What are peoples' opinions on flat panel heaters? I saw a largish one
in Wickes but it was only 900W and didn't say how it worked (oil,
wire element, etc). I also saw a smaller DeLonghi one in Homebase
that was oil-based but that was just 600W.

900w or 600w is 900w or 600w no matter what type of heater. They all
put the same amount of heat into a a room, which is entirely dependent
on the wattage.

The only variation is the type of heat they produce. Fan heaters start
to warm up fairly quickly and distribute their heat around the room
well. Radiant type heaters are good for localised heating (warming
your knees). Oil heaters are slower to warm up and much more gentle.

Oil heaters also retain their heat after turning off rather like a normal
radiator, so you can get a more constant heat rather than non-oil based
where when the thermostat turns it off it stops putting any heat out into
the room (as the element is no longer heated) and (depending on the room)
the temp can drop quite quickly again before the thermostat kicks back in
again.
