Warmup DCM-PRO Electric Underfloor Heating System - Loose Lay Heating Cable and Decoupling Mat

Warmup DCM-PRO Electric Underfloor Heating System - Loose Lay Heating Cable and Decoupling Mat

The Warmup DCM-PRO is onf of the world's fastest electric underfloor heating system to install — a complete two-component solution combining a loose-lay heating cable with a patented peel-and-stick decoupling membrane mat. Designed for tile, stone, vinyl, engineered wood, and carpet, it protects finished floors from subfloor movement while delivering a consistent 150 W/m² heat output. Installation is tool-free: the cable simply clips into the membrane castellations by hand, ready for tiles or a levelling compound overlay in one session.

Cable Warranty
⚡ Installer Note: Final connection to the mains supply must be carried out by a qualified electrician in accordance with BS 7671 (IET Wiring Regulations). The system must not be energised until all floor coverings are fully cured or set.
✔ Floor Compatibility: Tiles and stone can be laid directly over the DCM-PRO membrane using flexible tile adhesive. All other floor finishes (vinyl, engineered wood, carpet) require a 10 mm layer of self-levelling compound first. Minimum installation temperature: 5 °C.
🚿 Wet Room & Shower Use: With the addition of DCM-PRO Waterproofing Tape and correct installation technique, the system achieves full waterproofing suitable for walk-in showers and wet rooms.
Key Features
🔧 Tool-Free Cable Clipping

The 4.5 mm dual-core heating cable simply clips by hand into the raised castellations of the membrane — no adhesive, no tools required. Cable markings show remaining meterage so you always know how far you've run.

🛡️ Anti-Fracture Decoupling

The polypropylene membrane absorbs the lateral movement that occurs when subfloor and floor finish expand and contract at different rates — the primary cause of cracked tiles. Tested to ANSI 118.12 and awarded a High Performance crack isolation rating.

⚡ ETFE Fluoropolymer Insulation

An advanced fluoropolymer (ETFE) inner insulation surrounds the multi-stranded, dual-core conductor, giving the cable exceptional thermal tolerance and making it tough enough to tile directly over. Outer PVC sleeve protects during installation.

🏠 Two Membrane Options

Choose Peel-and-Stick for rapid adhesion on smooth, dry subfloors (no additional adhesive required; can be installed in as little as 30 minutes) or Fleece-Backed for use with any thinset on coarser or slightly damp subfloors.

🌊 IPX7 Waterproof

The DCM-PRO cable carries a full IPX7 waterproof rating, making the system suitable for all wet areas — bathrooms, en-suites, and kitchens — straight out of the box. Wet room use requires DCM-PRO Waterproofing Tape in addition.

📐 Adjustable Coverage

The loose-lay cable format lets you route around obstacles — toilets, vanity units, islands — with complete precision. 1 m² of cable covers exactly 1 m² of membrane mat at the recommended 3-castellation (≈91.8 mm) spacing.

Frequently Asked Questions
How do I fit the DCM-PRO heating cable into the mat?
No tools needed. Simply run your thumb along the top of the 4.5 mm cable to press it into the castellations of the mat. The castellations also shield the cable from site traffic until the system is covered. Warmup provides installation videos demonstrating the technique.
What is the difference between the Peel-and-Stick and Fleece-Backed membrane?
The Peel-and-Stick membrane adheres directly to smooth, dry subfloors or Warmup insulation boards with no additional adhesive — ideal for fastest installation. The Fleece-Backed membrane uses any polymer-modified thinset and is better suited to coarser or slightly damp surfaces such as raw concrete.
Which floor coverings are compatible with DCM-PRO?
Ceramic and porcelain tiles and natural stone can be laid directly over the membrane using flexible tile adhesive. For vinyl, engineered wood, laminate, and carpet, apply a 10 mm layer of self-levelling compound over the system first, then install the chosen floor covering once cured.
Can DCM-PRO be used in a wet room or walk-in shower?
Yes. The DCM-PRO cable is rated IPX7. When the membrane is installed with DCM-PRO Waterproofing Tape at all joints and upstands following Warmup's installation guide, the complete system is fully waterproof and suitable for wet rooms and walk-in showers.
Do I need a SBR primer before fitting the mat?
An SBR-based primer (mixed 1:4) is required when fixing the Peel-and-Stick mat directly onto bare concrete or timber. Priming is not necessary when installing onto Warmup cement-coated insulation boards. The surface must be clean, flat, and free of dust before the mat is applied.
Where should the floor temperature probe be positioned?
Place the thermostat's floor probe centrally between two cable runs, at least 300 mm into the heated area. The probe must not touch or cross any heating cable. Cut or chisel a channel in the insulation or subfloor as needed to prevent the probe from lifting the floor covering.
