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 ususally 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.

BTU'S PER HOUR REQUIRED

Cubic feet		Temperature Rise Required (oF)*

10,000	27,000		40,000	54,000	67,000
15,000	40,000		60,000	80,000	100,000
20,000	54,000		80,000	107,000	133,000
30.000	80,000		120,000	160,000	200,000
50,000	133,000		200,000	266,000	333,000

WARNING: When using a thermostat controled heater, its exit area should be protected from personnel and warnings posted of sudden startup.
