No Hot Water when Central Air is On


Apparently not.

I've never lit (or relit) the pilot light in the hot water heater (I didn't even know it has a pilot light!), only the furnace.

Are you sure the plumbing is done correctly? Maybe you are drawing hot water only from a furnace (or boiler) tankless coil and the stand alone water heater in the crawl space is not sending any water anywhere. THen when the furnace quits, no hot water.

I looked up the "furnace" model number, and it's actually a boiler. So if you have a domestic hot water coil in the boiler providing your hot water, that would explain why you get no hot water when the boiler pilot is out.
