If water is only drawn from the cold faucet, then no, the water heater is not involved. However, if water is drawn from the hot faucet- even for a few seconds- hot water IS withdrawn from the heater, and fresh cold water drawn in to be heated- even if the hot water did not make it all the way through the pipe to the faucet- and the water heater will work to heat that fresh cold water.
