Best Heating Mat Options
If you are trying to choose the best electric heating mat for a tiled floor, the real decision is usually output, room type, and build-up, not just brand name. Warmup StickyMat and Flexel EcoFloor both sit in the same buyer-friendly part of the market: thin, practical, and designed for neat tiled-floor installations.
A sensible choice for many well-insulated tiled rooms where you want steady comfort heating and efficient day-to-day control.
A higher output heating mat designed for tiled floors where stronger heat-up performance may be needed.
Choose your mat size from the heated floor area only, not the full room size. Fixed units, baths, toilets, kitchen cabinets and permanent furniture are party crashers here and should not be counted.
Warmup StickyMat vs Flexel EcoFloor
Warmup StickyMat and Flexel EcoFloor are direct competitors in the same category: mesh-mounted electric heating mats for tile and stone floors. Both are designed for regular-shaped rooms, both are available in 150W/m² and higher-output variants, and both are intended to be embedded beneath a tiled finish with a suitable thermostat and floor probe.
| Feature | Warmup StickyMat | Flexel EcoFloor |
|---|---|---|
| Main use | Regular-shaped tiled rooms | Regular-shaped tiled rooms |
| Typical outputs | 150W/m² and 200W/m² / 220W/m² depending on range | 150W/m² and 200W/m² |
| Installation style | Pressure-sensitive adhesive mesh for fast positioning | Roll-out mat fixed to the floor for quick tiled-floor installation |
| Profile | Very thin, designed to minimise floor height increase | Low build height, minimal floor height build-up |
| Safety / screening | Dual-core heating wire with SafetyNet installation guarantee | Continuous metallic earth screen and wet-area suitability |
| Best buyer fit | Buyers who want premium brand support and very fast sticky-mesh installation | Buyers who want a robust low-build heating mat for tiled-floor projects |
If you are comparing Warmup StickyMat vs Flexel EcoFloor, the biggest similarity is that both are heating mats for tiled floors. The main difference is usually brand preference, preferred installation feel, warranty expectations and which product range fits the rest of your build-up best.
150W vs 200W / 220W Heating Mats: Which One Is Best?
The best output depends on whether you want steady comfort heating, faster response or stronger heat in a colder room. Higher output is not automatically better. It simply gives you more power per square metre, which can suit some rooms but increase maximum running costs.
| Heating Mat Type | Best For | Main Benefit | Running Cost Potential | Typical Buyer |
|---|---|---|---|---|
| 150W/m² Heating Mats | Well-insulated bathrooms, kitchens and general tiled rooms | Efficient everyday comfort heating | Usually lower at full output than high-output mats | Buyers wanting a balanced option for standard rooms |
| 200W/m² or 220W/m² Heating Mats | Colder spaces, rooms needing faster warm-up, or higher heat loss | Higher output and quicker response potential | Higher at full output than 150W/m² | Buyers wanting stronger performance from a tiled-floor heating mat |
If your room is reasonably well insulated and you want dependable everyday floor warming, 150W/m² is often the sensible choice. If you want a stronger output and faster heat-up in a tougher room, 200W/m² or 220W/m² may be the better option.
How Heating Mat Running Costs Work
The running cost of heating mats depends on five main things:
- the wattage of the mat
- the size of the heated area
- your electricity tariff
- how well insulated the room and subfloor are
- how well the thermostat controls the heating
The basic running cost formula is:
System kW × hours used × electricity price per kWh = running cost
That gives the maximum theoretical running cost if the system ran at full output continuously. In real use, thermostats cycle the heating on and off once temperature is reached, so actual running costs are usually lower than the headline calculation.
What Affects Heating Mat Running Costs Most?
Higher-output mats cost more per hour at full output than 150W/m² mats covering the same area.
The bigger the heated area, the higher the total wattage and the higher the maximum cost.
Good insulation reduces heat loss and often shortens the time the system needs to work hard.
Smart scheduling and accurate floor sensing can reduce waste and improve comfort.
Heating Mat Running Cost Calculator
Use this quick calculator to estimate the maximum running cost for your heating mat system. Real-world costs are often lower because thermostats cycle the heat once the floor reaches temperature.
Planning tip: heated area is usually the usable floor area only, not the total room size. Avoid counting fixed furniture, kitchen units, sanitaryware and permanent fixtures.
Heating Mat Running Cost Examples
Below are simple examples using an electricity price of £0.26 per kWh. These are example calculations for maximum output, not guaranteed real-life daily costs.
| System Example | Total Output | 1 Hour at Full Output | 4 Hours at Full Output | 7 Hours at Full Output |
|---|---|---|---|---|
| 5m² at 150W/m² | 0.75kW | £0.20 | £0.78 | £1.37 |
| 5m² at 200W/m² | 1.00kW | £0.26 | £1.04 | £1.82 |
| 5m² at 220W/m² | 1.10kW | £0.29 | £1.14 | £2.00 |
| 8m² at 150W/m² | 1.20kW | £0.31 | £1.25 | £2.18 |
| 8m² at 200W/m² | 1.60kW | £0.42 | £1.66 | £2.91 |
These figures are based on simple example maths using £0.26/kWh and assume constant full-output operation. Real running costs are often lower because the thermostat cycles the heating once the floor reaches temperature.
Example Calculation
Example: a 5m² heating mat at 150W/m²:
5 × 150W = 750W = 0.75kW
0.75 × 7 hours × £0.26 = £1.37 per day at full output.
Example: a 5m² heating mat at 200W/m²:
5 × 200W = 1000W = 1.00kW
1.00 × 7 hours × £0.26 = £1.82 per day at full output.
These are maximum output examples. A good thermostat will not normally keep the heating fully on for every minute of the heating period once the floor has warmed up.
Can Heating Mats Be Your Main Heat Source?
That depends on the room, insulation standard, heat loss and output selected. In smaller well-insulated rooms, a heating mat may be enough as the main heat source. In larger or colder spaces, it may work better as a comfort heating layer alongside another room-heating system.
| Scenario | Can Heating Mats Work Well? | Buyer Guidance |
|---|---|---|
| Small well-insulated bathroom | Often yes | A good candidate for heating mats, especially with the right output and insulation boards. |
| Average kitchen renovation | Sometimes | Often works very well for floor comfort, but total room heat demand should still be considered. |
| Older room with greater heat loss | Not always on its own | You may need higher output, better insulation, or a separate heat source. |
| Large open-plan area | Case by case | Worth comparing heating mats with foil, in-screed or other systems depending on floor finish and build-up. |
How Thermostats Help Reduce Running Costs
A thermostat is one of the biggest factors in real-world running cost control. Heating mats work best with a thermostat and floor probe so the heating can warm the floor efficiently without overshooting.
A premium smart control option for buyers wanting advanced scheduling and app-based convenience.
A very strong all-round choice for electric floor heating where accurate control and scheduling matter.
A simpler smart thermostat option that still helps control heating times more effectively.
- They stop the floor heating unnecessarily for long periods.
- They help match heat-up time to when the room is actually used.
- They can improve comfort by using floor probes to avoid temperature swings.
- They often make the difference between “pleasantly efficient” and “why is my meter glaring at me?”
For a fuller breakdown of controls, floor probes and compatibility, see the Underfloor Heating Thermostats Guide.
Why Insulation Matters So Much
Insulation boards beneath heating mats help reduce heat loss into the subfloor and usually improve warm-up times. That matters for comfort, but it also matters for costs because wasted downward heat is just money disappearing into the floor structure instead of warming the room.
A key part of improving electric floor heating performance, especially over colder subfloors.
Useful if you are still deciding which type of insulation makes sense for your subfloor and room build-up.
Recommended Heating Mat Build-Up
For most tile and stone installations, the ideal build-up aims to keep the mat close to the final floor finish while reducing downward heat loss. That usually means insulation beneath the system and a flexible adhesive or smoothing layer above it.
| Floor Type | Typical Build-Up | Buyer Benefit |
|---|---|---|
| Tiles / Stone | Subfloor → Insulation Boards → Heating Mat → Flexible Tile Adhesive or Levelling Compound → Tile or Stone Finish | Low build-up, quicker response and better tiled-floor comfort |
- Buying for the whole room size instead of the actual heated area.
- Skipping insulation boards over a cold subfloor.
- Using the wrong thermostat setup or failing to install the floor probe correctly.
- Choosing heating mats for awkward room layouts that would suit loose wire better.
- Forgetting to plan build-up height before tiling begins.

Best Heating Mat Option By Room Type
| Room Type | Usually Best Starting Point | Why |
|---|---|---|
| Small bathroom | 150W/m² or 200W/m² depending on insulation and heat demand | Bathrooms often benefit from faster warm-up, but the right choice depends on the room and subfloor. |
| Kitchen | 150W/m² in many standard situations | A balanced option where you want dependable tiled-floor comfort in a frequently used room. |
| Colder room or tougher conditions | 200W/m² or 220W/m² | Higher output may be more suitable where stronger performance is needed. |
| Well-insulated renovation | 150W/m² | Often enough where the room build-up is already reasonably efficient. |
The best heating mat is not always the one with the highest output. In many rooms, the more sensible choice is the one that matches the insulation level, room use and desired heating response.

When Heating Mats Are a Better Choice Than Other Systems
Heating mats are usually the better choice when your final floor finish is tile or stone and the room is a reasonably regular shape. If your floor is laminate, engineered wood, vinyl or carpet, you may need a different electric underfloor heating build-up instead.
| System | Best For | Why Buyers Choose It |
|---|---|---|
| Heating Mats | Tiled rooms with regular layouts | Fast installation and neat cable spacing |
| Loose Wire | Awkward tiled rooms | More flexibility around obstacles and unusual shapes |
| Foil Heating | Laminate, engineered wood and some floating floor builds | Low-build dry installation for floating floors |
| Carbon Film | Floating laminate or engineered wood builds | Wide dry-install coverage beneath suitable floors |
| DCM / Decoupling | Tiled floors needing movement protection | Heating plus crack-isolation / decoupling benefits |

How To Choose The Right Heating Mat Size
Measure the open floor area that can actually be heated, not the full room. This usually means subtracting permanent units and fixtures before selecting your mat size. Heating mats are best when they cover the available floor area evenly without bunching cable spacing or forcing awkward turns.
| Step | What To Do | Why It Matters |
|---|---|---|
| 1 | Measure the full floor area | Gives your starting room size |
| 2 | Subtract baths, toilets, fixed units and permanent furniture | These areas are usually not heated |
| 3 | Choose the nearest suitable mat coverage | Avoids buying oversized systems that do not fit correctly |
| 4 | Check the room shape | If it is awkward, loose wire may be a better fit than a heating mat |
Frequently Asked Questions
What is the running cost of heating mats?
The running cost depends on the mat wattage, room size, tariff, insulation and thermostat control. The basic formula is system kW × hours used × electricity price per kWh, but real running costs are often lower than full-output calculations because thermostats cycle the heating.
Is Warmup StickyMat better than Flexel EcoFloor?
They are very similar products in the same category. Both are designed for tiled floors and regular-shaped rooms. The best choice usually comes down to preferred brand, installation preference, output choice and the rest of your planned build-up.
Is 150W or 200W / 220W better for heating mats?
It depends on the room. 150W/m² is often a sensible choice for standard well-insulated tiled rooms, while 200W/m² or 220W/m² may be better where faster warm-up or stronger output is needed.
Do higher-output heating mats cost more to run?
Yes, at full output a higher-wattage system costs more to run than a lower-wattage system covering the same area because it uses more power.
Do thermostats reduce heating mat running costs?
A good thermostat can help reduce wasted energy by controlling heating times more accurately and switching the system on only when needed.
Do I need insulation boards under heating mats?
In most cases, yes. Insulation boards help reduce heat loss into the subfloor and usually improve warm-up time, comfort and efficiency.
Are heating mats suitable for bathrooms?
Yes. Heating mats are one of the most popular electric underfloor heating options for tiled bathrooms and similar spaces.
Can heating mats go under laminate or engineered wood?
Not usually as the standard choice. Heating mats are mainly intended for tile and stone floors. Laminate and engineered wood are usually better matched with foil or carbon film systems.
Can I install heating mats myself?
You can often complete floor preparation and mat layout yourself, but final electrical connection and testing must be completed by a qualified electrician.
Do Warmup and Flexel heating mats both suit wet areas?
Both ranges are designed for tiled-floor applications and are commonly used in bathrooms and other wet-area style projects when installed correctly with the proper controls and floor build-up.
Are heating mats good for kitchens?
Yes, heating mats are a strong option for tiled kitchens, especially where the room shape is straightforward and you want quick, even floor warming beneath tiles or stone.
Can heating mats be the main heat source in a room?
Sometimes, yes. In small or well-insulated rooms they may be enough as the primary heat source, but in colder or larger rooms they may work better as a comfort heating layer alongside another form of heating.
How do I choose the right heating mat size?
Measure the open floor area only and subtract permanent fixtures such as baths, toilets, kitchen units and fixed furniture. The correct mat size is based on the actual heated area, not the total room size.
What floor finish is best for heating mats?
Heating mats are usually best beneath tile and stone because those finishes conduct and hold heat well, making them a natural match for this type of electric underfloor heating system.
