Recommended Regulator For An Instant Water Heater And Dryer

Question:

Which regulator is needed for a 120,000 btu instant water heater and a 20,000 propane dryer? Also do I need a separate regulator for each unit or will 1 regulator at the tank work for both units? Both the WH and dryer are in line with one another. Notes 2-100lb DOT specification 4BW240 and equipped with a POL valve tanks

For your water heater and dryer I recommend using the Camco Horizontal 2-Stage Propane Regulator # CAM59333, which is a horizontal regulator with a POL fitting already included, or the MB Sturgis Vertical 2-Stage Propane Regulator # 108220, which is a vertical regulator. You'll want to match the current design of your propane system so that the vent is facing down. The # 108220 will require you to purchase a POL fitting # 204037-MBS separately to attach to your tanks.

I'm assuming since you say you're using two 100lbs tanks you're talking about the the vertical tanks (pictured below) which would require you to use a horizontal regulator. The # CAM59333 outlet is a 3/8" female NPT connector. This regulator will work for both units, which you stated are also in-line with each other.
