Watch that Circ Pump!
« on: January 06, 2009, 09:23:17 AM »

Hey,

I discussed my setup with a heating specialist at Kerr Controls who did some research which lead him to believe that a lot of people were installing wet rotor circ pumps on the backs of their outdoor wood furnaces and these were burning out quite readily due to the head pressure not being what the pumps were designed for.  The lower head pressure was causing the pumps to cavitate and burn out.  He suggested I use a dry rotor pump to avoid this problem and it has worked well for me!  Of course these pumps cost more!
