How to change central heating to floor heating
With the improvement of living standards, more and more families are beginning to pay attention to home comfort. Floor heating has become a popular choice because of its advantages such as uniform heat dissipation, energy saving and environmental protection. Many central heating users hope to replace traditional radiators with floor heating, but the transformation process involves many issues such as technology, cost, and construction. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the steps, precautions and data comparison of changing from central heating to floor heating.
1. Comparison between central heating and floor heating
| Comparative item | Central heating (radiator) | Floor heating |
|---|---|---|
| Heat dissipation method | Convection heat dissipation, high local temperature | Radiation heat dissipation, uniform temperature |
| comfort | Average, easy to dry | High, feet warm and head cold |
| Energy consumption | higher | Lower (low temperature operation) |
| Installation cost | low | High (requires ground construction) |
| Taking up space | occupy wall space | Hidden on the ground |
2. Preparation work before transformation
1.Confirm heating system compatibility: The water temperature of central heating is usually high (above 70℃), while floor heating needs to operate at low temperature (40-50℃), and a water mixing device or heat exchanger needs to be installed.
2.Assess the structure of the house: Floor heating requires raising the ground by 5-8cm, which may affect floor height and height of doors and windows.
3.Choose floor heating type: Water floor heating (boiler or heat source required) or electric floor heating (suitable for small areas).
| Floor heating type | Applicable scenarios | Advantages and Disadvantages |
|---|---|---|
| water floor heating | Large area, long-term use | Energy efficient but complex to install |
| Electric floor heating | Small area, temporary needs | Instant heating but high electricity bills |
3. Detailed explanation of transformation steps
1.Remove the original radiator: Close the valve and drain the pipe to avoid water leakage.
2.Laying insulation and reflective film: Reduce downward heat loss and improve energy efficiency.
3.Install floor heating pipes: Adopt "return-shaped" or "snake-shaped" coils, with a spacing of 15-20cm.
4.Connect the manifold: Ensure independent control of each circuit and balance water pressure.
5.Fill leveling layer: Cover pipes with cement or self-leveling material.
4. Answers to popular questions (search hot spots in the past 10 days)
Q1: Will the heating effect become worse after renovation?
A: No. Floor heating dissipates heat more evenly, but you need to ensure that the temperature of the heat source is suitable.
Q2: How much does it cost?
| Project | Estimated cost (yuan/㎡) |
|---|---|
| Water floor heating materials + construction | 80-150 |
| Electric floor heating materials + construction | 120-200 |
5. Things to note
1. Be sure to choose a professional construction team to avoid pipe leaks or insufficient thermal efficiency.
2. It is necessary to report to the property management before renovation, and private renovation may be prohibited in some communities.
3. Floor heating heats up slowly. It is recommended to turn it on for a long time in winter and is not suitable for intermittent use.
Through the above analysis, changing from central heating to floor heating requires comprehensive consideration of technology, cost and actual demand. With proper planning, floor heating can significantly improve home comfort, making it an ideal choice in cold winters.
