The last time I brewed was 2006/7, with a bunch of pretty makeshift stuff. Its going to be a shock to have automated burners !
I would have liked to use a gas control valve from a gas fireplace because they have a built in pressure compensated valve to control flame height. But I couldn't find anything affordable.
Re standing pilot. I didn't want an unattended standing pilot, ie no thermocouple. I have no problem with a standing pilot that is managed by a thermocouple.
