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.
