My FIRST question would be-----------WHY?
Why even go that route? More stuff to fail. More complex and expensive to repair and/or service, etc......
Unless there is a specific reason you are going to that type of a unit, I like keeping things simple.
Also, I guess your area is prone to power outages?
You seem a bit concerned in case you lose electric service. Knowing this in advance would deter me from buying this type of HWH.
I personally have not serviced (nor own) a power vented HWH (only a boiler or furnace) but can tell you that unless you really need a power vented unit, try to stay away from them.
The problems I have encountered with power vents outweigh any benefits that I can see. Like I said, I like keeping things SIMPLE.
If you like working under the hood of today's cars versus old school cars with points, rotor, condensor, distributor cap, etc./... I'm sure that you will love a power vent unit. (hehehehe)
Maybe someone out there can offer a different view. How about it guys? Anybody PREFER a power vented unit?
Good luck
Charlie
