Wow...I was just thinking about something last night along these same lines. Foe example, I wish that "I" had read this forum all the way through along with the arborist forum, prior to purchasing my Shaver. I still may have bought the Shaver, BUT.....I would have known ahead of time what modifications I was going to have to make prior to firing it up. So I will add my $0.02 to the soon to be growing list:
1) Look at literature/website for perspective OWBs and read their charts for square footage of your property and to what size OWB you really "should" have. All too often folks buy OWBs that will "just barely" meet their needs and wished in the long run they would have gone that "one size up."
2) See if there is an "option" list for the OWB you are interested in. I highly suggest these options:
a) IF a larger fire box door is available, opt for it as it will ease trying to get a bug piece of tree into a standard size opening.
b) If a larger blower motor ( for those OWBs that require one) is available, opt for it.
c) If an auto damper (positive closure) is available, opt for it. This will work more efficiently that not having one, plus less hassle.
d) If an Aqua-stat or Ranco T-stat is available, opt for it...as you can set your burn times along with seeing what the temperature in in the water tank.
e) If additional insulation is available, opt for it.
4) Compare fire boxes...not all are as they are claimed to be.
5) Read over warranties very carefully
6) Consider a company that has EXCELLENT CUSTOMER SERVICE "before" "during" and most importantly "after" the sale.
7) Avoid companies that only want your money and the heck with you "after" they have your money....and just by reading this forum one can gather which companies these are.
Dealer location. This IS important because it's easier dealing with a local dealership versus one that is 500 miles from you.
9) Return policy...yes I know this "should" be under warranty info, but sometime is not.
10) BBB (Better Business Bureau) Check this site for whatever company you decide to go with. One can learn much just by going here.
11) Overall construction of OWB...stay away from "shoddy" construction if at all possible.
12) Are you going for the overall quality of furnace? Suggestions from friends? Or wanting to save money going with a more simple OWB versus one with all the bells and whistles?
These are some of my suggestions. Surely someone with more skills in writing can make my suggestion sound smoother than I did...but you get the gist of my suggestions.
As I said in the beginning...I wished I had come to this site before making my purchase. There "really" is much to consider before making the leap in buying an OWB.
And for my own understanding...just what in the heck is a "sticky?"
