Aquastat for hot water storage tank

DonnRDonnR Posts: 2Member
I have an NG on demand water heater with a electric water heater utilized as a storage tank, I am currently using the lower tstat to control the circ pump, the tstat is not reliable, and I would like to replace it with an aquastat. The probe will be going into a 3" well, and I would like the aquastat to turn the circ pump on at 115 degrees and off at 125 degrees.
Any suggestions?

    I dont know the model#, but the clamp on version of the L4006A. Where are you planning to put a well on an electric water heater?

    I am going to take out the bottom element, bush it down and install the well there.
