Instructions on how to put back the pipes of warm floor with air, water

Comfort and energy efficiency depend on keeping your house warm and comfortable all year round. An efficient method for accomplishing this is by using a radiant floor heating system. These systems, which can be powered by air or water, evenly distribute heat across the floor to create a cozy warmth that gradually rises throughout the space.

But over time, problems with radiant floor heating can arise just like with any other system. It may be time to inspect and possibly fix your warm floor pipes if you’ve noticed any cold spots or uneven heating in your house. Fortunately, with the correct advice and equipment, replacing pipes for both air- and water-based systems can be done safely.

We’ll walk you through the process of identifying and resolving common issues with your warm floor pipes in this guide. Knowing the fundamentals of how air or water-based systems operate and how to troubleshoot them can help you avoid spending time and money on expensive professional repairs.

It’s important to understand the type of radiant floor heating system you have before beginning any repairs. Whereas water-based systems depend on a network of pipes to deliver hot water, air-based systems use a network of tubes to move warm air beneath the floor. The precise steps you need to take for troubleshooting will depend on which type you have.

We’ll walk you through step-by-step instructions in our guide on reinstalling underfloor heating pipes with either air or water systems to make sure your house stays warm effectively. Whether you’re working with water or air pipes, the procedure calls for meticulous planning, accurate measurements, and close attention to detail. Everything will be covered, including subfloor preparation, proper pipe laying, and system testing for peak efficiency. You can confidently restore your underfloor heating system and maintain comfort and energy savings for many years to come by adhering to our simple instructions.

Why should the warm floor need a warm floor?

The heating system will be tested, with the fitting connections and pipe tightness under high pressure examined. Testing enables you to find other flaws and leaks. Examine every heating circuit on its own.

Before laying the finish coating and pouring the concrete screed, the underfloor heating is crimped to make it easier to fix any flaws that may be found.

Before the pipes are sealed with GVL sheets, the hydraulic field should also be tested if it is installed in a wooden house in a "dry" manner.

Types of compressors, which

Warm water floor tests are conducted using both manual and electric compressors.

Pumping water or air into the pipeline highway is their primary duty. A pressure gauge is used to simultaneously control the unit’s operation.

Electric

Although they cost more and are bulkier, electric compressors are fully automated. There is absolutely no effort required on your part when using them. A hydraulic pump makes it simple to raise the system’s pressure to any desired level. Professionals use these devices more frequently and in larger quantities when pressure testing is necessary.

Even though these pumps are expensive, their higher performance level becomes a big benefit because they have an engine, which allows for time and effort savings.

Which to choose?

The following factors need to be considered when selecting the type of pump for crimping:

• heating system volume;
• The frequency of assessment work.

A hand compressor is a very good option if you need to make a small-scale system illegal; purchasing an expensive electric device is not necessary.

It is preferable to purchase an electric compressor pump because the power of this equipment might not be sufficient to check the heating system in a large room.

Think about the procedure step-by-step:

1. On the collector node are the return taps.

1. The pressure is set at 2.5 atmospheres.

1. The highway is filled with water through the supply pipes. At the same time, a hiss is present, which indicates an air exit from the Maevsky crane or through the air vent.

1. One return valve opens to lower air. Когда потечёт вода, значит, все воздушные пробки вышли, вентиль можно закрыть. Such actions must be carried out with all contours.

As a result of the voids created by air in the pipeline, the system’s efficiency is decreased because the pressure drops.

1. The crane is closed in front of the supply crest and opens before the return.

It is crucial to raise the coolant’s temperature gradually during hydraulic tests. The initial setting is +20 degrees, and 5 degrees are added every few hours. At this point, you should look for leaks on the warm floor. If leaks are found, the highway’s water supply should be drained in order to fix the problem.

After filling the pipeline with water once more, it is left for two to three days to undergo additional testing and observation in order to spot any potential issues.

The coolant’s degree of heating is gradually decreased if there are no more flaws. only filling the screed after the system has cooled.

Statement by cold water

When testing a warm hydraulic field with a cold coolant, higher pressure should be present. Chilled water must be pumped into the pipeline at a pressure that is twice as high. Two days of testing the system is sufficient to find bugs.

1. The pressure above the worker is set 2 times (4 – 5 atm). This is done by a compressor or using a car pump. To carry out air pumping devices, a hose is required, which is connected by a fitting and a crane.

1. The pressure is pumped only in the outline of the floor heating. It should not be on the site between the collector group and the boiler, since most of the heating devices withstand pressure up to 3 atm, otherwise they can reach their construction. Therefore, crimping the segment from the collector to the boiler must be done separately.
2. After filling the highway by air, the feed is closed, the structure is left for the day. At the same time, it is necessary to observe the level of pressure in the system. A small fall is permissible.

1. If the pressure drops, then the places that have poor tightness are determined. For this, areas where leakage is possible are covered with soapy liquid. For this, a liquid for cleaning glass or soap water is suitable. In places where air exits from the pipeline, the liquid will foam.
2. Problems are eliminated and crimping is repeated.

Fill the screed only after confirming that the heating system is error-free.

It is important to keep in mind that there is a concern that the pipeline may burst out of its seats when hydropolis is tested under extreme pressure. This might occur if the mounting tape was used for fixation.

In order to prevent this, mortar beacons must be installed prior to testing, and once they harden, they will form a frame that will secure the pipeline. There is no need for this procedure if the pipes are fixed to the metal grid.

What way to choose?

A common query is: Which testing method is most appropriate for warm water floors? The air method is more practical because it can’t always be turned on in time for the upcoming cold weather, which increases the risk of the pipeline freezing completely.

Air crimping prevents these kinds of issues. This is crucial for floor heating because it is challenging to drain the coolant from the floor circuits and is easily accomplished from the batteries.

However, when using an air method, it can be challenging to see if a connection is not sealed or if there is a pipe segment where air will escape. Water won’t cause any issues of this kind, and you’ll know where to go right away.

The kind of pipes used to heat water should also be considered when selecting a testing technique for the heating system.

Features of a hydraulic test depending on the type of pipes

Different kinds of pipes can be used to install water floor heating:

1. Metal -plastic pipes. When constructing warm hydropolis from metal -plastic pipes, it is recommended to put testing by injection of cold water. In this case, the maximum allowable pressure should be 6 bar. Testing is carried out within one day.

Keep in mind that filling is only done if there is pressure in the system. If the pressure stays the same, then everything is normal and you can move forward with building the screed. Additionally, the air vents need to be tightened if the check is performed at a pressure higher than 4 bar because otherwise, water could get through them.

1. The pipeline made of stitched polyethylene is produced using modern technology that allows you to sew molecules transversely. With a test with such a pipeline, increased pressure is created (at least 6 bar). After 30 minutes, if the pressure drops, it must be restored, and the system is tested for another thirty minutes. Then the procedure must be repeated, the warm floor should work in this mode for another 24 hours. If, after this period, the pressure decreased by a maximum of 1.5 bar, then it is believed that the testing has passed successfully.

It so happens that testing with hot coolant is advised following the cold water test. In this instance, it will take a few days to inspect every joint and connection. You can fill in a screed once the system cools down if the pressure level is normal.

To keep your house cozy and energy-efficient, make sure your warm floor system is working properly. Achieving the best possible heating performance requires proper installation, whether you’re working with water or air pipes. Reinstalling the pipes in your warm floor system can be done with confidence if you follow the instructions in this guide.

It is imperative that you become acquainted with the particular kind of warm floor system you own first and foremost. Knowing its parts and how they function together will make reinstalling it easier for you, whether it’s a water- or air-based system. Spend some time going over any manuals or documentation that the manufacturer may have sent you to make sure you fully comprehend your system.

Next, the secret to a successful reinstallation is preparation. It’s important to remember to clear the space where the pipes will be installed and make sure the right insulation is in place. Furthermore, it’s crucial to examine the pipes themselves again for any indications of wear or damage in order to avoid further problems with your system.

A meticulous approach is essential when it comes to reinstalling your warm floor system’s pipes. To guarantee uniform heating throughout the room, make sure you adhere to the manufacturer’s recommendations regarding pipe spacing and arrangement. Ensuring that the pipes are securely fastened and implementing any necessary modifications along the way will contribute to dependable system performance.

Ultimately, extensive testing is necessary to make sure everything is operating as it should after the pipes have been replaced. You can handle any issues as soon as they arise by running the system and looking for any leaks, uneven heating, or other problems. You can continue to save money on energy and have consistent comfort for many years to come if you take the time to test and reinstall your warm floor system correctly.
