You said that you want to do step unfusion mashing, but that you want to recirculate. So I presume what you mean is that you do not want to do infusion steps, but want to do direct heat step mashing using a heating element, a RIMS.
My system, that I have multiple build threads posted on, is a typical HERMS. I used an electric HLT, a 25' copper coil, a 1500W element in the HLT and a JC A419 to control the temp of the HLT. I use a March pump to recirculate everything (basically the only pump that will do the job).
If you would like to build a RIMS, Id suggest getting a 4500W, 240VAC element at a hardware store, constructing a small (1.5" ID) tube in which to install the element and allow the wort to be pumped through the tube for heating, returning to the MLT. Youd probably be better off controlling it with a PID and SSR/heat sink combo, just because the PID is more intuitive than a typical on/off controller. Run the 240VAC element on 120VAC to make it ultra low watt density, and you are good to go.
4500W element (any hardware)
Rims heating tube (parts from any hardware)
PID (Auber Instruments online)
SSR/Heatsink (Auber Instruments online)
March Pump (Northern Brewer, Austin Homebrew Supply....)
NEMA electrical box for the controls (any hardware)
Do a search here for RIMS Build of HERMS build, you should get a plethera of information.
