Chubby stove Getting air flowing through house

Hello and happy New year.
I pray this this year surpasses last year in the amount of blessings, piece of mine, and laughter you will receive.

I noticed some people writing that the chubby heat your entire home and keeps it at at least 70°.
I have not achieve getting any other room but where the chubby is located to get to 70° or even passed it.
I have attached a crude drawing of my house lay out. I have a blower. My house is probably 1800 sq ft and only one story. I don't expect the whole house to be heated but I would like the adjoining was to get heated

Thanks for any help
