So as the title says I'm looking at building an automated propane fired system with the following craziness in my head...
Using say a water heater gas valve (with propane orfice) and an electronic ignitor on my HLT and a Johnson/Penn thermostat (like the one used to convert my chest freezer to a kegerator) with the probe mounted in my mash tun recirc line that goes through the coil in my HLT.
So....the Johnson/Penn would monitor water temp coming out of the MLT, temp drops sends signal to electronic ignitor/gas valve lights pilot then main gas.
When starting to fly sparge just raise the temp on the thermostat and BAM!!
Any thought or suggestions about this setup would be great. I would like to hear from someone if they have done something like this.
Sure can tell that I'm an HVAC Tech....huh!!
