screeded systems aren’t feasible. These systems allow minimal fl oor build-up, often less than 20 mm, making them ideal for older properties where ceiling heights or door thresholds are a constraint.
Going beyond completion While operational effi ciency is a cornerstone of regulatory compliance, embodied carbon is increasingly part of the sustainability conversation. According to Government-backed studies, modern UFH systems have a signifi cantly lower embodied carbon footprint than radiator systems, up to 93% less. PE-RT (polyethylene of raised temperature resistance) pipe used in many UFH systems has a long lifespan. It can be safely recycled, making it both durable and environmentally responsible.
Partnering for performance & comfort
Precision system design is essential to ensure that UFH systems deliver the required heat output while meeting project- specifi c criteria. Working with a reputable supplier that can support CAD layouts, heat loss and heat output calculations, controls integration, and commissioning advice is crucial. This ensures that all elements, from fl ow temperatures to zoning, are designed with compliance and long-term performance in mind.
While new-build projects offer a clean slate, architects must also consider how heating systems can be retrofi tted to accommodate heat pump technology in existing homes
heat pumps, delivering effi cient, evenly distributed heat throughout the home. The low temperature radiant heating method boosts energy performance, enhances long-term occupant comfort, and assists in meeting low-carbon building standards.
Designing for retrofi t readiness While new-build projects offer a ‘clean slate,’ architects must also consider how heating systems can be retrofi tted to accommodate heat pump technology in existing homes. This is where UFH provides a major advantage. A well-designed UFH system with appropriately spaced pipe centres and increased pipe diameters (e.g. 17 mm over 12 mm) can futureproof a property for a heat pump upgrade, ensuring optimal output at lower temperatures. Low-profi le systems offer a practical solution for retrofi ts or extensions where

Radiant heat from UFH supports energy performance and enhances indoor air quality and occupant wellbeing. Unlike convected heat from traditional systems, which can stir up dust and allergens, UFH delivers even warmth across the entire fl oor surface with minimal air movement. This reduces the spread of airborne particles and can help lessen symptoms for allergy and asthma sufferers. It also provides a more consistent thermal gradient, with the warmest temperatures at fl oor level, exactly where it’s needed most.
In a fast-changing regulatory landscape, architects must specify heating systems that offer end users effi ciency and comfort in equal measure. Underfl oor heating is proven to strike that balance, particularly when paired with ASHPs. It offers a versatile, design-led solution that aligns with the UK’s roadmap to net zero and elevates the standard of living in every project.
