heres my review so far :well after a long tedious install process and browsing on here i finally got my new Englander 28-3500 addon furnace broke in and running .first i must say previously i used forced air 110,000 BTU oil heat for my 2,000 sq ft split level .it has not been good to me i nthe past and the price to operate it was ridiculaous on cold blustery days there was noticable cool areas and my lower basement level was always still very cool around 60 degrees at best .Now that im getting used to this whole wood thing im realizing i have been missing out all these years on the tremendous heating and cost savings of hard wood,i will never heat with oil again .i have been burning large ash splits and this englander addon model is the big utility version (home depot 1389$-10% was 1250$ ) that handles nearly 26 inch big fat lunkers with the 850cfm blower theres really no need for using the existing forced blower unit ,long story short im sweating !,it puts out ignorant blowing inferno with ease,I imagine it could easily heat a 3,000 sq ft house im sure , im talking every molecule of my house upper level and lower is currently 90 degrees and out side temps are only high 20's with high wind and snow flurries ,so warm in fact we are wearing summer clothes around the house , i have to open the windows/doors just to get it down in the lower 80's to stand it ,this is a strong dry heat that i have never felt .the stove is rated at 80k btus i think and is definitly doing double what my 110,000 oil furnace couldnt dream of on its best day .Im very happy with my purchase ...the englander isnt the prettiest ,its not the fanciest i n design but its economical ,completely practical for its intention cake to use and will bring your house on very cold nights up to blistering tempertaures of warmth with even a small load (Im a total newbie getting long all night burns already! ) .seems i have really taken to this woodburning bug now ,funny thing is i notice things i never did like other peoples wood piles ,fallen unclaimed trees and if house chimneys are smoking alot .love the smell too .I want to thank the members of this forum for all the handy tips i have seen on here and hopefully ill be able to contribute more in the future .
