What is standard EN 442 Delta-T 50°C?
EN 442 rates radiators at 75°C flow, 65°C return and 20°C room temperature, yielding an arithmetic mean temperature difference (Delta-T) of 50°C.
Calculate required panel radiator length and heating capacity (Watt / kcal/h) for rooms based on area, ceiling height and EN 442 temperature regimes.
Engineered for mechanical, HVAC, piping, and design engineers in compliance with international standards (ISO, DIN, EN, ASME, ASHRAE). Load the interactive tool for real-time calculations and automated reports.
