies, is a combination of heat and water storage, the advantage is to save money, half price trough hot water storage, etc. need to be reused. However, XX made a sharp protest against his large size and the timeliness of the water. Say Good Bye. Then only the constant temperature is left. Immediately understand what is the temperature on the Internet. According to the relevant regulations of the national standard for gas water heaters, when the water pressure fluctuates, the fluctuation range of the outlet water temperature cannot exceed ±3°C. This relies on the computer board chip (CPU) in the constant temperature system to feed back the data according to the water pressure sensor's induced water pressure change and the temperature sensor's sensing temperature change at the hot water outlet, and automatically outputs the pulse signal to control the "gas proportional valve" to accurately adjust the gas. Size, keep the output water temperature constant. The thermostatic effect depends on what kind of "gas proportional valve" and the speed of its response. The new constant-temperature gas water heater can control the fluctuation range of water temperature to ±1°C. It seems that I chose the right type. At a group buying meeting, I met Aunt Wan. Ah Lun was very sincere to help me introduce their family's products, and finally because of Aunt's sincere attitude, so that I leave a good impression on MACRO. However, because the homework did not do a good job of understanding the machine and the market price did not control, it was not determined. However, after returning home, he ran several supermarkets and Suning Gome and the like and probed the price. Let me worry about the price of TG. Finally, after the tile was finished, it really set 10G3 in Macro. Water heaters are free to install, but the material is money. Smoke pipe money, angle valve to money, gas valve also need money. I have heard that someone installed a water heater to spend 600 things. As the master of the new era, we must resist this kind of evil, so we use high-tech means to search the product information on the Internet. First look at the angle valve. The decoration company provided me with a Shanghai-style angle valve, and I feel like saying something like the stuff of the Soviet era - silly, solid and strong, and even better. This stuff is good for the Nine X. When you look on the Internet, you have a feeling that you must have seen it in your last life. Also heard that AMK is OK. Look again on the Internet, the type is still quite a few, yes, choose several kinds to order and look. There are good and bad things on the Internet. The corner valve has to be used for a long time, so it is not too greedy and cheap. The order angle valve came and I feel good. I considered four angle valves when choosing, and each has its own characteristics: Amico 219, ball valve, dual-purpose water, gas, solid, but looks a bit thick, cast, the handle has a directional, because it is a ball valve, so the switch is tight. JF5, ceramic valve core, water valve, full copper, different colored points, the surface is slightly flatter than 219, cast, the handle is directional, the switch is flexible, 0.16KG. JF19, ceramic valve core, water valve, full copper, colored dots, smooth surface, high brightness, forged, non-directional handle, flexible switch, 0.2KG. JF68, ceramic valve core, water valve, full copper, no color point distinction, smooth surface, high brightness, forged, handle directional, flexible switch, 0.2KG, silk mouth is slightly longer than JF19. After comprehensive consideration, choose 219 as gas valve, JF19 as angle valve, JF68--B plan. JF5 eliminated his family. hose: Ordinary stainless steel hose: 20, 30, 40, 50cm in length... Can be bent, hard, cheap, common. Retractable stainless steel hose: 30, 40, 50cm in length. Bend, softer, the biggest feature is the claim can be elongated 1 times, expensive, and less common. I bought 30CM, one is 7.4 and the other is 20. Others are some of the parts I need to imagine, such as elbows, external wire training and so on. The family portrait is as follows: 12/18 began to install. In the morning, I contacted the installation company again and said that it must arrive in the morning. 9:30 When I arrived in my new home, I took out the equipment bought on the way and the newspaper slowly read it. PS: The newspaper is a good thing. It can be seen and paved on the ground when there is no chair, or it can be packed in a heavy bag. It is a must-have item for home travel. ... During the period, several telephone calls were made to urge the installer to come. ... 12:30 The installer finally came. The young man is young. My prayer did not work and the problem really appeared: 1. The installer does not have a vise. Since the nozzles did not enter when the tiles were tiled, it was difficult to fasten them without a tiger's pliers, especially in my family. The little masters used stone carving techniques and simply put a few stuffy heads out. The water heater in my house was twisted and became Xman, which is not a good idea. Followed by the test machine. . . No nonsense, one success. Also took the painter's shampoo to check the gas pipe. Next time, ask the younger brother to eat candied gourd. Billing list: Angle valve JF68*2 26 6 points iron tube*1 2 Retractable stainless steel hose*2 40 Ordinary stainless steel hose *1 7.4 Copper elbow*1 10 50cm smoke tube*2 50 Smoke pipe elbow*1 30 Total: 165.4 NG: The original vertical smoke pipe installed 20+30 for me. I use my elementary school finger to calculate, 20 + 30 = 50cm, then he directly used 50cm, not to have to. Immediately asked to change into 50cm, it became. Qi family intimate tips: Gas water heater daily maintenance precautions 1. Always check for leaks in pipes, valves, ball valves, solenoid valves, hoses, etc., and repair them if necessary. 2. Ensure that there is adequate ventilation for the gas water heater use environment. 3. Do not put the gas cylinder sideways. Gas water heater maintenance and repair 1. If the water heater is not used for a long time, the valve of the gas pipeline before the water heater should be closed; 2. When using a rubber tube to connect the water heater, check whether the rubber tube is cracked. It is best to replace it once every two years; 3. Because the gas smells are odor, when you feel that there is such a taste, there is a leak phenomenon, do not start any electrical equipment at this time, open the windows and doors in time, close the gas valve, check the leak point, if you can not solve, please Promptly call the phone and ask a professional to solve it.

2. The tube is buried deeper and angle valves can be used as alternatives. The gas pipe can't use the original 6-plus silk, but had to go to the outside of the store to find supplies. Finally found an iron 6 wire replacement. The image of the water heater is bad.
3. The MACRO water heater is the only one left and right in my opinion.
4. When installing the water heater, I repeatedly demanded that the low point of the machine is low and the result is still higher. Fortunately, I prepared a super weapon - retractable stainless steel hose, painter and water heater installation work is to pull it up by 5cm. Finished the last hot water pipe link.
