If you’ve ever thought about adding a touch of luxury to your home with underfloor heating, you’ve probably wondered about more than just warmth and energy efficiency. Many homeowners in Malta ask one crucial question before investing: What are the noise levels of underfloor heating under tiles?
The short answer? In most cases, it’s whisper-quiet—far quieter than traditional heating systems like radiators or ducted heaters. But to truly understand what to expect, you need to look at how these systems work, what can cause noise, and how to ensure your installation remains peaceful for decades.
In this guide, we’ll break down everything you need to know about the noise levels of underfloor heating under tiles, so you can make an informed choice for your property—whether it’s a cozy flat in Valletta or a newly built villa in Gozo.
1. Why Noise Matters in Underfloor Heating| Noise Levels of Underfloor Heating Under Tiles
For many homeowners, heating is about comfort. And comfort doesn’t just mean temperature—it’s also about creating a relaxing, peaceful environment. Imagine curling up on your sofa in winter, warm from head to toe, only to be distracted by clicks, hums, or rattles from your heating system.
When it comes to noise levels of underfloor heating under tiles, most modern systems are designed to operate almost silently. Unlike radiators, which may click as they expand or whoosh as hot water flows through, underfloor heating distributes warmth evenly, without noticeable mechanical sounds.
Still, “silent” doesn’t always mean completely absent of noise. There are scenarios—often linked to installation quality or specific materials—where you might hear slight sounds. That’s why understanding the causes and solutions is so important.
2. How Underfloor Heating Works (and Why It’s Usually Quiet)| Noise Levels of Underfloor Heating Under Tiles
Before talking about noise, it’s worth understanding the basics of how underfloor heating works under tiles.
There are two main types:
Electric underfloor heating – Uses heating cables or mats installed directly beneath the tile surface.
Hydronic (water-based) underfloor heating – Uses warm water flowing through pipes embedded in a screed layer below your tiles.
In both systems, heat rises evenly through the tiled floor, creating a uniform warmth without the need for fans or visible units. Because there are fewer moving parts compared to other heating methods, the noise levels of underfloor heating under tiles are typically minimal.
Electric systems are almost silent in operation, while hydronic systems may produce a faint sound if there’s air in the pipes or if the pump is located nearby. But these noises are avoidable with proper installation and maintenance.
3. Common Causes of Noise in Underfloor Heating Systems| Noise Levels of Underfloor Heating Under Tiles
Even though underfloor heating is generally quiet, some factors can contribute to unwanted sounds:
a. Expansion and Contraction of Materials
Tiles, grout, and screed naturally expand and contract with temperature changes. This can sometimes create faint ticking or cracking noises, especially in older installations or where expansion joints weren’t properly placed.
b. Air in Hydronic Systems
In water-based systems, trapped air bubbles can lead to gurgling or knocking sounds. This usually happens if the system wasn’t fully bled during installation or after maintenance.
c. Pump or Boiler Noise
If you have a hydronic system, the pump or boiler might produce a low hum. While this noise doesn’t come from under the tiles themselves, it can still be noticeable in quieter homes.
d. Poor Installation
Incorrect spacing of pipes or cables, insufficient insulation, or improper screed thickness can all lead to minor vibrations or sounds transferring through the floor.
The good news? When installed correctly, especially by experienced professionals, the noise levels of underfloor heating under tiles are barely noticeable.
4. Comparing Noise Levels: Underfloor Heating vs. Other Systems| Noise Levels of Underfloor Heating Under Tiles
To put things into perspective, let’s compare:
| Heating Method | Typical Noise Level | Main Sources of Noise |
|---|---|---|
| Electric underfloor heating | < 20 dB (almost silent) | Minimal electrical hum (rare) |
| Hydronic underfloor heating | 20–30 dB (low) | Pump, water movement |
| Radiators | 30–50 dB | Expansion clicks, water flow |
| Ducted heating | 40–60 dB | Fan motors, air movement |
As you can see, the noise levels of underfloor heating under tiles are significantly lower than most alternatives. In fact, the sound level is comparable to a whisper or the rustling of leaves.
5. Installation Quality: The Key to a Quiet Floor| Noise Levels of Underfloor Heating Under Tiles
Here in Malta, many underfloor heating projects are part of new builds or major renovations. This is the perfect time to ensure your system is installed to the highest standard—because once the tiles are down, fixing mistakes becomes much harder (and more expensive).
Best practices for keeping noise levels low include:
Proper insulation – Reduces vibration and ensures heat efficiency.
Correct expansion joints – Prevents clicking or popping sounds.
Professional pipe or cable layout – Avoids unnecessary stress points that could create sound over time.
Quality screed application – Ensures even coverage and stability.
By working with a skilled installer, you’ll enjoy near-silent noise levels of underfloor heating under tiles for decades to come.
6. How Tile Choice Can Influence Noise Levels| Noise Levels of Underfloor Heating Under Tiles
While underfloor heating works with most tile materials, some choices can slightly affect noise perception:
Porcelain tiles – Dense and excellent for heat retention; generally low noise.
Ceramic tiles – Slightly lighter than porcelain; still very quiet.
Natural stone tiles – Can be thicker and heavier, which may muffle sound even further.
What matters most is ensuring tiles are correctly laid with flexible adhesive and grout, which can absorb minor expansion movements and help keep noise minimal.
7. Noise Levels in Maltese Homes: Special Considerations| Noise Levels of Underfloor Heating Under Tiles
Maltese homes often have specific architectural features—stone walls, open-plan layouts, and high ceilings. These can influence how sound travels. Even a faint noise from an underfloor heating system can seem louder in an empty, echo-prone room.
To counteract this, many homeowners use soft furnishings like rugs, curtains, and upholstered furniture. While these aren’t directly related to the noise levels of underfloor heating under tiles, they can make your overall space feel cozier and quieter.
8. Costs and Maintenance for a Quiet Experience| Noise Levels of Underfloor Heating Under Tiles
In Malta, the cost of installing underfloor heating under tiles typically ranges from €50 to €90 per square meter for electric systems, and €70 to €120 per square meter for hydronic systems. While this may be a bigger upfront investment compared to radiators, the payoff in comfort—and quiet—can be worth it.
Maintenance is minimal, but for hydronic systems, it’s wise to have them checked every 2–3 years to ensure there’s no trapped air or pump wear. Electric systems, once installed, rarely need servicing.
9. How to Ensure Long-Term Quiet Operation
If you want your system to remain whisper-quiet for years:
Choose an experienced installer familiar with Malta’s climate and building materials.
Opt for quality components with good warranties.
Schedule periodic checks (especially for hydronic systems).
Address any noise early before it becomes a bigger issue.
10. Final Word: Peace, Warmth, and Comfort
When installed correctly, the noise levels of underfloor heating under tiles are so low that most homeowners completely forget their system is even running—until they feel that pleasant warmth underfoot.

11. Real-Life Experiences: Noise Levels of Underfloor Heating Under Tiles in Malta
Sometimes the best way to understand what to expect is to hear from people who have already made the investment.
Take Maria, for example, a homeowner in Sliema who renovated her apartment last year. She installed electric underfloor heating under porcelain tiles in her living and dining areas. Her verdict?
“Once it’s on, I honestly forget it’s there—until I step on the warm tiles. There’s no noise at all. It’s so much better than the radiator we had before, which used to click constantly.”
Similarly, Paul, a homeowner in Gozo, opted for a hydronic system in his large open-plan kitchen. Initially, he heard faint gurgling in the first week, but after a quick visit from the installer to bleed the system, the noise levels of underfloor heating under tiles became practically non-existent.
12. Troubleshooting Minor Noises
While most systems are quiet from day one, here’s a quick guide if you do notice something unusual:
Clicking sounds – Often caused by tile expansion; check for proper expansion joints.
Gurgling in hydronic systems – Usually air trapped in the pipes; bleeding the system resolves this.
Humming from the pump – May be normal but can be reduced with vibration-dampening mounts.
Buzzing in electric systems – Rare, but could indicate a loose connection; call a qualified technician.
Addressing these issues early ensures your system stays silent and efficient.
13. Noise Levels and Property Value
One often-overlooked benefit of low-noise heating is its impact on property value. In Malta’s competitive real estate market, features that enhance comfort—without adding mechanical noise—are attractive to buyers.
A home listing that includes “underfloor heating under tiles” automatically stands out. Pair that with the fact that the noise levels of underfloor heating under tiles are almost imperceptible, and you have a selling point that appeals to anyone seeking modern, peaceful living.
14. The Science Behind Silence
The reason underfloor heating operates so quietly comes down to physics. By spreading heat evenly across a wide area, there’s no need for forced air or rapid water flow, both of which create noise in traditional systems.
Electric cables generate radiant heat without moving parts. Hydronic pipes move water slowly at low pressure, reducing turbulence. This low-speed operation is why noise levels of underfloor heating under tiles are typically around 20–30 dB—about as quiet as a library.
15. Seasonal Performance: Does Noise Change in Winter or Summer?
In Malta, winters are mild but damp, while summers are warm and dry. Underfloor heating is mostly used from late November through early March.
During these colder months, materials in your flooring may expand more than they do in summer, which could cause occasional ticking sounds. However, with correct installation, these seasonal variations shouldn’t significantly affect the noise levels of underfloor heating under tiles.
In summer, when the system is off, there is no operational noise at all.
16. The Role of Insulation in Noise Reduction
Insulation plays a dual role in underfloor heating: it boosts energy efficiency and helps keep things quiet. A properly insulated floor base prevents heat from escaping downward and absorbs any micro-vibrations that might occur.
Common insulation materials used in Malta include:
Extruded polystyrene (XPS) – Excellent thermal resistance and noise damping.
Polyethylene foam boards – Lightweight and good at absorbing impact sound.
Cork insulation – Eco-friendly and naturally sound-absorbing.
Investing in quality insulation is one of the simplest ways to ensure low noise levels of underfloor heating under tiles for the life of your system.
17. Hotel and Commercial Applications
While we’ve focused on homes, the quiet operation of underfloor heating is also a big selling point for hotels, spas, and office spaces. In environments where guests or clients expect peace, any constant background noise can be distracting.
Hotels in Valletta and Mdina have begun installing electric underfloor heating under bathroom tiles, where silence is particularly valued. Spa facilities benefit from hydronic systems in relaxation rooms, where the only sound should be soothing background music—not a clanging radiator.
18. Eco-Friendly Heating and Acoustic Comfort
Underfloor heating isn’t just quiet—it’s also more eco-friendly than many alternatives when paired with efficient energy sources.
Electric systems can be run on solar-generated power, while hydronic systems can be connected to heat pumps. These low-carbon solutions align perfectly with the fact that noise levels of underfloor heating under tiles are already low, creating comfort without compromising sustainability.
19. Myths About Noise in Underfloor Heating
Let’s clear up some common misconceptions:
Myth: All hydronic systems make gurgling sounds.
Truth: Properly bled systems are silent in operation.Myth: Electric systems can “buzz” like some electrical appliances.
Truth: Modern systems are shielded to prevent any such noise.Myth: Tile creaks mean the heating is faulty.
Truth: Minor sounds may simply be natural material movement and are not always cause for concern.
By knowing the facts, you can better judge whether the noise levels of underfloor heating under tiles in your home are normal or require attention.
20. Long-Term Maintenance Tips for Noise-Free Operation
To keep things quiet:
Schedule periodic inspections – Once every couple of years is enough.
Bleed hydronic systems – Prevents air buildup.
Protect your pump – Use anti-vibration pads.
Keep an ear out – If you hear a change, investigate early.
These simple steps can help ensure the noise levels of underfloor heating under tiles stay as low on year ten as they were on day one.
21. The Emotional Side of Silence
There’s something deeply satisfying about a warm, silent floor. It’s not just about the lack of noise—it’s about what that quiet represents: a home that works effortlessly in the background, creating comfort without demanding attention.
In our fast-paced world, silence is a luxury. And when that silence is paired with the gentle heat of underfloor heating, you get a living environment that truly supports relaxation and well-being.
