How do I estimate BTU usage to properly size new gas line?
The size for the range goes back to your cooking style if you use 2 burners all the time or are like my wife uses 2 burners the griddle and one of the ovens at the same time you add all that up but remember you probably won’t be grilling at the same time or the furnace may not need to turn on as often while using the range. It won’t hurt to size everything for maximum flow but the pain may be in the check book when you find you need 1-1/2 lines to do this but only really need 1” for actual use. So if you use all the burners and oven at the same time add them in but then think will you be grilling outside? Or will the heater need to come on? And go from there.
