1. A method of heating and cooling a heating apparatus comprising a heating chamber, the method comprising:
accumulating condensate in the heating chamber, wherein accumulating the condensate in the heating chamber comprises receiving vapour from a vapour supply into the heating apparatus to heat the heating chamber and condensing the vapour in the heating chamber;
monitoring a pressure in the heating chamber;
controlling the pressure in the heating chamber by venting the heating chamber to thereby controllably permit vaporisation of the condensate that cools the heating chamber; and
draining condensate from the heating chamber via a condensate line;
wherein the pressure is controlled to maintain a rate of cooling of the heating chamber within a predetermined range.
