RAYCHEM T2Blue electric storage heating cable
Electric storage underfloor heating is one of the most efficient and comfortable heating solutions. A key element of such a system is the selection of appropriate heating cables, which must be durable, reliable and suitable for pouring into concrete. RAYCHEM's T2Blue-10 and T2Blue-20 cables are specifically designed for electric storage heating. Their unique design makes them an ideal choice for both concrete screeds, anhydrite screeds and foundation slabs.
Heating cables designed specifically for thermal storage heating
The RAYCHEM T2Blue-10 and T2Blue-20 heating cables are distinguished by several key features that make them ideal for electric storage heating:
- Adaptation for pouring into concrete: These cables are specially designed for installation in thick concrete screeds and screeds.
- Mechanical strength: Thanks to their very high resistance to mechanical damage (>1500 N), these cables are extremely durable and can withstand the loads typical of installation in solid foundation slabs.
- Slim design: The thickness of the cables is only 6 mm, which makes them easy to install and minimizes the thickness of the required screed layer.
These properties make RAYCHEM T2Blue cables a reliable solution that will perform well in demanding conditions.
Heating cable for concrete screed and anhydrite screed
RAYCHEM T2Blue-10 - Why it's worth it: the T2Blue-10 is a 10 W/m heating cable that is ideal for use in concrete screeds and anhydrite screeds. Thanks to the possibility of laying it at smaller intervals, this cable provides:
- Very even heat distribution over the floor surface,
- Faster heating of the floor, which increases comfort,
- Lower energy consumption, because the system reaches the target temperature in less time.
Advantages of laying the cable at smaller intervals:
- Higher heat density per m²,
- Shorter system response time,
- Stable and even temperature distribution.
Technical parameters of RAYCHEM T2Blue-10:
- Power per running meter: 10 W/m,
- Voltage: 230 V,
- Recommended spout thickness: 30 - 60 mm,
- Minimum distance between conductors: 50 mm,
- Cable length: from 10 m to 200 m.
Installation example: In a concrete screed or anhydrite screed, T2Blue-10 cables are laid every 60 - 90 mm in a layer 30 - 60 mm thick above the cable. This arrangement ensures energy efficiency and fast heating.
Heating cable for concrete foundation slab
RAYCHEM T2Blue-20 - Ideal choice for thick concrete slabs For concrete foundation slabs, which are typically 20 - 25 cm thick, it is recommended to use a cable with higher heating power to ensure rapid heating and optimal energy efficiency. The 20 W/m RAYCHEM T2Blue-20 cable is an excellent choice here.
Why is more heating power beneficial?
- Faster heating of the floor: With higher heating power, the floor reaches the target temperature faster, minimizing system run time.
- Lower power consumption: The system operates more efficiently because there is no heat loss due to long heating up and cooling down.
- Stable temperature: In thick concrete slabs, it is crucial to ensure even and efficient heating.
Technical parameters of RAYCHEM T2Blue-20:
- Power per running meter: 20 W/m,
- Voltage: 230 V,
- Minimum spout thickness: 50 mm,
- Minimum distance between conductors: 50 mm,
- Cable length: from 11 m to 115 m.
Installation example: For a foundation slab 20-25 cm thick, it is recommended to lay the wires every 125 mm to achieve a power of 160 W/m². This ensures that the system heats up faster and provides optimal performance.

Comparison of RAYCHEM T2Blue-10 and T2Blue-20 heating cables
| Feature | T2Blue-10 | T2Blue-20 |
|---|---|---|
| Specific power | 10 W/m | 20 W/m |
| Minimum thickness of the screed | 15 - 30 mm | 50 mm |
| Application | Concrete screeds, anhydrite screeds, screeds | Concrete foundation slabs |
| Suggested laying spacing | 60 - 90 mm | 125 mm |
| Advantages | Uniform heat, fast heating time | Higher heating power, fast system response |
Control and savings with smart thermostats
In both cases (T2Blue-10 and T2Blue-20) it is recommended to use RAYCHEM smart thermostats, such as:
- SENZ WIFI: Remote control via mobile app, ability to set heating schedule.
- NRG-DM: A simple-to-use thermostat with a weekly schedule.
With these devices, the system achieves maximum energy efficiency and thermal comfort.
RAYCHEM TotalCare warranty - full protection for the customer.
RAYCHEM offers the only reasonable and honest warranty on the market that not only covers the product itself, but also provides comprehensive repair of the in-floor heating system. Why is the RAYCHEM TotalCare warranty unique?
- Full repair: In the event of an emergency, RAYCHEM takes care of repairing the heating system in the floor and restoring it to its original condition.
- Protection of the customer's investment: The customer does not incur additional costs for demolition, repair and restoration of the floor - which is very costly with traditional warranties from other manufacturers.
- Unbeatable value: The TotalCare warranty provides the customer with full protection and peace of mind, which is much more favorable compared to competitors' offers, where the warranty only proposes to replace the heating cable with a new one.
Why choose RAYCHEM?
- Specialization in accumulation heating: T2Blue-10 and T2Blue-20 cables are designed for efficient heating in accumulation systems.
- Unmatched durability: Mechanical strength of more than 1,500 N and slim cable design (6 mm) ensure reliability for years.
- Comprehensive Warranty: The TotalCare program includes full repair of the in-floor heating system, providing unrivaled protection for the customer's investment.
Summary
For a variety of applications such as concrete screeds, anhydrite screeds and concrete foundation slabs, RAYCHEM's T2Blue-10 and T2Blue-20 cables are the best choice. With their durability, efficiency and TotalCare warranty support, they are the ideal solution for modern storage heating systems. When you choose RAYCHEM, you are investing in thermal comfort, energy savings and peace of mind for years to come.
