3.75 hours is a bit quicker than my quickest batch - just a hair under 4 hours, including cleanup. Lately I have been mashing a little longer - 75 minutes to get some extra stirring of the mash (I don't recirc much anymore on my 5 gallon batches.) The 240V option with my Anvil Foundry makes getting to a boil from mash temps a breeze.
