If you’ve ever tiptoed across a freezing bathroom tile floor on a winter morning, you’ve probably dreamed of warm floors that greet your feet like a cozy blanket. At Expert Electric, we specialize in making that dream a reality. Knowing how to install in-floor heating can help homeowners enjoy improved comfort, energy efficiency, and long-term value. Whether you’re building a new home or renovating your current one, this guide is designed to walk you through everything you need to know about installing electric in-floor heating.
What is In-Floor Heating?
In-floor heating, also known as radiant floor heating, is a system that warms your home from the ground up by distributing heat beneath your flooring. Unlike forced-air systems that blow hot air into a room, in-floor heating emits radiant heat that rises naturally. This means no cold spots, no noisy vents, and better indoor air quality.
There are several types of radiant heating systems, but the most common and energy-efficient for residential homes is electric in-floor heating. It’s especially effective in high-traffic and tiled areas like kitchens, bathrooms, and entryways.
Benefits of In-Floor Heating
Wondering if in-floor heating is worth the investment? Let’s break down the advantages:
1. Energy Efficiency
Electric in-floor heating systems operate at lower temperatures than traditional forced-air systems, which reduces electricity use. The heat is evenly distributed, so you don’t waste energy heating unused areas of a room.
2. Increased Comfort
Forget about shivering toes or cold tiles. Heated floors deliver consistent, even warmth. The days of waking up to chilly feet are over.
3. Space-Saving Design
There are no vents, ducts, or baseboards involved. This gives you complete freedom over your furniture layout and room aesthetics.
4. Quiet Operation
No fans, no blowing air, just silent, efficient warmth.
5. Low Maintenance
Electric in-floor heating systems have fewer moving parts and typically require less maintenance compared to boilers or HVAC systems.
Types of In-Floor Heating
When considering how to install in-floor heating, it’s crucial to understand the different system types:
1. Electric Radiant Floor Heating
This system uses cables or mats embedded beneath your floor. It’s ideal for retrofits and small areas like bathrooms or kitchens.
2. Hydronic Radiant Floor Heating
These use hot water pipes installed under the floor, powered by a boiler. More common in new builds due to their complex installation and higher initial costs.
3. Radiant Air Floors
Less common, these use heated air ducts beneath the floor and are generally less efficient than other types.
At Expert Electric, we specialize in electric radiant floor heating, the most energy-efficient and practical option for most homeowners.

How to Install In-Floor Heating: A Step-by-Step Process
Let’s dive into the process of how to install in-floor heating using electric radiant systems:
Step 1: Remove the Existing Flooring
Before installation begins, you need to completely remove the existing flooring. This might include tile, laminate, carpet, or hardwood. Some flooring types can be reused if removed carefully, but others—especially tiles, often require replacement.
Pro Tip: Use this as an opportunity to update your home’s flooring with heat-compatible materials such as ceramic or porcelain tile, engineered wood, or luxury vinyl.
Step 2: Assess and Prepare the Electrical System
Next, a licensed electrician will:
- Locate a nearby GFCI-protected power source or create a dedicated circuit on the electrical panel.
- Assess the circuit load capacity to ensure it can handle the heating system.
- Route the power cable and thermostat sensor wire through the wall to where the thermostat will be installed.
At Expert Electric, we ensure this step complies with all Canadian Electrical Code requirements.
Step 3: Order or Measure for a Custom-Fit Heat Mat
Your installer will measure the space and either purchase a pre-sized heating mat or order a custom-fit version. Heating mats are pre-wired for simplicity and can be cut (not the wires, just the mesh) to fit around fixtures and corners.
This guarantees full coverage of your floor, eliminating cold patches and boosting energy efficiency.
Step 4: Lay Down and Secure the Heating Mat
The heat mat is laid out carefully across the subfloor. The installer will:
- Dry-fit the mat to ensure it fits the space.
- Apply thin-set mortar or adhesive to bond the mat to the subfloor.
- Avoid overlapping wires to prevent uneven heating or electrical hazards.
Once secured, your radiant heat system is almost ready for wiring.
Step 5: Connect to the Thermostat and House Circuit
The mat is then wired into your thermostat and electrical system. A licensed electrician will:
- Connect the cold lead wires to the thermostat and circuit.
- Test the system using a multimeter for continuity and resistance.
- Program the thermostat to your desired settings.
At Expert Electric, our team performs thorough inspections to ensure everything runs safely and efficiently.
Step 6: Reinstall the Flooring
Finally, new flooring is installed over the radiant heat system. Popular choices include:
- Tile: Excellent heat conduction and durability.
- Engineered Hardwood: Must be rated for radiant heat.
- Luxury Vinyl Tile (LVT): A budget-friendly, heat-compatible option.
Make sure to follow the flooring manufacturer’s guidelines for radiant heating compatibility.
How Much Does In-Floor Heating Cost?
Installing electric in-floor heating typically costs between $10 to $20 per square foot, depending on the room size, materials, and labor. Smaller spaces like bathrooms are more affordable to retrofit. Larger or whole-home projects will have higher costs but deliver more consistent heating.
At Expert Electric, we provide transparent quotes and personalized recommendations to match your needs and budget.
Safety Considerations and Professional Help
Installing in-floor heating involves high-voltage electrical work and must comply with strict safety standards. DIY installations often lead to:
- Tripped breakers
- Fire hazards
- Damaged heating mats
- Inefficient operation
Always hire a licensed electrician like the ones at Expert Electric to ensure your system is installed properly and safely.

FAQs About In-Floor Heating
Q: How long does electric in-floor heating last?
A: With proper installation, systems can last 20–30 years or more. Thermostats and sensors may need replacement sooner.
Q: Can I install in-floor heating under hardwood?
A: Yes, but the wood must be engineered and rated for radiant heat. Solid hardwood may warp due to temperature changes.
Q: Is in-floor heating energy efficient?
A: Absolutely. It offers better heat retention and lower operating temperatures than forced-air systems, resulting in lower energy bills over time.
Q: What’s the best type of flooring to pair with radiant heating?
A: Tile and stone are the most efficient. Vinyl and engineered wood are also suitable if heat-rated.
Q: Does in-floor heating work with smart thermostats?
A: Yes! Many radiant floor systems are compatible with Wi-Fi-enabled smart thermostats for remote control and scheduling.
Final Thought: Invest in Year-Round Comfort
