Q1: Is underfloor heating more expensive than radiators?
It may seem that underfloor heating is a more expensive option when compared to a radiator system. However, although underfloor heating has a higher upfront cost, it offers long-term energy savings and increased comfort, making it a smarter investment for new builds or major renovations.
Q2: Can underfloor heating work with any flooring type?
Most flooring types are compatible, including tile, stone, laminate, and engineered wood. Carpet can work too, but it needs to be low-tog for efficient heat transfer.
Q3: Is underfloor heating energy-efficient?
Absolutely. It operates at lower water temperatures and works well with renewable energy sources like air and ground source heat pumps, reducing energy bills and carbon footprint.
Q4: Do radiators heat a room faster than underfloor heating?
Yes, radiators heat up quicker, but underfloor heating provides consistent, even warmth and retains heat longer, making it more efficient overall.
Q5: Can I retrofit underfloor heating in an existing home?
Yes, there are low-profile systems designed for retrofits such as the Epic Insulation Profix range of panels. Other products such as routed chipboards replace existing floorboards and can also give a low-profile solution on intermediate or separating floors. High compressive strength routed EPS or XPS with overlay boards such as Epic Insulation HiDECK give a firm solid floor feel which also allow you to install a multitude of different floor finishes.
Q6: How long does underfloor heating last?
A well-installed underfloor heating system can last 50 years or more, compared to radiators which typically need replacing every 10–15 years for maximum efficiency.
Q7: Does underfloor heating increase property value?
Yes, underfloor heating is considered a premium feature and can make your home more attractive to buyers, especially in modern and energy-efficient homes.
Q8: Is underfloor heating safe for children and pets?
Yes, it’s very safe. There are no exposed hot surfaces or sharp edges, making it ideal for families and pet owners.
Q9: Can underfloor heating replace radiators completely?
Yes, in most cases. Underfloor heating can be your primary heating system, but in very large or poorly insulated homes, you might need supplementary heating.
Q10: How long does it take for underfloor heating to warm up?
It depends on the system and floor type, but typically 30 minutes to 2 hours. However, once warm, it retains heat for longer than radiators.
