The increased cost and scarcity of all fuels have affected the greenhouse owner as badly as any segment of industry. For some, crops have been damaged or lost. For others, it has reduced the margin of profit. Growers, manufacturers, suppliers, horticulturists, engineers and many others have studied the situation thoroughly in order to come up with viable solutions and alternatives for conserving fuel.

WHAT IS A HEAT PUMP?
A heat pump is an electrically-powered refrigeration cycle device which is capable of providing both heating and cooling to a residence. In the summer, it operates like an air conditioner by "moving" heat from inside the house to the outside. In the winter, the refrigerant flow is reversed, "moving" heat into the house by further chilling the already cold outside air and transferring the heat gained in the process to the inside.

Below-grade living is not new; prehistoric man instinctively sought out subterranean shelters for protection against his enemies and extreme environmental conditions. Historically, the designs of below-grade enclosures were determined by such factors as availability of building materials, climatic elements, defensive needs, ceremonial beliefs, and cultural concerns. Contemporary use of underground house components includes basements, cellars, and other similar spaces. In most cases, however, individuals occupying below-grade quarters have either had access to an above-grade structure or have considered such quarters as temporary. The notorious basement that is wet, cold, and without adequate lighting has given an undesirable image to below-grade …
