I go with Jerry. The pump is essentially dead weight until you get
the thermostat open (Yeah, I know, it circulates in a closed loop,
etc) and has little effect on closed cycle warmup time unless you're
in the frozen North with the heater on. Slow warmup is almost a dead
giveaway for a sticking thermostat.
