electric radiant -floor heating system

Electric radiant floor heating, often referred to as a ‘dry system’, is renowned for its simplicity and efficiency. It operates through a network of electric heating mats (or cables), installed directly below the floor surface, ensuring a uniformly warm floor.

The mats are strategically designed to offer even heating across the floor. When powered by your home’s electricity, these floor mats promptly heat up, providing direct warmth to the floor above.

Heated floor mats provide the advantage of localized control. Rather than depending on a central heating source, users can regulate the temperature of individual rooms or areas, optimizing energy usage while maintaining comfort.

While traditionally heated floor mats were most favored for specific rooms, like bathrooms or kitchens, recent technological advancements now allow homeowners to consider heating their entire home with these radiant floor mat systems.


The installation of an electric radiant floor heating system in a new construction is relatively straightforward, especially when compared to its hydronic counterpart or retro-fitting projects. Here are the key steps involved:

  1. Floor Preparation: Begin by ensuring the subfloor is devoid of any debris. It should be clean, dry, and smooth. Remove any protrusions, like nails or staples, to prevent potential damage to the mats.
  2. Layout Planning: Draft a plan to lay out the mats. Avoid placing mats under permanent fixtures, such as cabinets, to ensure heat is evenly distributed in the desired areas.
  3. Positioning the Heated Mats: Unroll or position the mats according to the pre-planned layout. Ensure they fit well and cover the desired areas.
  4. Embedding the Mats: Secure the mats in place using a thin-set mortar or self-leveling compound. This layer ensures the mats have optimal contact with the floor, facilitating efficient heat transfer.
  5. Electrical Connections: Have a licensed electrician connect the mats to your home’s electrical system. This ensures safety, proper grounding, and the installation of a dedicated circuit for the mats.
  6. Thermostat Installation: Finally, a digital thermostat is installed to allow homeowners to regulate the system’s temperature and schedule heating cycles.

Pros and Cons



Impact of Flooring Types on Electric Radiant Floor Heating Installation

The type of flooring chosen plays a pivotal role in how an electric radiant floor heating system, especially heated floor mats, is installed and performs. 

Each flooring material has unique properties that influence heat transfer and installation techniques.

  • Ensure proper subfloor preparation, ensuring it’s free from moisture.
  • Use a thin-set layer or recommended adhesive to position the mats.
  • Take care not to exceed the manufacturer-recommended temperature; excessive heat can damage or warp the wood.

Tile & Stone

Tile and stone are among the most thermally conductive flooring materials. This makes them ideal candidates for radiant heating systems. 

When installing electric radiant heating under tile and stone:

  • A layer of thin-set adhesive is essential for embedding the heating mats.
  • The dense nature of tiles and stone ensures efficient heat transfer, warming up the floor quickly.

Laminate & Vinyl

Most modern laminate and vinyl flooring options have been designed to be compatible with radiant heating systems, so you needn’t worry about any issues with overheating.

When installing heated mats:

  • A layer of thin-set adhesive is essential for embedding the heating mats.
  • The dense nature of tiles and stone ensures efficient heat transfer, warming up the floor quickly.


Carpet acts as an insulator, which can hinder the efficiency of radiant floor heating. However, with the right installation technique, it can work just as effectively as with any other type of floor.

When installing heated mats:

  • Opt for a thin carpet and padding to ensure optimal heat transfer.
  • Heated mats should be fully embedded in a self-leveling compound to ensure even heat distribution.


Concrete floors can directly embed heating mats, making them highly efficient in terms of heat retention and distribution.

When installing electric radiant heated mats under concrete:

  • During installation, the mats can be positioned within the concrete as it’s laid.
  • Concrete’s thermal mass retains heat for extended periods, making it energy efficient.
  • Add insulation to maximize energy efficiency and cost savings.

Hydronic Radiant Floor Heating Systems

hybrid radiant floor heating

Hydronic radiant floor heating is considered the most popular and cost-effective among radiant heating solutions, especially for larger areas or new build properties. 

Commonly termed a ‘wet system’, it functions using a series of flexible polyethylene tubes that run beneath the flooring. These tubes circulate warm water, which is heated by a furnace, thus radiating heat upwards.

The real beauty of the hydronic system lies in its adaptability. It can be paired with various heat sources, from conventional gas or oil boilers to more sustainable alternatives like solar water heaters or geothermal systems. 

This adaptability not only ensures consistent warmth but also offers homeowners the flexibility to switch energy sources without overhauling the entire system. Plus, with its capability to maintain heat for longer durations, it operates in shorter cycles compared to its electric counterpart, leading to potential energy savings. 

This makes it particularly suitable for new constructions that plan to incorporate multiple, complimentary heating solutions.


Hydronic systems are more involved in their installation due to the plumbing intricacies:

  1. Subfloor Preparation: A clean, flat surface is vital to ensure the proper layout of the tubing and prevent any damage or leaks.
  2. Mapping the Tubing Route: Before the installation, a detailed plan is drawn up, accounting for the tubing’s circuitous pattern and ensuring even heat distribution.
  3. Installing the Tubes: The flexible polyethylene tubes are carefully laid out on the subfloor according to the plan, often secured using staples or ties.
  4. Manifold Connection: Once the tubes are in place, they’re connected to a central manifold, which acts as the control center, distributing hot water from the boiler to the various tubes and returning cooled water back to the heating source.
  5. Laying the Floor: Over the tubes, a layer of screed or concrete is poured, which not only secures the tubes in place but also aids in the even distribution of heat.
  6. Boiler and Pump Connection: The system’s heart is the boiler, which heats the water. This is connected to the manifold, and a pump is installed to ensure the continuous circulation of water.
