The Ultimate Guide to Underfloor Heating Mats: Construction, Installation, and Benefits
Introduction
Underfloor heating mats are a modern and efficient way to heat your home, providing comfortable warmth while saving space and energy. These mats consist of heating cables attached to a mesh or mat, which are installed beneath the floor surface to provide radiant heat evenly throughout the room.
Underfloor heating mats are more comfortable than any other type of heating system. Radiant heating through the underfloor heating mat is the most energy-efficient way of delivering heat. There is no other floor heating option that compares in terms of comfort because it warms the people and items directly rather than heating air. In most circumstances, radiant floor heating mats may save 20 to 40% of energy compared to other forms of heating systems. With a digital thermostat, these are completely customizable for maximum comfort and efficiency. The thermostat regulates the heating mat to provide optimal economic functioning of the floor heating, not the W/m² of the heating mat, which determines energy usage.

Benefits of Underfloor Heating Mats
- Even Heat Distribution: Underfloor heating mats distribute heat more evenly compared to traditional radiators, eliminating cold spots and providing consistent warmth.
- Space-Saving: By installing heating mats under your floors, you can free up wall space that would have been occupied by radiators, giving you more design flexibility. Works quietly from beneath the tiles/plywood.
- Energy Efficiency: Underfloor heating mats operate at lower temperatures than traditional heating systems, resulting in lower energy consumption and reduced heating costs. Easy to control the required temperature in all weather by a digital temperature controller with thermostat.
- Improved Comfort: Walking on warm floors during cold weather can significantly enhance the comfort of your home.
- Easy installation and can be installed in any area in the house and on any type of flooring.
- Can be an excellent option for low-energy homes.
- For optimal protection, Marathon floor heating mats are insulated using XPLE/ETFE/FEP/PTFE on both the conductors and PVC (HR-FR) on the outer jacket.
- Marathon floor heating mats have been developed particularly to deliver primary heating beneath a variety of flooring. To facilitate ‘tape-down’ installation, the mats are also available in the preassembled fiberglass mats.
- Marathon floor heating mats are completely grounded and come with a 3.5-meter-long cold lead wire for power connection.
Installation Process of Underfloor Heating Mats
Step 1: Planning and Preparation
- Measure the room to determine the required heating mat size.
- Ensure the subfloor is clean, dry, and level before installation.
- Remove any trash and sharp protrusions from the subfloor.
- Prior to installation, consider deflection and structural factors.
Step 2: Installation Guidelines
- Lay the underfloor heating mats according to the manufacturer’s instructions, ensuring proper spacing between the heating cables.
- Prior to putting down floor coverings, consider using a scratch coat or a thin leveler.
- Install a heat-resistant insulation sheet if you want to reduce heat loss (optional).
- Secure the mats in place using adhesive or fixing tape.
- Install the marathon floor heating mat according to the manufacturer’s installation directions.
Step 3: Wiring and Controls
- Connect the heating mats to a thermostat for sensing the floor and power supply according to the manufacturer’s guidelines.
- Test the system to ensure it is functioning properly before covering it with the final flooring.
