Air Source Heat Pumps Explained - What it is, Why To Use and Benefits

Air Source Heat Pumps Explained - What it is, Why To Use and Benefits

An air-source heat pump may offer your house with efficient heating and cooling. An air-source heat pump may give up to three times more heat energy to a residence than the electrical energy it uses when built appropriately. This is feasible because, unlike combustion heating systems, a heat pump transfers heat rather than converting it from a fuel.

 

Air-source heat pumps have been utilized in practically all sections of the United States for many years, with the exception of locations that have had lengthy periods of subzero temperatures. However, in recent years, air-source heat pump technology has progressed to the point that it may now be considered a viable space heating option in colder climates.

Types of Air Source Heat Pumps

The many types of MCS Approved Air Source Heat Pump in Buckinghamshire are detailed in the following sections.

Short-Run Ducted vs. Ducted vs. Ducted

Only a three-inch hole in the wall is required to connect the outside condenser and the indoor heads in a ductless system. In addition, ductless systems are frequently implemented.

Packaged vs split

Most heat pumps are split-systems, with one coil on the inside and one on the outside. The interior central fan is served by supply and return ductwork. Both the coils and the fan are frequently located outside in packaged systems. Ductwork that runs through a wall or roof delivers heated or cooled air to the inside in Approved Electric Vehicle Installers Buckinghamshire

How do the Air Source Heat Pumps work?

The refrigeration system of a heat pump is made up of a compressor and two copper or aluminum coils (one inside and one outside) with aluminum fins to enhance heat transmission. In heating mode, the outer coil's liquid refrigerant absorbs heat from the air and evaporates into a gas. As the refrigerant condenses back into a liquid, the heat is released from the indoor coil. A reversing valve near the compressor may shift the refrigerant flow's direction for cooling and defrosting the outside coil in the winter.

How can you choose the best Air Source heat pump?

Every home heat pump sold in the United States comes with an EnergyGuide label, which compares the heat pump's heating and cooling efficiency to that of other brands and models. The heating season performance factor (HSPF) for air-source electric heat pumps is a measure of the total heat delivered to the conditioned area, expressed in Btu, divided by the total electrical energy consumed by the heat pump system, expressed in watt-hours, over an average heating season.

Low airflow, leaky ducts, and wrong refrigerant charge are among issues that heat pumps might have. For each tonne of heat pump air-conditioning capacity, airflow should be between 400 and 500 cubic feet per minute (cfm). 


When airflow is less than 350 cfm per tonne, efficiency and performance suffer. If you want to know more about the air source heat pumps before installing one at your home, do connect with Harveys.
