The T5 has been remarkably efficient and consistent so far. Last night it was breezy and 8 degrees. At 6PM I raked the coals forward then packed the 2.0 cu. ft. firebox full. I came downstairs at 4AM and found loads of coals and the blower purring happily along. Stove top was around 250 degrees. The temperature in my home was 69 degrees both up and downstairs. I raked the coals forward and loaded the stove again and had secondaries lit in less than 10 minutes.. Lowered the air all the way down and headed to work..Getting 10 hr. burns with the T5 with good dry hardwood is very easy to do and feel I could probably go 11-12 hrs. easily. Interestingly wind seems to have little affect on my burn rate. I have no idea why this happens but it's a good thing! On another note I replaced the 3 back pumice firebricks in the back of the stove with hard ceramic bricks from TSC and I haven't noticed any difference. The bricks in the back take much abuse than any of the soft bricks so I will leave them there and will keep the rest of pumice bricks for the sides and bottom.
