Interesting I'd not heard of this and could be useful in one room.

When I had high ceilinged rooms I used foil behind the radiators, usually curved under a window sill, which sent the heat to the room and not the wall or ceiling.

The difference in temperature in the rooms was considerable despite what I was told,

Just done it in my bungalow and increased the room temperature from me wearing thick fleece to thiner sweaters and legings

It doesn't look pretty (I'm working on that) but fewer people calling in winter. And it's more about me being warm and spending less than what they think of the decor.

In my last place with high ceilings it reduced the amount of gas used too.

I don't think your average ceiling fan or pedestal fan will help, they go much too fast and will make you cooler not warmer.

Not in my experience & we run 3 ceiling fans this time of year ( 1x 54" ,2x 42" ), all on low speed & in reverse so as to push warm air across the ceiling & down the walls.

These fans along with a couple of small portables mean we can heat our 3 bed Victorian terraced with  9' ceilings enough for the two of us from one log burner . We also find the house suffers less from cold draughts when the fans are running.

if you have a fan blowing air past a radiator, it's going to heat the room up more but it certainly isn't going to use less gas, it'll use more!

But the main stat is in that room so surely the boiler will go off sooner? 

Do you have thermostatic valves in the other rooms?

Yes I do.

Yes I do. 

Then the fact the main stat is in the big room doesn't matter.

We used to have Myson Super Envoy fan-convector heaters, which solved this problem in a visually appealing package.  The current model is a Myson Lo-line, albeit that it looks a bit more industrial.  The Grant Solo Compact or Compact Max is probably a better option, but as you say, they are not cheap. 

I'm not sure why these fan convectors are not more common as they work exceptionally well where you want to heat a large space without taking up a lot of wall with radiators.  They apparently are also a good option for low-temp circulation such as with heat-pump systems.  When I was recently trying to source the Grant Solo, both my local Grant agents were unaware of their existence and had to look up the catalogue to confirm that such a beast existed. 

The downside to using this to replace an existing radiator is that the pipe-run will need a bit of adjustment (inlet and return are both at one end of the unit) and you will need to wire-in a switched spur connection.

I have something similar in my kitchen - There, it is called a "plinth heater". Similar design and the same principle as a fan-convector heater. Perhaps the reason they are not so common is the cost. A plinth heater is around £200 whilst a conventional radiator would be £50.

Tbh, heating unusual shaped rooms which just have one conventional paneled radiator Could be challenging  

Heat rises with convection and can just filter to outside or be physically blocked resulting in loss of the previously warmed air returning to the radiator to be reheated to make the air warmer  and keep doing that cycle.

Usually make a heat loss calculation for the actual room, then a calculation for the mezzanine area and add them together. Seems excessive but it works though one conventional paneled radiator may be the worst heat emitter.

So much can be done to get the existing ch system to supply comfortable heating or just use a few electric oil heaters. When seasonally cold.

Strategically placing extra radiators or ufh would be something to consider after a site survey !

Happy heating

Indeed.  But isn't it funny that most folks think nothing of adding a couple of plinth heaters (which in many cases are never used) onto the cost of a new kitchen, but wouldn't do the same for a central heating system?  In actual fact most folks would never even be offered the option of fan convectors on their central heating system as the heating engineers and suppliers seem to be unaware of their existence!
