They can be arranged in series or in parallel depending on the heating requirements.

Computer simulations rate the heating requirements to between 10 and 20 kWh/sq.

"Because it is winter, they will need special heating requirements," he added.

For example, if a day's average temperature is 20 degrees, then the heating requirement is 45 degree days.

Will using a dehumidifier save more energy by reducing heating requirements than it uses to dry the air?

The newspaper probably lists a figure in its weather report for "degree-days," a measure of heating requirements.

If a day's mean temperature is 15 degrees, then the heating requirement is 50 degree-days.

It is claimed that such systems satisfy heating requirements at a reasonable cost.

A proper installation considers the house's heating requirements and uses the natural movement of heat and air to get the most from the stove.

"The heating requirements apply to the entire apartment, including the bathroom," he said.
