Air Source Heat Pumps A Guide to Air Source Heat Pumps The air source heat pumps are an excellent choice to render year-round heating and cooling comfort to your home. It is not only efficient and reliable but also relatively affordable when compared to other types of heating systems. Whether it is for commercial or residential purposes, air source heat pumps serve as a best choice. However, it is most suitable for houses or buildings with limited ground clearance.

Functioning

An air source heat pump primarily works on basis of the principles of thermodynamic, i.e. to transform the latent heat contained in the outside air to heat energy, which in turn can be used for heating building. If the air source heat pump is in heating mode, it absorbs heat from the external temperature and transfer it to the indoors to provide warmth to your building. But when it is in cooling mode, this type of heat pump expels the heat from within the building to render maximum coolness to your home.

It carries out its functions using prime three components, such as evaporator coil, compressor and condenser coil. The prime function of evaporator coil is to extract heat from the external air while the compressor pumps the refrigerant gas via the system squeezing it until it reaches a temperature between 35 and 40 degree Celsius.

Efficiency

The efficiency of an air source heat pump is determined on the basis of its COP (Coefficient of Performance). For instance, if the COP of your heating system is 3, it means your heat pump generates 3 units of energy for every one unit of its electricity consumption. The higher the COP, the more efficient and reliable your heat pump will be.

Different Types of Air Source Heat Pumps

There are two different types of air source heat pumps: Air to Air Heat Pumps and Air to Water Heat Pump. Air to Air heat pumps are the most commonly used air source heat pumps. A specialty of air to water heat pump is that its functioning is based on the hydronic heat distribution system and it can functions more effectively in lower temperature.

      These are a worthy investment, although its a shame they were dropped from the new RHI initiative.

        It is worth noting that this only applies to the RHI in the UK. In the US, these systems can qualify for the following Federal Tax Credit if the requirements are met.

        Tax Credit Amount: $300

        Requirements:

        Split Systems:
        HSPF >= 8.5
        EER >= 12.5
        SEER >= 15

        Package systems:
        HSPF >= 8
        EER >= 12
        SEER >= 14
