Hello Hearth! Just snatched the last Apex-CBT from my dealer for a steal, actually cheaper than a PSG Caddy, i am very pleased with my purchase financialy but i have been searching internet for actual reviews of this furnace without great luck. I know it uses the catalytic combustor of the King stove, and it looks very well built and rugged with a 5.7sq feet firebox . My house is about 2000sq feet without the basement, construction is 1880 but the basement is 1970. There is little to no insulation in the attic... i knew it was a problem when we bought now i know it's a priority in the spring. This is our first winter in this house and i have been burning SO MUCH wood in this old smoke dragon in the basement. We had a weekend with temps down to -22F with a lot of wind and the old stove in the basement and the VC Intrepid on the main floor were running full blast and the house was not really that hot. I burned a whole face cord in two days in those stupid stoves. Any Apex owners here want to share their experience with this furnace? I know it needs a 7'' flue but i have a masonry chimney and was planning on installing a SS liner anyway. I'd also like to know how fragile it is to semi-seasoned wood? This old smoke dragon burned everything i had mostly. I'm wondering if i should keep the cord i have left for next year. Hopefully next winter will be much more cozy. JP Here's next years wood, buried in snow, these are 16' lenghts of maple and cherry mostly i think.
