How to distinguish between good and bad floor heating pipes
As winter approaches, floor heating systems have become the first choice for heating many homes. As the core component of the floor heating system, the quality of floor heating pipes directly affects the heating effect and service life. So, how to distinguish the quality of floor heating pipes? This article will give you a detailed analysis from multiple dimensions such as material, performance, brand, etc.
1. Main materials and characteristics of floor heating pipes
The material of the floor heating pipe determines its high temperature resistance, pressure resistance and corrosion resistance. Common floor heating pipe materials currently on the market include the following:
| Material type | Features | Applicable scenarios |
|---|---|---|
| PEX (cross-linked polyethylene) | High temperature resistance, strong pressure resistance, good flexibility, not easy to scale | Household and commercial floor heating |
| PERT (high temperature resistant polyethylene) | Excellent high temperature resistance, moderate price, easy to process | Ordinary home floor heating |
| PB (polybutylene) | High temperature resistance and corrosion resistance, but the price is higher | High-end floor heating system |
| Aluminum plastic composite pipe | High strength, resistant to oxygen penetration, but complicated to install | Floor heating system requiring high stability |
2. How to identify the quality of floor heating pipes
1.Look at the appearance: High-quality floor heating pipes have a smooth surface without bubbles, impurities or obvious color differences. Inferior quality pipes may have problems such as roughness and uneven color.
2.Measuring flexibility: A good floor heating pipe has good flexibility and is not easy to break. You can try bending the pipe to see if there are any cracks or deformations.
3.Check pressure resistance: High-quality floor heating pipes can withstand higher pressures and are usually marked with a pressure rating (such as 1.0MPa or above). Its pressure-bearing capacity can be tested with professional equipment.
4.smell: Inferior floor heating pipes may contain harmful substances and smell like pungent plastic. High-quality pipe is usually odorless or has only a slight plastic smell.
5.View certification mark: Regular brands of floor heating pipes will have national certification marks (such as GB/T standards), and some high-end products also have international certifications (such as ISO9001).
3. Recommended brands of floor heating pipes
There are many brands of floor heating pipes on the market. Here are a few brands with good reputations and their characteristics:
| brand | Features | price range |
|---|---|---|
| Rifeng | Well-known domestic brand, PEX pipe technology is mature and cost-effective | medium |
| great star | Stable quality and perfect after-sales service | Mid- to high-end |
| Kinder | Representative of high-end floor heating pipes, PB pipes have excellent performance | High-end |
| George Fisher | International brand, leading technology, but higher price | high-end |
4. Precautions for installation and maintenance of floor heating pipes
1.Check before installation: Ensure that the pipes are not damaged and the construction is carried out in strict accordance with the design drawings.
2.Avoid high temperature exposure: Uninstalled floor heating pipes should be stored in a cool place to avoid aging caused by direct sunlight.
3.Clean regularly: The floor heating system should be professionally cleaned after 2-3 years of use to prevent pipe blockage.
4.Pay attention to water temperature control: The floor heating water temperature should not exceed 60°C, otherwise the pipe life may be shortened.
Summary
Choosing high-quality floor heating pipes is the key to ensuring long-term and stable operation of the floor heating system. By comparing materials, appearance, brands and other aspects, you can easily distinguish the quality of floor heating pipes from bad ones. It is recommended to give priority to well-known brands and pay attention to installation and maintenance to extend the service life of the floor heating system.
