How to coil water heating ondol: analysis of hot topics and hot content on the Internet
Recently, water heating Kang coil technology has become a hot topic in the fields of home decoration and energy-saving heating. This article will combine the hot content of the entire network in the past 10 days to provide you with a detailed analysis of the methods, precautions and common problems of water heating ondol coils, and provide structured data reference.
1. Basic principles of water heating Kang coil
Water-heated Kang is a technology that uses hot water circulation to dissipate heat by laying hot water pipes on the ground or inside the Kang body. The core lies in the rationality of coil layout and material selection.
| Coil type | Applicable scenarios | Advantages and Disadvantages |
|---|---|---|
| spiral coil | Large area kang body | Even heat dissipation, but construction is complicated |
| Back-shaped coil pipe | Small area kang body | Simple construction, but uneven heat dissipation |
| Double spiral coil | Alpine areas | High heat dissipation efficiency and high cost |
2. Water heating Kang coil construction steps
According to recent popular tutorials on decoration short video platforms, water heating Kang coil is mainly divided into the following steps:
| steps | Operation content | Things to note |
|---|---|---|
| 1. Basic treatment | Clean the surface of the kang body and lay an insulation layer | Make sure the base is smooth and dry |
| 2. Boundary insulation | Install boundary insulation strips | Prevent heat loss to the wall |
| 3. Lay reflective film | Paving aluminum foil reflective film | The seams need to overlap by 5cm |
| 4. Coil construction | Lay pipelines according to design drawings | Keep tube spacing consistent |
| 5. Stress testing | Inject water and pressurize to 0.6MPa | Keep pressure for more than 24 hours |
3. Answers to recent hot questions
Based on the popular questions and answers on Zhihu, Baidu Zhizhi and other platforms, the following high-frequency questions are organized:
| question | Expert answers |
|---|---|
| What is the appropriate spacing between coils? | In the north, 15-20cm is recommended and in the south, 20-25cm is recommended. |
| What material is best for pipes? | PERT pipe is the most cost-effective, and PEX pipe has better high temperature resistance |
| Do I need to install a circulating pump separately? | It is recommended to install additional equipment if the area exceeds 15㎡ to ensure circulation effect. |
| How to prevent pipes from getting clogged? | Install filters and clean the system regularly |
4. Price reference for water heating kang coil materials in 2023
According to recent sales data from major e-commerce platforms, the prices of mainstream materials are as follows:
| Material name | Specifications | Unit price (yuan/meter) | Brand recommendation |
|---|---|---|---|
| PERT floor heating pipe | DN16×2.0mm | 3.5-5.0 | Rifeng, Taurus |
| XPS insulation board | 20mm thick | 15-20/㎡ | Owens Corning |
| Aluminum foil reflective film | 50g/㎡ | 2.5-3.5/㎡ | green feather |
| water separator | 4 way | 150-300 | manred |
5. Construction precautions
Based on discussions in the comment areas of popular construction videos on Douyin, Kuaishou and other platforms, the following important tips are summarized:
1. Before coiling, be sure to draw a detailed trend map and record the length of each loop to ensure that the length difference between each loop does not exceed 10%.
2. The bending radius of the pipe should not be less than 6 times the pipe diameter to avoid flow loss caused by bending
3. Corrugated casings must be installed when passing through expansion joints to prevent thermal expansion and contraction from damaging the pipes.
4. It is recommended to use pisolite concrete when backfilling. The thermal conductivity is better than ordinary cement mortar.
5. The temperature should be raised slowly during first operation, and the temperature should not rise more than 5℃ every day.
6. Future development trends
According to recent industry exhibition reports and expert interviews, water heating technology shows the following development trends:
1.Intelligent control: Mobile APP remote temperature control system has become a new selling point
2.Material innovation: Graphene composite pipes begin to enter the market
3.Integrated design: Solutions linked to solar water heating systems are attracting attention
4.Standardized construction: Industry associations are formulating more detailed construction specifications
Through the above presentation of structured data and hot content analysis, I believe you will have a more comprehensive understanding of water heating ondol coil technology. In actual construction, it is recommended to consult a professional HVAC engineer to carry out personalized design according to the specific house structure and climate conditions.
