Question:

I want to run two On Demandinch water heaters at 38,000 BTUs each. I want to use one 20 lb propane tank. What size regulator do I need? Heaters are less than 8foot apart, main propane line would be less than 20. Suggestions? Thanks.

For the best option, you need a 2-stage regulator like the MB Sturgis Horizontal 2-Stage Propane Regulator - 11" Water Column Outlet # 108221 or the MB Sturgis Vertical 2-Stage Propane Regulator - 11" Water Column Outlet # 108220. The 2-stage regulator provides a more constant stream of pressure which is always ideal for propane applications.
