Propane Gas Supply Sizing

The vaporization of propane is affected by several
factors: the surface area of the container, the liquid
level of propane, temperature surrounding the
container, and the relative humidity. All of these
factors are specifi c to a site. Therefore, a degree of
experience and judgement is required to select the
proper propane supply.
Although experience is the best guide, the
following recommendations can be used as a
starting point. The table is based on experience
in northern climates where cold weather and high
humidity are prevalent in the winter. If more or less
favorable conditions prevail at a specifi c site,
adjustments can be made on the basis of
experience.
Recommended Propane Gas Supply - Cylinders Required Per Heater
Average Temp º F / ºC
40 lb / 18 kg TS040 = 40,000 btu/h
20 lb. / 9 kg TS040 = 40,000 btu/h
*Cylinders must be manifolded together to allow simultaneous vapor withdrawal from all cylinders.
Average Temp º F / ºC
40 lb / 18 kg TS040 = 40,000 btu/h
20 lb. / 9 kg TS040 = 40,000 btu/h
Run Time calculations are based on starting with a full tanks (s)
** The use of a single 20lb. tank is not recommended below 30°F/-1.1°C.
Due to the potential lack of vaporization rate of the liquid fuel.
