SIZE AND CAPACITY OF PROPANE CYLINDERS
The charts below show the approximate size of the cylinder
required for these heaters. To use the chart:
1. Select the lowest air temperature expected (at the bottom of
the chart).
2. Move straight up to time of operation desired
(left side of the chart).
3. Read the cylinder size required.
All heaters should have:
HOw MUCH HEAT DO I REQUIRE?
For economy, it is important to match input to that required. But
heat requirements often vary. For example, it usually takes a lot
more heat to get things warm than it does to keep them that way.
Likewise, outside air temperature usually changes during the day
so you may need more heat at night than you do in the daytime.
An approximation of the heat required can be found by using the
chart below.
