Underfloor heating can be a fantastic investment for your home, providing efficient, consistent warmth, enhancing the aesthetic appeal of your rooms by eliminating radiators, and potentially increasing your property's value. Yet, it's not a decision to make lightly. This blog post will thoroughly examine the ins and outs of underfloor heating, allowing you to make an informed decision for your home.

What is Underfloor Heating?

Underfloor heating, also known as radiant heating, is a type of central heating system installed beneath the floor surface to warm the room from the ground up. This method distributes heat evenly, offering a more comfortable, uniform warmth than conventional systems like radiators that heat the air unevenly.

How Does Underfloor Heating Work?

Underfloor heating works by pumping a controlled flow of warm water from any heat source through plastic tubing embedded in the floor. The heat generated by these elements then rises into the room, ensuring a consistent level of warmth from floor to ceiling.

The warm water systems operate at a lower temperature compared to radiators, making them more energy-efficient. The system works evenly to distribute heat, providing a comfortable living environment.

Electric underfloor heating works similarly but uses electrical cables or heating mats to generate heat. These systems are generally used for smaller areas or for retrofitting in an existing space.

Types of Underfloor Heating: Electric vs Water

There are two primary types of underfloor heating systems, electric (also known as a dry system) and water-based (wet system).

Electric Underfloor Heating

Electric underfloor heating uses a network of electrical wires installed beneath or within your flooring to heat the area. There are two types of electric underfloor heating: heating mats, which are good for large areas, and loose-fit wiring, which is ideal for smaller, irregularly shaped rooms.

Water-based Underfloor Heating

Water-based systems utilise a series of pipes connected to your boiler that pump hot water around the room beneath the floor. This type of heating can be more cost-effective to run than electric underfloor heating. However, it may require some significant work during installation, as it needs to be incorporated into the floor.

Pros and Cons of Underfloor Heating

Like any home improvement decision, there are advantages and disadvantages to consider when pondering, "Is it worth having underfloor heating?"


  • Energy Efficiency: Underfloor heating typically operates at lower temperatures than traditional radiators while still heating the room to your desired temperature. This efficiency can lead to lower energy bills.
  • Space Saving: As it's installed beneath the floor, this heating system frees up wall space, allowing more freedom in designing and furnishing rooms.
  • Enhanced Comfort: Underfloor heating offers a superior level of comfort by providing even heat distribution with no cold spots.
  • Low Maintenance: Once installed, underfloor heating requires little to no maintenance, which can save costs and hassles over the long term.


  • Installation Cost: Initial installation costs can be high, particularly for water-based systems.
  • Installation Disruption: Installing underfloor heating, especially in existing homes, can cause significant disruption.
  • Heating Speed: Underfloor heating systems can take longer to warm a room than conventional radiators.
  • Limited Compatibility: Certain types of floor coverings, such as certain carpets, may not be compatible with underfloor heating systems.

Benefits of Underfloor Heating

Apart from the pros mentioned above, underfloor heating offers many other benefits.

  • Aesthetically Pleasing: By eliminating radiators, you can streamline the aesthetics of your rooms.
  • Safety and Health: With fewer dust hotspots and lower air circulation than traditional radiators, underfloor heating can benefit those with allergies. It also reduces the risk of burns or injuries from hot radiator surfaces, which is particularly beneficial in homes with children.
  • Noise-free: Underfloor heating systems operate silently, creating a peaceful environment in your home.
  • Flexibility: The system can be installed in a single room or throughout the house, providing great flexibility.

Is Underfloor Heating Energy Efficient?

Yes, underfloor heating is generally more energy-efficient than traditional heating methods. The system operates at a lower temperature while distributing the same amount of heat. Plus, it uses a thermostat and zoning controls, which means less energy is wasted. According to the Energy Saving Trust, an underfloor heating system can be 25% more efficient than radiators when paired with a modern condensing boiler and up to 40% more efficient when running with a heat pump.

Can Underfloor Heating Replace Radiators?

Absolutely, underfloor heating can replace radiators in providing a more efficient, evenly spread level of warmth. However, it's crucial to consider the type of building, insulation, and the local climate before deciding.

Is My Home Suitable for Underfloor Heating?

Most homes are suitable for underfloor heating, whether it's a new build, a renovation project, or just an update to your existing heating system. The best time to install underfloor heating is during a build or renovation, but it's possible to retrofit an underfloor heating system, especially the electric type.

However, factors such as insulation, floor type, and available space for installation will determine the suitability of underfloor heating in your home.

Installation of Underfloor Heating: Cost and Upheaval

The cost of installing underfloor heating varies depending on the type of system (electric or water-based), the size of the property, and whether it's a new build or retrofit. While the upfront cost can be higher than traditional systems, long-term energy savings can offset this expense.

The installation process can cause upheaval, especially for water-based systems requiring floor excavation. However, the process is much smoother with new builds or during major renovations.

Maintenance of Underfloor Heating

Underfloor heating systems are generally low maintenance. However, regular inspections by a professional can ensure they continue to operate at peak efficiency. In the event of a problem, identifying and resolving issues with underfloor heating can be more challenging and potentially more costly than with traditional systems due to their concealed nature.

Underfloor Heating and Different Types of Flooring

Underfloor heating is compatible with most types of flooring, including tile, stone, laminate, and certain types of hardwood. The key factor is the thermal conductivity of the material. The higher it is, the better the material is suited for underfloor heating.

However, carpeted floors require special consideration because the thick underlay can act as an insulator and block the heat. Therefore, if you plan to install underfloor heating, you need to discuss your flooring options with an expert.

How to Choose the Right Underfloor Heating System?

Choosing the right underfloor heating system depends on your home, budget, and personal preferences. Water-based systems might be more suitable for larger, new-build properties or spaces undergoing significant refurbishment, while electric systems can be more suitable for smaller areas or retrofit projects.

Consider the room size, floor type, how often the room is used, and how well-insulated it is. Discussing these aspects with an experienced consultant from BuildPro can help you make the right decision.

Is Underfloor Heating Worth Getting for Your Home?

Determining if underfloor heating is worth it comes down to personal preference, budget, and your home's specific needs. The system can be more energy-efficient, provides unparalleled comfort, and increases property value. However, it requires an initial investment that you should consider.

While it's possible to install underfloor heating in a DIY manner, it's recommended to utilise professional services for a comprehensive, problem-free installation.
