Ever wondered why more new build homes are choosing underfloor heating over traditional radiators? If so, you're not alone. This guide unpacks the key differences, benefits, challenges, and answers your most pressing questions about underfloor heating vs radiators FAQs.
Jamie Alberts, director of Peak Underfloor Heating Ltd, shares his expert perspective to help you make an informed choice for your home or project.
Opening Hook: Why Choose Underfloor Heating Over Traditional Radiators?
Understanding why people switch to underfloor heating vs radiators starts with appreciating its growing popularity and the reasons behind it. Unlike radiators, which have been the heating standard since the 1960s and 70s, underfloor heating offers an efficient, space-saving alternative that can enhance comfort and energy efficiency. Jamie Alberts explains, "Underfloor heating has evolved steadily over the years, especially because it helps save space and reduces running costs compared to radiators."
Many homeowners seek heating solutions that are discreet yet effective. Radiators can obstruct wall space and limit interior design options. Conversely, underfloor heating frees your walls and offers more consistent warmth. So if you’re looking to upgrade your home's comfort or design, this could be the perfect time to consider underfloor heating.
Overview of Underfloor Heating vs Radiators
How Underfloor Heating Works: Thermal Mass and Heat Distribution
At its core, underfloor heating takes advantage of the floor itself as a giant radiator. Pipes or electric coils beneath the floor surface warm the entire floor area, distributing heat evenly throughout the room. This concept is built on thermal mass — the ability of materials like concrete to hold and radiate heat consistently.
Jamie Alberts of Peak Underfloor Heating explains: "The ethos of underfloor heating is that the floor becomes the radiator, providing a more even and comfortable heat distribution." Unlike radiators, which concentrate heat in one area, underfloor heating creates a gentle, permeating warmth that fills the space from the ground up, making for a cozy and balanced environment.
For those interested in practical ways to maximise efficiency and reduce heating expenses, exploring cost-effective heating strategies can offer actionable tips that complement the benefits of both underfloor heating and radiators.
Radiators: Quick Heat but Higher Running Costs
Traditional radiators work by heating water to high temperatures — often between 60 to 70 degrees Celsius — that circulates through metal panels fixed on walls. This heats the air nearby quickly, making rooms feel warm fast.
However, Jamie notes: "While radiators heat up quickly, underfloor heating maintains warmth longer due to thermal mass, which can lead to lower energy bills." Radiators tend to have hotspots and cold spots and consume more energy due to the higher running temperatures required, resulting in higher operating costs compared to underfloor systems.
Benefits of Underfloor Heating Compared to Radiators
Space Efficiency and Aesthetic Advantages
One of the primary advantages of underfloor heating vs radiators is the superior space efficiency it offers in modern heating systems. Without bulky radiators on your walls, you gain more usable floor-to-ceiling space and better freedom in interior design. This can make rooms feel larger and less cluttered.
Jamie Alberts highlights this advantage: "Without radiators on the walls, you free up your space and avoid the dusty surfaces radiators attract. Plus, underfloor heating provides a clean and sleek look, perfect for modern living." The seamless integration beneath the floor means heating is invisible, giving properties a stylish and minimalistic appeal.
Lower Running Costs and Compatibility with Heat Pumps
Another attractive benefit is the lower running costs and energy efficiency achievable through an underfloor heating system. Because it operates at lower water temperatures — typically between 35 to 50 degrees Celsius — it uses less energy than radiators, which often run much hotter.
Jamie explains, "We use Swedish-manufactured flow tanks that can run at just 30 degrees, which pairs exceptionally well with heat pumps. This means utility bills can be up to a third lower, reducing your home's carbon footprint."
This makes underfloor heating an excellent match for modern low-carbon heating technologies like air source heat pumps, which are designed to operate efficiently at lower temperatures.
Challenges and Considerations When Choosing Underfloor Heating vs Radiators
Installation Complexity and Retrofit Options
Despite its benefits, underfloor heating installation is more complex than fitting an existing radiator or traditional heating system. It requires careful planning of floor build-ups, insulation, and screed to create efficient thermal mass. This process is straightforward for new builds but can present challenges for existing homes.
Jamie shares, "For retrofit installations in joisted floors or older houses, we use specialist systems like aluminum heat spreader plates or pre-routed chipboard panels. It's crucial to assess floor height constraints and insulation to determine the best approach." Retrofits often involve additional costs and careful design to avoid raising floor levels excessively.
Control Systems and Heat Regulation
Control is another key area where underfloor heating differs from radiators. While radiators are usually controlled via a central thermostat or multiple radiator valves, underfloor heating typically uses room thermostats linked to manifold control systems.
Jamie explains, "Underfloor heating works to keep a constant, flat temperature line rather than the quick on/off cycles radiators have. This can cause a learning curve for users, but it also results in more comfortable and energy-efficient heating over time."

Underfloor Heating in New Builds and Existing Homes
New Build Installations
Installing underfloor heating in new builds is typically simpler and more cost-effective compared to retrofitting existing radiator systems. The system can be integrated into the design from the earliest stages, allowing for floor insulation, screed depth, and manifold placement to be optimised.
Jamie describes the process: "We start with a site visit, assess the floor construction, then collaborate on heat loss calculations and design layout. This approach guarantees performance and efficiency from day one."
Retrofitting Underfloor Heating
For existing properties, retrofitting underfloor heating requires specialized solutions due to limited floor height and insulation constraints. Systems using aluminium heat spreader plates or reduced screed depths are common to minimise disruption and floor height changes.
Jamie advises, "We listen carefully to clients’ needs and evaluate what retrofit options suit their home best, balancing performance with practical constraints."
Common FAQs on Underfloor Heating vs Radiators
Is it better to have radiators or underfloor heating?
Each system has pros and cons. Radiators provide quick heat and lower installation costs; underfloor heating offers superior comfort, efficiency, and space-saving but at higher upfront cost. Underfloor heating is preferred for modern, energy-efficient homes, especially when paired with heat pumps.
What is the downside of underfloor heating?
Higher installation costs and slower heat-up times are key downsides. Retrofitting can be complex. It also requires careful programming and control management, which some users find tricky initially.
