i have a potterton 10/16 only got heat upstairs?
my potterton Netaheat 10/16 is only heating upstairs rads and not downstairs, think this is air blockage in system, have drained system and refilled but still the same diagnosis, boiler seems to fire up for a few minutes and sounds ok, but then shuts off and relights again much later, i cannot see a pump anywhere but have replaced 3 port valve, no change, any help greatly recieved.
