Hello: I’d check water pressure with a gauge and also look for anything that could get in the way of thermal expansion like a check valve or heat trap. Pressure should be in the 50 to 60 psi range. Sometimes if there is a valve in the way, pressure can rise quickly when reheating and make the sounds you’re hearing. Sometimes tanks moan as well. Or, perhaps that’s ghosts 😀

Yours, Larry
