I may have found a source of (new) circular heater elements (ironically the company is called 'Holdens'. Go to:
http://www.holden.co.uk/hvc-home.htm
and then navigate e-catalogue- heaters/electric fans- circular heater elements. Part 080.506 looks like it might work for warmaride type heaters. Trouble is they are expensive and won't reply to my e-mail re. size, operating pressure etc. Anyone visiting the UK?
