Designed for quick installation on timber or concrete subfloors, it supports all major floor finishes without raising floor height significantly. Its low-profile, energy-efficient design is perfect for modern refurbishments, backed by Warmup’s reliable customer support. ## Description The Warmup Electric Underfloor Heating Sticky Mat Kit is the ideal solution for installations within regularly shaped areas, where the 0.5m wide mats can be quickly rolled out across the floor in parallel runs. Whether you are planning to use vinyl, carpet, timber, tiles, or any other underfloor heating-compatible floor finish, the StickyMat System provides exceptional performance and convenience.If you require a flat and level floor surface to lay over, the StickyMat System can be embedded within a self-levelling compound. This ensures a seamless and even finish, especially when using carpet or other delicate floor coverings. Alternatively, the Foil Heater System offers a completely dry construction and eliminates the need for a leveling compound, unless it is to be used underneath a tiled floor finish. For irregularly shaped areas or spaces with multiple permanent fixtures, such as bathrooms, the Warmup Loose Wire System is the more suitable solution. Compatible With All Floor Coverings The StickyMat system is compatible with all types of floor coverings suitable for underfloor heating, including laminate flooring, vinyl, carpet, tiles, and more. Its versatility and the fact that it does not significantly raise the floor height make it an excellent choice for refurbishment projects. However, it is always important to double-check with your flooring supplier to ensure compatibility with the StickyMat System. How does StickyMat work? The 150W/m2 variant is ideal for use as a primary heat source in well-insulated areas, as the insulation boards retain heat in the room for longer and prevent downward heat loss. It can be installed on both timber and concrete subfloors.The 200W/m2 variant is best suited for rooms or areas with high heat loss, such as conservatories. It is recommended to carry out a heat-loss calculation to assess the heating requirements of the room, especially if using the underfloor heating system as a p Review: Good heat mat - Delivered quickly. Seems like a quality mat and only about 3mm overall height which kept the height difference between old floor and new floor to a minimum. Warms the bathroom tiles nicely. Can’t really speak about reliability at this early stage but given the apparent build quality and the fact that Warmup have a support desk that can help if you have issues or even calamities like the tiler cutting through a cable, I am expecting a long life out of this mat Review: Great product - would recommend - Great product - would recommend Easy to use and good value ## Features - Excellent ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B014KS233E | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 82,888 in DIY & Tools ( See Top 100 in DIY & Tools ) 21 in Floor Heating | | Customer Reviews | 4.4 4.4 out of 5 stars (19) | | Date First Available | 28 Aug. 2015 | | Included Components | Main product | | Item Weight | 1.68 kg | | Item model number | PFM3.5 | | Manufacturer | Warmup | | Part Number | Spm3.5 | | Product Dimensions | 1 x 1 x 1 cm; 1.68 kg | | Size | 3.5m² | | Wattage | 525.00 | ## Images ![Warmup Stickymat SPM3.5 150W/m2 Warmup self-adhesive underfloor heating mat area 3.5sqm - Image 1](https://m.media-amazon.com/images/I/71SYjS29M6L.jpg) ![Warmup Stickymat SPM3.5 150W/m2 Warmup self-adhesive underfloor heating mat area 3.5sqm - Image 2](https://m.media-amazon.com/images/I/41XarJXcmXL.jpg) ![Warmup Stickymat SPM3.5 150W/m2 Warmup self-adhesive underfloor heating mat area 3.5sqm - Image 3](https://m.media-amazon.com/images/I/51tv7iXddBL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good heat mat *by F***R on 26 November 2019* Delivered quickly. Seems like a quality mat and only about 3mm overall height which kept the height difference between old floor and new floor to a minimum. Warms the bathroom tiles nicely.

Careful if you put it underfloor - have one in my studio that has a gap between the mat and the floorboard. The one directly under slate tiles in the bathroom felt very luxurious but only lasted a week before small movements in the tile severed the element and now it is entombed under the cold floor...! My bad workmanship maybe, but watch out for that. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/346667525-warmup-stickymat-spm3-5-150w-m2-warmup-self-adhesive-underfloor](https://www.desertcart.tn/products/346667525-warmup-stickymat-spm3-5-150w-m2-warmup-self-adhesive-underfloor) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-28*
