HEATING, VENTILATION & SERVICES INTERIORS


reducing the risk of cold surfaces where moisture can settle. By minimising damp conditions, UFH helps improve IAQ and reduces the likelihood of mould growth, creating a healthier, more comfortable living space.


When working alongside a specialist UFH partner to support design and installation, self-builders can feel confi dent that integrating UF into the project will enhance comfort and effi ciency while also supporting long term health and well-being.


OPTIMAL PERFORMANCE & CONSISTENT WARMTH Stable and constant spatial air temperature is essential for creating a comfortable and energyeffi cient environment. When selecting a heating system, it’s vital to understand its performance at the heat source and across the room. This knowledge ensures comfort, effi ciency, and practical room layout. Research from Energy House 2.0


revealed that UFH has the smallest temperature variation, showing only a 0.8°C difference during tests at -5°C and 0.7°C at +5°C when operated in a SAP heating pattern. This performance is signifi cantly better than that of other heating technologies, which demonstrated variations of up to 4°C,


and traditional radiators, which had a minimum spatial difference of 2.2°C. The results also demonstrated even less spatial difference was seen when the system was run in a constant ‘on’ scenario. The research proves that, when combined with air source heat pumps, the constant heating pattern achieved by hydronic UF maximises effi ciency and comfort, ensuring optimal performance and consistent warmth throughout the living space. However, when evaluating heating technologies, it’s essential to consider more than just air temperature in isolation. Factors such as heat loss during off periods, the time required to reach the desired temperature, and the balance between running costs and occupant comfort all play a crucial role. A system that is cheaper to run but slow to heat offers little benefi t if comfort levels are only reached late in the day. A detailed review of the report reveals that UFH delivers the most consistent and comfortable warmth. When holistically accounting for cost and performance, any price difference between UFH and the most costeffi cient alternative is minimal and arguably negligible. Self-builders can also feel assured by the results from the Final Summative


Assessment of the Energy House 2.0, which concluded that underfl oor heating systems’ running costs are lower than traditional radiator-only systems. This is due to their effi cient design, which maximises heat output while minimising energy input.


A COOL COMBINATION With summers becoming hotter, homes are at increasing risk of overheating. Part O of the Building Regulations, which took effect in England in June , defi nes requirements for mitigating overheating in new residential buildings. An emerging solution is the UFH system combined with a heat pump and run in reverse to offer a passive or near-passive means of heat removal. The system requires no additional or special components besides a control system designed for cooling and heating. Radiant cooling provides a fresh perspective on indoor climate control and aims to work entirely in harmony with nature rather than against it. Instead of forcing cold air out, radiant cooling works by using cold surfaces to remove the heat radiated from objects within a room.
