Power Vented Water Heater
 
I am replacing a 15 year old water heater with a power vented water heater. It will be vented out the side of my house. Can anyone recommend a brand/type of water heater, and where to purchase?

I do not need any recommendations on power vented vs. tankless (unless you have a REALLY strong inclination as to why they are so much better); already made the decision to go power vented.

If your mind is made up to go with a wh that requires electricity to operate. IMO, 1 brand is no better than the other

I just don't see the cost savings with the tankless. It seems that the recovery cost between the two would be 10+ years. I don't know that I will be in my house long enough to recover that cost. If you disagree, I would sincerely like to hear your opinion. I almost see the tankless as a "hot, trendy" item more than an actual money saver. But I am by no means at all an expert.

I wasn't talking about a tankless. I really don't care for any gas water heater that uses electricity to operate.

dnt 01-14-2011 10:36 PM

what are you referring to then?

kenmac 01-14-2011 10:38 PM

Your standard tank type Water heater with standing pilot

I appreciate the fact that you are trying to help, but can you just elaborate/tell me your entire opinion without me having to prompt you for all of the information.

If I am to replace my water heater, what is the best way to do so?

My opinion, power vented tank, the cost of and operational glitches, just isn't worth using a tankless.

They do save money. Maybe not as much as they claim but, they do save money. And the bigger difference is, you kinda have control over how much money they save. Just depends on how much hot water you want to use. Lots of people don't buy the tankless water heaters because of the money savings, they buy them for endless hot water. Now I know there are a lot of folks on here that report all kinds of "problems' with their tankless units but, I can almost bet that a lot of it boils down to installer error. Either gas sized improperly or unit wasn't sized for the job. Don't get me wrong, there have been issues with some of the brands of tankless like Bosch, Rheem, Takagi, ect. but Rinnai is the only one that I can think of that I've never ran a service call on that wasn't maintenance related. There is a little more care that has to be given to the tankless units but you can find a good plumbing co. that can flush the scale once a year and check for issues. It's the equivalent of having your HVAC equiptment maintained.
The power vented water heater is the next best thing to the tankless but, you still have to maintain temperature (sometimes uses needless gas and unit will possibly cycle 2-6 times in a 10 hour period even if no hot water has been used depending on the environment in which it is installed). Also, you don't have the endless supply of hot water with a traditional power vent. Unless you want to fork out the $$$$ for one of the fast recovery models (which would put you in the price range of a tankless anyway so why waste the extra space.)
I see where most peoples' logic goes when they see that a standard water heater uses 40.000 btu's and the tankless uses up to 199,000 btus on some models, but it's a more efficient use of the fuel source.
I like State water heaters for the tank-type, Rinnai for the tankless, and I'm starting to consider trying out the Navien tankless units out.
Hope I helped you out.

and Kenmac.... no offense but, you must have alot of power outages where you live b/c that "standard tank-type water heater" is always your answer. But, some people have either permanent or portable generators at that home. Just sayin'. Maybe you should invest.

kenmac 01-14-2011 10:56 PM

You now have 3 different opinions. It's up to you. The reason I gave my opinion on the standard w.h. is, way less parts & less expensive to purchase & have repaired. With tankless you can't just install it and forget it. You will have to perform maintance or the water coil will stop up.

No offence taken. But, If he were in my area I would try to sell him on tankless or power vent so, I could return & perform the maintance & repairs:yes:
I have a whole house generac generator. You posted b-4 me but again less parts to fail

Well, if they keep on trying out all of these FVIR gadgets that have been a plumber's headache since 2007, the "less parts to fail" thing may be a thing of the past as well. Even though it's a simple procedure, even the standard tank type water heater needs to be maintained these days.

You guys seem to be having a great debate, but all of your recommendations combined just leave me back at my original questions.

If I am to purchase a power vented tank water heater, what is a good brand/unit/manufacturer and where does a diy buy one? If it helps, I currently have a 3 person household, (me, wife, 2 year old). Within the next 5 years I will probably have at least a 5 person household.

If possible, please limit your recommendations to the immediate question.

dnt 01-14-2011 11:10 PM

Are you guys on here to help people out or just to debate each other?
