most people who use the stove as sole source of heat also employ some means of distributing the heat throughout the house.
i.e. fans. and the fan topic and best technique is a topic almost as written about as the OAK topic.
we heat our whole house with the PS50. but it's only 924 sq. feet. and with the narrow layout, the back bedroom needs the fans to get the heat it needs.
there are people who heat substantially larger homes with only pellet heat.

you will most likely get around to the OAK topic too. (outside air kit)
there are new OAK threads at east every month.
this is merely the latest one -

it is generally agreed that an OAK increases the heating effect by allowing the stove to draw it's combustion air from a dedicated direct line in from outside rather than by drawing in home air that has already been heated (and blowing said heated air out the flue) as well as pulling cold air in from every crack or leak in the home's structure.
from your pic, it appears an oak could go behind the stove and not mess up the visual look of your room at all.
cutting another hole in one's house puts some folks off. it's really no big deal.
but maybe sit with the stove for a while and judge what kind of cold drafts you are getting as the stove pulls combustion air in.
lots of folks went to the OAK after a season or two.
proper home insulation and reducing air infiltration are essential too.
and are the best bang for the buck no matter how you heat.
from everything i hear, the CB1200 "heats like the sun". you should be able to do very well with it.
tripp lite makes great surge suppressors. but there are other good brands too.
