Another input: on my BBQ I sometimes get very low heat after changing tanks.
Undoing the regulator, whacking it on my leg (percussive maintenance), and
then reattaching it (the valve, the leg stays attached the whole time)
usually fixes the problem. I'm guessing a bit of moisture or dirt gets into
the tank fitting when its off.
