RE: [NEDRA] Pid for a heater control?

Has anyone tried using an industrial PID and SSR relay as a controller for an electric heater? Ebay has boat loads of em between $30 and $200.
 
I'm thinking about trying it. I'm using a hot water heater element in a fabricated stainless tank and small pump to circulate the hot water through a normal heater radiator (not a ceramic heater and fan). Looks simple enough and I think a PID would work with either style of heating arrangement. Any thoughts, additional ideas?

... Jack Were you using DC rated SSRs? I'm planning on trying this also, but my SSRs are DC rated well above my pack voltage. The current rating is marginal,...
