Commercial-Grade Air Source Performance With A Lighter Carbon Footprint.
At Yarrow Energy, we’re proud to help businesses and research organisations across Scotland transition to low-carbon heating systems that are both future-ready and cost-efficient. Our recent installation at the West of Scotland Science Park exemplifies how advanced air source heat pump technology can meet the heating demands of high-usage commercial environments — while significantly reducing carbon emissions.
This particular site required a scalable, reliable solution that could deliver strong performance all year round. After careful planning and specification, we installed three Mitsubishi CAHV commercial air source heat pumps — a robust system designed for commercial heating applications where consistency, efficiency, and sustainability are non-negotiable.
Why Mitsubishi CAHV?
We selected the Mitsubishi CAHV series for this project based on a combination of factors: proven performance in UK climates, high seasonal efficiency ratings, and the ability to cascade multiple units for greater output. These commercial-grade units are built specifically for high-demand environments, and are well-suited to properties with larger heat loads and complex heating schedules.
Each CAHV unit has the flexibility to operate independently or as part of a modular system, making them ideal for future expansion or phased development across the site. The client was looking for reliability and long-term resilience, and the Mitsubishi platform delivered on both counts.
Project Scope And Execution
The installation involved the careful siting and commissioning of three CAHV air source heat pumps, configured to work in tandem. Our engineers managed the full design and integration process, ensuring the system could interface with the site's internal heating network and deliver consistent output across the designated zones.
The units were installed in an external plant area, with consideration given to airflow clearance, acoustic requirements, and ease of future servicing. Internally, the heat pumps were linked to a buffer tank and distribution system, allowing for intelligent load balancing based on building demand.
Despite the scale of the install, the project was delivered with minimal disruption to the park’s operations. We worked closely with on-site facility managers to ensure that all health and safety standards were met, and that the system was brought online in accordance with Mitsubishi’s best practice commissioning standards.
Carbon Reduction And Energy Efficiency
Switching to commercial air source heat pumps represents a significant step forward in reducing the environmental impact of heating large buildings. Compared to legacy systems powered by gas or oil, the new system at the Science Park offers substantial reductions in CO₂ emissions — without compromising on comfort or control.
Because the CAHV units deliver heat using ambient air as a renewable source, the energy input is far lower than with conventional heating. Combined with proper system design and zoning, this has translated into marked improvements in both energy use and long-term cost efficiency for the client.
The Science Park installation is also a strong example of how commercial buildings can take action ahead of incoming energy regulations and net-zero targets — using proven, scalable technologies available today.
Building Toward A Greener Future
At Yarrow Energy, we believe that sustainable technology must also be practical and performance-driven. That belief shaped every element of this project — from system design and product selection to installation and aftercare.
This installation stands as another milestone in our growing portfolio of commercial renewables. It showcases what’s possible when innovation meets precision, and when businesses make the proactive choice to reduce their carbon footprint while investing in smarter infrastructure.
We’re proud to be playing our part in shaping a cleaner energy future for Scotland’s business and research sectors — and we’re ready to bring the same expertise to your next project, whether it’s a single building or a whole portfolio.
