Underfloor heating is a heating system that uses a network of heating pipes (water-fed hydronic systems) or electric cables installed beneath your floor. Instead of circulating warm air or relying on hot radiators, underfloor heating gently radiates warmth upwards, creating a consistent and comfortable environment. Designed for highly energy efficient performance, these systems operate at low flow temperatures, often between 35°C and 45°C, making them a perfect partner for modern heat pumps. Whether you choose wet (hydronic) or electric versions, underfloor heating provides a highly efficient, invisible, and luxurious way to heat your home. The biggest benefit is how the heat is distributed: the entire surface of your floor acts as a gentle radiator, so you experience even warmth in every corner. Not only does this improve comfort, but it also supports better energy savings—especially when teamed with low-temperature systems like air source or ground source heat pumps. By moving away from high-temperature radiators, you open the door to highly efficient, low flow temperature heating, putting you in control of costs and climate impact. How Does a Heat Pump Work with Underfloor Heating? A heat pump is a renewable energy device that extracts heat from the outside air (air source) or from the ground (ground source) and delivers it to your home at a usable temperature. Unlike gas boilers, which burn fuel to generate heat, heat pumps move existing energy from one place to another, making them highly efficient—often delivering three to four times more energy than they consume. The magic happens when this technology is matched with underfloor heating systems. Since underfloor systems use large surface areas and only require low water temperatures, they’re the ideal match for a heat pump’s low flow temperature settings. Combining a heat pump with underfloor heating means your system works optimally, using less energy to achieve a comfortable interior. The result? Lower running costs, less energy use, and a dramatic reduction in household carbon emissions. This setup leverages the strength of renewable technologies—delivering continuous, gentle heat that outperforms older traditional radiators, especially in well-insulated homes. Types of Heat Pumps: Air Source and Ground Source The two main types of heat pumps for underfloor heating are air source heat pumps (ASHP) and ground source heat pumps (GSHP). Air source heat pumps extract heat from the ambient air, even when temperatures are near freezing. These units are popular in the UK due to their easier installation, lower upfront costs, and compatibility with most properties. Ground source heat pumps, on the other hand, draw warmth from the ground using a network of buried pipes; they offer even greater efficiency, especially during colder periods, but have higher installation requirements—like garden space for the pipework. Choosing between air source heat pumps and ground source heat pumps will depend on your property, budget, and energy goals. Both are excellent matches for underfloor heating systems, supporting reliable, consistent warmth with maximum efficiency. The table below illustrates the main differences: Feature Air Source Heat Pump Ground Source Heat Pump Source of Heat Extracts heat from the air Extracts heat from the ground Installation Simpler, less disruptive Requires garden/land for pipes Efficiency (COP) ~3.0-3.5 (varies by temp) ~3.5-4.5 (more stable output) Initial Cost £7,000–£12,000 on average £14,000–£24,000 on average Best for Most UK homes, retrofits, limited outdoor space Larger properties, new builds, homes with outdoor space How Underfloor Heating with Heat Pump Maximises Energy Efficiency Energy Efficiency Advantages of Underfloor Heating Systems Underfloor heating systems are engineered for energy efficiency, and they’re at their very best when run at low flow temperatures. Because the entire floor is used as a heat emitter, the system spreads warmth evenly—eliminating cold spots and needing less energy than conventional radiators. When coupled with a heat pump, underfloor heating’s low temperature demands let the pump perform at its most efficient, with COP (Coefficient of Performance) levels often triple those of older systems. This means you get more usable heat from every kilowatt consumed. For households aiming to cut down on their carbon footprint, underfloor heating systems with a heat pump deliver substantial improvements. These highly efficient systems not only reduce energy bills but also operate almost silently and are virtually invisible, giving you more flexibility with furnishing and décor. The low running costs make them appealing for both retrofits and new builds, and government incentives can help offset installation expenses, making energy efficiency accessible and financially attractive for many UK families. How Heat Pumps and Underfloor Heat Complement Each Other The synergy between heat pumps and underfloor heating is unmatched. Traditional heating systems such as gas boilers or electric heaters rely on high flow temperatures and create uneven warmth. In contrast, underfloor heating paired with a heat pump utilises a low flow temperature, resulting in gentle, sustained heat at a fraction of the energy cost. Modern floor heating systems use less water and distribute energy with precise control, helping heat pumps reach their full potential—and allowing both systems to last longer with fewer maintenance needs. Because heat pumps work most efficiently at low temperatures, underfloor heating’s ability to produce comfort using low-temperature water makes this combination ideal. It is this integration of systems that enables households to achieve the ‘gold standard’ in both luxury and energy efficient living, outperforming most traditional heating methods. Key Differences from Traditional Heating Systems When comparing underfloor heating with heat pump to traditional radiator-based or electric heating systems, the differences are significant. Radiators operate at high temperatures, making them less compatible with renewable energy systems like heat pumps. In addition, radiators typically heat the air near them first, causing ‘cold spots’ and uneven comfort. Underfloor heating delivers warmth where you need it—at your feet—ensuring even distribution across the entire room. This combination also stands out due to its environmental credentials. By using low-temperature renewable heat, these systems drastically reduce the use of fossil fuels in a typical home, and help future-proof properties against upcoming regulations and energy price increases. The installation might seem more involved at first, especially in older homes, but the return on investment—improved comfort, lower bills, and higher property values—is significant and lasting.
