What Are the Benefits of an Air Heat Pump?


An air source heat pump transfers heat by a process called vapour compression. The heat from air is absorbed into a fluid and is then compressed, raising the temperature. The higher temperature then moves to the heating system. An air source heat pump requires electricity to operate, which can be generated from solar panels. It can even be used off the grid if required. But, it is important to note that these units can only be used in certain climates.

The temperature outside also affects the efficiency of an ASHP. In colder areas, a 2,000-kWh-per-year model can save $300, while an 8,000-kWh-per-year model can save as much as $6,200 per year. The higher the coefficient, the better. In some areas, an ASHP may have a coefficient of performance of two or three, while in warmer regions, a higher value could indicate an incredibly efficient unit.

Installing an Air heat pump (Luftvärmepump) is an expensive proposition, but if you can afford it, there are several ways to finance it. The government has a Green Homes Grant scheme that helps pay for the upfront cost of a heat pump. You can even qualify for seven years of payments through this scheme. However, your future RHI payments will be reduced by the amount you receive from the Green Homes Grant. For a more affordable option, you can apply for the Warmer Homes Scotland Loan.

As the outdoor temperature decreases, the heating requirement of a home increases. As a result, the output of the air heat pump will decrease. This is called the balance point. The temperature of the outdoor air is between thirty and forty-five degrees Fahrenheit, and below it, the house requires supplemental heat. To find out the balance point, plot a line from the heating requirement of the house to the output of the heat pump. The balance point is the location where the two lines cross.

Although some models of air-to-air heat pumps can be efficient, the outdoors section of the unit can freeze. In this case, a defrosting cycle is required, which transfers heat from the indoor coil to the outdoor coil. This reduces the efficiency of the unit. In newer demand systems, defrosting is less of an issue. As the outside air temperature falls below freezing, the freezing tendency will decrease. A decrease in humidity will also reduce the chance of freezing outside air.

A good air source heat pump can save you money on heating bills. The system can be mounted on a wall or installed outdoors. However, the space around the unit is important. There are two types of air source heat pumps: the ductless mini-split and the ducted system. One requires a space outside, the other requires a duct. Air source heat pumps are also often used in conjunction with larger radiators or underfloor heating.

The maintenance of an air source heat pump is minimal, but should be carried out once a year. In general, you should clean the filter, check for leaks, and ensure that the refrigerant level is sufficient. If necessary, you can also clean the system by clearing leaves and dust from it. More complex tasks should be left to a professional.
