When you heat a house, a heat pump collects heat from the earth, air and water, to transfer this heat to the building. While a heat pump is in cooling mode, it just removes the hot air from the interior of a house and sends it outside. Down to work, a heat pumps the same thing all year, but it's just the heat in a different direction, depending on the season. Air conditioners and heat pumps in cooling mode, is both a seasonal energy efficiency rating (SEER as well known), the customers know how much energy each device can be used. After the season energy efficiency rating, ie a large number of lower energy consumption.

The heating seasonal performance factor indicates how much electricity is used by a heat pump during the heating mode. Heat pumps have an external coil, which in turn collects ice in winter. The torch will then be used by the heat to melt the ice and push warm air into your home. This means that in cold climates, Bosch Wärmepumpentrockner can use more energy to heat a house. The name "heat pump" is somewhat misleading for most consumers, because it actually provides for heating and cooling in homes. In hot climates, is highly seasonal energy efficiency rating is necessary to reduce effectively the temperature inside a house. Apart from the fact that with a SEER rating, the pumps and an energy rating of the heating seasonal performance factor (HSPF also known as) scale indicated.
