Underfloor heating has become one of the most popular home comfort upgrades in the UK and across Europe. Yet despite its growing popularity, there are still plenty of myths and misconceptions floating around that make some homeowners hesitant to try it.
At GBHome, we specialise in underfloor heating and insulation products, so we’ve heard all the myths — and we’re here to set the record straight. Let’s bust some of the most common ones!
🔥 Myth 1: Underfloor Heating Is Expensive to Run
Truth: Underfloor heating can save you money in the long run.
Because it distributes heat evenly across the floor, it operates efficiently at lower temperatures than traditional radiators. A typical radiator system runs at around 65–75°C, while electric underfloor heating can warm a room comfortably at around 25–30°C.
When combined with good insulation boards, the system retains heat longer, meaning your thermostat doesn’t need to work as hard. The result? Lower running costs and consistent comfort throughout your space.
Pro tip: Pair your system with a smart thermostat to optimise energy use and reduce costs even further.
🧱 Myth 2: You Need to Dig Up the Whole Floor
Truth: Modern underfloor heating systems are designed for easy installation — even in existing homes.
Electric systems use ultra-thin heating mats or loose cables that can be laid directly under tiles, laminate, or vinyl flooring with minimal height increase (often less than 10mm).
For renovation projects, there’s no need for major construction. Water-based systems are ideal for new builds or large refurbishments, while electric systems are perfect for retrofits.
So no, you don’t need to rip up your entire home to enjoy warm floors!
🧊 Myth 3: It Takes Ages to Heat Up
Truth: It depends on the type of system and insulation — but with the right setup, it’s quick!
Electric underfloor heating, for example, can warm a tiled bathroom floor in as little as 15–30 minutes. If your room has high-quality insulation boards, heat is directed upwards instead of being lost to the subfloor, making warm-up times even faster.
Hydronic (water-based) systems take longer initially but are incredibly efficient for maintaining steady warmth throughout the day.
🏠 Myth 4: It Only Works with Tiled Floors
Truth: Underfloor heating works under a wide range of floor types — not just tiles!
It’s compatible with:
- Laminate and engineered wood (with proper underlay)
- Luxury vinyl (LVT)
- Carpet (with a suitable tog rating)
- Stone and ceramic tiles
Each flooring type conducts heat differently, but modern systems and thermostats allow for precise temperature control to keep your floors safe and comfortable.
💧 Myth 5: It’s Unsafe or Can Cause Overheating
Truth: When installed correctly, underfloor heating is extremely safe.
All quality systems include built-in thermal protection that prevents overheating. Electric heating cables are double-insulated, and modern thermostats include temperature sensors for automatic regulation.
If the system is installed following manufacturer guidelines, underfloor heating is not only safe — it’s one of the most reliable heating methods available.
🌿 Myth 6: It’s Not Eco-Friendly
Truth: Underfloor heating is one of the most energy-efficient ways to heat your home.
Because it uses lower operating temperatures and creates a more even heat distribution, it reduces wasted energy. When paired with insulation boards and renewable energy sources like heat pumps or solar panels, it becomes an incredibly sustainable option for modern homes.
✅ The Bottom Line
Underfloor heating isn’t a luxury reserved for new builds — it’s a practical, efficient, and safe heating solution for almost any home. By debunking these myths, we hope to show that upgrading to underfloor heating can be simple, affordable, and energy-saving.
