I let the water cool right down to around 25c Twice, then turned immersion back on, and both times the max temp the relay reached was 34c after approx 1.5 hours !
So either my extra ventilation and thermal past has worked superbly or as I think more likely the failures have been caused by internal faults in the SSR and the heat that caused them to melt down was caused after the fault and was not the cause. ??
