 It sounds to me that you have an airlock in the heater radiator. I am not
familiar with the TR3A pipe set up but in theory the idea is to bleed the
system of air. Many French cars have a bleed unit fitted exactly for this
purpose. It is just a matter of running the engine until water flows from
the bleed screw. As to the practicalities of utilising this concept I would
have to leave to your imagination.
You could try disconnecting the cold heater outlet pipe in the engine bay
with the engine up to temperature and running. When hot water flows
reconnect. Tip: wear gloves the water should be hot.
