re: Anyone have propane for their home and have an outlet outside?

VanRich do use LaCox for propane? We have the same set up as you, 500 gallon tank in the ground to run house (range, fireplace) which has it's own regulators. Then we have an outlet stubbed out to run a grill, fish cooker, and crawfish boiler. The outlets for the outside stuff have their own regulator which is at a higher flow. I can assure you the outlet in the ground at my house it high flow.

Using a rocket pot and that outlet I can bring cold well water to boil in 7 minutes. If you have this set up, you just buy a hose from the hardware store and have female fittings on both ends to attach to the stubbed out portion and the other end to the grill, etc. If you need to call me you can come out to the house to see how it all works but it's pretty simple and NO WAY do you want to go back to hauling a 5 gallon tank back and forth to be filled.
