When planning a renovation or upgrading your home’s heating system in Malta, one of the most common questions we get is: how long does underfloor heating sheet take to warm up? This isn’t just a matter of comfort—it affects energy use, daily routines, and even your electricity bill. In this post, we’ll break it all down with clarity, backed by real-world comparisons and actionable tips.
TL;DR: Most electric underfloor heating sheets take between 20 and 45 minutes to warm up, depending on insulation, floor covering, and room size. But there’s much more to understand…
Understanding the Basics: How Underfloor Heating Sheets Work| How Long Does Underfloor Heating Sheet Take to Warm Up
To understand how long does underfloor heating sheet take to warm up, we need to first grasp what these systems are and how they differ from traditional heating methods.
Underfloor heating sheets are thin, electrically powered mats that are laid directly beneath your floor covering—be it tile, laminate, or engineered wood. These sheets emit radiant heat, which travels upward and warms the room evenly, eliminating cold spots.
Unlike bulky radiators, heating sheets warm the entire surface area of a room. Because the heat is distributed evenly, you don’t need to run them as hot to feel comfortable. This leads to faster warm-up times in most cases.

What Affects the Heat-Up Time?| How Long Does Underfloor Heating Sheet Take to Warm Up
So, how long does underfloor heating sheet take to warm up? The truth is: it varies depending on several factors. Let’s break them down.
1. Flooring Material| How Long Does Underfloor Heating Sheet Take to Warm Up
Some flooring types conduct heat better than others:
Tiles or stone: Excellent heat conductors. Your underfloor heating sheet may take just 20 to 30 minutes to reach optimal warmth.
Laminate or vinyl: Slightly slower than tile but still efficient—expect 30 to 45 minutes.
Carpet (not recommended): Heats up very slowly and insulates the heat, delaying warm-up to over 1 hour in many cases.
Choosing a floor that’s compatible with your heating sheet is crucial. For faster results, tiles are your best friend.
2. Insulation Beneath the Floor| How Long Does Underfloor Heating Sheet Take to Warm Up
Insulation boards or foil layers beneath the heating sheets can cut warm-up times in half. Without proper insulation, a lot of the heat will get lost downward, especially on concrete or uninsulated subfloors.
In Malta’s older buildings, adding insulation is often the most cost-effective way to reduce heating costs and increase performance.
3. Room Size and Shape| How Long Does Underfloor Heating Sheet Take to Warm Up
Larger or irregularly shaped rooms might take longer to heat evenly. For instance, a compact bathroom may be fully warm in under 20 minutes, while an open-plan kitchen-living room combo might require closer to 45 minutes.
4. System Wattage| How Long Does Underfloor Heating Sheet Take to Warm Up
Higher-wattage heating sheets (typically 150–200W per square metre) heat up faster. Lower-wattage systems might be more economical to run but take longer to warm.
Kibitec’s underfloor heating sheets available in Malta use high-efficiency technology that keeps energy use low while heating rapidly.
Real-Life Warm-Up Times: What to Expect in Malta| How Long Does Underfloor Heating Sheet Take to Warm Up
Let’s look at a few common scenarios we’ve handled for homeowners in Malta to see what heating times you might expect.
Modern Apartment in Valletta
Floor type: Porcelain tiles
Room size: 15 m²
Insulation: Yes
Heat-up time: 20–25 minutes
System: 160W heating sheet
Traditional Townhouse in Rabat
Floor type: Laminate
Room size: 20 m²
Insulation: Partial
Heat-up time: 35–40 minutes
System: 150W heating sheet
New Build in St. Julian’s
Floor type: Natural stone
Room size: 30 m²
Insulation: Full thermal board
Heat-up time: 25 minutes
System: 200W high-performance sheet
This shows that with proper insulation and the right flooring material, you can enjoy warm floors in under half an hour in most Maltese homes.
How Underfloor Heating Sheets Compare to Other Systems| How Long Does Underfloor Heating Sheet Take to Warm Up
Now that we’ve explored how long does underfloor heating sheet take to warm up, let’s compare it to other heating systems available in Malta.
| Heating System | Average Warm-Up Time | Energy Efficiency | Installation Cost | Maintenance |
|---|---|---|---|---|
| Electric Underfloor Sheet | 20–45 minutes | ⭐⭐⭐⭐ | €€ | Low |
| Hydronic Underfloor | 1–3 hours | ⭐⭐⭐⭐⭐ | €€€€ | Medium |
| Wall Radiators | 30–60 minutes | ⭐⭐ | €€ | High |
| Split Unit ACs (Heating) | 5–15 minutes | ⭐⭐⭐ | €€ | Medium |
Conclusion:
While split-unit air conditioners warm the air quickly, they don’t heat the floor or surfaces, which makes the room feel colder. Hydronic systems take longer and cost more to install. Radiators can leave cold zones.
Underfloor heating sheets strike the perfect balance between comfort, heat-up time, and energy efficiency—especially in Malta’s mild to moderate winter climate.
Why Heat-Up Time Matters More Than You Think| How Long Does Underfloor Heating Sheet Take to Warm Up
When you’re asking, how long does underfloor heating sheet take to warm up, you’re really asking:
Can I turn it on just before waking up and have it warm in time? ✅
Will I be wasting energy if I leave it on too long? ❌
Is it fast enough for spot heating just a bathroom or hallway? ✅
If you live in a modern Maltese apartment with good insulation, fast heat-up time can mean lower bills and better comfort. It also allows for more flexible use—turn it on only when needed.
Advanced Tips to Maximize Warm-Up Time Efficiency| How Long Does Underfloor Heating Sheet Take to Warm Up
Now that we’ve answered how long does underfloor heating sheet take to warm up, and how it compares to other systems, let’s go a step further. There are several ways to optimize your system so you get faster warm-up, lower energy use, and better day-to-day comfort—especially during Malta’s cooler months.
1. Use Programmable Thermostats
A modern programmable thermostat is your secret weapon.
Pre-heat: Set the system to switch on 30 minutes before you wake up or get home.
Zoning: Only heat specific rooms at specific times. No need to warm the whole house 24/7.
Precision: Maintain consistent temperatures without overheating, saving on your Enemalta bill.
Some thermostats even allow you to control the heating via smartphone apps—ideal for adjusting while you’re away or traveling.
2. Upgrade Floor Insulation
Even the best electric sheets will perform poorly if the heat is being lost downward.
In Malta, where many homes are built with concrete subfloors, it’s essential to add thermal insulation boards underneath. For example:
6mm to 10mm insulation board can reduce warm-up time by 30–50%.
It helps retain warmth longer after the system switches off, so you use less power.
This small investment (about €12–€20 per m² installed) can yield excellent long-term returns.
3. Use Boost Modes
Many systems now come with a boost function, which temporarily increases power output for faster heating. This is useful for:
Post-shower bathroom heating
Guests visiting on a cold day
Quickly warming tiled kitchen floors in the morning
Use it sparingly to avoid excessive energy use—but it’s a great tool when you need quick warmth.
Common Misconceptions About Underfloor Heating Sheets in Malta| How Long Does Underfloor Heating Sheet Take to Warm Up

❌ Myth 1: “They take too long to heat up”
✅ Truth: With proper setup, most systems in Malta heat up in under 30 minutes—faster than radiators or hydronic systems.
❌ Myth 2: “You have to leave them on all the time”
✅ Truth: Thanks to programmable thermostats and fast heat-up times, you can turn them on only when needed. You don’t need 24/7 operation.
❌ Myth 3: “They only work under tiles”
✅ Truth: Heating sheets can be installed under laminate, vinyl, or even engineered wood, as long as you use compatible products.
