Looks like mine is 65c,Nice one Terry.
Might be worth adding that it is not uncommon for a fire valve to be fitted rated at 65c.
Most boilers require a 90c fire valve, so might be worth checking the brass valve body, where the temp rating is marked.
Boiler still not right

Seems to trip when high demand is on the boiler.. Anyone any ideas what to test now??
