Heat Absorbing Glass
Window and skylight glass that contains iron to absorb heat, thus reducing the heat transmitted through the glass.
Heat Collector
Also referred to as a solar collector or solar panels, it collects heat from the sun, which is turned, into energy that is used most commonly to heat water for the home or pool. There are different forms of collectors.
Heat Exchanger
Apparatus, which transfers heat from one fluid to another in cooling or heating systems. Air conditioners use both a condenser and an evaporator. Steam and hot water radiators are heat exchangers, which are used to produce heat.
Heat Gun
Device, much like a hair dryer, which changes electricity to heat with a blower to aim that heat at a surface, to soften paint for removal or to accelerate drying.
Heat of Fusion
Heat needed to melt a particular solid. For example, gold becomes liquid at about 2,000 degrees F and iron at 2,730 degrees F.

Heat needed to turn a liquid into a gas.
Heat Pump
Apparatus that can heat but also cool by changing its cycle and using a refrigerant, a compressor and heat exchanger.

  2. The extent of horizontal displacement caused by a fault in the earth.
Heavy Timber Construction
Use of heavy timbers, connected with bolting and metal plates at their intersections, for main structural pieces in construction. The heavy timbers carry the structural load so that studs are added to form partitions and not for weight bearing.
Heavyweight Concrete
Used for radiation shielding, the concrete is made dense by addition of a heavy aggregate. Regular concrete weighs approximately 150 pounds per cubic foot while heavyweight concrete weighs 400 pounds per cubic foot.
A measurement, equaling 2.471 acres or about 107,637 square feet or 10,000 square meters.
Metric unit of weight, which equals 100 grams or 3.527 ounces.
