Benefits of Underfloor Heating

Efficient heating

One of the primary advantages of underfloor heating is its efficiency. Unlike traditional heating systems, which rely on radiators or space heaters to warm a room, underfloor heating evenly distributes heat throughout the entire floor. This allows for more targeted and efficient heating, resulting in energy savings and reduced heating costs.

Even heat distribution

Underfloor heating provides consistent and uniform heat distribution throughout a space. With traditional heating systems, heat tends to rise and accumulate near the ceiling, leaving the lower area of a room colder. With underfloor heating, the heat rises from the floor, providing a more comfortable and pleasant environment.

More space

Unlike radiators or space heaters, which take up valuable wall or floor space, underfloor heating is installed beneath the floor and is completely hidden from view. This allows for more freedom in furniture placement and interior design choices, ultimately maximizing the available space in your home.

Improved energy efficiency

Underfloor heating operates at lower temperatures compared to traditional heating systems. This means that less energy is required to achieve the desired level of comfort in your home. The reduced energy consumption translates into lower utility bills and a smaller carbon footprint.

Types of Underfloor Heating Systems

Electric underfloor heating

Electric underfloor heating systems consist of heating cables or mats installed beneath the flooring. The cables or mats are connected to a thermostat, which allows for temperature control. Electric underfloor heating systems are suitable for most types of flooring and are relatively easy to install.

Water-based underfloor heating

Water-based underfloor heating systems utilize hot water circulated through a network of pipes installed under the floor. The water is heated by a boiler or heat pump and is controlled by a central thermostat. Water-based systems are more suitable for new buildings or major renovations, as they require more extensive installation.

Hydronic underfloor heating

Hydronic underfloor heating combines the benefits of electric and water-based systems. It uses a mixture of hot water and anti-freeze to heat the floor, providing efficient and even heat distribution. Hydronic systems are flexible and can be customized to suit different heating requirements.

Radiant floor heating

Radiant floor heating is a type of underfloor heating that uses a combination of electric heating elements and water-based systems. This approach allows for precise control of temperature and reduces the response time. Radiant floor heating is ideal for large areas or spaces with high heat loss.

Factors to Consider Before Installing Underfloor Heating

Flooring type

Before installing underfloor heating, it is important to consider the type of flooring in your home. Most flooring materials are compatible with underfloor heating, including tile, stone, laminate, and wood. However, certain types of vinyl and carpet may not be suitable.


Proper insulation is crucial for the performance and efficiency of underfloor heating systems. Insulation helps to reduce heat loss and maximize energy savings. It is recommended to install insulation boards or panels beneath the heating elements to prevent heat from escaping downward.

Compatibility with heating system

Underfloor heating can be easily integrated with existing heating systems, such as boilers or heat pumps. However, it is important to ensure that your heating system is compatible with underfloor heating. Consult with a professional installer to determine if any modifications or adjustments are required.

Bathroom installation considerations

If you are considering installing underfloor heating in your bathroom, there are a few additional factors to consider. It is essential to choose waterproof or water-resistant flooring materials to withstand moisture. Additionally, it is recommended to install a separate thermostat for your bathroom to control the temperature independently.

Calculate heat loss

Before installing underfloor heating, it is important to calculate the heat loss of your space. This involves assessing the size of the room, insulation levels, and other factors that can affect the heat requirements. A professional installer can help you determine the appropriate system size and capacity for optimal heating.

Removal of existing flooring

In most cases, underfloor heating requires the removal of existing flooring. This allows for proper installation of the heating elements and ensures efficient heat distribution. It is important to carefully remove the flooring to avoid any damage and prepare the subfloor for installation.

Proper subfloor preparation

Subfloor preparation is crucial for the successful installation of underfloor heating. The subfloor should be clean, level, and free from any debris or moisture. Depending on the condition of the subfloor, it may require additional preparation, such as leveling compounds or moisture barriers.

Installation of insulation

Insulation is a key component of underfloor heating systems. It helps to prevent heat loss and improve energy efficiency. Insulation boards or panels should be installed on the subfloor before laying the heating elements. This ensures that the heat is directed upward into the room, rather than being lost to the subfloor.

Underfloor Heating Installation Process

Marking the layout

Before laying the heating elements, the layout of the underfloor heating system needs to be marked. This involves measuring and marking the positions of the heating cables or pipes according to the room’s dimensions and layout. A professional installer will ensure precise and accurate placement.

Laying the heating elements

Once the layout has been marked, the heating elements can be laid on the subfloor. For electric underfloor heating, this involves positioning the heating cables or mats according to the marked layout. For water-based systems, the pipes are installed using clips or special fixing systems. Care must be taken to ensure proper spacing between the heating elements for uniform heat distribution.
