How to judge the quality of floor heating pipes

How to judge the quality of floor heating pipes: comprehensive analysis of purchasing and identification skills

With the arrival of winter, floor heating is an important way of home heating. The quality of its core component, the floor heating pipe, is directly related to the heating effect and service life. This article will combine the hot topics and user concerns on the Internet in the past 10 days to analyze how to judge the quality of floor heating pipes from multiple dimensions such as material, performance, brand, etc.

1. Comparison of core materials and performance of floor heating pipes

The main materials of floor heating pipes include PEX (cross-linked polyethylene), PERT (high temperature resistant polyethylene) and PB (polybutylene). The characteristics of different materials are as follows:

2. Six key indicators to identify the quality of floor heating pipes

1.Appearance inspection: High-quality floor heating pipes have a smooth surface without bubbles and uniform wall thickness; inferior pipes may have color differences or unevenness.

2.Flexibility test: Bend the pipe 180 degrees, and the high-quality pipe will have no white marks or cracks.

3.Translucency experiment: When exposed to strong light, tubes with poor light transmittance (good oxygen barrier properties) are more resistant to aging.

4.Brand certification: Check whether there are international certifications such as ISO9001 and CE, as well as the warranty period (high-quality pipes usually have a 50-year warranty).

5.Burn test: Qualified PE materials have no black smoke and a waxy smell when burning; adulterated pipes will produce a pungent smell.

6.Professional test report: Require merchants to provide pressure and high temperature resistance test reports from third-party institutions.

4. Installation precautions and pit avoidance guide

1.Pipe spacing: It is recommended to use 15-20cm in the north and 20-25cm in the south. Edge areas such as balconies need to be dense.

2.Water distributor selection: Copper water distributor is better than stainless steel, and the length difference of each circuit should not exceed 15%.

3.stress test: After installation, a 0.8MPa pressure holding test must be carried out, and the pressure drop shall not exceed 0.05MPa in 24 hours.

4.Common pitfalls: Be wary of behaviors such as substituting pipe brands in "low-price packages" and using PEX-B as PEX-A.

5. Answers to the 5 questions that users are most concerned about

Q1: Do floor heating pipes need to be replaced regularly?
A: High-quality pipelines have a design life of 50 years and do not need to be replaced regularly. However, it is recommended that a system inspection be performed every 5 years.

Q2: Which color pipe is better?
A: Color has nothing to do with quality. White/red are mostly PERT tubes, and gray/orange are mostly PEX tubes.

Q3: How to judge the authenticity of the oxygen barrier layer?
A: The real EVOH oxygen barrier layer is translucent and will not fall off when gently scraped with a blade.

Q4: How to quickly locate floor heating leaks?
A: If you use an infrared thermal imaging camera or a professional leak detector, the temperature at the leak point will rise abnormally.

Q5: Do I need to replace the floor heating pipes when renovating a second-hand house?
A: It is necessary to evaluate the service life and pressure test results of the original pipeline. It is recommended to replace it if it is more than 10 years old.

Through the above system analysis, consumers can ensure the quality of floor heating pipes from many aspects such as material selection, brand comparison, and installation supervision. It is recommended to give priority to brands that provide "pipeline insurance" services, such as Rifeng Pipe's "Safety Guard" service, which provides double protection for the heating system.
