After a couple of weeks more of driving and believing their isn't any air in the system and messing with the temp settings I've discovered a couple of things.

First if I'm stationary for a couple of minutes the temp Rises to the middle and doesn't go higher. After setting off and a few minutes later it will drop again to where it usually sits. While stationary the warm air does become warmer then cools a little when moving.

Second thing that has become apparent is that the coolant level warning came on just after I bought the car. Thinking nothing of it as I just out about 100 miles through it I just topped it off and all has been well. Now I'm not sure how much the level drops under pressure but the warning came on again going down hill around 70mph. So pulled over and the level was below minimum. So I carefully released the pressure over a couple of minutes and the level rose almost to max.

Any clues apart from getting it pressure tested as I can't find any visible leaks.

Car is also running on lpg if that helps.
