Sources: Two resources of thermal energy are most commonly utilized for heating residences with heat pumps.

• Air-Source: The heat pump attracts warmth from the outdoor air throughout the heating season, as well as denies warmth outside during the summer air conditioning season.

It may be shocking to recognize that even when outdoor temperature levels are chilly, a bargain of energy is still readily available that can be drawn out as well as provided to the building. For example, the warmth content of air at -18° C equates to 85% of the warmth included at 21° C. This allows the heat pump to offer a good deal of home heating, also throughout the colder climate.

Air-source systems are amongst the most usual on the market, with plenty of mounted systems throughout the world. 

• Ground-Source: A ground-source heat pump utilizes the planet, groundwater, or both as the resource of heat in the wintertime, and as a tank to deny heat eliminated from the home in the summertime.

These heat pumps are less common than air-source systems but are becoming more extensively used everywhere. Their main benefit is that they are exempt from extreme temperature variations, utilizing the ground as a continuous temperature level resource, leading to the most power reliable sort of heat pump system.

• Sinks: Two sinks for thermal power are most frequently used for heating residences with heat pumps:

Indoor air is heated up by the heat pump. This can be done via:

• A centrally ducted system, or
• A ductless interior system, such as a wall surface mounted system.
  

The water inside the structure is heated up. This water can then be utilized to offer incurable systems like radiators, glowing flooring, or fan coil units through a hydronic system.
