How do you come up with that? 24V across 24.5 Ohms is only ~1A,
therefore 25W. I still say the problem is using DC where AC is called
for, resulting in cooking the coil. Hunter valves use AC.

I'm assuming the OP hasn't done anything that foolish.


Didn't he say he was using DC?

DC would work fine so long as the voltage was reduced below specification.
