Do gas water heaters with their own return water need a return pipe?

There is a gas water heater with its own return device.

Water heater return device, also called water heater circulation pump or water heater circulation device. Its function is mainly to improve the comfort of hot water use, ensure that hot water comes when it is opened (star hotel hot water standard), and at the same time can save time and water resources. The water heater return device itself is not a water heater, but an auxiliary device of the water heater, which can be considered as an ideal companion to the water heater.

The water heater return device is used in conjunction with the water heater, which can improve the comfort of water and achieve the effect of hot water coming as soon as the faucet is turned on, and at the same time greatly saving water resources. The water heater return device is small in size and easy to install, and only needs to be connected to the water pipe (can be used without a return pipe.

Installation, without destroying the original pipeline), plug in the power supply can be used, and the energy consumption is very low, only 10-20w of electricity per day. After starting the return device, before taking a bath, the hot water circulation system first circulates the cold water in the hot water pipe into hot water, so that as soon as the hot water faucet is opened, the hot water will come without waiting. This way:

Need. The built-in return function is just that the water heater has a built-in circulating water pump, which drives the water circulation in the pipe.

However, whether it comes with it or not, it needs water to form a circulating waterway, so that it can keep hot water in the pipes at all times through continuous heating**.

If the number of people is small and the frequency of water consumption is low, it is recommended to turn off this function, otherwise it will cause a waste of energy.

If you use it, you should reserve a return pipe when you do hydropower transformation, otherwise it will cost water and gas in the future.

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, tricking the gas water heater into turning on, or mixed directly into the electric water heater's tank. 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. Therefore, the core component of the water return is the water pump.

1. If there is no return pipe, you can install another return pipe, which can make up for the problem of no return pipe. If the return pipe is not arranged in the early stage of decoration, it will lead to a long waiting time for hot water when the faucet and shower are turned on, and a lot of cold water will be wasted. With a water returner, you can effectively avoid wasting water, and you don't have to wait for a long time, and the hot water can be produced in about three seconds.

2. Therefore, a water return device can be installed directly, which is under the temperature control sensor and water pump. The one-way valve at the connection between the hot water pipe and the cold water pipe under the gas water heater can effectively circulate the cold water pipe and start it at a certain time. So that the faucet is turned on, and there is hot water flowing out immediately.

3. Therefore, if there is no return pipe, the system without return pipe circulation can be installed in the later stage, and the operation is relatively simple, and the later installation is not complicated, but the cost is higher.

The backwater pipe plays a very important role, and the backwater pipe generally needs to be buried in advance during the renovation of the waterway during the decoration, and it is basically impossible to lay the backwater pipe in the house that has been renovated, but there is no need to worry.

Nowadays, the installation method of many zero cold water gas water heaters is very flexible, even if there is no return pipe, through a simple transformation of the waterway, it can also meet the normal use of zero cold water gas water heaters.

You can choose to install a regular gas water heater for use.

The gas water heater with the return function was originally designed to use nothing more than an extra return pipe.

At this time, it is necessary to replace the ordinary gas water heater, as long as the return pipe is not used. Ordinary gas water heaters are still installed normally, and only the tap water inlet pipe and hot water outlet pipe are connected.

What kind of water heater do I use for the return pipe in my house.

Four-storey private house whole house backwater, which water heater is more suitable, plan to choose two kinds of water heaters, solar, air energy, gas water heater, please give professional advice, thank you!

Gas water heaters.

Summary. Hello, add a valve before the heating and then connect a tee, one end of the tee is connected to the water outlet of the water heater, that is, the hot water outlet, the other end is connected to a valve to shower, down at the tail end of the heating first add a micro pipe pump, and then add a valve plus a tee one end is connected to the valve and then connected to the tap water, and the other end is connected to the water inlet of the water heater, so that the circuit is connected.

Do not install a sensor to install the pump, just press a switch to control the pipeline pump, when you want to take a bath, close the pipeline pump, close the valves at both ends of the heating, open the shower and tap water valves to take a bath, and in turn to heat the tap water and shower valves to open the valves at both ends of the heating after opening the pipeline pump, you can be warm.

Finish. How to make a return water in a gas water heater.

Finish.

Now the water pipes in our home are originally two pre-buried cold and hot water pipes, and due to the structure of the house, the bathroom is always far away from the water heater, and other water points are closer to the water heater, but the same hot water will not be timely; I heard suggestions to increase the circulating pump. However, there is no reserved return pipe, only a simple and rude one-way valve to add, but the high energy consumption, the situation of hot water in the cold water, the embarrassment of being said by the customer to be unsightly and messy, I heard that the zero cold water heater is coming, thinking that it is the savior of the people's hot water, but the result is only the third upgraded version of the water heater, which also brings high energy consumption.

The distance between the kitchen and the bathroom is too far away, which means that the water heater we installed is installed in the kitchen, and the bathroom is located diagonally in the kitchen. This is an obvious problem, the long lines that need to be arranged from the kitchen to the bathroom. If the area of our house is particularly large, then if the gas water heater is still installed at this time, the gas water heater needs to be responsible for all the hot water in the room.

Therefore, there will be a problem of releasing a lot of cold water and still having to wait. Not all houses need to be filled with water, such as the one below, because the bathroom (the main water point) and the kitchen (where the water heater is installed) are separated by only one wall.

The heating return pipe must be installed, and the heating water cannot be circulated without installing the return pipe, and the water in the heating will become stagnant water if it is not circulated, and there is no new hot water in the house when heating, and the house will not be warm. Generally, when installing and modifying hydropower, the hydraulic master will suggest that we make a return pipe, the function of the return pipe is to circulate the water in the hot water pipe back to the water heater for heating, and only need to install a circulating pump in the later stage to realize the whole house hot water faucet is ready to use, and the distance is still close, there is no need, on the contrary, like villas, factory baths, you must need to return water to achieve hot water**, bathroom, multi-front long.

The hot water circuit is suitable for the water heater far away from the water outlet, the home area is particularly large, and it is still very beneficial to install one, after all, waiting for hot water in winter is really a test. But the cost of buying and installing a circulator is not cheap, about 50 100 yuan meters. Moreover, when in use, the hot water circulator is cycled and started more than a dozen times a day, and although it consumes less electricity, the gas cost will be amazing.

Therefore, if you want to install a hot water circulation system, starting from comfort, you can't think about expensive, think about energy saving. If you want to save water and money, or the area of your home is not too large, it is not recommended to install a hot water circulation system. The water returner has a backwater function, and the water returned is mainly the water left in the water pipe after the last bath, which is stored for heat preservation.

Answer: The purpose of installing a hot water return pipe is to establish a hot water circulation system. Why do you want to recycle hot water? The hot water we usually use in our homes has only one pipe – directly from the water heater to the point of use.

The direction of the water in this pipe is fixed, and every time you want to use hot water, you must first drain the remaining cold water in the pipe. On the one hand, it wastes time, and on the other hand, the hot water in the pipes will cool down again after using water, causing a waste of energy. At this time, we can consider establishing a hot water circulation system

When water is not being used, circulate the water in the hot water pipes. Every once in a while, let the water in the pipe enter the water heater to heat it again, and put the hot water in the water heater into the pipe, so that the pipe is always full of hot water. In this way, when we want to use hot water, we can "turn on the faucet and let the hot water flow".

Take the time to give it a thumbs up, thank you very much.

Question: If you don't do backwater, it's a waste of water.

I use a gas water heater.

The combustion is directly heated through the hot water pipe, and there is no need to install it.

The water heater must be installed back into the water pipe, because the return blood vessel can play a role in removing sewage, so that the water heater will operate normally without sewage.

Whether or not to install a return pipe can be decided depending on the size of the home. If the area of the home is not more than 150, it is better not to install a return pipe, because the installation and operation costs of the return pipe are not low. The function of the return pipe is to pump the cold water in the hot water pipe back into the water heater, reheat it and use it, and the main function of installing the return pipe is to prevent wasting water.

The return pipe must be installed, which has a certain effect, because if it is not installed, there is no way to dredge the heating water, and there is no way to replace the new water source in the water heater, and there is no new hot water to enter when heating.

Yes, so that the water heater can be kept in a hot water state for a long time, and it will not cause damage to the pipes.

It's best not to press it, so that the cold and hot water can be controlled, and although it takes a little effort to install, it can also avoid problems in the bath, so it is very good.

1. The installation method of the hot water return pipe is to add a hot water back pressure pump at the end of the hot water supply, and at the end of the hot water pipe, connect a pipe to the back end of the cold water inlet valve, and add a check valve here to prevent the hot water from flowing into the cold water pipe. 2. Then add a check valve in front of the interface of the return pipe, which can prevent the cold water from entering the hot water pipe, so that when the hot water is boiled, there is no need to put cold water, but there is hot water directly. 3. After installing the hot water pipe, you can choose the water flow opening mode, vacation mode, intelligent mode and remote control mode at will, so that the daily life is more convenient and more energy-saving.
