Just got the service done on my furnace and oil fired water heater. After the service was done the tech pointed out a corroded inlet nipple on the water heater. He said the inlet nipple is "one piece" with the tank, so the whole water heater (minus the burner) needs to be replaced.

Anyone know anything about this water heater? Just trying to figure out if it is necessary to replace the whole thing or if they were just trying to sell me a bridge.

The heater is an E30GL, 30 gallon oil fired. its about 10 years old....not sure if its really past its life or not.

Thanks in advance.
