5 Convincing Reasons Why Is Underfloor Heating More Efficient Than Radiators

When it comes to choosing the best heating system for your home in Malta, efficiency is key. Energy prices are rising, sustainability is on everyone’s mind, and no one wants to overpay for uneven warmth. So, the big question many homeowners ask is: is underfloor heating more efficient than radiators?

In short: yes, it is.
But the reasons go beyond just energy bills. Underfloor heating provides consistent warmth, reduces energy waste, and integrates better with modern insulation and renewable technologies.

In this article, we’ll break down five powerful reasons why underfloor heating outperforms radiators in terms of efficiency—backed by real-world comparisons and practical advice.

1. Lower Operating Temperatures, Higher Efficiency| Is Underfloor Heating More Efficient Than Radiators

One of the clearest indicators that answers is underfloor heating more efficient than radiators lies in the temperature required to heat a room.

Radiators:

• Heat water to 65°C to 75°C

• Release warmth through convection, warming air that rises to the ceiling first

• Result: Hot above, cooler near the floor — uneven warmth and wasted energy

Underfloor Heating:

• Requires only 27°C to 29°C to achieve the same comfort level

• Radiates heat evenly from the ground up

• Result: Comfortable warmth at lower temperatures with less energy consumption

In real terms, that temperature difference can mean up to 25–30% energy savings, especially when paired with proper floor insulation.

2. Better Heat Distribution Throughout the Room| Is Underfloor Heating More Efficient Than Radiators

A common frustration with radiators is hot and cold spots. You might feel warm right next to the unit, but the rest of the room often stays cool unless the system is running continuously.

Underfloor heating, on the other hand, turns the entire floor into a giant radiator. The heat rises slowly and evenly across every square meter—no matter where your furniture is placed.

Why this matters:

• Radiators work in bursts, cycling on and off to keep temperature consistent

• Underfloor heating uses slow, continuous heat, maintaining a steady temperature more efficiently

• You won’t need to run the system as long or as often

This is one of the key reasons why underfloor heating is more efficient than radiators in both small apartments and larger villas in Malta.

3. Less Heat Loss and Better Retention| Is Underfloor Heating More Efficient Than Radiators

Another aspect to consider when asking is underfloor heating more efficient than radiators is how much of the generated heat is lost.

Radiators:

• Lose heat to surrounding air quickly, especially in poorly insulated homes

• Warm air escapes through windows and ceilings rapidly

• Metal units cool down quickly once turned off

Underfloor Heating:

• Delivers radiant heat that warms objects and people, not just air

• Heat stays closer to the floor, where it’s most needed

• Systems retain warmth even after being switched off, reducing energy usage

When properly installed with insulation boards beneath, underfloor heating systems can maintain heat with minimal input—making them far more energy-efficient in Malta’s temperate winters.

4. Ideal Match for Renewable Energy Sources| Is Underfloor Heating More Efficient Than Radiators

In the era of sustainable living, more Maltese homeowners are installing solar panels, air source heat pumps, and hybrid systems. But not all heating systems are compatible.

Radiators are typically designed for high-temperature systems, meaning they demand more energy and don’t pair well with modern low-temperature technologies.

Underfloor heating, however, thrives on low temps—making it the perfect partner for renewables.

Why underfloor heating is more efficient in modern systems:

• Pairs easily with solar thermal systems and heat pumps

• Operates efficiently at low temperatures (around 30°C)

• Reduces demand on your energy system, saving more in the long run

This synergy makes it crystal clear: underfloor heating is more efficient than radiators—and future-proof, too.

5. Smart Controls = Smarter Heating| Is Underfloor Heating More Efficient Than Radiators

Efficiency isn’t just about hardware—it’s also about control. Older radiator systems often rely on manual thermostatic valves or central thermostats that don’t reflect the actual temperature in every room.

Modern underfloor heating systems come equipped with smart thermostats, allowing you to:

• Control temperatures room by room

• Set custom schedules for each zone

• Monitor energy use in real-time

• Manage your system remotely via smartphone

This precision heating means you’ll never waste energy warming rooms you’re not using—something radiator systems simply can’t match without significant upgrades.

Real-World Comparison: How It Adds Up in Malta| Is Underfloor Heating More Efficient Than Radiators

Let’s consider a real example. A homeowner in Mellieħa installed electric underfloor heating in a 90m² apartment. Here’s how the system compared to their previous radiator setup:

✅ Result: The client now saves about €35/month, or €420/year—and expects the system to pay for itself in 6–7 years.

Installation Considerations: Efficient from the Ground Up| Is Underfloor Heating More Efficient Than Radiators

Of course, not all underfloor heating systems are equal. If you’re asking is underfloor heating more efficient than radiators, the answer depends partly on how the system is installed.

Efficiency depends on:

• Proper insulation under the heating mat or pipes

• Matching the right system (electric or hydronic) to your home

• Zoning the system for optimal control

• Choosing professional installers to avoid wiring or coverage issues

• Solar thermal systems

• Heat pumps

• Energy-efficient boilers

Because it runs at lower temperatures, underfloor heating reduces overall energy consumption and supports Malta’s growing push toward sustainable construction.

9. Space-Saving Equals Energy-Saving| Is Underfloor Heating More Efficient Than Radiators

One benefit that often gets overlooked is how underfloor heating frees up usable space in your home.

Radiators take up wall space, limit furniture placement, and can block heat distribution if obstructed. With floor heating:

• You can position furniture anywhere

• Heat flows evenly across the room

• You eliminate cold spots caused by blocked radiators

This optimized layout doesn’t just look better—it allows heat to circulate more efficiently, adding to the system’s overall performance.

10. Enhanced Comfort with Zonal Control| Is Underfloor Heating More Efficient Than Radiators

Underfloor heating systems let you divide your home into heating zones, so you can:

• Warm only the rooms you’re using

• Set different temps for bedrooms vs bathrooms

• Avoid wasting energy in guest rooms or storage spaces

For example, in a Maltese townhouse with 3 bedrooms, clients commonly report up to 35% savings just by running their system more strategically—something radiators can’t easily do.

11. Underfloor Heating in Malta: Climate Compatibility| Is Underfloor Heating More Efficient Than Radiators

Malta’s mild winter climate is actually perfect for underfloor heating. Here’s why it works better than radiators in this context:

• Winters are cool, not freezing—perfect for low-temperature systems

• Radiators often overheat small spaces, wasting energy

• Underfloor heating provides gentle, consistent warmth ideal for Maltese stone or tiled floors

Whether you live in Valletta, Sliema, or Gozo, underfloor systems provide just the right amount of heat—without the spikes and cold drafts typical of radiator setups.

12. Maintenance Requirements: Less Is More| Is Underfloor Heating More Efficient Than Radiators

When it comes to efficiency, ongoing maintenance also plays a role. Radiators require:

• Bleeding to release trapped air

• Valve adjustments

• Flushing sludge buildup

• Painting and cosmetic fixes

Underfloor heating systems, especially electric ones, have almost no maintenance requirements. No moving parts. No corrosion. No bleeding. Once installed correctly, they just work.

Over time, this low maintenance translates to fewer disruptions and lower costs—yet another reason why underfloor heating is more efficient than radiators.
