In that case, they're *probably* hotter than 70 degrees. How are you measuring flow temperature?
Ok. I now have a new battery for my digital multimeter.
Got thermal paste for the boiler thermostat suppository thingy.
Took temp at suppository with DMM. Goes to 82 deg C before burner cuts out.
Tested flow at site where overheat thermostat is, 77 deg C.
Have drained system and added Fernox cleaner. Running now.

Fernox cleaner in system now.
Flow up to about 80 deg C. Return about 70 deg C

No thermostatic mixing valve then?
