When planning the heating system for your home or office, one of the first questions that usually comes up is: how much energy will it consume? In Malta, where electricity bills are always a topic of conversation, this is especially important. Underfloor heating mats are becoming increasingly popular because they deliver comfort, luxury, and even efficiency. But to make a smart decision, you need a clear understanding of the energy consumption of underfloor heating mats, how it compares to traditional heating options, and what it means for your monthly expenses.
In this article, we’ll break down everything you need to know. From actual energy usage to cost examples in euros, you’ll walk away with a practical picture of whether underfloor heating mats are a good fit for your property in Malta.
Why Energy Consumption of Underfloor Heating Mats Matters| Energy Consumption of Underfloor Heating Mats
Before diving into numbers, let’s talk about why this is such a key issue.
Energy consumption doesn’t just affect your wallet. It influences:
Monthly electricity bills: In Malta, households are particularly conscious of their kWh usage, since rates can add up quickly.
Environmental footprint: Energy-efficient systems help reduce carbon emissions and align with global sustainability goals.
Comfort and efficiency: A heating system with optimized energy consumption can warm your space without unnecessary waste.
This is why understanding the energy consumption of underfloor heating mats is more than just crunching numbers—it’s about making a responsible and long-term investment.
How Much Energy Do Underfloor Heating Mats Actually Use?| Energy Consumption of Underfloor Heating Mats
The energy consumption of underfloor heating mats depends on three main factors:
Wattage per square meter
Most electric mats are rated between 150W to 200W per square meter.
For example, a 10m² room using a 150W mat will consume around 1.5 kW per hour if running at full capacity.
Insulation quality
Well-insulated floors and walls reduce heat loss, meaning the mats don’t need to run as often.
Poor insulation leads to higher consumption since the system works harder to maintain warmth.
Usage patterns
Do you run it all day, or just in the mornings and evenings?
Many homeowners in Malta use programmable thermostats to only heat when necessary, cutting consumption by up to 30%.
👉 Realistic Example for Malta:
Let’s say you install underfloor heating mats in a 15m² living room at 150W/m². That equals 2.25 kW per hour at full use. If you run the heating for 4 hours per day, consumption is:
2.25 kW x 4h = 9 kWh per day.
At an average cost of €0.14 per kWh in Malta, that’s about €1.26 per day or €37.80 per month during colder months.
Of course, with proper insulation and smart thermostats, you could lower that by 20–40%.
Comparing Energy Consumption of Underfloor Heating Mats with Other Heating Systems| Energy Consumption of Underfloor Heating Mats
How does the energy consumption of underfloor heating mats stack up against other systems commonly found in Malta?
Air Conditioners (Heat Pumps)
Modern inverter air conditioners can be very efficient, but they often create uneven heating and require frequent use to maintain comfort.
While they might use less kWh overall, the comfort level of warm floors is hard to beat.
Gas Heaters
Gas systems are less common in Malta due to installation restrictions and safety concerns.
They can sometimes be cheaper per kWh but lack the convenience and even heat distribution of electric mats.
Traditional Electric Heaters
Standard heaters can consume 2,000W or more constantly while only heating the air near them.
In contrast, underfloor heating mats provide uniform warmth with less need for prolonged operation.
So, while the energy consumption of underfloor heating mats may look similar on paper, their ability to heat evenly and efficiently often results in lower practical usage compared to traditional methods.
Benefits That Offset the Energy Consumption of Underfloor Heating Mats| Energy Consumption of Underfloor Heating Mats
At this point, you might be thinking: If they consume around the same energy as other systems, why should I consider underfloor heating mats? Great question.
Here are some advantages that help balance out consumption:
Even Heat Distribution
Instead of hotspots or cold corners, your entire floor radiates warmth, creating consistent comfort.
This allows you to set the thermostat lower while still feeling warmer.
Quick Warm-Up Times
High-quality mats can heat tiles within 30 minutes to 1 hour.
This reduces the need for all-day operation.
Smart Thermostat Integration
By using timers and sensors, you can cut energy consumption by up to 40% without sacrificing comfort.
Long-Term Investment
Underfloor heating mats have a lifespan of 20+ years, meaning the energy usage evens out compared to replacing multiple traditional heaters.
Healthier Indoor Environment
No blowing air or dust circulation as with fans or AC.
This improves air quality and overall living comfort.
In short, while the energy consumption of underfloor heating mats is an important factor, their comfort and efficiency benefits often outweigh the numbers on your energy bill.
Real-Life Scenarios: Energy Consumption in Maltese Homes| Energy Consumption of Underfloor Heating Mats

Long-Term Cost Analysis: What Does It Mean for Your Wallet in Malta?
When considering the energy consumption of underfloor heating mats, one thing to remember is that energy usage must always be weighed against long-term value. At first glance, you may think running heating mats costs the same as running an air conditioner or electric radiator. But the reality is often more favorable.
1. Initial Investment vs. Running Costs
Installation Costs: The upfront price for underfloor heating mats in Malta can range between €30 to €60 per m², depending on the brand and system.
Running Costs: As we saw in earlier scenarios, this can be as little as €19/month for small apartments and up to €189/month for large villas.
Unlike traditional heaters that require replacements every 5–10 years, mats typically last over 20 years. This means that your investment stretches over decades, making the energy costs easier to absorb.
2. Increased Property Value
Adding an underfloor heating system can increase your property’s market value. Prospective buyers often view it as a luxury feature, especially in Malta’s competitive real estate market. This helps balance out the energy consumption of underfloor heating mats by boosting resale potential.
3. Lifestyle Benefits vs. Bills
While a bill of €30–€80 a month may feel noticeable, the comfort of warm floors on Malta’s cooler winter mornings is priceless for many homeowners.
Sustainability: A Greener Side to Energy Consumption of Underfloor Heating Mats
Another important angle to consider is sustainability. Malta, like much of Europe, is moving toward renewable energy and efficient housing practices.
Here’s how underfloor heating mats align with those goals:
Efficient Heat Transfer: Radiant heating is one of the most energy-efficient ways to distribute heat, because there is very little energy loss compared to systems that heat air first.
Lower Operating Temperatures: Unlike radiators or AC units, underfloor heating works effectively at lower temperatures (25–30°C floor temperature).
Solar Integration: Many Maltese homeowners are investing in solar PV panels. Pairing solar with underfloor heating mats allows you to offset much of the electricity cost.
Reduced Carbon Footprint: Even if your mats consume electricity, efficient usage patterns and insulation can significantly reduce wasted energy compared to outdated heating systems.
In other words, while the energy consumption of underfloor heating mats is real, they are still a greener option than many traditional heaters when managed wisely.
Advanced Efficiency Strategies
For homeowners who want to maximize comfort while minimizing energy bills, here are some expert strategies:
1. Heat Only Essential Areas
Instead of heating bedrooms that are rarely used during the day, focus your mats in bathrooms, kitchens, and living spaces.
2. Smart Zoning Systems
Modern underfloor heating mats allow for zone-based control. For example, you can heat the bathroom for an hour in the morning and the living room in the evening.
3. Floor-Sensing Thermostats
Invest in a thermostat that measures floor temperature, not just air temperature. This avoids overheating and keeps your energy consumption balanced.
4. Layered Heating Approach
Many Maltese households combine underfloor heating mats with air conditioners (heat pumps). Mats handle comfort during colder hours, while AC is used sparingly if needed for larger temperature changes.
5. Night-Time Energy Savings
Program your mats to turn off overnight, when you are asleep under blankets. You can reduce usage by 20–30% without noticing a comfort loss.
Debunking Common Myths About Energy Consumption of Underfloor Heating Mats
When people first hear about radiant floor heating, misconceptions are common. Let’s clear up a few myths.
❌ Myth 1: They Are Too Expensive to Run
✅ Reality: When used with smart thermostats and insulation, the energy consumption of underfloor heating mats is similar—or even lower—than traditional heaters.
❌ Myth 2: They Waste Energy Because They Heat the Whole Floor
✅ Reality: Radiant heating is efficient because the warmth rises evenly. You can also install mats only in key rooms, not across the entire property.
❌ Myth 3: They Can Only Be Installed in New Homes
✅ Reality: Modern mats are thin and designed for retrofitting. Many Maltese apartments and townhouses are adding them without major renovation.
❌ Myth 4: They Need Constant Operation
✅ Reality: Underfloor heating warms up quickly (30–60 minutes), so they don’t need to run all day.
By breaking these myths, it’s clear that the energy consumption of underfloor heating mats is not as daunting as many initially believe.
The Maltese Perspective: Why Underfloor Heating Mats Make Sense Locally
Malta doesn’t experience harsh winters like Northern Europe. But anyone who has lived here knows that January and February can feel chilly indoors because Maltese homes often lack central heating and insulation.
This is where underfloor heating mats really shine:
Perfect for Malta’s Climate: You don’t need powerful boilers or radiators—just a gentle, consistent warmth under your tiles.
Cost-Effective for Short Winters: Since heating is only used 2–3 months a year, the energy consumption of underfloor heating mats remains manageable.
Tile-Friendly: Most Maltese homes use ceramic or porcelain tiles. These materials are excellent conductors, making the mats highly efficient.
So, while you may only use them a few months out of the year, the comfort they bring during that period makes them a smart investment.
Case Study: A Family in Sliema
To give a real-world touch, let’s imagine a family in Sliema with a 20m² living room fitted with underfloor heating mats.
Daily Use: 5 hours in the evenings
Wattage: 150W/m²
Monthly Cost: ~€65 in January and February
The family reports that they rarely need to use their air conditioner for heating anymore, which used to cost €90/month in winter. This means that despite the energy consumption of underfloor heating mats, their monthly expenses actually went down while comfort levels went up.
So, Are Underfloor Heating Mats Worth the Energy Consumption?
The bottom line: Yes, they are worth it.
While the energy consumption of underfloor heating mats is comparable to other systems, the efficiency, comfort, and longevity they offer make them a practical choice—especially in Malta, where heating needs are seasonal. With the right insulation and smart thermostat, the running costs are both predictable and reasonable.
Instead of seeing them as an expense, think of them as a long-term comfort upgrade that adds value to your home and improves your quality of life.
