Like many people we have gas central heating. What I often wonder about is trying to make it work better. What I am thinking about is how the heat fills the room. So the heating comes on, the temperature in the radiator rises and cold air at the bottom rises through it and continues on rising towards the ceiling. This continues until the air at the level of the thermostat has reached it's setpoint and it turns the heating off. This means the air above it is hotter than the setpoint and that below it is colder.

I did think that a ceiling fan might help but the air it pushes down wont go far unless the fan is quite powerful. So what I'm wondering is would it work better if there is a fan below the bottom of the radiator blowing the cold floor level air up through it. This would warm a greater amount of air per minute but it would be cooler and the fan would be constantly dragging the colder air down thus evening out the temperature from ceiling to floor.
Does that sound practical or can you see some error in my reasoning?
