This is a gas appliance that vents to the room and relies on a sensor to turn it off when the CO concentration gets high enough to kill you so you cannot use it for continuous heating,

This appliance is so dangerous it cannot be installed in a bedroom in my state but I would not install in any room.

Also it will produce excessive water vapor and other by-products that can cause respiratory problems.

I know you are finishing a basement. In order for the space to be habitable and safe for you family it should have clear openings to the exterior that equal at least 4% of the floor area.

For heat you might be able to extend the house heating system if its large enough. Electric heat is good if the space is well insulated and will not be used for long periods of time. A direct-vent fireplace will also work.

Ok good to know. Thanks RES. I’m glad I can consider all these options

The stove you are considering has a 30K BTU input. That by itself should not be an issue for combustion in a 900 sq. foot space. It may be an issue if you also have a furnace and hot water heater in the same space.

The heating requirements for a basement which is mostly underground is much lower than the rest of the house. You should be able to use the 20K BTU version of this stove. Ask your code official what are the venting requirements for gas appliances in basements.

Thanks Mike. Yeah it would be installed about 10 ft away from my water heater and furnace, which would be in a different room.

That isn’t even allowed in a lot of jurisdictions because it’s so unsafe. You need to rethink the HVAC for the whole home with the aid of a pro.

I agree, unvented=poor choice. Too many consequent problems and things to worry about. Anything else would be better,

Adding humidity (with an unvented appliance) into a basement, the part of a house that most typically has humidity problems, makes no sense at all.

If the furnace is close buy then you should look into adding 2 or 3 supply vents for the basement Do you know how cold your basement is during the winter? Do you plan to add insulation?.

Yes I plan to do 2 inch XPS foam board insulation R10. I will be contacting HVAC companies. But just wanted to get 3rd party advice as well

This would be a direct vent system. I’ve come across this one which I could simply vent out.

Ventless heaters are fine for occasional/ambiance heating but not the best choice as a sole heating source. A direct vent heater as shown above is your best bet.

Thanks. I think the DV gas stove is the most economical as of now since i received $5.5K quote to install an electric wall unit which would also do cooling and $7K for a natural gas HVAC system. I don't need the additional cooling for the basement as it stays pretty cool down there year-round. Also, I don't want to extend ducts from my main system since I don't want to have to heat my entire basement when it's not in use. My father has installed these gas heater stoves before which would run me about $3.5K.
