I have intermittent pilot low pressure Honeywells; spark ignition on the kettle, hot surface on the HLT.
The spark ignition is a PITA, when it arcs the Brewtroller goes nuts; random characters on the display, 1 wire sensor net shows impossible readings, sometimes the whole board freezes up and requires a power cycle.
Not to mention the need for yet another box to house the valve controller.
I've seen talk of people creating Faraday cages, shielding all their cables and all sorts of craziness that I have yet to try.
The hot surface just works, no drama. Plug 24VAC in and go. I would encourage anyone looking at going this route to save themselves the problems and go hot surface from the beginning, especially if your going to use a controller like Brewtroller or BCS.
