What You'll Learn From This Guide to Underfloor Heating The essentials of underfloor heating and floor heating technologies Pros and cons of electric underfloor heating and wet systems Comparative running cost analysis Impact on energy bills and home value Key considerations for installation and maintenance How Peak Underfloor Heating Ltd can support your project Understanding Underfloor Heating: The Modern Heating System Alternative Floor heating has fundamentally changed how we approach home comfort. Underfloor heating is a type of heating system that distributes warmth beneath your feet, eliminating the need for bulky radiators and ensuring a consistent temperature throughout the room. Both electric underfloor heating and wet systems are designed to integrate with a variety of floor constructions, offering an ideal solution for both new-builds and renovation projects alike. Unlike old-fashioned radiators that heat a room through convection (warming the air), underfloor heating creates gentle, radiant heat that rises evenly from the entire floor surface. This method mimics the natural warmth of sunlight and helps stabilise humidity and air quality. Plus, because floor heating operates at lower water temperatures — often in tandem with energy-efficient heat pumps — it's a truly modern approach to home heating that aligns perfectly with today's sustainability goals. What is Underfloor Heating and How Does It Work? Underfloor heating systems work by installing either electric cables (in electric underfloor heating) or water-filled pipes (wet systems) beneath your floor surface. These systems are typically laid over insulation boards before the final floor covering is fitted. Once the system is turned on, heat radiates gently from the entire floor, ensuring every corner of the room enjoys the same level of comfort — no cold spots, no uneven heating. "Underfloor heating creates radiant warmth from the ground up, providing even heat distribution and unrivalled comfort." — Peak Underfloor Heating Ltd The main types of underfloor heating make use of lower operating temperatures compared to conventional central heating systems, which can translate directly into reduced energy usage. With underfloor heating, you have more flexibility in interior design, as you can remove wall-mounted radiators and optimise every square metre of your living space. Warm floors, lower drafts, and a constant ambient temperature are just some of the reasons underfloor heating is soaring in popularity across the UK. Types of Underfloor Heating Systems: Electric vs Wet Systems There are two main types of underfloor heating: electric underfloor heating (also called “dry” systems) and wet underfloor heating (hydronic systems). Each has its ideal application, benefits, and installation requirements. Choosing between electric and wet systems often comes down to property type, floor construction, and budget. For example, electric underfloor heating is often selected for smaller spaces or single rooms (like bathrooms), while wet systems are popular for larger areas and full-home installations, especially in new builds or major renovations. Electric Underfloor Heating: Application and Benefits Electric underfloor heating systems use heating mats or loose cables installed directly under the floor covering. These systems fit particularly well in retrofit projects where minimising floor height build-up is essential. The heating mat is simply rolled out and connected to the mains electricity supply, making the installation process relatively straightforward and quick compared to wet systems. One of the standout advantages of electric underfloor heating is its responsiveness — it heats up quickly, providing almost instant comfort. This system is often chosen for bathrooms, kitchens, and extensions where running new pipework might be impractical. Electric underfloor heating is compatible with most flooring types, including tiles, laminate, and engineered wood, making it flexible for a variety of room designs. Wet Underfloor Heating: The Hydronic Alternative Wet systems (also called hydronic underfloor heating) involve laying a network of pipes through which warm water circulates, connected to your existing central heating system or heat pump. Wet underfloor heating is known for its long-term efficiency and suitability for heating large spaces, such as open-plan living areas, ground floors, or full homes. Although wet systems require a higher installation cost and more invasive prep work — often needing the floor to be raised and screeded — the result is an energy-efficient heating system that operates at low temperatures. When paired with energy sources like heat pumps, wet underfloor heating delivers exceptional running cost savings and comfort in the long run. It's the preferred solution for new builds or substantial renovations where you want to maximise comfort, lower your energy bill, and future-proof your home against rising energy prices. Comparison of Electric vs Wet Underfloor Heating: Cost, Usability, Suitability Feature Electric Underfloor Heating Wet Underfloor Heating Best Application Bathrooms, kitchens, small rooms, retrofits Open-plan rooms, full-house, new builds & extensions Installation Cost £75–£130 per m² (lower for small areas) £120–£200+ per m² (higher for retrofits) Running Costs Potentially higher per kWh, costs vary by usage Lower when used with condensing boilers or heat pumps Maintenace Minimal, mainly electrical checks Virtually maintenance-free if installed well Retrofit Suitability Excellent for most floor constructions Requires more complex install, best for major renovations The Pros: Why Underfloor Heating Might Be Worth It Energy-efficient heating system reduces energy bills Improved comfort and even floor heating distribution Low profile and space-saving advantages Quiet operation and modern appeal One of the most compelling reasons homeowners choose underfloor heating is the unbeatable comfort it brings. The entire floor heats up, eliminating chilly spots and allowing you to walk barefoot throughout the coldest months. Floor heating also means there's no need for visible radiators, giving you a clutter-free look and more freedom in arranging furniture. Unlike conventional heating systems that can be noisy, underfloor installations run silently, preserving the peacefulness of your living space. "Clients particularly enjoy underfloor heating's seamless aesthetic, as it eliminates radiators and maximizes living space for residential renovations." – Peak Underfloor Heating Ltd Expert Another major advantage is energy efficiency: because underfloor systems work at lower temperatures, your boiler (or heat pump) doesn’t have to work as hard. This leads to potentially lowerenergy bills and a more sustainable heating solution, especially when paired with modern insulation and smart thermostats. For many, these benefits easily outweigh the higher upfront installation cost, delivering value and comfort for years to come. The Cons: When Underfloor Heating May Not Be Worth It Higher upfront installation cost, especially for retrofit projects Potentially expensive to run if poorly specified Slower heat-up times vs. some radiator systems Not always suitable for all sub-floor constructions Despite its appeal, underfloor heating isn’t a fit for every home or budget. Retrofitting can be disruptive: floorboards may need to be lifted, insulation added, and floor heights adjusted. This can increase the installation cost and duration, particularly in older properties or those with complex layouts. If installed without expert advice, or on a poorly insulated floor, underfloor heating systems can become expensive to run, sometimes negating the gains made in comfort and energy efficiency. Another consideration is heat-up time. Because floor heating systems work using lower temperatures, they often take longer to reach their set-point compared with high-temperature radiators. Also, while electric underfloor heating is simple to install in small spaces, it can get costly if you try to heat large areas — a trade-off that’s crucial to consider during the planning stage. All these factors underscore the importance of working with professionals, like Peak Underfloor Heating Ltd, to ensure you select and install the right system for your needs. Running Costs Compared: Underfloor Heating vs Radiators Many homeowners ask whether underfloor heating is cheaper to run than radiators. The answer depends on several variables, such as insulation quality, energy tariffs, the type of underfloor system installed, and how you use your heating system. While initial installation can be higher for underfloor heating, running costs can be substantially lower, especially when paired with efficient heat pumps and smart controls. By evenly distributing heat and requiring lower operating temperatures, underfloor heating can save you money on your energy bills over time. In contrast, traditional radiators heat the air unevenly, leading to heat loss and more frequent cycling of the boiler or heat pump. This not only creates less consistent comfort, but also increases your energy consumption. Modern wet underfloor heating systems, in particular, excel in energy efficiency, making them an attractive long-term investment for owners who plan to stay in their homes for the years ahead. Is Underfloor Heating Cheaper to Run Than Radiators? Comparing the running costs of underfloor heating and radiators involves examining factors such as energy source, room size, control systems, and floor insulation.
