I have attached some info below regarding the gas consumption of the Excel RV Tankless Water Heater part # EX93FR.

A person can take 133 - 5 minute showers - with a 20lb tank

A family of 4 can take 5 minute showers for a month.

Calculation
1 gallon of Liquid Propane Gas (LPG) converts to 36.39 cubic feet of Propane Gas , there are 4.6 gallons of Propane in a 20lb bottle.

167.4 cubic feet of vaporized propane in a 20lb bottle.
There are 2,523 BTUH in one cubic foot of propane
This means a 20lb bottle of propane has 422,350 BTUH
The Excel Water heater consumes 38,000 BTUH
This means you can run the Excel Water heater for 11 hours
