Underfloor heating is an increasingly popular choice for modern homes, providing efficient, even warmth without the need for bulky radiators. But while it's a smart investment, poor planning or incorrect installation can lead to costly errors and underperformance.
If you're planning to install underfloor heating, here are five common mistakes to avoid to ensure you get the most out of your system.
1. Skipping the Insulation Layer
One of the most overlooked but critical components of any underfloor heating system is insulation. Without it, a large portion of your heat could escape downward rather than warming your room.
Avoid this mistake by:
Always laying proper insulation boards beneath your heating system.
Consulting a professional to determine the right thickness and material for your floor type.
2. Choosing the Wrong System for Your Floor Type
There are two main types of underfloor heating: electric and water-based. Not every system suits every floor construction or property type.
Electric systems (like Fastwarm’s) are ideal for:
Renovations
Smaller areas
Quick installations
Water systems are better for:
New builds
Larger areas
Long-term energy efficiency

3. Incorrect Spacing or Layout of Heating Elements
Improper layout can result in hot and cold spots across the floor. Overlapping cables or uneven pipe spacing can lead to overheating in some areas and inefficiency in others.
Tips to avoid this:
Always follow the manufacturer’s recommended spacing.
Use a layout plan before installation begins.
Consider using Fastwarm’s pre-configured heating mats for easy, uniform coverage.
4. Not Using a Smart Thermostat
Underfloor heating works best when paired with a smart thermostat that can learn your habits and optimise performance.
The mistake: Installing a basic on/off thermostat limits your control and efficiency.
The fix:
Use a programmable or smart thermostat.
Fastwarm offers a variety of smart controls that enhance both comfort and energy savings.
5. DIY Installation Without Sufficient Knowledge
While it may be tempting to install underfloor heating yourself to save money, it's not a straightforward task. Mistakes can lead to expensive repairs and potential safety issues.
Avoid DIY disasters by:
Taking a certified training course
Hiring a qualified installer if you're unsure.
Underfloor heating is a brilliant addition to any home—but only when done right. By avoiding these five common mistakes, you'll enjoy efficient, long-lasting warmth and increased property value.
