I just read the info on their website, interesting, sounds like a more refined burn controller that 'should' take the peaks and valleys off of the all or nothing burn cycles. If you get the chance, please do update on the installation and particularly on whether it lives up to the claims.
I heat primarily with an old Aquatherm model from about 2010 that looks like a barrel on its side, can get 10 hour burns out of it with a full load of good wood and temps in the high teens/low 20's, conditioning about 3k SF. Pleased with the stove, but like you, it wouldn't break my heart to lower the stove's feed bill!
