What should I do if the water heater is not installed back into the water pipe?

I installed underfloor heating in that house and a gas boiler on the wall of the living balcony, but given the size of the house.

It was only 127 square meters, so no consideration was given to installing a return pipe.

Although there is no problem with the hot water coming out of the secondary bathroom next to the balcony, the main bathroom is far away, so the hot water is slow, and the effect is not very good. How do I deal with it?

One. Install a circulating pump.

I spent about 1,000 yuan to buy a circulating pump, which was installed under the water heater and above the washing machine. There are several modes of use of the circulating pump, and the automatic and time can be set, so that the problem of hot water is solved.

Of course, the power supply needs to be guaranteed, but fortunately, the socket is preset on the wall in advance, because the circulating pump and boiler, as well as the washing machine, need power.

Two. Connect hot and cold water.

It is not enough to install a circulating pump, but to connect the three-way pipe head and hose at the mouth of the hot and cold water pipe in the main bathroom. In this way, the hot water can be circulated through the cold water pipe.

There is a way, you use the cold water pipe of the faucet as a return pipe, but then the faucet can only put hot water, if you want cold water, you can only use the gas water heater.

Closed. As for the installation of the water purifier, it happened that the cold water pipe was connected to the water heater, and a cold water angle valve was vacated.

Connect the water purifier, and the water purifier is equipped with a faucet separately.

This is the only way to get the best of both worlds.

To do water purifiers, we must pay attention to quality, when it comes to quality, we must talk about the after-sales of water purifiers, water purifiers light luxury custom brand owin water purifiers, there is a special person in charge of after-sales, to deal with the product problems and other problems encountered by the first business, after-sales service is relatively perfect, many manufacturers are basically not equipped with special after-sales personnel to dock after-sales work, are borne by the business manager himself, so it is very important to choose the after-sales service of water purifiers.

Three. Install a check valve.

However, at the far end of the main bathroom, is it not enough to connect the hot and cold water pipes like that? It is also necessary to install a check valve. That is, a one-way check valve should be placed on the three-way pipe head, that is, the hot water flows towards the cold water pipe.

After this is dealt with, the problem of bathing in the large bathtub of the main bathroom and putting hot water is barely possible, which is obviously much better than not dealing with it.

The return pipe, in fact, is on the basis of the cold water pipe and hot water pipe, and then add additional pipes, which are specially used for "return water". Therefore, the function of the return pipe is to provide a path for the return water to the hot water that cannot be used up in the hot water pipe, and the residual hot water.

If the water heater is not equipped with a return pipe, you can add a return pump, add a return pump to the cold water pipe connected to the water heater, and install a circulation device in the toilet farthest from the water heater.

Add a one-way valve at the farthest end of the hot water pipe, connect the hot water pipe and the cold water pipe in series, and return through the cold water pipe, and the constant temperature mode cannot be set without the return pipe.

If there is a return pipe, we will install the check valve at the connection between the return pipe and the cold water pipe, when the hot water circulation system works, the water supply in the cold water pipe is mainly provided through the return pipe, so that if the hot water circulation system works a little longer, there is no need to be afraid of the hot water in the hot water pipe running into the cold water pipe.

The return pipe is not mandatory. Thermal circulation is not the same, and even if an external hot water circulation pump is installed, it can be installed without a return pipe.

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.

1. Hot water pipe and return pipe of hot water circulation system.

It is a connected pipe, and if the starting point of the hot water pipe is the water heater, then the end point of the hot water pipe is the return pipe.

2. Add a tee to the farthest end of the hot water pipe of the water heater and insert the water pipe into the faucet. When the hot water is circulating, the return pipe will take the cold water away from the main part of the hot water pipe, while the branch part is still cold water, and the hot water can only be used after the water in the pipe is drained.

3. The whole hot water pipeline does not use the tee to branch, connect the hot water pipe directly to the faucet position, use the toothed tee as the faucet interface, and bend the pipe to the next faucet again.

4. In the hot water circulation system, a check valve should be added.

Check valves are also known as check valves and check valves.

Reverse flow valves, back pressure valves.

The check valve is an automatic valve, and its main function is to prevent cold water from backflowing, preventing the pump from reversing with the drive motor, and the release of container media.

5. The water passing through the water heater, whether it is pressure or flow, is not as good as the pressure and flow rate of the original water pipe. When using hot water, the pressure and flow rate of the cold water pipe are high, and the original hot water faucet will also produce cold water.

Summary. Hello dear and honored to serve you.

Here for you to find out, the water heater is equipped with a return pipe to turn off the hot water outlet.

Can the water heater be turned off if it is equipped with a return pipe?

Hello, dear and dear, I am honored to serve you here, and I will inquire for you that the water heater is equipped with a return pipe to turn off the hot water.

The hot water outlet valve of the electric water heater can be closed, but the water supply valve (water inlet) cannot be closed, and it must be ensured that the cold water will automatically enter the water heater tank after opening the valve to flow water. When the outlet valve is closed, the water heater cannot be used because the water inside cannot flow. It will not cause dry boiling, and there is water in the water heater cavity.

If you have any questions here, you can ask them, and the teacher will reply to you as soon as you see the information<>

I wish you a happy life, and I think the old mountain tremor answered well, and you can give the teacher a five-star evaluation.

Summary. If there is more water in the home, it is necessary to install a check valve at the farthest water point to replace the return pipe to form a circulating waterway with real hot water. However, this kind of zero cold water effect achieved by installing a check valve is prone to the following problems:

1 There may be a "warm water flush" when the toilet flushes the toilet first, unless the water heater is turned off.

2 Nowadays, the water pipes are made of PPR material, and the cold water pipes are thinner than the hot water pipes, which will cause the water pipes to deteriorate or even burst and other unpredictable situations for several years.

3. The check valve must be installed under the basin at the farthest water point, and if it is installed at other water points, there is a certain distance from the shower, and this part of the water pipe is still cold water.

4 The water purifier will have an impact, the ice water pipe of the water purifier is 5-38 water temperature, which is not resistant to high temperature.

There is no reserved return pipe at home, what water heater can be installed?

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

My house is a duplex building, the bathroom is equipped with back water, the kitchen is not installed with back water, such as Xunyou wax fruit with gas water heater, it will be slippery and will not let go of a lot of cold water, and it will take a long time to produce hot water.

If there is more water in the home, it is necessary to install a check valve at the farthest water point to replace the recollection and scattering pipe, forming a circulating waterway to form a real full pipe of hot water. However, this kind of zero cold water effect achieved by installing a check valve is prone to the following problems: 1 There may be a "warm water flush" when starting zero cold water, which means that the first thing that comes out of the toilet flush is a section of warm water, unless the water heater is turned off.

2 Nowadays, the water pipes are made of PPR material, and the cold water pipes are thinner than the hot water pipes, which will cause the water pipes to deteriorate or even burst and other unpredictable situations for a few years. 3. The check valve must be installed under the basin at the farthest water point, and if it is installed at other water points, there is a certain distance from the shower, and this part of the water pipe is still cold water. 4 The water purifier will have an impact, and the ice water pipe of the water purifier is 5-38 water temperature brother leaky socks, which is not resistant to high temperatures.

Summary. The method of treating the return pipe depends on the specific situation, and here are some common ways to deal with it:1

Drain to the ground drain: The return pipe can be connected to the ground drain to ensure that there is sufficient drainage capacity at the drain to effectively drain the backwater. 2.

Drain to the sewer or drain line: If your home already has a sewer or drain system, you can connect the return pipe to the appropriate sewer or drain line. 3.

Use a return pump: If the water heater is installed higher than the outlet of the return pipe, or if the return pipe needs to be connected to a distant drainage point, it may be necessary to install a return pump to provide adequate drain pressure. 4.

Return Pipe Circulation System: In some cases, the return pipe can be connected to a dedicated hot water return circulation system, which can achieve hot water circulation**, so that hot water reaches the point of use more quickly and waste is reduced.

If an ordinary water heater is installed, how to deal with the return pipe.

The method of treating the return pipe depends on the specific situation, and here are some common ways to deal with it:1Drain to the ground type collapse drain:

The water pipe can be connected to the drain at ground level to ensure that there is sufficient drainage capacity at the drain to effectively drain the backwater. 2.Drain to the sewer or drain pipe:

If your home already has a sewer or drain system, you can connect the return pipe to the appropriate sewer or drain line. 3.Use the return pump:

If the water heater is installed higher than the outlet of the return pipe, or if the return pipe needs to be connected to a distant drain point, it may be necessary to install a return pump to provide adequate drain pressure. 4.Return Pipe Circulation System:

In some cases, the return pipe can be connected to a dedicated hot water return circulation system, which can circulate the hot water**, so that the hot water can reach the point of use more quickly and reduce waste.

The return pipe is connected to a pipeline at the very end of the hot water pipe and then extended to the side of the hot water pipe of the water heater, which is called the return pipe, and the return pipe and the water heater are the same pipe, that is, the hot water pipe is extended to the water heater position.

Whichever method you choose, you need to ensure that the return pipes are securely and securely connected, and that they comply with relevant building codes and safety standards. In addition, when dealing with return pipes, ensure that the water heater is used at a disadvantage and that the guidelines and recommendations of the spine manufacturer are followed and concealed.
