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.
