Oh it gets there after a while, first you have 600 degree flue with the stove playing catch up, then they might be equal for awhile at 600 flue and stove top 600 and after the fire starts to taper off the flue will be lower then the stove top.If the stove can not give a stove temp well above the flue temp it is a poor design period. Sure not on start up but when cruising it should be that way.
Spark,
Serious questions:
Do you think your pre EPA stove was more efficient -> more heat with similar yearly wood consumption? If no, then possibly the increase in stack temperature with the new unit is not indicative of efficiency. An analogy may possibly by, the newer epa stove's are like the new hybrid cars, efficient, but not as much fun to drive and certainly cannot "smoke the tires" like your muscle cars of the '60's...
Are you using the same temp probe setup now that you used with the old unit?
Thanks
Thanks,
Followup ?: The same type and mfg of stove pipe is being used to make the connection to each of the two stoves?
Where I am going with the above question is, ie, if the stove pipe on the old epa stove is thicker or made differently, could it possibly explain the different surface temp readings between the two stoves? If the same stovepipe is used on both stoves, obviously that rules that out.
Different guage, same material/mfg? Heat transfer properties could be different between different grades (and obviously thicknesses) of steel
Nonetheless, I feel your pain when you "upgrade" to a new stove and it doesn't work like the old one... Sadly it seems that way with a lot of things we purchase these days
