As the world progresses towards more sustainable and efficient home solutions, underfloor heating has steadily risen in popularity. But before you choose to invest in this heating system, it's reasonable to ask, "What is the life expectancy of underfloor heating?" Simply put, underfloor heating systems can last up to 25 to 50 years, depending on the type and maintenance level. But there's more to this than just the duration. 

In this comprehensive guide, we'll provide an in-depth look at underfloor heating, its lifespan and what influences it, providing insights to help you make an informed decision.

What is Underfloor Heating?

Underfloor heating, also known as radiant floor heating, is a modern and high-tech heating method that ensures a comfortable and consistent temperature across your rooms. Instead of traditional radiators that heat the air, underfloor heating works by radiating heat from the floor upwards, ensuring an even distribution of heat.

This heating method is not a new concept; it was used by the Romans and Koreans in ancient times. It is gaining popularity today due to its high efficiency, comfort, and low operating costs.

How Does Underfloor Heating Work?

Underfloor heating systems work by circulating warm water through continuous loops laid under the floor or using electric floor mats, creating a large radiant surface that heats the room from the floor upwards. This allows for even heat distribution, eliminating cold spots and creating a more comfortable environment.

The system is connected to your central heating but can also work independently, giving you more control over the temperature in different rooms. A thermostat is used to regulate the heat to ensure the system operates at optimal efficiency.

What are the Types of Underfloor Heating?

There are two main types of underfloor heating systems: water-based (wet) and electric (dry).

Water-Based Underfloor Heating

A water-based system uses a network of pipes linked to your boiler that circulate warm water throughout the floor to heat the space. This type of underfloor heating is typically installed during construction or major refurbishment projects as it needs to be embedded into the floor. Its initial installation cost can be high, but it's often more cost-effective in the long run, especially for larger areas.

Electric Underfloor Heating

Electric underfloor heating systems utilise electrical wires that heat up when electricity is passed through them. This system is easier to install, making it a popular choice for retrofits and smaller areas. Though its installation cost is lower, electric underfloor heating can be more expensive, particularly if your home's insulation isn't up to par.

Your choice between a water-based or electric system will depend on your home's specifications, budget, and personal preferences. BuildPro can help you decide which system would be most suitable for your home and lifestyle.

How Long Does Underfloor Heating Last?

The longevity of an underfloor heating system depends on the type of system installed. A well-installed and maintained water-based underfloor heating system can last up to 50 yearsElectric systems, while having a shorter lifespan, can still last up to 25 years. However, these estimates can vary significantly depending on factors like the quality of installation, the level of use, maintenance, and the overall quality of the components used.

Factors Affecting the Life Expectancy of Underfloor Heating

Several factors affect the lifespan of an underfloor heating system.

Installation Quality

Quality installation by professionals like BuildPro is crucial to ensure the longevity of your underfloor heating system. Mistakes during installation can lead to system failure or frequent repairs, reducing its lifespan.

System Type

Hydronic systems tend to last longer than electric ones because they have fewer components that can fail. However, electric systems can also last a long time with proper care and maintenance.


How often you use your system can also affect its lifespan. Constant use can wear out components faster, while sporadic use can lead to issues due to system stagnation.


Regular maintenance ensures that minor issues are resolved before they become major problems. Failing to maintain your underfloor heating system can drastically reduce its lifespan.

What are the Benefits of Underfloor Heating?

Underfloor heating has numerous benefits, making it a popular choice for many homeowners.

  • Efficient Heating: The most significant benefit of underfloor heating is its efficiency. The system ensures an even distribution of heat, with no cold spots. This makes it more effective than traditional radiators, which may leave parts of the room colder than others.
  • Energy Saving: Underfloor heating operates at lower temperatures than traditional radiators, yet it provides the same comfort level. This translates into significant energy savings and reduced heating costs.
  • Space Saving: With underfloor heating, you can save valuable space in your rooms. There are no radiators, giving you more freedom to design and arrange your interior spaces.
  • Improved Air Quality: Underfloor heating reduces the circulation of dust and allergens, improving the air quality in your home.
  • Silent Operation: Underfloor heating operates silently, creating a more peaceful and quiet environment than traditional heating systems that can often be noisy.

What are the Disadvantages of Underfloor Heating?

Like any system, underfloor heating has its disadvantages. Understanding these is essential before deciding whether it's the right choice for your home.

  • Installation Costs: The initial cost of installing underfloor heating can be high, especially for hydronic systems. However, the long-term savings in energy costs can offset this.
  • Installation Complexity: Underfloor heating installation can be complex and disruptive, particularly for existing buildings. It often requires a professional installer to ensure the system is set up correctly.
  • Heating Speed: Underfloor heating takes longer to heat up than traditional radiators. However, once heated, the warmth is maintained for longer, even after the system is turned off.

How Much Does Underfloor Heating Cost?

The cost of underfloor heating varies widely depending on the type of system, the size of the space, installation complexity, and whether it's part of a new build or retrofit. On average, for a new build, you might expect to pay between €25 and €50 per square meter for a water-based system or between €50 and €100 per square meter for an electric system.

While the initial cost can be higher than traditional heating systems, the increased efficiency of underfloor heating can lead to lower energy bills, providing a return on investment over time.

How to Install Underfloor Heating?

Installing underfloor heating is a task that requires expert knowledge and precision. The installation process varies depending on whether you're installing a wet or dry system and the type of flooring in your property.

In a new build or renovation project, the underfloor heating installation happens before the final floor finish is laid. The heating pipes or cables are laid out in a predetermined pattern to ensure even heat distribution. The pipes are connected to the boiler or heat pump for a hydronic system, while the heating cables are connected to the electrical supply for an electric system.

Can You Retrofit Underfloor Heating?

Yes, you can retrofit underfloor heating in an existing building, although it might be more complex and costly than installing it in a new one. The process involves lifting the existing floor, installing the underfloor heating system, and then relaying the floor.

In some cases, especially with concrete floors, installing underfloor heating without significant structural changes might be impossible. That's why engaging a professional consultation company like BuildPro is important to assess the feasibility and provide expert advice.

What are the Best Flooring Options for Underfloor Heating?

Underfloor heating is compatible with various types of flooring, but some materials conduct heat better than others.

  • Tile and Stone Floors: These are the best options for underfloor heating. They have high thermal conductivity, which means they heat up quickly and retain heat well.
  • Wooden Floors: Timber is a good insulator suitable for underfloor heating, provided the wood is not too thick and the temperature is regulated to prevent warping.
  • Laminates and Vinyl: These materials are becoming popular due to their good heat conductivity and affordability.
  • Carpet: Carpet can be used with underfloor heating, but it must be thin enough to allow the heat to penetrate. The thicker the carpet, the longer it will take for the heat to pass through.
