Understanding Schluter DITRA HEAT

Schluter DITRA HEAT Kit

Schluter Ditra Heat is an innovative electric floor heating system developed by Schluter-Systems, a leading name in cutting-edge tiling solutions. It consists of an uncoupling membrane, similar to traditional Schluter DITRA, but with the added functionality of an integrated heating cable. This combination allows for efficient heat distribution while providing the benefits of uncoupling, waterproofing, and vapour management.

We also provide the option to simplify your underfloor heating installation with our selection of high-quality electric underfloor heating kits. Electric underfloor heating kits provide a convenient and cost-effective solution for heating your home. These kits are suitable for both new construction and retrofit projects, and can be installed under a variety of flooring types including tile, stone, laminate, and more.

These kits include all the necessary electrical components for a complete underfloor heating system, including electric underfloor heating mats, underfloor heating thermostats, and wiring. They are designed to be easy to install and come with detailed instructions.

What's The Difference Between Schlüter-DITRA-HEAT and Schlüter-DITRA-HEAT-DUO?


Schlüter-DITRA-HEAT-DUO features a 2mm anchoring fleece on the underside, which reduces impact sound and enables a faster heat-up response. It ensures that the bulk of the heat (approximately 80%) is channelled directly toward the tiled floor in the heat-up phase, which makes the tangible heat effect much quicker. It’s ideal for situations where heat is needed quickly and for a short amount of time.

What is Schlüter-DITRA-HEAT used for?

It’s a surface heating system, most commonly used under tiled floors. It’s all about comfort and cosy, warm feet! One of the benefits is that you can choose exactly where the heating cables are laid so you’re not heating unnecessary parts of the floor that you’ll never walk on. Schlüter-DITRA-HEAT can also be used for heating tiled walls too, which can be handy underneath robe hooks or towel rails where towels will be drying.

The Versatility of Schluter Ditra Heat

The purpose of Schluter Ditra Heat extends far beyond just providing warmth to your floors. Here's how it serves various functions:

  • Radiant Heating

    At its core, Schluter DITRA HEAT is designed to deliver radiant floor heating, which is widely regarded as one of the most comfortable and energy-efficient heating methods available. By radiating heat evenly from the floor surface upwards, DITRA HEAT creates a cosy and consistent warmth throughout the room, eliminating cold spots and maximising comfort.

  • Uncoupling and Waterproofing

    Similar to traditional Schluter Ditra, Ditra Heat serves as an uncoupling membrane, absorbing substrate movement to prevent cracks in the tiled surface above. Additionally, it acts as a waterproofing membrane, providing an extra layer of protection against moisture infiltration. This dual functionality ensures not only a comfortable indoor environment but also long-term durability and resilience.

  • Energy Efficiency

    Schluter Ditra Heat is renowned for its energy efficiency. By heating the floor directly, it minimizes heat loss and reduces energy consumption compared to traditional heating systems that rely on heating the air. This not only translates to cost savings but also contributes to a greener, more sustainable home environment.

  • Quick and Easy Installation

    Despite its advanced features, Schluter Ditra Heat is remarkably easy to install. The integrated heating cable snaps securely into the uncoupling membrane, eliminating the need for additional adhesives or fasteners. This simplifies the installation process, reducing labour costs and ensuring a faster turnaround time for your flooring project.

How Thick Is Schlüter-DITRA-HEAT?


What Is The Minimum Subfloor For Schlüter-DITRA-HEAT?

The subfloor needs to be rigid, level, load-bearing, dust-free, and dry. Schlüter can provide guidance and advice on using DITRA-HEAT on various types of subfloors. They also have a peel & stick matting version which is particularly suitable for installing over green chipboard.

Note that no more than 10mm of tile adhesive should be used on top of Schlüter-DITRA-HEAT.

Can Schlüter-DITRA-HEAT Be Installed Under Carpet?

No. Due to the insulating properties of the carpet, the heat would not reach the surface.

Can I Install Schlüter-DITRA-HEAT In Shower?

Yes, assuming the shower area is tiled. Of course, the area must be fully waterproofed and the placement of the thermostat needs to be in line with UK regulations for 230 Volt supply ie. outside of zone 0, 1, and 2. In practice, this usually means the thermostat is not installed in the bathroom or wet room.

Can Schlüter-DITRA-HEAT Be Installed Under Laminate Flooring?

Yes. We recommend a thin layer of self-leveller on top of Schlüter-DITRA-HEAT before installing your laminate flooring.


How To Program Schlüter-DITRA-HEAT Thermostat?

Schluter Thermostat

The thermostats do not need programming in order to function. You can simply set your desired temperature and the Schluter thermostat will turn the Schlüter-DITRA-HEAT system on and off as required, in order to maintain your desired temperature.

Of course, the thermostats do have many programming options, including a timed schedule so that Schlüter-DITRA-HEAT only comes on when you need it. Holiday mode allows you to set the heating of your home to a minimum while you are away on holiday, saving energy and money. The thermostat will ensure that your floor is kept above freezing point and that your floor is warm upon your return.
