    Say what? You can run that puppy right up to 212 F (boiling water) if you want to. I wouldn't chill it down much below 35, though... it might freeze.

    Temperatures below 0°C (32°F) may cause separation of some molecules to a point of loosing ability to maintain a proper water/steam pressure seal. (freezing may cause a crack)


    Water temperature above 121°C (250°F) may cause pressure above system normal operation. But the radiator will probably survive the occurrence, however. the relief valve may fail.

    After you make that expensive repair and you still have the same problem, What will you check next?

    What a shame using a cast iron element in a convector for hot water ... It covers the best part

    When the surface temperature is above the ambient temperature where it is located it will transfer heat.
