Is a power-vent water heater right for me?
I'm having a home built and going as high efficiency as I can afford. My plumber makes his money on Bradford White products, so I selected the M1TW40S6FBN though-the-wall power-vent water heater (actually we'll have two of them), because it had the highest efficiency rating. I have plenty of room to vent the water heaters out the roof, again, I only selected this model for its efficiency rating.
But I wonder about it. I mean, if I have a power outage, I assume the thing shuts down and won't heat water at all, right? The power-vent by the way is just for the exhaust. Combustion air is still ducted in from outside. And what about the noise of that blower. I'm a light sleeper - do you think I'll hear that thing?
So I guess my question for any "experts" out there is - based on my application, do you think I've selected the right product, or should I just go with a less-expensive unit and atmospherically vent the exhaust out the roof, and not worry so much about the efficiency ratings?
Thanks for any thoughts,
