With the end of the heating period, PEX Expansion Fittings reminds you to pay attention to closing the water divider and the main pipeline valve after the heating is over to prevent the hidden danger of water leakage.
First of all, it is necessary to clarify the necessity of floor heating maintenance. Good floor heating maintenance can eliminate possible hidden dangers and failures, improve the heating effect of floor heating, reduce operating energy consumption, improve the operating environment of pipelines and boilers, and extend the overall service life of floor heating. Closer to home, let’s talk about the maintenance after heating, taking the water floor heating systems and gas-fired water heaters that are currently used more frequently.
- Pipeline inspection
Due to thermal expansion and contraction, you need to check whether there is water leakage at the pipes and connections after the heating is stopped. If the heating is exposed, you can directly observe whether there is water leakage; if it is floor heating or concealed heating, you can judge by observing the pressure gauge .
The faster the pressure gauge value drops, the greater the problem. If there is a leak in the pipeline, the maintenance will be very troublesome. Specific reference can be made.
In principle, a qualified installation process will not cause interface leakage.
- Cleaning
1. Clean the filter
After exhausting the air, close the valve, open the filter of the floor heating system, take out the filter for cleaning, and check whether the filter is damaged or blocked.
If the filter is damaged, you must replace it with a new filter of the same specification and model, and install it as it is. Note that you must be careful when removing the filter to prevent debris from entering the tube.
- Pipeline cleaning
Many people think that the underfloor heating system is in a closed environment, no dust will enter, and no cleaning is needed. They don’t know that if they are not cleaned regularly, the pipeline will become a breeding ground for bacteria, and silt, rust, bacteria and algae will easily block the pipeline, which will seriously affect Heating effect. Commonly used methods of floor heating cleaning are: chemical cleaning, projectile cleaning, jet cleaning, physical pulse cleaning
Three, wall-hung boiler cleaning
Internal cleaning and descaling can effectively reduce the load of main components such as water pumps and heat exchangers, reduce the wear of running parts, and make the boiler run more smoothly. If the boiler is cleaned and maintained every one to two years, the service life of the equipment can be extended by 3-5 years. When using the floor heating washer, the water floor heating pipe and the wall-hung boiler can be cleaned together; while the heating pipe and the wall-hung boiler need to be cleaned separately. - Full water maintenance
Whether it is a central heating system or an independent heating system for a home wall-hung boiler; whether it is a steel radiator, a cast iron radiator or a copper-aluminum composite radiator, it should be fully maintained with water. Full water maintenance can isolate oxygen, reduce the oxygen content in the water, prevent oxygen corrosion, and extend the service life of floor heating and radiators.
Method: Inject water with protective agent into the cleaned pipe network and burn the boiler, heat the water in the system to 60℃, keep the temperature for 1～1.5h, and then pass the system exhaust valve that has been opened , The air separated from the water is discharged out of the system. After exhausting, close all the valves in the system, turn off the furnace, let the water cool down gradually, and keep the water in the pipe network of the system until the beginning of the next heating period.
Regardless of whether it is a boiler or a pipeline, the premise of the life promised by the Expansion PEX Plug manufacturer is normal maintenance. Good usage habits and regular maintenance are the long-term use of floor heating.
