After a few weeks with the heat reclaimer on it def. was a good idea. The amount of hot air begin reclaimed from the flu pipe really surprised me. Just the hot air coming out to the reclaimer would be enough to heat two large rooms. My 1600 sq ft basememet is toasty and the overflow spills up the pipe chase and the pipes are toasty.
The trick is you gotta burn hot. I accidentally left for work with the damper almost all the way closed and came home to find the logs unburnt but charred brown and creosote was actually dripping out of the tubes in the reclaimer. What a mess. Also - Ive noticed a slight reduction in extraction due to those exchange tubes being coated with creosote.
When Im burning as hot as I can I have 450deg stack temps below the reclaimer and scalding hot air pouring out of the reclaimer. I dont know what the temps are above the reclaimer. I outta look at at that.
This spring ill take it apart and clean the tubes. BTW they are not perfectly air tight from the smoke stack. If you burn at low temp and put lots of smoke up the chimney. You will smell some smoke in your hot air being blown into the room.
