Since you have a flue I assume it is either gas/propane or oil fired. Most water heaters have cover near the base to service the burner or the igniter. First shut off the fuel source. If you remove the cover you should be able to look inside with the aid of a flashlight. Most burners are round and you may find that the cap has fallen into the center and may ...

(Electric resistance units are really about the same since they started using a reasonable amount of insulation on them.) Waiting for the one you have to fail may mean water damage and replacing it in a hurry, ...

Since the gases are hot, they will rise up a chimney flue with ease, but this also means you lose all that energy and warm air up your flue. Older heaters tend to be in older homes where there are enough drafts and air leakage to not worry too much about ventilation. ...

Most newer water heaters don't last as long as they used to. Try to find out what kind of warranty your water heater has. If it has less than a 10 year warranty, then it is only a matter of time before it fails. The majority of new heaters will be much more efficient than what you have. Keep an eye on the energy ratings. There are some that perform better ...
