Hot off the press!
This rocket mass heater is set up to warm your toes by giving you heat
from the floor!
Plus, another innovation is a bypass valve - it should help with
getting fires started at the beginning of the season.

Cool stuff Paul... Our rocket goes through our earthen living room floor after leaving the bench, so I can testify for how awesome a wood-heated floor is.. That bypass valve would come in handy, especially since lowering the exhaust pipe so much can make startups a little tricky at times.
