I will be doing some work in the laundry/heater room shortly, including installing a new natural gas hot water heater.
At one time I had no problem doing my own plumbing "sweats", but, for now I think I will call a real plumber. I have some additional work that needs done, and a *real* plumber would be oh so helpful.
I am in Willow Grove PA in case someone who is reading this wants to volunteer! (give me to spring to move some stuff out of that room prior to)
The question I have is when upgrading my 40 gallon unit, I came across this $2000 96% efficient hot water heater by AO Smith called the Vertex 100. Sure it's pricey, but it looks like it could almost take the place of my baseboard heater unit by some of the advertising I have seen on it.
A couple of questions, specifically.
Are the "guts" of this unit significantly different than a standard hot water heater (we're talking gas here, not electric)? I think so, but, I don't know.
The chimney on the unit today is a 3" stack going into an 8-10" chimney also serving the purpose of venting the baseboard hot water heater, or, err, heater. One guy I called, locally, told me that Vertex would have to vent to an outside wall. Period. Huh?
And lastly, I made the part up about it replacing my heater-heater, but it does say that it can run some radiant heating systems as well as provide all the hot water I need. Anyone care to state real world results?
And, getting back to the original question; hot water heaters come in "residential" and "commercial" but I am having a dickens of a time trying to figure out --- besides warranty and price --- what makes them different.
Thanks again...
