Can You Use LVT or SPC Flooring with Underfloor Heating?

Underfloor heating is becoming a preferred solution for homeowners looking for energy-efficient, discreet warmth throughout the home. At the same time, luxury vinyl flooring—specifically LVT (Luxury Vinyl Tile) and SPC (Stone Plastic Composite)—is gaining popularity for its durability, waterproof nature, and stylish finishes. But many people still wonder: Can LVT or SPC flooring be used with underfloor heating?

The good news is yes—both LVT and SPC flooring are suitable for use with underfloor heating systems. However, to enjoy long-term comfort and performance, there are a few essential guidelines and limitations you should understand before installation. This guide will walk you through everything you need to know, including the types of systems that are compatible, proper installation methods, and key mistakes to avoid.

LVT and SPC: What Makes Them UFH-Friendly

LVT (Luxury Vinyl Tile) and SPC (Stone Plastic Composite) flooring are excellent choices for pairing with underfloor heating due to their material structure. Both flooring types are engineered with thin, dense cores that allow heat to transfer efficiently to the surface, making your room feel warm quickly and evenly.

SPC flooring is made with a rigid limestone composite core, giving it excellent thermal conductivity and dimensional stability—even in rooms where temperature fluctuates. LVT, on the other hand, is slightly more flexible but still highly effective when installed correctly with underfloor heating systems.

Low thermal resistance: Enables quicker heat transfer compared to traditional floor types.
Stable construction: Resists warping or gapping under gentle heating cycles.
Thin profile: Allows heat to pass through faster than thicker flooring types like solid hardwood.

Because of these characteristics, LVT and SPC flooring are ideal for homes where both comfort and modern efficiency are priorities.

Important Factors to Consider

While LVT and SPC flooring are compatible with underfloor heating, several technical requirements must be followed to ensure optimal performance and avoid damage. These factors will help maintain the longevity of both your flooring and heating system.

Maximum temperature: The surface temperature of the floor should not exceed 27°C. Exceeding this can cause warping or delamination of the floorboards.
Even heat distribution: Avoid using thick rugs or furniture that restrict heat flow in certain areas, as this can lead to hot spots and material stress.
Correct product thickness: LVT and SPC floors generally range from 4mm to 6.5mm. Thinner options allow for better heat transfer, while thicker boards may slightly reduce efficiency.
Manufacturer guidelines: Always check the product’s datasheet to confirm it’s tested and approved for use with underfloor heating systems.

By following these specifications, you’ll ensure safe, efficient heating performance and long-lasting flooring stability throughout the seasons.

Types of Underfloor Heating Systems That Work Best

Both electric and water-based (hydronic) underfloor heating systems can work effectively with LVT and SPC flooring, as long as installation is done correctly. The right system for your home will depend on the subfloor, budget, and the size of the heated area.

Electric systems: These use heating mats or wires placed directly beneath the flooring and are ideal for smaller areas like bathrooms, kitchens, or home offices. They're easier and cheaper to install, especially in renovations.
Water-based systems: Also known as hydronic systems, these circulate warm water through pipes embedded in the subfloor. They're more suitable for larger spaces and whole-house heating but usually require more upfront installation work.

Click-lock LVT/SPC floors with built-in underlay are often used with electric UFH, while glue-down variants are commonly paired with hydronic systems. The key is to follow both the flooring and heating system manufacturer’s compatibility instructions to ensure safe performance.

Do You Need Underlay?

Whether or not you need underlay depends on the type of LVT or SPC flooring you choose and the underfloor heating system being used. Not all vinyl floors require separate underlay—especially if they already come with an integrated acoustic or thermal backing.

If an underlay is needed, make sure it's specifically designed for use with underfloor heating. Look for features such as:

Low tog rating: This ensures minimal thermal resistance, allowing heat to transfer efficiently to the surface.
Thermal conductivity: Underlays made from materials like XPS or mineral wool are typically more heat-conductive.
Moisture protection: Especially important when installing over concrete subfloors to prevent trapped condensation.

Always check the flooring manufacturer’s recommendations. Some click systems may even be invalidated if used with the wrong underlay. For more options, browse our range of underlay and insulation products suitable for vinyl flooring.

Installation Tips for Optimal Results

To ensure the success of your LVT or SPC flooring installation over underfloor heating, proper preparation and a few specific steps are essential. Skipping these may lead to flooring damage or inefficient heating performance.

Acclimate the flooring: Leave your vinyl planks in the room for at least 48 hours before installation. This allows the material to adjust to the ambient temperature and humidity.
Gradually increase temperature: After installation, do not switch the heating system on at full power. Instead, raise the temperature slowly—no more than 5°C per day—until the desired level is reached.
Use compatible adhesives: For glue-down installations, select an adhesive approved for use with underfloor heating. This ensures long-lasting bond strength despite heat exposure.
Follow subfloor guidelines: The surface must be flat, dry, and clean. Subfloor moisture levels should not exceed 75% RH (relative humidity).

Correct installation not only improves the lifespan of your flooring but also ensures that your heating system operates at its full potential. If you're unsure whether to use a floating or glued method, check out our guide on Glue-Down vs Floating Installation.

Mistakes to Avoid

Even though LVT and SPC flooring are compatible with underfloor heating, some common mistakes can lead to performance issues or long-term damage. Knowing what to avoid will help ensure a successful, trouble-free installation.

Skipping product compatibility checks: Not all LVT or SPC floors are approved for use over heated subfloors. Always confirm the product’s datasheet or consult the manufacturer.
Overheating the floor: Setting the heating system above 27°C can cause vinyl planks to expand, warp, or lose structural integrity.
Using incorrect underlay: A thick or non-compatible underlay can act as a heat barrier, reducing efficiency and trapping heat that may damage the flooring.
Ignoring acclimation: Installing cold planks directly from storage without letting them adjust to room temperature can result in gapping or buckling once the floor heats up.

Avoiding these pitfalls will ensure your LVT or SPC floor performs beautifully for years to come, while maximising energy efficiency and heating comfort.

Conclusion: LVT and SPC Flooring Work Beautifully with Underfloor Heating

With the right approach, both LVT and SPC flooring can deliver style, durability, and cosy underfoot warmth when installed over underfloor heating. Their low thermal resistance, stability, and design versatility make them a great match for homes seeking comfort and efficiency.

Just remember: follow installation guidelines, use compatible underlay and adhesives, and never exceed the maximum temperature of 27°C. When in doubt, speak with an expert before making your decision.
