You will always have one (or maybe two) pressure regulators between tank and
appliance.

Out here a lot of people have the 100# tanks for cooking/heating. You can get
them refilled with a truck.It'd be interesting to know what pressure those
heaters want though. A stove wants low pressure, some heaters want high
pressure. Makes a big difference in how you work your install.

More shop propane questions. I am not sure what the PO of Okie acres did, i
see no evidence of a big propane tank being installed on the property. There is
a gas line connection at the back of the shop and I suspect maybe they used
those 100lb tanks and just took them down and filled them. Would this be the
way to go or get a big permanent tank? Will these 100lb tanks run these big
overhead heaters? I would probably only actually run one of them, not both at
the same time.
