When upgrading or installing a heating system, most homeowners compare underfloor heating and traditional radiators. But beyond the obvious differences in appearance, there are some key truths many people overlook when making the decision.
Here’s what you’re not being told—plus why underfloor heating might be the smarter, more sustainable choice.
1. Radiators Waste More Space Than You Think
Radiators take up wall space, limit furniture layout, and can be awkward to clean around. Underfloor heating is invisible, allowing for clean lines and better design freedom. Whether you're remodelling a modern open-plan space or a smaller room, underfloor heating kits give you full use of your walls and floors.
2. Underfloor Heating Offers More Even Heat Distribution
Radiators heat the air around them, which rises, creating cold spots and draughts. Underfloor heating warms the entire floor evenly, radiating heat upwards and creating a consistent temperature throughout the room. This makes UFH more comfortable and efficient.
3. Energy Efficiency Favors Underfloor Heating
Thanks to the lower operating temperature required, underfloor heating systems can be more energy-efficient than traditional radiators, especially when used with a modern thermostat or smart heating controls. Fastwarm’s digital thermostats help manage your system efficiently, reducing energy waste and bills.
4. Installation Isn’t as Disruptive as You Think
One of the biggest myths is that underfloor heating is a hassle to install. With Fastwarm’s electric heating kits, you can install UFH over existing subfloors with minimal upheaval. These kits are ideal for retrofitting during renovations or refurbishments.
5. UFH Can Be Used With Most Floor Types
A common misconception is that underfloor heating only works with tile or stone. In fact, Fastwarm offers specialist kits for use with laminate, engineered wood, vinyl, and even carpet. Browse our flooring compatibility guide to see what suits your home.
6. Maintenance is Minimal
Radiators require regular bleeding and can develop leaks over time. Once installed correctly, underfloor heating systems are low-maintenance, with few moving parts and no ongoing servicing required.
7. Long-Term Savings Are Real
While installation costs for underfloor heating may be higher upfront, the long-term benefits—like lower energy usage, reduced maintenance, and increased property value—can quickly outweigh the initial spend.
The Verdict
Underfloor heating is not just a modern luxury—it’s a practical, energy-efficient, and design-friendly alternative to radiators. Whether you’re building from scratch or upgrading your current heating, Fastwarm provides a wide range of electric and water systems to suit every type of home.
