Yeah dealer. The no heat and modem replacement probably have nothing to do with each other. You said you don't normally use heat, and just decided to use it the day after. The heater might have been broken for some time.
Then again, they might have bumped something while changing out the modem. Not sure what it takes to do the modem job - could be near a heater connection.
