What is the return system for hot water? Is it necessary for ordinary families to install it?

Hot water return system: refers to the electric water heater.

Make a return pipe on the water outlet.

The road system software is intended to heat the water from an electric water heater to the heating pipe in the middle of the faucet. Since the heating pipe between the electric water heater and the tap does not have the effect of thermal insulation, the boiling water in the pipeline will turn cold after a long time. That causes 2 problems:

waste of water resources; It is not very convenient to apply boiling water, and you need to wait for a few seconds or more seconds or even longer each time.

There is no need to install the return system software for general boiling water, including temperature controller, return pipe, and unilateral check valve.

The temperature controller is used to control the return water circulation when the water in the hot water pipe is monitored.

In the case of low temperature, run the circulating water pump to transmit the cold water in the hot water pipe to the water inlet (cold water pipe) of the water heater, and at the same time run the water heater to carry out heating, and wait for the temperature of the water in the hot water pipe to achieve the normal ambient temperature and terminate the circulation system.

The return pipe is installed on the hot water pipe, and the tail end of the hot water pipe is usually connected to the outlet of the water heater inlet with the layout of the hot water pipe.

Install a check valve at the return pipe at the end of the hot water pipe to prevent the cold water from the return pipe from flowing back into the hot water pipe, and it is usually not recommended to install the boiling water return system software, because most people use the water heater to consume electromagnetic energy or natural gas.

The software of the return system is more energy-intensive. Unless it is installed with medium to large energy consumption water heaters, such as solar power generation, air energy water heaters.

Water heaters, ground source heat pump systems and other water heaters for environmental protection and economic development of electric energy, install heat return system software, low energy consumption, but also save water, easy to use. If it is the application of electric heating, natural gas and other low-value easily consumable electricity energy, the installation of water return system software to save water, convenience and environmental protection and energy saving are average, compared with the installation of more than one water heater.

It refers to the return pipeline system on the outlet pipe of the water heater, and the purpose is to circulate the water from the hot water heater to the faucet. Because the hot water pipe between the water heater and the faucet does not have a heat preservation function, the hot water in the pipe will become cold after a long time, and when you open the faucet to use hot water, the cold water in the hot water pipe must be discharged before the hot water flows out. This raises two problems:

One is a waste of water resources; Second, it is not very convenient to use hot water, and you have to wait for a few seconds or more than ten seconds or even longer each time.

It is necessary for ordinary households to install, which can effectively improve the problem of hot water use in winter.

It is a system that circulates hot water in the pipes. There is no need to install it, this kind of installation is too expensive, and ordinary households can buy a water heater using direct sales.

The return system of hot water means that the hot water circulates in the water pipe and will not be cold, and it is best to install a return system in ordinary households, so that the heating will be better.

A return system for general hot water, including a thermostat.

Return pipe, one-way check valve.

The thermostat is the control of the return water circulation system.

When the water temperature in the hot water pipe is low, start the circulating pump to deliver the cold water in the hot water pipe to the inlet pipe of the water heater, which has the advantage of solving the demand for hot water in time, and the cost is not expensive. The disadvantages are:

It is easy to consume high energy, which leads to frequent start-up of the water heater and an increase in the maintenance rate.

The return unit is used in conjunction with the domestic thermal water supply system (gas water heater.

Electric water heater, solar water heater.

Positive displacement water heater), there is no need to wait for the cold water discharge process when bathing, and through the function of automatic circulation of the product, it can achieve ready-to-use comfortable hot water. There is no doubt that the use of a hot water circulation system consumes more electricity, or that the water savings from the hot water return system are far from compensating for the electricity bills consumed. The significance of the hot water circulation system is to be comfortable to use, not to save water and electricity.

<>If we have a return water system installed in our home, we must arrange our pipes according to the type of machine we have. Under normal circumstances, it is recommended that you arrange two hot water pipes at the same time, which can not only do circulating water, but also meet the installation of many water heaters with the function of return water system. If you use independent heating in the home, it is not the heating fins.

If you don't use a return water system, the radiator or the floor heating will not heat up.

Only a hot water return circulation system can ensure that the heating heats up quickly.

The hot water circulation system is really easy to use, especially if there are elderly people and children at home, and there are 2 bathrooms, although the cost of making waterways in the early stage will be high, and the circulating water heater is more expensive than the general water heater, but in the long run, it is not only energy-saving and environmentally friendly, but also convenient and comfortable to use. But if the kitchen and bathroom are only separated by a wall, there is really no need to install it, after all, its installation cost and use cost are not low.

The return water system of hot water is the return pipe system on the outlet pipe of the water heater, which can circulate the water from the water heater to the faucet between the hot water pipe, so that there is hot water immediately when the faucet is opened, it is necessary to install, if there is no water return system, the cold water in the pipeline needs to be released every time the water is used, which is inconvenient and wasteful.

That is, the water temperature is kept relatively constant when the discharge stops. Not necessary, because if your house is not gas, there is no need.

The water returner is also called the intelligent hot water circulation system or the intelligent water return device. The main function is to improve the comfort of hot water use, and at the same time can save time and water. Why do you need it?

In the cold winter, when hot water is to be used in the home, after turning on the hot water tap, the first thing that comes out is the cold water in the pipe. Hot water will only come late when all the cold water in the pipes is discharged, so that you will wait for more than three minutes in vain for hot water, and even 5 minutes in the villa, you will not only waste water, but also time. It is an integrated unit:

It integrates the hot water circulating pump, pipe fittings and intelligent controller through the sheet metal shell, which saves the trouble of installing each fitting, greatly improves the stability of the product, and has beautiful appearance, simple installation, diverse control and easy to use. When you install the water return device and need hot water, start the water return device dozens of seconds in advance, and you can realize "the shower comes as soon as the hot water is turned on", and the water return card.

It is necessary to install a hot water return system during renovation. Depending on your personal needs, the role of the backwater is to circulate the hot water in the backwater management, so that when you need hot water, you can turn on the faucet and have hot water. Since the household hot water circulation system can be turned on immediately, it is already hot water as soon as it is turned on, and there is no waste of water.

Ordinary water heaters can be said to waste at least one minute of water. The water that has just been turned on is cold, then slowly turns into lukewarm water, and finally turns into hot water.

1.1-2 minutes before using hot water, the return device will circulate the cold water in the hot water pipe back to the water heater; When the prepared clothes enter the bathroom, hot water fills the pipes. At this time, turn on the faucet, there is hot water.

Just like staying in a five-star hotel, there is no need to wait for hot water, which saves time and greatly improves the comfort of using hot water. The water return device has a thermal insulation function. If the water temperature in the return device is low, it will automatically turn on the insulation, which is basically equivalent to an electric water heater, so it will increase a certain amount of power consumption, but not much.

2.Backwater is all about forcing water to flow when we're not using it. Cold water is forcibly pumped back into the water heater, tricked into the gas water heater to start, or mixed directly into the electric water heater tank.

At present, when the water heater in a large room is too far away from the water point, in order to avoid waste, it is necessary to return the water pipe of the water heater to the farthest faucet, so that people can turn on the hot water faucet and have hot water coming out at any time, so that a household hot water return device is produced, which is recommended to be installed without exceeding the budget, which can be convenient for yourself.

3.The installation of the return pipe is also very particular, we don't need to pull a return pipe at each faucet, we only need to pull a return pipe at the end, let it flow back to the water heater, and then install a temperature sensing device and a check valve from the return pipe to the cold water pipe, so that the water in the water pipe can be directly pumped back to the water heater for heating. Users of the return pipe can use the temperature control, water control, time control and remote control modes of the return water device, which is more convenient to use.

The above is the answer to the question of whether it is necessary to install the hot water return system during decoration.

It is necessary, because after the installation of the water return system, the effect of saving water can be achieved, and the speed of water discharge is relatively fast, but the length of the line must be considered, and the hot water can be accessed anytime and anywhere. There will be no waste of cold water.

There must be a need to install it, it will make the home very warm, and such a system can also improve the safety factor and performance in life, so I think it is completely necessary.

I think it is necessary to install it because if there is no return system, it can cause damage to the water pipes and may also lead to contamination of the water source.

The main function of the return water system, also known as the hot water preheating circulation device, is: through a set of devices, to preheat the cold water in the hot water pipeline in advance, so that when the user uses hot water, there is no cold water in the pipeline, and the hot water is released when the faucet is opened. If it is a single floor (or attic, split-storey) with a floor area of no more than 100 square meters, generally speaking, we do not advocate the installation of a return water system, mainly because of the high installation cost and operating expenses.

Of course, with the improvement of living standards, the backwater system will become more and more popular.

The backwater system is when the water stops flowing, then the water will automatically return to the original place, and the home decoration must have this backwater system to prevent water leakage, and then cause such a phenomenon.

The backwater system is also known as the hot water preheating circulation device, which is to preheat the cold water in the hot water pipeline in advance, so as to realize the hot water when the faucet is opened, many hotels generally do the backwater system, but as a home decoration, especially the construction area does not exceed 100 square meters, generally speaking, it is not recommended to install the backwater system, and the installation cost and operating expenses are high.

In this way, when the water is not used, the water return is working all the time, isn't it a waste of electricity?

The water return device is also called the hot water speeder, and the core of the water return device is the water pump, which can achieve the effect of hot water circulation. The water returner is to force the water to flow when we are not using it. The cooled water is forcibly pumped back into the water heater or mixed directly into the tank of the electric water heater.

During this process, make sure that there is hot water in the hot water pipes at all times. In this way, as soon as the faucet is turned on, there will be hot water immediately.

When I took a shower, I was afraid of the cold, and the water temperature began to increase to a higher level, but! Every time before taking a shower, the water heater has to wait for several minutes for the water to heat up, and during these few minutes, the water is flowing away, which is super wasteful! When my girlfriend heard about it, she told me Amway:

Install a water return device at home, install it on the water heater, don't wait, the water will be hot in 3 seconds, very easy to use! Many people will encounter such a situation when using hot water: every time they turn on the faucet, the hot water is always "long overdue", and the faucet needs to flow out a part of the cold water first, and wait for a long time before the hot water flows out.

If the decoration is not designed to return to the pipe, install a check valve, use the inlet pipe instead of the return pipe is recommended not to install, if you do not cancel the circulation mode, even flushing the toilet, washing clothes are hot water, who can stand it.

<> hot water pipes should be insulated, otherwise the longer the pipe, the more serious the heat loss, as for the cost, the initial investment is larger, and the longer the time, the more saving. Pipe insulation can be set with insulation pipe (the kind of insulation pipe of air conditioner is OK, the thicker the insulation effect, the better). If a return pipe is installed.

At this time, the pump of the household hot water return device starts to work, it will pump the remaining cold water in the hot water pipe to the return pipe, and then merge it into the cold water pipe, so that the water heater will come out of the hot water when taking a shower. Nothing to use. In order to keep the water outlet at a constant temperature, the water heater will heat up irregularly, wasting gas.

Later it was demolished, preferring to waste a little water.

Now, I have installed a gas water heater 16L in the kitchen. My kitchen is the front end of the water, my distribution is, kitchen to washroom, bathroom, bathroom, laundry room, my check valve is installed in the laundry room. It is more than ten meters of water pipe, and it will take half a minute to put the cold water inside, if the buried hot water pipe has dozens of meters to put the cold water for more than two or three minutes, then it is still installed, and the domestic one is about five hundred, and the water of the water pipe can be preheated for three minutes each time, and it is not running after three minutes, and it does not cost electricity and gas.

It is a system that keeps the water at a constant temperature and can be used for a long time. Its function is to keep the water at a constant temperature and does not need to be heated for a long time, so as to save electricity.
