Evening all, have replaced 2 blown elements in an old (discontinued) Creda storage heater. As expected the front panel insulation board has disintegrated. Creda service could not help, would obivousely try and flog a new heater. Can any of you learned lot recommend a suitable alternative to this panel around 15-20mm thick.
Many thanks in advance.
ps Creda said it must withstand 176 C
