Introduction to the System
The Warmup DCM-PRO represents a sophisticated choice for electric underfloor heating system, combining anti-fracture protection with easy setup. Ideal for tiled floors, it adapts to various home needs through flexible wattage.
What is the Warmup DCM-PRO System?
The DCM-PRO is an uncoupling electric underfloor heating system that integrates a heating cable with a protective membrane. Tested to ANSI 118.12:5.4 standards, it safeguards tiled floors from cracks caused by subfloor movement. The membrane comes in fleece-backed (for adhesive application) or peel-and-stick variants, the latter reducing installation time by 40%. It's optimised for tiles but compatible with LVT, wood, and other finishes when paired with a 10mm levelling compound.
Key specifications include a 4.5mm cable thickness, IPX7 rating, and operating voltage of 220-240V. The system's low profile (5.8-6.1mm membrane thickness) minimises floor height build-up, making it suitable for UK renovations where space is at a premium.

Decoupling Properties and Ease of Installation
The decoupling membrane is central to DCM-PRO's appeal, absorbing lateral subfloor movements from thermal expansion or settling. It contracts and expands to distribute stresses evenly, preventing cracks in tiles—a common issue in UK homes with timber or concrete subfloors. The mat is a self-healing decoupling heating system, enhancing longevity.
Installation is user-friendly: the cable snaps into castellations without tools, allowing custom layouts. Peel-and-stick adheres directly, while fleece-backed uses thinset. Efficiency is about 40% faster than mats. Warmup recommends perimeter strips for edges and multimeter tests for safety.
Flexibility of Wattage and Recommended Outputs
DCM-PRO's cable allows adjustable spacing for varied outputs: closer for higher wattage, wider for lower. This flexibility suits diverse applications without multiple products.
Recommended wattages include:
- 225W/m²: For small bathrooms or rooms needing rapid heating (15-20 minutes), ideal for quick warmth in compact spaces.
- 150W/m²: Standard for larger areas like kitchens, balancing efficiency and comfort.
- 112.5W/m²: For well-insulated homes or solar integrations, minimising energy use (30-45 minutes heat-up).
Low-wattage options (41.3-82.5W/m²) support zero-carbon setups with solar batteries. Running costs in 2026 are estimated at £0.23-£0.31 per hour per m² for electric heating system under the price cap.
| Wattage (W/m²) | Use Case | Heat-Up Time | Efficiency | Room Size Example |
|---|---|---|---|---|
| 225 | Quick-heat small rooms | 15-20 min | Moderate | <5m² |
| 150 | Standard larger areas | 20-30 min | High | 5-15m² |
| 112.5 | Insulated/solar homes | 30-45 min | Very High | >15m² |
Enhancing Efficiency with Ultralight Insulation
Pairing DCM-PRO with Warmup's ultralight insulation boards (extruded polystyrene, 6-50mm thick) boosts performance. These waterproof, load-bearing boards (30 tonnes/m²) reduce heat-up times by 90% and direct heat upwards, cutting losses by 50%. R-values range from 0.11 (6mm) to 1.33 (50mm), ideal for concrete floors.
This creates efficient heat spread, ensuring uniform warmth without hotspots.

The 7iE Thermostat: Premium Smart Control
The 7iE Smart Matter WiFi Thermostat elevates DCM-PRO with Matter compatibility, integrating with Apple Home, Google Home, and Alexa for voice control and routines. Unveiled in 2025, it's hailed as the first Matter-enabled underfloor thermostat. Features include a full-colour touchscreen, customisable backgrounds (e.g., personal photos), and luxurious finishes in black or porcelain.
SmartGeo learns habits for 25% energy savings, with multi-zone control via the MyHeating app. Priced around £195, it's compatible with DCM-PRO for seamless operation.
Trends and Considerations
2026 trends favour smarter, greener heating system, with water-based alternatives for whole homes but electric like DCM-PRO excelling in zones. Considerations include initial costs (£66.80/m² ex. VAT) and professional installation for regs compliance.
In conclusion, DCM-PRO offers premium, flexible heating backed by lifetime warranty, ideal for luxurious UK homes. Buy now in our online shop.
