What is more worth looking forward to before the Lunar New Year in 2018 is coming soon! The annual value-for-money welfare feedback gives you one year's worth of Dabo Welfare once. Click here to learn more Six months after the house was renovated, I lived in and lived in it for two nights earlier. As the master bedroom was farther away from the kitchen water heater, it took a long time for the master to release the hot water. In fact, it took this issue into consideration before the renovation. Preparing to embed the return pipe for the circulatory system, but given that uninterrupted hot water circulation is a waste of gas and electricity, it was abandoned. In fact, the bath is acceptable, put cold water before you wash it, but sometimes when you brush your teeth in the middle of the night, it doesn't really feel like it, just a cousin sent me an idle Grundfos circulating pump, plus Jingdong discount on the purchase Smart bedroom suite, so eventually decided to start a circulating hot water system. Used home equipment First popularization of hot water circulation away, if the friends have not renovated the proposal or buried back into the water, I use the cold water cycle, the drawback is that after the cycle of cold water may have a little hot water, but I still did not feel it, after all, winter It was cold It's easy to understand the return pipe. The No return pipe is in the end position, which is the main guard, adding a non-return valve between hot water and cold water, which is a one-way valve for the flow of hot water to the cold water. The specific principle we can check on their own, I feel still relatively simple, not much to say here. The Grundfos's pump quality is still relatively good, and the sound is very small, this pump is generally used in the floor heating hot water circulation, the only drawback here is not fixed, in order to fix this pump, I spent a lot The mind, fortunately, the complete family of tools and materials. The pump was sent by the cousin, so the live connection between the two ends was gone. Two 25 to 15 copper wires were used directly, and they were used to connect the hose. The This is a fixed effect, and it took a lot of thought to use two layers of paint-free eco-board (waste utilization) to hollow out the position of the water pump, and then cut a piece of stainless steel sheet to fix the water pump and press a little tire in the middle. The rubber that was cut off was loosened by the vibration of the waterproof pump. After fixing, it was convenient for me to fix it on the wall. In fact, the above steps can be completely replaced by a complete set of circulating pump system, because I have a pump, so toss the next, save a fee, and a treasure hot water circulation pump return system is really too much fake, I want more than a thousand of genuine circulation pump return systems. If you are interested, you can search for the hot water circulation system. Using this is more beautiful than me and it is also practical and functional. The The rest is installed. First, fix the water pump in a suitable place under the water heater, and then connect the water pump to the water heater inlet pipe. This is really not very beautiful ... In order to not worry, but also toss a lot, with a stainless steel plate folded a decorative cover. It looks more comfortable. Note that the power of the hot water circulating pump is the smart aqara socket of Xiaomi Mijia, and it needs to be used in conjunction with the Xiaomi Mijia aqara smart wireless switch to achieve the function of circulating hot water. The location of the water heater has been completed here, and the rest is the one-way cycle of the master bedroom. In fact, in the most extreme position, a check valve is added between hot and cold water. Since the picture was accidentally deleted when cleaning up the picture, I added it back. It is in the cold water and hot water position below the washbasin of the master bedroom to add a three-way, and then add a check valve in the middle, the direction can not be mistaken, is a one-way cycle of hot water like cold water. The Then install the aqara wireless switch in a suitable location. The location can be determined according to your habits. I'll install it in the main bedroom door. Every time you need to use it, press the aqara wireless switch and start the aqara outlet through the meter home app. To open the water pump, the hot water will flow to the cold water pipe to achieve circulation. A friend will say that this is not smart, but also closes himself. My favorite is this place of the Mi family, which can be added to the wireless switch through the Mi app. Realize the aqara socket after pressing the switch, then delay closing the socket, judging according to the distance of your home's water pipe, usually about one minute is enough. In this way, it is realized that the hot water is circulated only when it is necessary to use the main hot water, and no resources are wasted. The general hot water circulation system is controlled by a remote control and a temperature sensor. Of course, if you feel that you have trouble with the switch, you can also use the meter body sensing device to achieve the same function, because at present I only bought a set of equipment, only a body sensor, used in the home automatically turn on the lights, and later consider buying a put In the toilet, the pump circulation is started after sensing that the person enters. One drawback here is that the kitchen is too far away from the air conditioner outlet gateway of the master bedroom, which leads to no signal reception, so I bought a multi-functional gateway in the living room by the kitchen, which I need to use later. At present, it is still practical, we have a good idea can be made based on this idea more suitable for their smart home
