I submit that your block heater doesn't work or the valves have gotten tight.
If the block heater's working, slightly tight valves are negated since they won't get cold enough to hang open.
If it's quiet you can usually hear it sizzling if it's working. Doesn't take much traffic noise to cover it up, though. A generally useful item to have around is a Kill-A-Watt, one of the uses of which is to prove that the heater is working.
