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

The Warmup DCM-PRO System is an innovative electric underfloor heating uncoupling / decoupling system that delivers efficient heating while providing anti-fracture protection for tiled and stone floors via a specially designed membrane and clip-in heating cable.

Product Description The Warmup DCM-PRO system combines a twin-conductor heating cable with a pre-formed uncoupling membrane/mat featuring castellations (pegs/studs). The cable clips easily into the membrane at 2-, 3-, or 4-peg spacing to achieve standard outputs of 225 W/m², 150 W/m² (recommended), or 112.5 W/m² without additional fixings. This makes it ideal for wet areas, bathrooms, kitchens, and any tiled floor where crack prevention is essential. The membrane is available in peel-and-stick or fleece-back versions for quick installation over prepared subfloors. It works under tile/stone (primary) and can suit other finishes (vinyl, carpet, timber) with an extra 10 mm layer self-levelling compound.

Key Features

• Uncoupling membrane: Protects tiled floors from cracking due to subfloor movement.
• Variable output: 112.5 W/m² (4 pegs), 150 W/m² (3 pegs, recommended), or 225 W/m² (2 pegs) based on spacing.
• Easy clip-in installation: No staples, tape, or tools needed for cable fixing.
• Twin-conductor cable: Screened, ETFE-insulated, low electromagnetic fields.
• Thin profile: Minimal floor height build-up (~4.5–6 mm total with membrane).
• Suitable for wet areas: Waterproof membrane and cable.
• Lifetime warranty on cable; compatible with Warmup thermostats.

Technical Specifications

• Operating voltage: 230 V AC (50 Hz), single phase.
• Cable thickness: Approx. 4.5 mm (±0.2 mm).
• Output options: 112.5 / 150 / 225 W/m² (spacing-dependent).
• Cable output: Approx. 13–15 W per linear metre (varies slightly by model).
• Max operating temperature: Suitable for floor heating applications.
• Certifications: CE, UKCA, suitable for wet areas.

Note: Actual coverage depends on specific cable length/power rating. Cables are selected based on heated area and desired output; contact supplier for precise sizing.

Available Mats (Uncoupling Membranes)

• Peel-and-Stick Sheets (e.g., DCM-PS-X): Box of 10 sheets, covers approx. 6.7–7 m² (71.8 sqft), each sheet ~0.7 m × 1 m (2'3" × 3'3").
• Fleece-Back Sheets (e.g., DCM-F-X): Box of 10 sheets, covers approx. 6.7–7 m².
• Peel-and-Stick Roll (e.g., DCM-PS-14): Roll covers approx. 14 m² (150 sqft), dimensions ~14 m × 1 m (46'7" × 3'3").
• Fleece-Back Roll (e.g., DCM-F-14): Same coverage to peel-and-stick roll.

Dimensions & Weights

• Cable: Thin profile (4.5 mm thick); weight varies by length (typically light, ~0.1–0.2 kg per 10 m).
• Membrane sheets: Per sheet ~0.7 m × 1 m × ~6 mm thick; box of 10 ~7–10 kg total (approx.).
• Membrane roll: ~14 m × 1 m × ~6 mm; weight ~13 kg (approx.).

System & Application Notes

• Ideal for tiled/stone floors in bathrooms, kitchens, living areas, and wet zones; provides anti-fracture protection.
• Install cable by clipping into membrane studs; lay membrane over level subfloor (self-adhesive or bonded).
• Use with compatible Warmup and other electric brand thermostats (WiFi/smart options available) and floor temperature sensor.
• For non-tile finishes, add a decoupling or levelling layer (min. 10 mm).
• Calculate required cable length based on area and desired W/m²; professional installation recommended for electrics.
• Compatible with 230V supply; ensure proper earthing and RCD protection.
