Sustainable heating & cooling

Heat pumps are versatile devices that can both heat and cool your home by transferring heat energy between indoor and outdoor environments. Using a refrigeration cycle, they extract heat from the air, ground, or water and transfer it to where it’s needed. There are several types of heat pumps, including air-source, ground-source, and water-source models, each with unique features and applications suited to different climates and building types.

The efficiency of heat pumps is typically measured by their Coefficient of Performance (COP) for heating. A higher COP indicates better performance, meaning the system uses less electricity to provide the desired heating or cooling output, improving sustainability. Heat pumps are an environmentally friendly option, as they significantly reduce carbon emissions compared to traditional fossil fuel-based systems and help combat climate change. They can also integrate with renewable energy sources like solar panels to further enhance sustainability and improve energy efficiency. Additionally, heat pumps offer long-term savings by lowering energy bills, reducing reliance on fossil fuels, and providing consistent indoor comfort throughout the year in all seasons.

What type of heat pump installation is right for you?

Heat pumps offer a versatile and energy-efficient way to heat and cool your property. With various types available, you can find a solution that perfectly matches your needs and helps reduce your carbon footprint and energy bills. Discover the different heat pump installation options we provide and learn how they can transform your home or business comfort.

Air-Source Heat Pumps (ASHP)

  1. Types and Functionality:
    Air-source heat pumps are the most common type, transferring heat between indoor and outdoor air. They come in two main subtypes:

    • Air-to-air: Regulates indoor temperature year-round.
    • Air-to-water: Provides heating through systems like radiators and also supplies hot water.
  2. Efficiency Across Climates:
    These systems are effective in various climates, making them suitable for both residential and commercial use.
  3. Performance and Benefits:
    Their efficiency is measured by the Coefficient of Performance (COP), typically ranging from 2.5 to 4.0. Proper installation and maintenance enhance performance, leading to cost savings and environmental benefits.

 

While the equipment shown here features the Vaillant aroTHERM plus 12kW air-to-water heat pump as an example, we also supply and install systems from other leading manufacturers, including Mitsubishi, to ensure the best fit for your specific needs.

Ground-Source Heat Pumps (GSHP)

Also known as geothermal heat pumps, these systems use the stable temperature of the ground to transfer heat efficiently. They require underground loops filled with a water-antifreeze solution, allowing consistent operation regardless of outdoor conditions. GSHPs are highly efficient but can be costly due to the complexity of the ground loop system.

There are two types of ground loops in GSHPs. Vertical loop systems suit properties with limited land, as loops are drilled deep into the ground. Horizontal loop systems require more space, as loops are laid in shallow trenches, making them cost-effective for rural areas.

GSHPs outperform air-source heat pumps. Their Coefficient of Performance (COP) ranges from 3.0 to 5.0, benefiting from stable underground temperatures. Their efficiency ensures excellent cooling performance. Beyond heating and cooling, GSHPs lower carbon emissions and reduce fossil fuel reliance, making them a sustainable investment.

Water-Source Heat Pumps (WSHP)

  1. Efficient Heat Exchange Using Water Sources:
    Water-source heat pumps utilize nearby water bodies (like ponds, lakes, or wells) to exchange heat efficiently, benefiting from stable water temperatures for consistent year-round performance.
  2. Two System Configurations:
    • Closed loop: Uses submerged, sealed pipes with antifreeze, minimizing water usage.
    • Open loop: Draws and returns water directly, offering high efficiency but requiring careful environmental management.
  3. High Efficiency and Sustainability:
    With a Coefficient of Performance (COP) between 3.0 and 5.0, these systems rival ground-source heat pumps in efficiency and support sustainability by reducing fossil fuel use and carbon emissions.
