The difference between Under Tile Heating and In Screed Heating


Welcome to our blog, where we delve into the realm of underfloor heating systems. We will shed light on two popular options: Under Tile Heating and In Screed Heating. Both systems provide luxurious warmth, making cold floors a thing of the past. However, understanding their differences will help you make an informed decision when choosing the best solution for your space. Let’s dive in!


Under Tile Heating

Under Tile Heating is a radiant heating system designed to provide consistent warmth by installing heating elements directly beneath the floor tiles. It involves laying a heating mat or cable mesh across the subfloor before placing the tiles on top. The system is suitable for various floor coverings, including ceramic, porcelain, stone, and even laminate flooring.

Key Features:

  • Fast response time: Under Tile Heating warms up quickly, making it ideal for rooms that require rapid heating, such as bathrooms.
  • Even heat distribution: The system ensures uniform warmth across the entire floor surface, leaving no cold spots.
  • Energy efficiency: With its low operating temperature, Under Tile Heating minimizes energy consumption, leading to potential cost savings in the long run.


In Screed Heating

In Screed Heating, on the other hand, involves embedding the heating cables within a layer of screed or concrete mix on top of the subfloor. This method creates a thermal mass, which retains and slowly releases heat, maintaining a comfortable temperature over an extended period.

Key Features:

  • Energy storage capabilities: In Screed Heating‘s ability to store heat allows it to continue emitting warmth even after the heating system is turned off, providing an energy-efficient solution.
  • Versatility: While it is well-suited for tile and stone floors, In Screed Heating can also be used with other floor types.
  • Ideal for new constructions: This system is commonly installed during the construction phase of a building, making it an excellent choice for new homes or major renovations.


Comparing Under Tile Heating and In Screed Heating

Installation Process

Under Tile Heating: Relatively easy to install and is suitable for both new constructions and retrofitting existing floors. It does not add much height to the floor, making it ideal for rooms with low ceilings.

In Screed Heating: Installation involves pouring a layer of screed over the heating cables. This method increases the floor height, which may not be suitable for some existing spaces with height limitations.

Heating Speed

Under Tile Heating: Heats up quickly, making it ideal for spaces that need immediate warmth, such as bathrooms or kitchens.

In Screed Heating: Takes longer to heat up due to the thermal mass effect, it is still a great solution for Wet Areas. You simply need to use the programmable thermostat to switch it on a little earlier. 

Energy Efficiency

Under Tile Heating: Efficient in terms of energy usage, as it directly heats the floor surface.

In Screed Heating: Highly energy-efficient due to its ability to store and release heat gradually.


In conclusion, both Under Tile Heating and In Screed Heating offer wonderful solutions to keep your floors warm and comfortable throughout the year. Under Tile Heating excels in rapid response and ease of installation, while In Screed Heating impresses with its energy efficiency and long-lasting warmth.

We hope this comprehensive comparison has empowered you with the knowledge to make an informed decision. Consider your specific needs, space requirements, and long-term goals when choosing between these two great underfloor heating systems.
