It took a day, started at 6am 3 guys, but im also including clean up,
getting parts, planning, etc etc etc and bleeding 22 radiators, Actual
instal was maybe 25 hrs but alot more must be figured in to do and
finish a job. I helped bleed radiators. Heat was on at 6 pm. before they
came I cranked the house to 79f and it never cooled below 66 or so, sun
can keep you warm in daytime.
