Does you gas stove work? If yes, that eliminates the regulator? Check for kinks in the hosing?
If the furnace and the hot water are separated from each other, it is unlikely that two sail switches would fail simultaneously.
Are the fans coming on or are you just hearing the igniter click on and off?
