I have a very old home (1846 Cornish Miners Cottage) located in S.W. Wisconsin. I have been repairing and restoring the home for several years and I am now getting ready to up-date the heating system (such as it is.) It is currently heated with a old Heil-Quaker natural gas vented heating stove model: RVFA-708-1 Serial #F13113 BTU/Hr = 22,000 min & 70,000 max. There is no crawl space under the house or way to duct a conventional furnace. The house is aprox. 780 sq ft. and is now moderately insulated. I am considering installation of a modern blue flame gas heater to take it's place but don't know what size (BTU) I will need. I have been looking at 30,000 BTU ventless models but don't know if that will be enough. Any information, thoughts or advise will be appreciated.

Thanks,
