Product Description

The Warmup StickyMat System 220W/m² is a high-performance electric underfloor heating solution specifically designed for tiled floors in areas with higher heat demand, such as bathrooms, en-suites, kitchens, and wet rooms.

With a powerful 220W/m² heat output, this system delivers rapid warm-up times and strong thermal performance, making it ideal for rooms with higher heat loss or where quick comfort is required.

The heating cable is pre-spaced and fixed to a self-adhesive mesh mat, allowing the mat to be rolled out directly onto the prepared subfloor. This ensures consistent heat distribution and significantly reduces installation time compared to loose wire systems, particularly in regular-shaped rooms.

The StickyMat system is installed directly into tile adhesive or a self-levelling compound, creating a robust, long-lasting heating solution beneath ceramic, porcelain, or natural stone tiles. When installed with appropriate insulation and controls, it can be used as primary or secondary heating, depending on room insulation and heat loss calculations.

Short Comparison 

Warmup StickyMat 220W/m² vs Lower-Output Heating Mats

• 220W/m² StickyMat
  Best for bathrooms, wet rooms, and higher heat-loss areas, offering fast warm-up and strong output.

• 150W–200W/m² Heating Mats
  Better suited to living areas or well-insulated rooms where steady background heating is sufficient.

Tip: Higher wattage does not always mean better — choose the output based on room heat loss and insulation.

StickyMat vs Ecofloor vs Loose Wire – Which System Should I Choose?

• StickyMat Heating Systems
  Best for tiled bathrooms and high heat-demand areas where fast warm-up is required. The self-adhesive mesh allows quick installation in regular-shaped rooms.

• Ecofloor Heating Cable Mats
  Ideal for tiled living spaces and kitchens where steady, even heat is needed. A great balance between performance and efficiency in well-insulated, regular-shaped rooms.

• Loose Wire Heating Systems
  Best for irregular room layouts or areas with fixtures such as toilets, basins, or islands. Offers maximum flexibility where precise coverage is required.

Tip: Choose your system based on room shape and heat demand, not just wattage.
