Found them to be completely ineffective, and actually creates "draughty" conditions on the lower floor. As said before, i would recirculate the warm air from the highest point to an accessible point that is as far from the stairwell as possible. You could have the fan connected to a thermostat which would automate it a bit. The radiant heat from a combustion heater should suffice, but this obviously depends on its location. The issue with fans at the top os the stairs i that it does not have a warm pool of air to move to another area - it has rising air and it basically ciculate the air and as you experienced - introduces cold air. If a ceiling fan can be loctaed in an area that hot air gathers - then a slow turning fan in reverse mode can push that air back to where it is more useful. as for temperature sense/on/off heat transfer fans - these are readily available devices from the right suppliers. and yes a combustion heater if very effective at warming the whole area while it is running - but the upper area tend to get a lot hotter than the lower ones.

However, the best solution is to zone off the upper storey so you don't end up heating the entire air mass of the house. Are there any other reasons why the lower storey is cold? Are you losing heat in directions apart from upward? Uninsulated walls? Uncovered windows? External ducts? Unblocked vents? Air leaks?
