Since I have bought my home, (10 years ago) I have gone thru 2 power vent water heaters (ao smith) and am about to go on my third! At about $1500 a piece installed, I figured enough is enough. All the neighbors in my cul-de-sac have also encountered the same problem as well. Some already on their 3rd. Every other day or even more often, I have to take a tothbrush to some sensor my neighbor told me about to kick start the unit, or have to dump out a picther of water that is stationed under the relief vavle - this has literally gone on for 3 years and everyday is a crapshoot if we will wake up with hot water and have to reset the unit. Sometimes it take up to 10 times for the flame to stay on, otherwise, the fan keeps running, but no water is being cooked. Why do I have a "power vent" unit to begin with, especially since it is inefficient and a pia to use? Also, can I convert to just a regular old gas water heater? The one in my previous home lasted 13 years and is still kicking. Please give me some advice on this, otherwise I am converting to electric. Oh yeah, when the unit does start to cook the water, the "power vent" sounds like a plane taking off the entire time it runs - which makes sitting out back dreadful or if we are watching an Eagles game down my finished basement, I have to blare the TV to compensate for the noise. Please share any thoughts or opinions and alos if I can jsut go back to a regular gas heater and why the heck I have to use a power vent. Thanks to all.
