The great thing about central heating is that it covers all areas – bathrooms, staircases, halls, etc. whereas split a/c units are only in the main rooms.
So, c/h probably costs more (although the split a/c units aren’t very efficient) but gives better overall comfort IMHO.
As for gas or diesel, I think the cost works out about the same although for a large house you need quite a large gas tank. Ours is just 500 litres which is too small for our house and lasts just a couple of weeks.
