What Are Air Source Heat Pumps and How Do They Work?
A guide to one of Ireland’s fastest-growing heating and cooling technologies.
According to SEAI, heat pumps can reduce heating energy usage by up to 60% compared to oil boilers.
What Is an Air Source Heat Pump?
Air source heat pumps (ASHPs) extract heat from the outside air and transfer it indoors using a refrigeration cycle. This energy-efficient technology can provide both heating and cooling, even when outdoor temperatures drop. By compressing and expanding refrigerant, the system pulls heat from the environment and distributes it inside through radiators, underfloor heating, or air units.
ASHPs are seen as a cornerstone of Ireland’s move toward low-carbon homes and businesses. They’re quieter, cleaner, and more sustainable than traditional boilers. Two common types are air-to-water and air-to-air systems.
If you’re already exploring energy-efficient ventilation systems for your project, integrating a heat pump could take your building’s performance to the next level.
Benefits of Air Source Heat Pumps for Irish Properties
These systems dramatically reduce energy bills over time thanks to their high efficiency. They’re ideal for both retrofits and new builds — especially when paired with underfloor heating or low-temperature radiators.
Grants and incentives from SEAI make them even more attractive for homeowners and businesses looking to decarbonise. ASHPs also require less maintenance than gas or oil boilers, and they significantly reduce carbon emissions.
If you’re planning a system upgrade, custom ventilation solutions that include ASHP integration are worth considering.
Is an Air Source Heat Pump Right for You?
ASHPs are a long-term investment. Upfront costs are higher, but the long-term savings — especially in commercial or multi-unit buildings — can be substantial. They work best in well-insulated spaces and are perfect for clients focused on sustainability.
Before making a decision, it’s best to speak with a team that specialises in ventilation installation services to assess your property’s suitability and layout. A proper site assessment will look at your building’s insulation levels, space planning, and existing heating systems.
