Air Source Heat Pumps from sprsunheatpump's blog

An air source heat pump uses a condensed form of vapor-concentrated air to generate heat. The condensed air is in the form of a very hot liquid which is drawn into an air handler where the temperature is regulated and the liquid is then compressed further. Air source heat pumps are therefore often compared to water heaters, albeit the latter uses a solvent refrigerant rather than an oil solution. The condenser is however not involved in generating the heat but merely collects the heat which is then dissipated.

An air source heat pump also uses the concept of conservation of energy. Since they use no electricity, they are completely free renewable. There is of course a maintenance cost associated with the system, but these are minimal and well worth the initial investment. The only additional energy cost that air source heat pumps have is the cost of their power supply, and this is minimal too as most systems can function on solar or wind energy.

The only real drawback of an air source heat pump system is if it is situated in a location which experiences either a high or low seasonal temperature. In these instances the pump may require constant power backup to ensure that it works at its optimum level. A copier-tread thermometer is commonly used to monitor the temperature. Once the reading on the cop shows the temperature has dropped by 5 degrees or more below the normal temperature, a backup power source should be applied so that the cop is able to continue working at full capacity without risk of damage.

Another major advantage of air-source heat pumps is that they provide permanent as well as temporary cooling. During the summer months when temperatures are higher, air conditioners are used. On the other hand in cooler climates, air conditioners are used only during the winter months when temperatures are lower.

However, one of the primary disadvantages of air source heat pumps is the amount of electricity required to run them. The electricity generated needs to come from some form of renewable energy, which may not be readily available. Even if the requisite energy sources are discovered, the amount of electricity produced is likely to be considerably higher than needed. Additionally, the ongoing cost of production can prove to be quite high. For this reason many homeowners are turning towards purchasing a second hand unit.

When installing an air source heat pump, there are a few advantages to owning a second hand model. For one, they provide the advantage of being cheaper than buying a new unit. Moreover, in terms of maintenance, they are considered to be low maintenance devices and are usually suitable for low altitude applications.

Another advantage of using an outdoor air source heat pump rather than a new unit is that they do not have the annoying tendency to suddenly turn off and on. As a result, they can be used in areas that do not get unusually hot or cold temperatures. This means that they can be used in a wide range of situations, including applications where outdoor temperatures are frequently controlled to prevent damage to stored items.

The two main types of air source heat pumps are Ground/Water Source Heat Pumps and air to water. A ground source unit generally involves excavating a hole in the ground large enough to accommodate the pump and then placing a filter inside to capture debris. Water is then added to the excavated hole. An air source system involves installing pipes into the ground that draw in fresh air and then pressurize the warmed air to move through a larger pipe. There are other types of air source heat pumps but these two main types are the most popular.
