PEX or PERT? Which pipe for a warm floor to choose?

For your warm floor installation, selecting the appropriate piping system is essential to guaranteeing effective heating and long-term durability. PEX (cross-linked polyethylene) and PERT (polyethylene of raised temperature resistance) pipes are two of the most widely used options. Because each type has unique qualities and benefits, homeowners should carefully weigh their options before choosing one.

PEX pipes are well-known in the heating and plumbing sectors for their adaptability, sturdiness, and simplicity of installation. PEX pipes, which are made of cross-linked polyethylene and are suitable for a variety of applications, including radiant floor heating systems, can withstand high temperatures and pressures. Their adaptability makes it simpler to install them around corners and other obstructions, which eliminates the need for extra fittings and joints.

Conversely, PERT pipes are more resistant to high temperatures and provide advantages that are comparable to those of PEX pipes. Warm floor systems that expose their pipes to constant heat benefit greatly from the use of PERT, or polyethylene of raised temperature resistance, which is specially made to endure high temperatures. PERT pipes, which offer effective heat transfer and low heat loss, are flexible and simple to work with, much like PEX pipes.

There are a few things to consider when choosing between PEX and PERT pipes for your warm floor installation. Take into account your space’s particular heating needs, the installation area’s design, and any possible environmental influences that might have an impact on the piping system’s functionality. Examine each type of pipe’s availability and cost in addition to any local building codes or regulations that might affect your choice.

The decision between PEX and PERT pipes ultimately comes down to your personal tastes and the particulars of your heating project. Both varieties of pipes ensure effective heating and long-term satisfaction with your warm floor system by providing dependable performance and durability. You can choose a solution that fits both your heating needs and your budget by carefully weighing the benefits and drawbacks of each option.

When deciding between PEX and PERT pipes for your warm floor system, it"s crucial to consider factors like durability, flexibility, and cost-effectiveness. PEX pipes, made of cross-linked polyethylene, are popular for their strength and resistance to chemicals and high temperatures. They offer excellent performance and are widely used in heating systems. On the other hand, PERT pipes, made of raised temperature-resistant polyethylene, are newer to the market but gaining traction for their flexibility and ease of installation. While PEX pipes have a longer track record, PERT pipes may be a suitable choice for certain applications due to their flexibility and compatibility with low-temperature systems. Ultimately, the decision between PEX and PERT pipes depends on your specific needs, budget, and preferences, so it"s essential to weigh the pros and cons of each before making a choice for your warm floor system.

What pipes of the warm floor exist?

Metal -plastic pipes Construction and installation companies are now using quite rarely. Although the pipes have many pluses. The reason for this is a number of disadvantages. Firstly, during the installation process, the metal-plastic pipe can be “broken” and after that it is no longer subject to restoration. In addition, during construction, a situation may occur when the pipe is damaged by advancing or dropping various objects. If you do not keep track of this, then you will have a non -working contour. In fairness, it can be noted that it is not easy to damage this pipe, but when it happened, it is almost impossible to determine the place of the flaw.

Maintainability is the second disadvantage of the metal-plastic pipe. While it would take a lot to completely destroy the screed on both sides, it is impossible to repair the connections of these pipes, and there is no way to repair at the turn or loop location (the installers will know what we mean). The likelihood of recovery tends to be zero if there are multiple damages because the compounds mounted in metal-plastic reduce the diameter. As a result, the circuit will have an unacceptable level of hydraulic resistance but will continue to function normally.

PERT and PEX are the types of pipes that follow. The first is made of what is known as "higher heat resistance polyethylene." The second type of pipes are called PEX-A, PEX-B, and PEX-S depending on the production method. They are made of molecularly stitched polyethylene.

It will be challenging to select a pipe manufacturer because over thirty Russian and international manufacturers currently sell pipes. But, this won’t be a problem if you are aware of the features of these pipes.

Compare PEX and PERT

What then should you know about long-term operation (which, according to the manufacturer, should last at least fifty years and have properties similar to those of a warm water floor)? The aging graphs PERT and PEX below show that this process is nearly identical to a temperature of roughly 70 degrees Celsius (PEX is on the left, and pert is on the right).

Consequently, the pipe loses a significant amount of PEX at operating temperatures of 70 degrees or higher. Store consultants will state that PERT manufacturing technology pipes are associated with products that have higher heat resistance and can endure temperatures exceeding 110 degrees. It’s true that there has been a drastic decrease in the amount of time worked.

The pipe’s flexibility or stiffness can be taken into consideration next. This parameter is specific to a given manufacturer and is not dependent on the type of product. It should be noted that the same developer has a flexible and durable pipe, such as the PERT type. This regulation is relevant to the Pek variety. The ability to bend a pipe to the smallest possible radius without deforming is one of its properties known as stiffness.

By the way, this quality is important if you independently decide to install pipes due to the convenience of working with more supple material. But if you are a customer, then this property should not bother you at all. In this case, the whole difficulty of working with the product is laid on the shoulders of the installers. There is another nuance. Some installers make errors when installing, installing the pipe on the reinforcing mesh. They bend it very much and try to do it evenly, and not in the form of a loop or drop, and if a hard material is also used, the pipe is deformed, showing a cross -section in any other form, except for the shape of the circle, showing in the place of bending. This reduces the hydraulic indicators of the pipe loop and is reflected in the configuration of the circuit.

As of right now, there is no distinction between PEX and PERT pipe repairs. The advantage of polymer and brass fittings (the pipeline’s connecting sections) from their manufacturers over metal-plastic pipe is their extended service life.

The efficiency and lifespan of your heating system may be affected by your choice between PEX and PERT pipes for your warm floor system. Because each kind of pipe has advantages and disadvantages, it’s important to carefully consider your options.

PEX pipes are renowned for their pliability, toughness, and chemical and corrosion resistance. They are a popular option for both contractors and homeowners due to their comparatively simple installation. PEX pipes work well with radiant heating systems and hot water heaters because they can withstand high temperatures.

PERT pipes, on the other hand, are a good option for warm floor applications because of their superior thermal conductivity. They lessen the possibility of corrosion in your heating system because they are more resistant to oxygen penetration than PEX pipes. PERT pipes can be installed in confined spaces because of their extreme flexibility.

A few things to think about when choosing between PEX and PERT pipes are your budget, the particular needs of your heating system, and the climate where you live. PEX pipes might be a better choice if dependability and simplicity of installation are your main concerns. PERT pipes, however, might be the best option if increasing thermal efficiency and lowering the chance of corrosion are essential.

In the end, there isn’t a universal solution to the PEX vs. PERT controversy. Making the best decision for your warm floor system requires careful consideration of all of your options and advice from a trained expert. You can make sure your heating system runs effectively and efficiently for many years to come by doing this.
