The importance of Class H insulation on the

Similarly, a Class H system operating at a Class F temperature rise will provide the same life expectancy as a Class F system operating at a Class B temperature rise. Moving from an insulation system Class F, with a hotspot of 140°C, to a hotspot of 160°C, the S9 ratings are able to be increased by 7% - with an improvement in design of insulation lifetime of around 20,000 hours.
