In modern home decoration, underfloor heating has become the choice of many families. Underfloor heating systems not only provide a comfortable indoor temperature, but also save space and improve living comfort. However, in the installation process of the underfloor heating system, the pressure test is a very important part. So, when decorating floor heating, is it better to use water or gas to suppress?This article will examine this issue from different perspectives.
First of all, we need to understand what a repression test is. The pressure test refers to the injection of water or gas at a certain pressure into the pipe after the installation of the floor heating system is completed to check whether the pipe has water leakage, damage and other problems. This is a very important step, because once there is a problem such as water leakage in the floor heating system, it will not only affect the use of floor heating, but also may cause damage to the structure of the house.
Next, let's compare the advantages and disadvantages of water pressure and gas pressure.
1.Suppress with water.
Advantages: 1) The water pressure is stable and easy to control. Due to the greater density of water, the impact force of water on the pipe is less than that of gas at the same pressure. This helps to protect the underfloor heating pipes and reduce the damage caused by pressure tests.
2) Low cost. No additional equipment is required for water pressing, just the use of a water pump. However, gas suppression requires the purchase of special compressors and gases, which is costly.
3) High security. Water is harmless, and even if there is a leak in the underfloor heating pipes, it will not cause harm to the environment and the human body. However, if the gas leaks during gas suppression, it may cause safety accidents such as fires.
Disadvantages: 1) The water pressure is low. Since water is less compressible, a higher pressure is required to achieve the desired effect when pressed with water. This may increase the difficulty and time of the suppression test.
2) The water pressure is unstable. Water pressure may fluctuate due to changes in the temperature of the water and the ambient temperature. This may affect the accuracy of the suppression test.
2.Suppress with gas.
Advantages: 1) High pressure. Due to the high compressibility of gas, it is easy to achieve high pressures when pressed with gas. This helps to identify problems with underfloor heating pipes more quickly.
2) Stable pressure. The pressure of the gas is less affected by temperature and environment, so the pressure is more stable when pressed with gas. This is beneficial to improve the accuracy of the suppression test.
Disadvantages: 1) High cost. Gas suppression requires the purchase of special compressors and gases, which is costly.
2) Less secure. Although the gas itself is harmless, if the gas leaks, it can cause safety accidents such as fires. In addition, if the pressure is too high when using gas, it may cause the underfloor heating pipe to burst, causing serious damage.
After comparing the advantages and disadvantages of water pressure and gas pressure, we can draw a conclusion: when choosing a floor heating pressure method, it needs to be weighed according to the specific situation. Here are a few suggestions for your reference:
1.From a cost perspective: If you have a high budget requirements, then water pressure may be a better option. Because water pressing does not require the purchase of additional equipment, the cost is relatively low. However, gas suppression requires the purchase of compressors and gases, which is costly.
2.From a safety perspective: If you take safety very seriously, then water pressure may be more suitable for you. Because water is harmless, even if there is a leak in the underfloor heating pipes, it will not cause harm to the environment and the human body. However, if the gas leaks during gas suppression, it may cause safety accidents such as fires.
3.From the perspective of suppression effect: If you want the pressure test to be more accurate in finding problems with underfloor heating pipes, then air pressure may be more appropriate. Because the pressure of the gas is less affected by temperature and environment, the pressure is more stable. This is beneficial to improve the accuracy of the suppression test.
4.From a practical point of view: If you want to be able to carry out underfloor heating pressure tests more easily, then water pressure may be more suitable for you. Because no additional equipment is required for water pressing, the operation is relatively simple. However, gas suppression requires the purchase of compressors and gases, and the operation is relatively complicated.
In short, when choosing a way to suppress underfloor heating, you need to weigh it according to your actual needs and budget. On the premise of ensuring safety, choose an economical and practical suppression method to ensure the installation quality and use effect of the floor heating system. At the same time, it is recommended that when you conduct the floor heating pressure test, it is best to consult a professional installation master or floor heating company to ensure the smooth progress of the pressure test and the accuracy of the results.
