Underfloor heating is becoming one of the most popular heating solutions in the UK, thanks to its comfort, efficiency, and compatibility with modern homes. However, many homeowners still have questions before deciding whether it’s the right option for their property.
This FAQ guide answers the most common questions about underfloor heating, helping you make an informed decision before installation. It also explains how Fastwarm underfloor heating systems simplify the process for both new builds and renovation projects.
What Is Underfloor Heating?
Underfloor heating is a system that heats a room by warming the floor surface, allowing heat to rise evenly throughout the space. It can be installed as either:

What’s the Difference Between Electric and Water Underfloor Heating?
Electric underfloor heating uses heating cables or mats and is ideal for:
- Bathrooms and kitchens
- Single-room installations
- Renovation projects
Water underfloor heating uses warm water circulated through pipes and is best for:
- Whole-home heating
- New builds and extensions
- Properties using boilers or heat pumps
Fastwarm supplies both systems, allowing you to choose the best option for your project.
Is Underfloor Heating Expensive to Run?
Underfloor heating is generally cheaper to run than traditional radiator systems when properly designed.
Key cost benefits include:
- Lower operating temperatures
- Even heat distribution
- Reduced energy waste
Water underfloor heating offers the lowest long-term running costs, especially when paired with a heat pump.
Can Underfloor Heating Be Used with Heat Pumps?
Yes. Underfloor heating is one of the most efficient heating solutions to use with air source and ground source heat pumps.
Because underfloor heating operates at low temperatures, it allows heat pumps to run efficiently and consistently.
Fastwarm’s water underfloor heating systems are fully compatible with heat pump installations.
Is Underfloor Heating Suitable for Existing Homes?
Yes. Underfloor heating can be installed in both new builds and existing properties.
Fastwarm offers low-profile underfloor heating systems designed to:
- Minimise floor height increases
- Reduce installation disruption
- Work efficiently in renovation projects
This makes underfloor heating accessible for a wide range of property types.
What Floor Coverings Work with Underfloor Heating?
Underfloor heating works with most floor finishes, including:
- Tiles and stone
- Engineered wood
- Laminate flooring
- Vinyl and LVT
- Carpet (with suitable tog rating)
Choosing the correct floor covering helps maximise heat transfer and efficiency.
How Long Does Underfloor Heating Take to Warm Up?
Warm-up times depend on the system type:
- Electric underfloor heating heats up quickly, often within 30–60 minutes
- Water underfloor heating takes longer but retains heat for longer periods
Using a programmable thermostat helps optimise warm-up times and efficiency.
Do I Need Special Thermostats?
Yes. Underfloor heating requires dedicated thermostats designed for low-temperature heating.
Fastwarm offers:
