What does a heat pump do?

Heat pumps are becoming a cornerstone of sustainable living, yet many people are still unfamiliar with their function and benefits. To put it simply, a heat pump transfers heat from one area to another using a highly efficient process. Unlike conventional boilers or air conditioners that consume energy to generate heat or cool air, heat pumps work by moving heat, making them significantly more energy-efficient.

The Process: How Heat Pumps Work

Heat pumps operate using a refrigeration cycle, which involves a series of thermodynamic processes. The cycle begins by absorbing heat from a source, which can be the air, ground, or water, depending on the system type. This heat is then compressed, which increases its temperature, before being transferred into your home or building. In cooling mode, the process reverses, removing heat from your space and releasing it outside. Understanding the components of a heat pump is crucial to appreciating how this innovative system operates. Each part plays a specific role in the heat transfer process, ensuring the system delivers efficient heating and cooling.

The key components of a heat pump system include:

  • Evaporator Coil

The evaporator coil is responsible for absorbing heat from the external environment, whether it’s air, ground, or water. As the refrigerant passes through the coil, it changes from a liquid to a gas as it captures heat. This step is the starting point of the heat pump’s energy-efficient operation.

  • Compressor

The compressor plays a vital role by pressurising the refrigerant, which significantly raises its temperature. Located in the outdoor unit, the compressor is the powerhouse of the system, ensuring the refrigerant is at the right pressure to transfer heat effectively. Without the compressor, the heat pump wouldn’t be able to operate efficiently.

  • Condenser Coil

After the refrigerant is heated by the compressor, it moves to the condenser coil. Here, the refrigerant releases the absorbed heat into your indoor environment, warming your home or building. This process ensures consistent heating, even in cold weather conditions, by maximising the heat exchange efficiency.

  • Expansion Valve

The expansion valve reduces the pressure and temperature of the refrigerant, allowing it to revert to a liquid state. This process prepares the refrigerant for the next cycle, ensuring the heat pump can continuously operate. It acts as the reset button, ensuring the system can start the process anew without energy wastage.

This seamless transfer of heat makes heat pumps highly efficient and versatile, providing not only heating and cooling but also hot water in many systems. The ability to perform multiple functions with minimal energy usage is what sets heat pumps apart from traditional heating and cooling systems.

Different Types of Heat Pumps

Heat pumps come in various types, each designed to suit specific environments and energy needs. Their functionality is determined by the source from which they extract heat.

  • Air Source Heat Pumps (ASHPs)

These are the most widely used type of heat pump due to their versatility and cost-effectiveness. They extract heat from the air, even in temperatures as low as -15°C, making them ideal for the UK climate. With advancements in technology, modern ASHPs can operate efficiently in colder weather, providing reliable year-round performance.

  • Ground Source Heat Pumps (GSHPs)

Also called geothermal systems, these pumps extract heat stored beneath the Earth’s surface. Since ground temperatures remain relatively constant throughout the year, GSHPs offer stable and efficient heating and cooling. While the installation involves more upfront effort, such as burying loops underground, the long-term benefits in energy savings and performance make them a worthwhile investment.

  • Water Source Heat Pumps

These systems harness thermal energy from nearby water sources, such as lakes, rivers, or wells. They are particularly effective in areas with accessible water bodies, offering high efficiency due to the stable temperatures of water. Water source heat pumps are often used in specific commercial or industrial settings but can also suit certain residential applications with proper planning.

At Chillmech, we cater to both commercial and domestic heat pump needs to ensure that all clients benefit from this innovative technology:

  • Commercial Heat Pumps

These systems are tailored for high-demand environments such as office complexes, schools, and industrial facilities. Designed for robustness and scalability, commercial heat pumps deliver exceptional energy efficiency while integrating seamlessly with existing HVAC systems.

  • Domestic Heat Pumps

Perfect for homeowners seeking an eco-friendly alternative to traditional heating systems, domestic heat pumps offer unmatched efficiency and versatility. They can be paired with underfloor heating, modern radiators, or ducted systems to enhance comfort and energy savings. Many homeowners also appreciate their compact design and quiet operation, which seamlessly fit into residential settings.

Our expert consultation and tailored approach make the transition to heat pumps smooth and rewarding. Contact us today for your FREE survey – we can’t wait to hear from you!

The Benefits of Heat Pumps

  • Exceptional Energy Efficiency

One of the most notable benefits of heat pumps is their unmatched energy efficiency. Traditional heating systems, like boilers, typically have an efficiency rating of around 90%. Heat pumps, on the other hand, can achieve efficiencies of up to 400%, meaning they produce four times as much energy as they consume. This efficiency stems from their ability to move heat rather than generate it, resulting in lower energy usage.

  • Cost Savings Over Time

While heat pumps may have a higher upfront cost compared to traditional systems, their operational efficiency leads to significant savings on energy bills. Many property owners recoup their investment within a few years, making heat pumps a cost-effective long-term solution. Furthermore, the reduced reliance on fossil fuels shields homeowners from the volatility of energy prices, providing financial stability over time.

  • Environmentally Friendly

Heat pumps play a pivotal role in reducing carbon footprints. By utilising renewable energy sources like air, ground, or water, they minimise greenhouse gas emissions. Additionally, they align with the U.K. government’s push for renewable energy adoption and the phase-out of gas boilers by 2035. Choosing a heat pump contributes directly to achieving climate goals while enhancing energy efficiency at a personal level.

  • Dual Functionality – Heating & Cooling

Unlike most conventional systems, heat pumps are versatile. They offer both heating in winter and cooling in summer, eliminating the need for separate devices. This dual functionality saves space and simplifies your HVAC system, making it a practical and economical choice for properties of all sizes.

  • Low Maintenance Requirements

Heat pumps are designed for durability and require minimal maintenance. Annual servicing to check components like the refrigerant levels, filters, and coils is usually sufficient to keep them running efficiently. Their design focuses on reliability, which reduces the likelihood of unexpected breakdowns and additional repair costs.

  • Long Lifespan

A properly maintained heat pump can last 20–25 years, outlasting many traditional heating systems. This long lifespan reduces the need for frequent replacements, further enhancing their cost-effectiveness. Investing in a heat pump means you’ll benefit from consistent performance and lower running costs for decades.

  • Adaptability & Integration

Heat pumps can be easily integrated into existing heating systems or installed as standalone units. They are compatible with various technologies, including underfloor heating, radiators, and smart thermostats, giving you complete control over your comfort. This flexibility makes them suitable for both modern builds and retrofit projects, accommodating diverse property types.
