Hi all,i am new here so hopefully i am posting this right ? My question is that I was wondering if i change out my energy king 480 ek furn out to the psg wood furnace,would it be worth it? The reason that i ask is that I have a very bad back but love burning wood and if the caddy would really save that much wood , that would be a lot less stress on the back.The reason i bought the 480 is because I was going to add on to my home but now i am not going too and i think that the furnace might be to much for my home. I have 1650 sq ranch home and the same on the basement witch is not finished,I was wondering if any body had one of the energy knig's ,what kind of burn time did u get? another thing ,would it be worth to install a barometric damper in this furnace? would i be able to get comparable burn times compared to the caddy ?or am i wasting my time on the energy king? One of the reasons that I bought this unit a few years ago is that it was rated at 78 effiency and now when i look at the manual now it show's N/A. Any suggestions would be really great.thanx for this awesome site!
