what temperature should a calorifier be
Primary Heating Systems LTHW (maximum temperatures of 100Â°C) Low temperature hot water is the most common means ofheating. Flows are usually based on a temperature drop of 11Â°C(from 82â71Â°C). MTHW (100Â°Câ120Â°C) Medium temperature hot water systems are generally designed ona temperature drop of 30Â°C (from 120â90Â°C).
