Do Air Source Heat Pumps Use a Lot of Electricity?

As more homeowners in Glasgow look for sustainable heating solutions, air source heat pumps (ASHPs) have gained popularity. However, one common question is whether these systems use a lot of electricity. At HeatCo Scotland, we specialise in the installation and maintenance of air source heat pumps in Glasgow and throughout Scotland, and we’re here to provide you with the information you need.


Understanding Air Source Heat Pumps

Air source heat pumps work by extracting heat from the outside air and transferring it into your home. This process involves a few key components:

  1. Evaporator: The ASHP draws in outside air, which passes over a refrigerant in the evaporator coil. The refrigerant absorbs heat from the air and evaporates.
  2. Compressor: The evaporated refrigerant is compressed, which significantly increases its temperature.
  3. Condenser: The hot refrigerant passes through the condenser coil, releasing heat into your home’s heating system, such as radiators or underfloor heating.
  4. Expansion Valve: The refrigerant then passes through an expansion valve, cooling down and returning to its original state, ready to absorb more heat from the outside air.


Electricity Usage of Air Source Heat Pumps

Air source heat pumps do use electricity, but they are highly efficient. For every unit of electricity used, an ASHP can produce three to four units of heat, making them much more efficient than traditional electric heaters. The actual electricity consumption will depend on several factors:

  • Climate: In milder climates like Glasgow, ASHPs are particularly efficient as they don’t have to work as hard to extract heat from the air.
  • System Size: The size of the heat pump and your home’s insulation can affect electricity usage. A well-insulated home requires less energy to heat.
  • Usage Patterns: How often and how intensively you use your heating system also plays a role.


Benefits of Air Source Heat Pumps

  • Environmental Impact: ASHPs reduce your carbon footprint by using renewable energy from the air.
  • Cost Savings: Despite using electricity, the high efficiency of ASHPs can lead to lower energy bills compared to conventional heating systems.
  • Versatility: They provide both heating and cooling, making them a versatile choice for year-round comfort.
