Choosing Between a Single and Dual Stage Regulator for 100 Lb Propane Tank and Furnace

Question:

I am using a 100 lb propane tank to feed a 80000 BTU furnace..... tank outside to furnace inside distance will be about 20 ft max Do I need first and second stage regulators or will the second stage alone suffice? Thanks

It is usually best to go with a dual stage propane regulator over a single stage propane regulator as they are more accurate, perform better in the cold, and most can be adjusted. For this, I recommend the MB Sturgis Horizontal 2-Stage Propane Regulator part # 108221. In order to attach the regulator inlet to your 100 lb propane tank you will need the MB Sturgis Sturgi-Stay Propane Fill Hose part # 100019-15 and the MB Sturgis Propane Adapter Fitting part # 402258-MBS. In order to attach the regulator outlet to your furnace you will need two MB Sturgis Propane Hose Assemblies part # 100383-60-MBS. If your furnace does not have a male 3/8" NPT fitting then you would just need to use an adapter.
