Andrew,   Interesting.  I am also running daily testing the PSRU and 
find that the water will only get to 85 C under full power, otherwise 
stable with thermostat at 80C.  Oil however will not go above 60 C.  
Have checked all with a heat gun and is correct.  Why the oil is so cold 
is a mystery, but I am not complaining.  Neil.
