Underfloor Heating Mat Systems VS Underfloor Heating Cable Systems

Underfloor heating is becoming increasingly popular as an efficient and comfortable way to heat homes. Two primary types of electric floor heating systems are mat systems and cable systems. Both have their own unique benefits and considerations, making them suitable for different applications.

In this post we explore the important differences between underfloor heating mat systems vs underfloor heating cable systems, helping you make an informed decision for your home heating needs.

What Are Underfloor Heating Mat Systems?

Underfloor heating mat systems consist of a pre-spaced cable that is attached to a mesh mat. These electric floor heating mats are designed to be rolled out over the floor area that needs heating, making installation relatively straightforward. The mesh can be cut and rotated to fit the specific shape of the room, providing even coverage.

Mat systems are particularly suitable for regular-shaped rooms with a consistent layout, such as living rooms, basements and dining rooms. They are often used in renovations and retrofits because they can be installed directly on top of existing floors, provided there is adequate insulation.

Advantages of Underfloor Heating Mat Systems

One of the primary advantages of mat systems is their ease of installation. The pre-spaced cables on mesh mean that there is no need to worry about maintaining consistent spacing between the cables, simplifying the installation process. This can save time and reduce the potential for installation errors.

Mat systems also provide even heat distribution, so that the entire floor area is heated uniformly. This can contribute to a more comfortable living environment, with no cold spots on the floor.

What Are Underfloor Heating Cable Systems?

Underfloor heating cable systems consist of a cable on a spool which is laid out across the floor. The cables are secured at 3” spacings using fixing strips or a similar method to ensure they remain in place during the installation process.

This type of system allows for greater flexibility in terms of spacing and layout, making it suitable for irregularly shaped rooms or areas with complex layouts, example bathrooms, kitchens and smaller spaces.

Cable systems are often used in new construction projects or major renovations where the floor is being completely redone. They can be embedded in a layer of screed, providing an effective and durable heating solution.

Advantages of Underfloor Heating Cable Systems

One of the main advantages of cable systems is their flexibility. Because the cables are not pre-attached to a mat, they can be spaced as needed to accommodate the specific heating requirements of the room. This makes cable systems ideal for rooms with unusual shapes or obstacles, where a more customized heating solution is necessary.

Cable can also be place at 2.5” spacings providing a slightly higher heat output when compared to the standard 3” mat spacings. This makes them suitable for areas that require more intensive heating, such as larger rooms or spaces with higher heat loss.

Underfloor heating cable systems can be more affordable in terms of materials, especially for larger areas. The loose cables are typically less expensive than the pre-spaced mats, which can be a consideration for budget-conscious projects.

Installation Considerations

The installation process for both mat and cable systems requires careful planning and preparation. For mat systems, the primary consideration is checking that the mats are cut, rotated and laid out correctly to cover the entire floor area without overlapping. The mats must also be secured properly to prevent any movement during the installation of the floor covering.

For cable systems, the installation process involves laying out the cables according to the desired spacing and securing them in place. This can be more time-consuming than installing mat systems, but it allows for greater customization. It's essential to follow the manufacturer's guidelines to ensure the cables are installed correctly and safely.

In both cases, proper insulation is needed to maximize the efficiency of the underfloor heating system. Insulation boards can be installed beneath the heating mats or cables to reduce heat loss and improve the overall performance of the system.

Final Thoughts

Choosing between underfloor heating mat systems and cable systems depends on various factors, including the size and shape of the room, the type of project, budget considerations, and specific heating requirements.

Mat systems offer quick easy installation and uniform heat distribution, making them ideal for larger more regular-shaped rooms. Cable systems also provide uniform heat when correctly spaced, however, they provide greater flexibility, and if needed, a higher heat output, cables are often more suited for irregularly shaped areas.

By understanding the differences and advantages of each system, you can make an informed decision that best suits your needs, ensuring a warm and comfortable living space.
