My wall hung boiler used to burn gas, but now I want to change to natural gas

Gas stove to natural gas stove method:

purchase of millimeter nozzles and corresponding tools for natural gas;

Remove the millimeter nozzle on the liquefied gas furnace, use an electric drill and two drill needles of the corresponding size to ream, and change the hole diameter to millimeters;

Install the nozzle in situ, tighten it and test the leak, vent the gas in the original pipe, and then connect the pipe to check whether the connection is tight to prevent air leakage;

Cover the gas stove panel so that the gas stove is changed.

Professional relocation, in addition to professional service personnel, requires natural gas nozzles sent from the original factory. Don't do it yourself, correct the mistake, it will not be able to use gas or the stove will be damaged, or it may lead to air leakage and poisoning.

Natural gas is a multi-component mixed gaseous fossil fuel, the main component is methane, and a small amount of ethane, propane and butane, no waste residue and wastewater are produced after combustion, compared with coal, liquefied gas and other energy sources have the advantages of safe and clean use.

Gas and natural gas are different in themselves, and gas stoves and natural gas stoves will also be different, so it is very important to choose the right stove for the safety of gas use.

This depends on which brand it is, the current brand is different, the product is replaced by gas gas to natural gas, and there are three ways to replace it theoretically:

1. Only replace the nozzle (less common);

2. Replace the burner (also known as fire discharge) and nozzle (this is the most common);

3. Replace the gas valve, burner (also known as fire discharge), and nozzle (accounting for a certain proportion).

In this case.

Only the burning fire platoon needs to be replaced.

And adjust the parameters.

Floor heating is mainly composed of two categories, electric floor heating and water floor heating, electric floor heating is the use of heating cable heating, water floor heating mainly uses hot water circulation to heat, but the hot water of water floor heating can be used to use electricity to burn, can also use natural gas and liquefied gas heating to obtain, the heating center of floor heating is a wall-hung boiler, and a small natural gas boiler can be added.

Natural gas heating is burned by the wall-hung boiler to achieve the purpose of heating, and the wall-hung boiler is connected to the underground buried pipeline, which can generally realize the dual circuit of floor heating at the same time**.

Generally speaking, the floor heating system can be changed to a natural gas wall-hung boiler, but it needs to be analyzed on a case-by-case basis.

Whether the gas pipeline and smoke exhaust pipe are fast or not meet the requirements. Gas and smoke extraction pipes need to be ensured to comply with local regulations and standards, and installation work needs to be carried out by professionals.

Theoretically, it is possible to change underfloor heating to natural gas wall-hung boiler heating, but there are many factors to consider. First of all, it is necessary to determine whether there are already pipes and related equipment suitable for the use of natural gas in the home; Secondly, it is necessary to consider whether the replacement equipment will modify and process the original floor heating system, and whether these changes meet the construction and use standards, and do a good job in the corresponding construction plan and acceptance; Finally, it is necessary to calculate the cost and effect of the renovation heating, including thermal efficiency, energy saving, cost, etc., so as to decide whether it is worth the retrofit. Therefore, it is advisable to consult with a professional building and heating engineer before retrofitting so that you can fully understand, weigh and evaluate the prospects and risks of heating retrofits.

First of all, natural gas and wall-hung boiler are not matching, wall-hung boiler is also one of the user's gas equipment, such as water heater and gas stove, etc., if any of your equipment needs gas, you can apply for access, ** air conditioning is air conditioning, can be heated in winter, can not replace the wall-hung boiler (water heater) bathing and cooking need hot water.

So according to your needs, if you want to use hot water, you can install a wall-hung stove, and then apply for natural gas to enter the household, if you want to use an electric water heater, including an induction cooker for cooking, you can also use natural gas.

Natural gas is a kind of gas, which produces heat after combustion, and the household equipment that can be connected to it can be connected is: gas wall-hung boiler: dual-system, one machine dual-purpose, heating + hot water can be provided in winter, and only hot water is provided in summer.

It is suitable for household heating (no central heating), and additional heating systems need to be installed, such as radiators, floor heating, fan coil units, etc.

Gas water heater: used to provide hot water (35-60) for bathing, vegetable sink, washbasin, etc. Gas stove: stove, used for home cooking: hot drinking water, cooking and frying and other meals.

Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and biogenerated gas, etc.).

The long-term common definition of "natural gas" is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally contained in the formation. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases.

Choose a suitable location, install a gas heating furnace (need to be selected and installed by the gas company), lay gas pipelines, and renovate the original heating pipes

Remove the original heating stove, clean the radiators and the old heating return pipes that you want to keep; Depending on the location of the gas wall-hung boiler, the water and water pipes that connect all radiators are retrofitted and connected – all connected to the water supply and water supply of the wall-hung boiler. It is recommended to use PPR hot water pipes for construction, and the original galvanized pipes are also recommended to be replaced.

Suggestion: Reserve a faucet at the lowest point of the return pipe - it is very convenient to clean the pipe and reduce pressure.

Specific transformation steps:

1. Select a suitable location, install a gas heating furnace (the gas company needs to select and install the site), and lay the gas pipeline;

2. Refurbish the original heating pipeline

a. Remove the original heating furnace, clean the radiator and the old heating pipe you want to keep;

b. According to the location of the gas wall-hung boiler, transform and connect the water and water pipes of all radiators - all of them are connected to the water supply and water of the wall-hung boiler. It is recommended to use PPR hot water pipes for construction, and the original galvanized pipes are also recommended to be replaced (they can also be retained, but they should be thoroughly cleaned);

Here's a suggestion: Reserve a faucet at the lowest point of the return pipe - it is very convenient to clean the pipe and use it to reduce pressure.

Buying a new set is about 4-6 thousand, that's the cost... A dozen dollars a day, dozens of dollars, if you can central heating is the best.

No. An expert from the safety department of the Zhengzhou Municipal Administration said that there are differences between the two types of gas pressure and delivery methods, "According to the regulations, the type of gas used in the stove cannot be changed." If it changes, there will be a serious security risk".

An engineer surnamed Bai from the Provincial Energy Conservation and Gas Appliance Product Quality Supervision and Inspection Center said that the rated pressure of the liquefied gas tank is greater than the pressure of natural gas. If the hose is used for a long time, there is a possibility that the hose may rupture due to high pressure.

In addition, due to the increase in pressure, the modified liquefied gas stove causes insufficient gas combustion and produces a large amount of carbon monoxide, resulting in poisoning.

Natural gas is a multi-component mixed gaseous fossil fuel, the main component is methane, and a small amount of ethane, propane and butane, no waste residue and wastewater are produced after combustion, compared with coal, liquefied gas and other energy sources have the advantages of safe and clean use. Therefore, the country is popularizing natural gas in large quantities, and now more and more community users are connected to natural gas, and the gas stoves that have been using liquefied gas are now not suitable. So how can we change the liquefied gas stove to a natural gas stove, in fact, it is very simple, we only need to change one place, the size of the gas nozzle.

Tools Raw materials.

Screwdriver gas nozzle.

Method steps.

To know what the nozzle looks like, the nozzle is generally made of copper and installed on the valve body. There is a small hole in the middle, and that is the nozzle.

To disassemble the gas cooktop panel, you can remove the panel by removing all the screws on the panel with a screwdriver.

Remove the nozzle directly, and the burner with a low fire in the center has two nozzles in one valve body. Twist it with a wrench or pliers of the appropriate size. The burner is not an obstacle, as there is a spring under the damper and there is room to remove it. If you don't have enough space, just remove the stove first.

It is important to enlarge the nozzle and pay attention to this step. One; It is to use an electric drill and two drill needles of the corresponding size to ream, and the nozzle of the household gas stove is generally a large fire and a small fire. Note that the hole should not be drilled too large and crooked, otherwise it is easy to appear yellow flame and smoke exceeding the standard.

Two; Go directly to the hardware store and buy a natural gas nozzle to replace it.

Install the nozzle in situ, tighten it and test for leakage, and use a lighter to check whether there is air leakage at the nozzle connection after ignition.

Cover the gas cooktop and complete the transformation.

end precautions.

If you have the ability to do it and have time, it is recommended that you can transform it yourself.

It can also be used by modification, but for safety, it is best not to modify it yourself. Or use natural gas special stove insurance.

Summary. The change of coal-fired boiler to gas-fired boiler is mainly to transform the burner, furnace arch and furnace wall, and the pressure element part of the boiler body is basically unchanged.

In no? Hurry up and speak.

In the dear.

My dear one has already sent it to you.

Okay, I'll take a look when I'm free.

Okay pro.

Summary. The modification steps are as follows: 1. First disassemble the gas stove, then according to the type of gas stove, find the locked screw, unscrew it with a screwdriver, and take it off and put it aside.

2. Use a suitable wrench to remove the nozzle and stove head of the gas stove. When the burner head is removed, there is a spring at the bottom of the damper plate, and there is room to remove the burner. 3. Go to the hardware store and buy a nozzle with a size, if you don't understand, you can directly inform the merchant that the nozzle is used to change natural gas.

4. Then use a suitable drill needle to rectify the ignition nozzle of the natural gas stove, the large fire port needs to be changed, and the small fire hole needs to be changed. 5. After installing the nozzle on the stove, fix it, and then turn on the gas to see if it can breathe fire normally. If it can be used normally, it means that it has been successful, otherwise it needs to be rectified.

Dear, hello ruler, I am an expert in the field of life. At present, the Ling Song liquid is found through the white clouds for the cherry blossoms. There is a tutorial for changing wall-hung boiler gas to natural gas. The tutorial is as follows.

Summary. Hello, gas appliances cannot be used normally after the pipeline gas is changed to natural gas.

Because the pressure of piped gas, piped liquefied gas and piped natural gas is different, it cannot be used normally.

After switching from piped gas to natural gas, can the original stove be used?

Hello, glad to receive your question, please give me a few minutes to give you the most detailed answer.

Hello, gas appliances cannot be used normally after the pipeline gas is changed to natural gas. Because the pressure of piped gas, piped liquefied gas and piped natural gas is different, it cannot be used normally.

The difference between gas and natural gas is that the nozzle is different The nozzle diameter of natural gas is relatively small You don't have to worry about replacing the nozzle, any maintenance department that sells stoves has replacement nozzles, but it is not recommended that you use it this way, because there will be safety hazards! Thank you for your question and have a great day!
