How a Heat Pump Works: From Air to Comfort

A heat pump moves heat instead of generating it, making it energy-efficient for both heating and cooling. Here’s the process in simple steps:

 Heat Absorption

In heating mode, the heat pump absorbs heat from outside air, even in cold weather, using a refrigerant coil system.

 Heat Transfer

The refrigerant circulates, carrying the absorbed heat indoors through compression, raising its temperature efficiently.

 Indoor Heating

Warm air is released into your home via an indoor coil and fan system, keeping your space cozy and comfortable.

 Cooling Mode

In summer, the cycle reverses: heat is absorbed from indoors and expelled outside, cooling your living spaces.

What Is a Heat Pump?

A heat pump is a device that moves heat from one place to another using a small amount of electricity. Instead of generating heat by burning fuel, it absorbs heat from sources like the outside air. This process, known as heat transfer, allows the heating system to operate with higher energy efficiency compared to a traditional boiler. The captured heat energy is then used to heat your home and provide hot water, making it an environmentally friendly option.

How Heat Pumps Work in the UK Climate

Even during the winter, there’s enough heat from the outside air to warm your property. Air source heat pumps work by drawing in outdoor air, passing it over refrigerant-filled coils in the outdoor unit, and compressing it to raise the temperature. This warmed fluid is circulated through your central heating system or underfloor heating network, distributing comfort evenly. The process requires electricity, but it’s far more efficient than electric resistance heating, helping reduce energy bills while ensuring consistent warmth and domestic hot water supply.

Heat Pump Cycle — Visual Guide (Step-by-Step)

Clear, icon-led steps showing how an air source heat pump moves heat from outside to inside — perfect for quick consumer education.

Step 1 — Capture Outdoor Heat

Outdoor fan draws air across the evaporator coil; refrigerant captures low-temperature heat and becomes a warm vapor.

Step 2 — Compression Raises Temp

Compressor squeezes refrigerant, elevating its temperature to a level suitable for heating indoor air or water.

 

Step 3 — Deliver Heat Indoors

The heated refrigerant passes through the indoor coil; blower transfers heat to ducts or radiators, warming rooms efficiently.

Step 4 — Cycle Continues

Refrigerant expands, cools, and returns to the outdoor unit to absorb more heat — continuous, efficient operation.

Efficient — lowers bills
Reversible — also cools

The Technology Behind the System

The principle of Air Source Heat Pump Heating is simple yet highly efficient. The air-to-water heat pump takes heat from the air outside and upgrades it to a usable temperature indoors. Even in cold weather, the system extracts heat and transfers it to water, which flows through radiators or underfloor heating. The refrigerant in the heat pump and the compressor are key components, ensuring the system operates reliably. This process helps lower running costs and makes the technology suitable for year-round heating and cooling.

Components and Heat Transfer Process

A standard air source heat pump system includes an outdoor unit, a water tank, and a distribution system for heating and hot water. The heat pump transfers warmth through a refrigerant cycle, where energy is extracted from the air outside. This process is reversed in summer to provide cooling. The amount of heat delivered depends on the heat pump capacity, seasonal performance, and property insulation. When properly sized and installed, these systems meet the heating load efficiently and reduce dependence on a gas boiler.

Getting the Air Source Heat Pump Right

Sizing and Efficiency Considerations

To get the air source heat pump right, it’s essential to match the heat pump capacity with your home’s needs. Oversizing wastes energy, while undersizing requires auxiliary heating. Efficiency indicators like the seasonal energy efficiency ratio help you choose the best option. The minimum efficiency required ensures your heating system delivers value over its lifetime. Considering your heating mode, insulation levels, and the system you’re replacing is vital for achieving low running costs and optimal comfort throughout the heat pump’s life.

Hot Water from Your Heat Pump

How an air-source heat pump produces hot water efficiently — a circular, step-by-step visual that explains the process clearly.

Air Heat Capture

Outdoor air heat is absorbed into the refrigerant at the evaporator coil — the cycle begins.

Compression Boost

Compressor raises refrigerant temperature — converting low-grade heat to higher-temperature energy.

Heat Transfer to Water

Hot refrigerant passes through a heat exchanger, releasing heat into water stored in the cylinder or tank.

Stored Hot Water

Heated water is stored in an insulated cylinder ready for use — showers, taps, or radiators receive warm water.

Cycle Repeats

After heat release, refrigerant cools, expands, and returns to absorb more outdoor heat — continuous and efficient.

Air heat → Refrigerant

Compression & transfer

Heat exchanger → water

Tip:
Use a correctly sized heat pump and insulated tank for best hot-water performance.

Heating and Storing Domestic Hot Water

An air-to-water system can efficiently heat water for household use, storing it in a hot water tank. This ensures you always have enough domestic hot water for showers, baths, and kitchens. The heated water can be stored in a hot water tank for later use, reducing strain on the system during peak demand. This process also makes it easy to integrate radiators or underfloor heating, creating a combined heating and hot water solution that improves convenience and reduces energy use compared to separate appliances.

Combining Heating and Hot Water Systems

With Air Source Heat Pump Heating, you can heat your home and provide hot water using a single appliance. The system draws energy from the outside air and transfers it into water for both space heating and domestic needs. This combination improves efficiency and lowers running costs by maximising the captured heat energy. It’s also compatible with modern water heaters, and with the right design, it can integrate with your existing central heating system for improved comfort and cost savings.
