Water heaters always produce cold water first, then hot water. What is the solution?
Simply speaking, the hot water circulation system is to pump the cold water in the pipeline back to the water heater for heating in idle time, and then re-inject the heated hot water into the pipeline. Its core is to have a reflux pump or circulating pump. There are two main modes of hot water circulation system, one is the installation mode of return pipe, and the other is the installation mode without return pipe. All return pipe installation methods need to be embedded in the water and electricity decoration. According to the different circulating pipes, it can be divided into large circulation and small circulation. Large circulation means that all hot water pipes are connected in series. From an intuitive point of view, there are three water pipes at the water intake point. The arrangement of large circulation pipeline can ensure that the faucet is turned on and hot water will come out in a second or two. No matter the way of small circulation is from the far end of water point to return pipe and then to backwater, it is actually a way of main circulation. If the building area is large, there are many floors, and the distance from the water intake point to the main circulation road is long, it will take more than ten seconds for hot water to come out in actual use.
If the house has been decorated, it will have to be without a return pipe. At the far end of the water intake point, a one-way valve is used to connect cold and hot water, and a part of the cold water pipe is used as a circulating water pipe. This installation method does not need to embed return pipe in advance, but its disadvantages are obvious. When using cold water, there will still be hot water flowing out. Another disadvantage is that some modes of backwater cannot be used, and these modes are all relatively energy-saving modes.
Just install another water heater in front of the water heater.
I have the same problem. Before taking a bath, I turn on the shower faucet, put the shower in the bucket, let it run for a while (about 20 seconds) and it can be used normally!
If you think this method is troublesome!
I suggest you change a zero-cold water heater.
At present, this water heater sells well in the market, and the price is not too high (more than 2000 yuan).
Just get a return pipe when decorating.
Add a small kitchen treasure and it will be solved
