Underfloor heating is a popular heating solution that offers a range of benefits, including improved heat distribution, energy efficiency, and aesthetic appeal. As experts in underfloor heating installation, we are here to provide you with all the information you need to make an informed decision about incorporating this system into your home.

What is Underfloor Heating?

Underfloor heating is a heating system that radiates heat from the floor, creating a warm and comfortable environment. It is installed beneath the flooring materials, either as a series of electric heating elements or as a network of water pipes. The heat generated from underfloor heating rises steadily, which helps to maintain a consistent temperature throughout the room.

How Underfloor Heating Works

Underfloor heating works by using either electric elements or water pipes to generate heat. Electric underfloor heating systems consist of a series of heating mats or cables, which are installed directly under the floor. These heating elements are connected to a thermostat and power supply, allowing you to control the temperature according to your requirements.

Water-based underfloor heating systems operate by circulating warm water through a network of pipes installed beneath the floor. A central boiler or heat pump heats the water, which is then circulated through the pipes to provide heat. This type of underfloor heating system offers more flexibility in terms of heat output and can be integrated with existing heating systems.

Benefits of Underfloor Heating

Heat Distribution

One of the key advantages of underfloor heating is its ability to distribute heat evenly throughout the room. Unlike traditional radiators, which only heat the immediate area around them, underfloor heating spreads warmth from the ground up. This results in a more comfortable and consistent temperature, eliminating cold spots and drafts.

Energy Efficiency

Underfloor heating is highly energy-efficient compared to traditional heating systems. This is because it operates at lower temperatures while still providing the same level of comfort. The even heat distribution also means that rooms warm up faster and retain heat for longer periods, reducing the need for constant heating.

There is nothing quite like stepping onto a warm floor on a chilly day. Underfloor heating provides a luxurious and comfortable heating solution, ensuring that your feet stay warm even on the coldest of days. It also eliminates the need for bulky radiators, giving you more freedom when it comes to designing your living space.


With underfloor heating, you no longer have to worry about unsightly radiators or ducts taking up valuable wall space. The concealed nature of underfloor heating allows for a clean and clutter-free look, giving you the freedom to decorate your home as you please. This is particularly beneficial for modern and minimalist interiors.

Types of Underfloor Heating Systems

Electric Underfloor Heating

Electric underfloor heating systems are easy to install and suitable for both new constructions and retrofitting projects. They consist of heating mats or cables that are evenly spaced and secured to the subfloor. The installation process involves laying the heating elements, connecting them to a thermostat, and then covering them with your choice of flooring material.

Electric underfloor heating is relatively inexpensive to install but can be more expensive to run in the long term, especially in larger spaces. However, advancements in technology and controls have made these systems more energy-efficient, allowing for better control of heating costs.

Water-based Underfloor Heating

Water-based underfloor heating systems are typically installed during the construction phase of a building, as they require a network of pipes to be embedded in the floor. These systems are connected to a central boiler or heat pump, which heats and circulates water through the pipes to provide warmth.

Water-based underfloor heating offers greater control over temperature and can be integrated with existing heating systems. It is also more energy-efficient in the long run, making it a popular choice for larger properties. However, installation costs and the need for professional expertise can be higher compared to electric systems.

Choosing the Right Underfloor Heating System

When considering underfloor heating, it’s important to assess your specific requirements and circumstances. Factors such as the size of the space, insulation, and existing heating system should be taken into account.

Considerations for Electric Underfloor Heating

Electric underfloor heating systems are generally easier and quicker to install, making them ideal for smaller spaces or retrofitting projects. However, they may not be as cost-effective for larger areas or rooms with high heat loss. It is important to calculate the wattage required and ensure that your electrical system can accommodate the additional load.

Considerations for Water-based Underfloor Heating

Water-based underfloor heating requires careful planning and installation, which may be more suitable for new construction or major renovations. It is essential to consider the capacity of your existing heating system, as well as the space requirements for pipes and heating controls.
