[Public-List] High Temperature

[John Birch]

Is not a 160 degree thermostat a fairly hot thermostat?!

Nothing wrong with that, it will help prevent valve sticking, but it is only 
60 degrees short of the ambient boiling point.

If you put your hand in 160 degree water it would produce an evil burn. So 
would not the block be very hot to the touch. Many thermostats are closer to 
130, making for a cooler block, but risking valve sticking.

If everything is running properly, where's the problem ?

Just a thought

Best

John
