But is it really worth the investment? Let’s explore the benefits, costs and factors to consider before deciding whether underfloor heating is right for your home.

How Does Underfloor Heating Work?

Underfloor heating systems are made up of pipes installed beneath the floor surface. This setup effectively turns the entire floor into a large heat source, evenly distributing warmth throughout the room.

Unlike traditional radiators, underfloor heating warms from the ground up, creating a more consistent and comfortable indoor temperature. It operates at a lower temperature compared to radiators, which helps improve efficiency and places less strain on your boiler.

Interestingly, underfloor heating functions more like a true ‘radiator’ than conventional radiators do. It heats the floor structure, which then radiates warmth into the space, with over 80% of the heat transfer occurring through radiation rather than convection.

Underfloor heating is particularly effective when paired with renewable energy sources, such as heat pumps, which work efficiently at lower flow temperatures. This combination can enhance energy savings while reducing the environmental impact of home heating.

The Benefits of Underfloor Heating

1. Enhanced Comfort

Underfloor heating provides a consistent warmth that spreads evenly across the entire room, avoiding cold spots. Unlike radiators, which heat the air unevenly, underfloor heating ensures a comfortable environment from floor to ceiling.

2. Improved Energy Efficiency

Underfloor heating operates at lower temperatures than radiators while still effectively heating a room. This means it can be more energy-efficient, especially when paired with a modern boiler or renewable energy source like a heat pump. The system can reduce energy bills over time, making it a cost-effective choice in the long run.

3. More Space and Aesthetics

Without radiators taking up wall space, underfloor heating allows greater flexibility in interior design. This can be particularly beneficial in smaller homes where maximising space is a priority.

4. Healthier Indoor Air Quality

Unlike traditional radiators, which circulate dust and allergens as they heat the air, underfloor heating produces less air movement. This results in improved indoor air quality, making it a great option for allergy sufferers.

5. Compatible with Various Flooring Types

Underfloor heating can be installed under tiles, wood and laminate, making it a versatile choice for different styles of homes. However, some materials, such as thick carpets, may reduce its efficiency.

Things to Consider Before Investing

• Installation Costs

The upfront cost of installing underfloor heating varies depending on the type of system and the size of the area being heated. Water-based systems are typically more expensive to install but cheaper to run, while electric systems have lower installation costs but can be more costly to operate.

• Installation Process

Installing underfloor heating when an extension is being built is the ideal time. Retrofitting underfloor heating into an existing property can be disruptive, especially with a water-based system that requires lifting floors and laying pipes. We offer floor milling – a specialist process using custom-built machinery to cut the channels required into existing concrete flooring. Our process eliminates much of the dust and debris created, and means underfloor heating is easier to install in older properties than before. 

• Running Costs

Although underfloor heating is generally more efficient, electricity costs can make electric systems more expensive to run compared to gas-powered central heating. A well-insulated home will help improve efficiency and reduce running costs.

• Heating Response Time

Underfloor heating systems take longer to heat up compared to radiators. However, once the desired temperature is reached, they maintain warmth for longer. Using a smart thermostat can help manage heating schedules for efficiency.
