What is the typical supply water temperature for circulated hot water radiators?

• A. 110 degrees F
• B. 215 degrees F
• C. 140 degrees F
• D. 195 degrees F

Answer: (C)

The typical supply water temperature for circulated hot water radiators is around 140 degrees Fahrenheit. This temperature is effective in providing sufficient heat output for residential heating systems while maintaining efficiency and safety. Heating systems use this temperature because it strikes a balance between providing adequate warmth and minimizing heat loss through the distribution piping. At temperatures higher than this, you risk increased heat loss and might cause discomfort or even damage to some materials in the home. Therefore, 140 degrees F is commonly recommended for optimal performance and comfort in most hydronic heating applications.
