In the cooling cycle of a Heat Pump , you are removing hot air from inside the house and sending it outside. You can feel the hot air outside, over the condenser fan motor.
Heat pump heating mode
In the heating mode of a Heat Pump the refrigerant cycle is reversed and you are now removing the heat from the outside and sending it inside the house. You can feel the cool air outside, over the condenser fan motor. When temperatures go below 40 degrees Heat Pumps labor in producing heat and must use back up electric heat strips. Heat strips cost 3 times as much to operate as a Heat Pump when producing heat.
Heat pump water heaters
A water heater that uses electricity to move heat from one place to another instead of generating heat directly.
Heat rate
A number that tells how efficient a fuel-burning power plant is. The heat rate equals the BTU content of the fuel input divided by the kilowatt-hours of power output.
Heat recovery ventilator
This device bring fresh, outside air into a home while simultaneously exhausting stale indoor air outside. In the process of doing this, an HRV removes heat from the exhaust air and transfer it to the incoming air, pre-heating it. This allows for the reclamation of much of the energy that otherwise would simply be vented outside. The end result.
Heat register
The grilled opening into a room by which the amount of warm air from a furnace can be directed or controlled; may include a damper.
Heat sink
Often used in electronics where it is necessary to keep heat from sensitive circuit parts during soldering, this metal shape has good heat conductivity to draw heat away from an area.
Heat source
A body of air or liquid from which heat is collected. In an air source heat pump, the air outside the house is used as the heat source during the heating cycle.
Heat storage
A device or media that absorbs heat for storage for later use.
Heat storage capacity
The amount of heat that a material can absorb and store.
