What are the steps to install a home radiator correctly

Radiator installation is the most important link for consumers before using radiators, because the quality of radiator installation not only affects whether the radiator can be used normally, but also directly leads to the main reason for many problems such as radiator leakage and radiator not hot.

The first step: first carry out on-site measurement and design with the heating designer, determine the model, number of pieces, water inlet and outlet mode and specific installation location of the radiator, according to the actual situation and communicate with the owner, determine the model, number of groups, number of pieces per group and installation location of the radiator, and sign the radiator purchase and sale contract with the seller.

Step 2: Sign a construction agreement with the radiator construction unit to ensure the quality and risk of construction, and the general construction unit should indicate on the construction agreement that the construction of the heating system should be guaranteed for two heating seasons. It is best if the radiator sales unit and the construction unit are the same unit.

Step 3: Construction of the first phase of radiator installation. The installation of the radiator is a two-step process:

Phase I and Phase II. The first phase of the heating project includes the positioning, slotting, pipe routing (or pipe modification), pipe connection (welded pipe), installation of water collector and distributor, pressure test, etcThe second phase of the project includes: the installation of radiators (fixed suspension of radiators, the connection of valves with radiators and heating pipes), the pressurization detection of the whole system and the commissioning of radiators.

The first phase of the project needs to pay attention to the following points:

1.The first phase of the heating project is carried out after the wall is renovated, before or after the construction of water and electricity and must be carried out before the construction of other decoration processes. Before the construction of the first phase of the heating project is completed and signed by the owner, other decoration processes are never allowed to be constructed.

2.For the sake of aesthetics, if the heating installation is carried out before the decoration, the branch pipe connected between the heating main and the radiator must be buried under the floor and in the wall, and only the temperature control valve can be seen when connected with the radiatorNow there are a lot of heating engineering construction personnel in order to save trouble, the branch pipe leaks directly from the ground and connects with the radiator, so that each group of radiators has two pipes leaking outside, which is not only unsightly but also easy to break.

3.During the first phase of construction, the pipeline must be fixed and sealed according to the number of radiators, the width of a single piece, the distance between the pieces, the water inlet and outlet methods and the center distance of the interface, and the size must be accurate, otherwise the installation of the radiators in the later stage will be affected. At the end of the first phase of the project, the owner can only seal the groove after passing the acceptance on the site, and the first phase of the project will be completed.

After the completion of the first phase of the heating project, the decoration workers must pay attention to the heating pipes and facilities during the decoration process, and must not move or damage them.

Step 4: Construction of the second phase of the radiator installation. After the decoration work of the customer's home has been carried out until the wall has been painted or the wallpaper has been pasted, the second phase of the project construction, the installation of the radiator, the installation and the pressure test are qualified, and the installation of the wooden floor can be carried out.

To put it simply, it is to first look at the line of the pipe with the master, and then lay the pipe, hang the radiator, and test the pressure, you can do it, Rubens heating hopes to help you.

The installation of home radiators is divided into surface installation and installation, and the surface installation of radiators is not greatly affected, because there is no need to destroy the floor and wall, only after the pipeline is arranged, it can be installed on the surface, which is flexible and convenient, and the installation is convenient.

The steps to install a home radiator are as follows:

Step 1: Field measurement to determine the model, number of groups, number of pieces per group and installation location of radiators.

Step 2: Positioning, slotting, pipe routing (or pipe modification), pipe connection (welded pipe), installation of water collector and distributor, pressure test, etc.

Step 3: Fixed suspension of the radiator, connection of the valve with the radiator and heating pipe, pressurization detection of the whole system and debugging of the radiator, etc.

Note: In the radiator industry, there are "three points of products, seven points of installation" heating equipment with poor quality, which is mainly manifested as not warm, or unevenly warm. Whether it is installed well or not directly affects whether there is water leakage, oxidation, poor heating effect and other problems in the field investigation.

Before the installation of the radiator, have a preliminary understanding of the user's home, measure the area of the house, select the installation location, survey the water quality, etc., design the installation plan, and select the appropriate radiator installation according to the design plan.

2.Positioning the grooving. Grooves are made on the walls and floors to bury the exposed pipelines, and the depth or width of the grooves needs to be treated by special dark yellow personnel in combination with the actual situation.

3.Laying pipes and slots. According to the previously designed installation position, the branch pipe is mined and laid, and after the laying is completed, a steel channel can be laid in the branch pipe to protect the pipeline according to the actual needs, and then the closed system is used to suppress and inject water.

Laying pipes. Install radiators.

Install a wall-hung boiler.

Stress test. Customer acceptance.

Radiator concealed installation steps:

Excavation of the floor or wall.

Lay the tubing and guard the card slots.

Install the water collector and manifold.

Perform a pressure test on the radiator system.

Follow the renovation schedule.

Install radiators.

Install a wall-hung boiler.

The customer inspected and accepted the whole system of the radiator.

The radiator system is installed.

Among the current types of home improvement radiators, open pipe installation and concealed pipe installation radiators are the mainstay.

First, the method and construction points of the open pipe installation radiator.

Follow the protocol and follow the tube and secure it in the corner.

Holes in the walls are hung with radiators.

Install the heat source (wall-hung boiler) and connect the pipes.

It will be opened for use after the water test is suppressed.

Construction points: The pipe of the radiator must be strict and standardized, and try to walk the blind spot of vision.

The pipes for installing heating in open pipes are safer with a sliding tight connection.

During construction, it is best to set up the corresponding exhaust device at the high point of the system, otherwise it is easy to block the air. After the pipe is lowered to the wall, it cannot be re-routed on the wall.

Second, the method and construction points of the concealed pipe installation radiator.

The water and electricity stage of the blank room opens the pipe groove.

Lay out the heating pipes and connect them according to the method.

The heating system is filled with water pressure and the groove is sealed.

Other construction projects are carried out, and after the walls are finished, the radiators are hung by punching holes.

Self-heating needs to be connected to the installation of a heat source (wall-hung boiler).

Pressure the radiator system to eliminate water leakage.

Key points of construction: The time is strictly controlled, and the first phase of construction should be carried out before the hydropower transformation or with the time period of hydropower.

The stamping test can not be saved, after the first stage of construction and the final completion, it is necessary to test twice to prove that there is no running, rising, leaking, dripping place can be completed acceptance.

Whether it is an open pipe installation or a concealed pipe installation, the radiator must be mounted on the wall or on the floor. Generally, the ordinary concrete wall in the home can be directly punched and installed. Floor installation requires brackets, and attention should be paid to not hitting the ground pipelines when fixing holes on the ground.

1. Before the installation of the radiator, on-site measurement and design are required.

2. Generally, the radiator will be positioned first, followed by slotting and pipe routing.

3. In order to connect the pipes, the pipes need to be welded.

4. After the most basic construction is completed, the water collector and distributor can be installed.

5. Be sure to carry out a pressure test, if there is no problem with the test, start to fix the suspension and valve of the radiator.

6. Connect the radiator and heating pipe, and finally need to be pressurized for detection.

Notes:Precautions for the installation of radiators:

1. Determine the location of the radiator. The installation of radiators should not only pay attention to the aesthetics of its installation, but also pay attention to the heating effect and safety performance of radiator installation on this basis. Therefore, when determining the location of the radiator, you need to make sure that all of the above factors can play the best role.

2. The radiator is safely sealed. In the process of radiator installation, safe sealing is the key to radiator installation, so you must pay attention to no water leakage during installation. In addition, from the difficulty of construction, Suzhou decoration company suggests that you should not change the position of the radiator riser casually, otherwise, we must go to the next door neighbor's house for construction during installation, which will affect the normal life of the neighbor.

When the weather is cold, people will choose to install some radiators in order to keep warm. First of all, we need to determine where the radiator will be installed. The choice of the location of the radiator installation should take into account not only the problem of air convection, but also the heating of cold air.

Under normal circumstances, radiators are usually installed under or near window sills. Due to the nature of thermal expansion and cold contraction of the air, the indoor temperature is higher than the outdoor temperature in winter, and the outdoor cold air is denser than the indoor cold air due to cold contraction. The density of the air is different, resulting in a pressure difference.

Those with high density should run to sparse places.

When opening the package, please carefully check whether the radiator model, color and accessories in the package are complete. Accessories include 1 plug, 1 exhaust valve and 3 brackets. Inlet and outlet valves must be installed.

Don't ignore these processes in order to save money. During installation, the pipeline should be modified according to the installation drawings in this volume. Close the main connection valve, open the radiator inlet valve, and test with pressure testing equipment.

The test pressure should be times the normal use pressure and not less than the test pressure of the entire community pipe network. No leakage within 3-5 minutes is qualified.

Fix the radiator pendant and correct the position of the radiator with a level to ensure the horizontal and vertical of the radiator, as well as the accurate connection of the pipe fittings to the radiator. When choosing connecting pipes, special plumbing products that have been tested and approved by relevant state departments should be selected. The working pressure of pipes and fittings should be greater than the test pressure of the pipe network system.

If the network pressure cannot be determined, select pipes and fittings with a pressure of 12kg cm2. The bending radius of the pipe shall not be less than 4d. Each group of radiator inlet pipe and return pipe should be equipped with control valves, and the distance between the radiator extension pipe and the riser pipe should not be less than 200mm.

Stress test the radiator system. This is a very important step in installing the radiator. During replacement construction, workers keep valves on the pipes. After the installation is completed, the stamping test is carried out to prove that there is no running, running, dripping and leakage, and then it can be accepted.

When installing household radiators, the pipes should have a certain slope, and there should be a certain height difference between the radiators and the boilers, and the spacing should be more than one meter under normal circumstances. The diameter of the radiator pipe is generally DN-25 and DN-40, and the farthest end should not exceed 15 meters. The advantages of this diameter are:

The heating effect can be achieved completely by the method of natural circulation; Its disadvantage is that the temperature difference between the upper and lower is large, the height of the radiator can not be too low, and the decoration effect is not beautiful.

Normally, the radiator is generally installed under or near the window sill, because the air has the nature of thermal expansion and contraction, the temperature in the room is higher than the outdoor in winter, and the cold air outside becomes denser than the indoor due to cold contraction. The density of the air is different, and the pressure difference is generated, and the denser ones should run to the sparse places.

Step 1: Locate the punch.

The ground is covered with protective film and dust-free punching, which will not cause pollution to the room and will not affect normal life. This is also the biggest feature of the surface-mounted radiator, does not affect the normal life, the user determines the installation position, the installation master will be combined with the position of the operation of the hole.

Step 2: Lay the pipes.

According to the pre-designed installation position to determine the location of the pipeline, the pipeline is generally in the ceiling, baseboard and other hidden places, the laying of the open pipe as far as possible does not affect the indoor decoration, whether it is the open or concealed radiator, it is necessary to plan the path of pipeline laying in advance, and the concealed master can carry out on-site operation.

Step 3: Install the radiators.

In the process of installing the radiator, the radiator should be placed smoothly, and the level should be used for measurement, which must be firm. Then connect the valve connection to the inlet and outlet valves, and reinforce them after checking that they are correct. The radiator that has been concealed must be tested for pressure, and only the radiator product after the pressure test can ensure that there is no water leakage.

The installation of radiators is relatively simple, especially surface-mounted radiators, as long as you buy radiators and pipe fittings, then punch holes and lay pipes, and finally hang the radiators. Of course, it's best to suppress and test it. Rubens Heating hopes to help you.

In the past, the cast iron sheet needed to be combined with a pair of wires and then painted, but now it is not necessary to pay attention to the size of the inlet, and install the oil blade or valve with a hole to fix the heating. Take over the connection. Finally, the suppression test.

1. Tandem installation: This installation is very pipe-saving, and a single pipe is OK to go around the house, but it is easy to appear that the temperature of the radiator at the end of the heating cannot go up.

2. Parallel installation: water supply and return water pipelines go up in the room, and each group of radiators is connected from the water supply and the water, so that the temperature difference between the front and rear is not large, and most of the installation methods are used at present.

3. Octopus installation (need to install a water separator): such an installation, each group of heating is independent, each group of temperature difference is very small, the disadvantage is that it is necessary to purchase additional water separators, and the water supply pipes and return pipes are insulated, which are buried underground. The amount of construction is large and the cost is high.

Radiator installation location:

First, the principle of low should not be high.

According to the principle of air, the hot air rises and the cold air sinks, the higher the radiator is installed, the greater the heat loss, because the heat is emitted from the radiator, so when choosing the location, it is necessary to consider both the convection problem and the heating of cold air.

In general, the radiator should be installed under the window sill, because the radiator is close to the ground, which can not only make the indoor air convection, keep the room temperature balanced, but also heat the air from the window crack, and play a role in preventing cold.

Second, the principle of priority under the window.

The installation position of the radiator under the window does not affect the placement of furniture, and can effectively block the discomfort caused by cold air entering people. However, the specific installation location also needs to consider the specific layout of the customer's home. Radiators are available in different heights and models to meet different needs.
