Thermoscreed Loose Wire Screed Heating Kit – Thermostat

In Screed Heating

Thermoscreed is ideal for new build projects where height build up is not limited. Designed for use in 20 – 50mm screed layers. In Screed heating systems allow the floor layer to prepare a perfectly flat floor to lay the floor covering over. Thermoscreed is suitable for almost any flooring finish including wood, carpet and vinyl.

Thermoscreed is a versatile heating cable designed for installation in the screed layer of new builds or renovation projects. It creates an energy efficient heating system by warming the screed to create a slow release thermal mass. Suitable for use with sand and cement, anhydrite and flow screeds.

Full kit ready for installation

The Thermoscreed matting is available in a kit which includes all the items (except insulation) that you will require for installation of your underfloor heating.  Please note: The fixing tape is the standard fixing method and is included in the kits however alternate fixing methods are available.

Kit items include: Thermoscreed Cable, Fixing tape, Programmable Thermostat (5220A), Floor Temperature Sensor, Sensor Conduit, Cable Monitor(6025), Installation Guide & Warranty Form.

  • Lifetime warranty

    We are so confident in the quality of Thermoscreed Underfloor Heating that we give each system a warranty that lasts a lifetime with 3 year warranty on the thermostats.

  • Robust, hard wearing cable

    The advanced protective PVC coating on Thermoscreed cables protects the heating element during installation and provides a long product life span.

  • In Screed heating

    Suitable for installation in screeds of 20mm to 50mm, and is recommended to be fixed to insulation boards.

  • Efficient storage heating effect

    In Screed systems have a slower heat up and cool down time and are suited to rooms that are in constant use.

  • Flexible cable spacing

    The heating output per m² can be adjusted by varying the cable spacing to achieve your architects designed heating output for the room. We recommend an output of 180-220m² under screed.

Frequently Asked Questions


What is the minimum and maximum thickness for In Screed Heating?

In Screed Heating is designed to be installed in screed layers between 20-100mm.

How does the heat-up time of In Screed heating compare with Undertile heating?

In a typical Undertile build-up the floor heating will take 2-4hours to reach temperature and for In Screed heating cable under a 25mm of screed it would also take approx. 2-4hours. However, for every additional 25mm of screed you will need to allow an additional hour for the heat to penetrate.

Do I need Galvanised Fixing Profile or In Screed Mesh?

All In Screed Heating kits are supplied with a fixing tape to attach the heating cable to the substrate. The galvanised fixing profile and in screed mesh are alternate fixing methods that can be used. The galvanised fixing profile needs to be nailed into the substrate so is only suitable for use on a substrate that has not been waterproofed whereas the In Screed Mesh is a loose lay mesh that can be installed onto a waterproofed substrate.

Is Underfloor Heating safe to be installed in the shower?

Providing that the shower floor is tiled (not a shower base) like the rest of the bathroom floor, all of Thermogroup’s underfloor heating systems are suitable for installation in the shower area.

The cable has an IP (Ingress Protection) rating of IP68 and a continuous earth braid the full length of the cable. This ensures it is safe should the cable come in contact with water and gives you the assurance of safety in the unlikely event of install damage. For further protection we recommend that you do not end the heating system in the shower area.

Can Underfloor Heating be installed up the side and on top of a shower seat?

All Underfloor Heating cable must be covered by a cement-based product and cannot operate in a void. Therefore, provided that the shower seat is tiled like the rest of the bathroom and all cable is covered by a cement-based flexible tile adhesive, then it is perfectly safe to install the heating on a shower seat.

What is the best Underfloor Heating system for my application?

If you are unsure which floor heating system best suits your needs or daunted by the many options and offerings on the market, Thermogroup's online underfloor heating system selector tool can help you make the best decision. Our underfloor heating selector takes you through a simple four step process to determine the most suitable underfloor heating system for your individual application then also lists out all the products required to get the job done, so you can be assured that you will have everything required when it comes to installation. If you have any requirements outside of those specified on the tool do not hesitate to contact us to discuss your requirements.

Should Underfloor Heating be installed below or above the waterproofing?

To ensure a fully waterproof substrate it is recommended to lay the floor heating over the waterproofing. In a screed application, where the waterproofing is on top of the screed, an in screed system can be laid before the waterproofing.

What are the rough in or first fix requirements for Underfloor Heating and a Controller?

When roughing in for our Underfloor Heating and the controller, the electrician will first need to bring mains power to the Thermostat location. The electrician will then also need to run two 20mm conduits from the Thermostat position down to the floor, for the Underfloor Heating Cold Tail and for the Floor Sensor. For further information and a visual representation, please view our Conduit Requirements download.
