Keeping the Living Room Warm

After our last super cold spell a few weeks ago, we learned that sometimes our first floor radiators just dont get the heat spread throughout the rooms like in the bedrooms. We didn't turn the heat up, just kinda dealt with a cold living room (and i spent most of a day in the bedroom!)
But my dad came up with the idea of putting a fan near a radiator to get the air moving. So this morning, I suggested that to Corey, and he seemed a little doubtful. We both kinda thought the fan would have to be behind the radiator to push the air out... and we don't have the room between the wall and a unit. So, before corey left, he took our window exhaust fan we use in the kitchen and put it on top of one of the radiators. 1 hour later, it was shocking how much warmer the dining room and living room were!!
On the plus side, the radiators don't have to kick on as much which may mean in the long run we will save a little gas (maybe it won't matter because of the energy spent using the fan, but I'm thinking less of two evils!!)

Hope everyone had a good Friday- I know I enjoyed yet another "cold" day and lounged around the house!
