NoobHomeOwnerFilter: Where do I start troubleshooting water temperature issues?

Mrs. pdb and I bought a house in August. The two-story house was built in 2002, and has one utility closet on the main level that has a water heater and the heating unit in it. There is no wall or barrier in this closet separating the water heater and the heating unit; both units were inspected before we bought and found to be in perfect working order.
It's been getting a bit chilly lately, so we've occasionally had the heat on. We have noticed that, when the heat is on, our water doesn't get nearly as warm as it does when the heat is not on - my wife ran a bath yesterday in the upstairs bathroom that struggled to get to tepid by the time the tub was full.
The water heater doesn't have gradations for heat setting, just a dial that says "cooler" on one end and "warmer" on the other. I would estimate, on a scale of "1-cooler" and "10-warmer", the water heater is currently set to about a 3. This setting is perfectly adequate to heat the water - except, for some reason, when the heat is running.
Are these two things related somehow, or am I missing or not thinking of something else to check? The water heater is not wrapped or otherwise insulated, which I know it probably should be - would this help? What else should I be looking into?
