How does an anode help against a thermal expansion crack in the wall?

1) there should be a thermal expansion tank in the system to stop major pressure cycles. If you don’t have one, you’ll have dangerous high pressure spikes in the system.

2) anodes stop heavy corrosion in the system by sacrificing themselves.
