venting a heated basement into drafty bedrooms?

[dwcopple]

So after some advice and a good sale at Menards, I bought and installed a 30K BTU vent-free blue flame nat. gas heater in my basement last week. Running it at lvl 2 1/2 out of five at night it does make the basement toasty and allows the furnace to run less cycles per hour. However the two bedrooms at the end of the hall are much cooler than the rest of the house and I would like to change that. I've already played with the dampers (sp?) and the airflow is good. So is there any downside to cutting in some floor vents in a convenient spot to let some of that basement heat upstairs? What would be the best tool to cut it out? recip saw or jig?

I would do recip/sawzall, make sure you make the hole the same size as a standard vent & don't hit anything (like a joist, or plumbing/wiring). If that doesn't get you enough heat, those little power duct fans would help too!

In my area its a code violation to cut holes in the floor , plus insurance will not allow it, in case of fire, the hole in the floor create's drafts which speeds up burn rate in fires. Many people do it, but is it worth the risk. I'm sure your insurance company would not cover you if the new about it. In our home we have a laundry chute when you open the lid you can feel the air rush past your face.

What is your "furnace" powered by? 30k btu of non-vented natural gas burning is a lot.

Anyway, if you insist on this have you considered getting a cold air return picking up the heat this throws off and leaving the furnace fan circulate?

I seriously doubt if one underpowered vent will do much. You need a circulation path.

Also I am not a fan of ventless
