This large country house in Scotland was previously reliant on oil heating, with annual costs reaching approximately £8,000. The owner sought to reduce running costs while minimising exposure to fluctuating oil prices, particularly during peak winter periods.

Global Energy Systems designed and installed a 45kW air source heat pump, integrated with the existing oil boiler to create a bi-valent (hybrid) heating system. This approach allows the heat pump to operate as the primary, low-carbon heat source, with the oil boiler providing additional support during periods of extreme demand or low temperatures.

The system is managed using Global Energy Systems’ proprietary control software, ensuring efficient operation, seamless switching between energy sources, and optimised performance throughout the year.

This solution delivers improved energy efficiency, reduced reliance on oil, and greater cost stability, making it ideally suited to large rural properties with high heating demands.

Designed to exacting architectural standards, this large and contemporary new-build property required a high-performance heating system that would avoid the long-term cost uncertainty associated with oil-fired heating.

Global Energy Systems installed a 23kW air source heat pump to provide both central heating and domestic hot water. The system serves a combination of underfloor heating and radiators, ensuring efficient and consistent comfort throughout the property.

The installation has delivered strong performance, with annual running costs of £2,552, representing an estimated saving of £2,300 compared to oil. In addition to the financial benefits, the homeowners have gained greater peace of mind, knowing they are protected from future fluctuations in oil prices.

This project highlights how air source heat pumps can complement modern architectural design, providing an efficient, reliable, and future-proof heating solution.

During the refurbishment of this 1895 property, the owner explored renewable energy options with the aim of reducing their carbon footprint, despite the property already having access to mains gas.

Global Energy Systems installed a 10kW Thurso air source heat pump, providing an efficient, low-carbon heating solution for the home. The system is designed to deliver reliable performance while significantly improving overall energy efficiency.

The owner is also considering the future addition of solar PV panels, which would allow the property to generate its own electricity and further reduce running costs by powering the heat pump with renewable energy.

The installation is expected to achieve annual savings of £1,647, demonstrating the financial and environmental benefits of transitioning to renewable heating, even in properties connected to the gas grid.

Global Energy Systems installed a 9kW air source heat pump to provide full heating and domestic hot water for two luxury accommodation lodges at Cartford Lodges.

The system was designed to deliver efficient, low-carbon heating while maintaining high levels of comfort expected in premium holiday accommodation. By utilising renewable technology, the lodges benefit from reduced energy consumption and improved sustainability.

The installation is expected to generate annual savings of £1,223, while also qualifying for the non-domestic Renewable Heat Incentive (RHI), providing government-backed payments over a 20-year period.

This project highlights how air source heat pumps can offer both environmental and financial benefits for high-end hospitality settings.

Global Energy Systems installed an 18kW Caernarfon air source heat pump to provide efficient heating for a garden centre, café, and gift shop.

The system delivers heat via underfloor heating, creating a comfortable and consistent indoor environment for customers and staff across the retail and hospitality spaces.

By switching to air source heat pump technology, the site benefits from improved energy efficiency and reduced operating costs, with annual savings of £2,226.

This installation demonstrates how renewable heating solutions can effectively support mixed-use commercial spaces while delivering both environmental and financial benefits.

Global Energy Systems delivered an efficient heating solution for the King George Hotel, a traditional Lake District inn, providing reliable warmth throughout both the public house and guest accommodation areas.

The system was designed to enhance comfort for guests and staff while improving overall energy efficiency and reducing running costs. By adopting renewable heating technology, the hotel benefits from a more sustainable approach to heating without compromising performance.

The installation is RHI accredited, generating additional financial returns and delivers annual savings of £4,924, highlighting the strong economic and environmental advantages of the upgrade.

When moving offices to a bigger space this client enquired about renewable energy. Global Energy sized two 18kW, three phase Winchester air Source heat pumps to heat their offices and provide hot water.

The annual savings are estimated to be £1,154 and are also eligible to apply to the non-domestic government grant which will receive payments for 20 years, and add an additional annual saving of £1,550.

Global Energy Systems installed three 18kW Caernarfon air source heat pumps at Amersham Hockey Club as part of a recent refurbishment project.

The system provides efficient, low-carbon heating and domestic hot water, ensuring a comfortable environment for players, staff, and visitors throughout the facility.

With a focus on improving energy efficiency and reducing operational costs, the installation is expected to deliver annual savings of £3,686, demonstrating the financial and environmental benefits of modern heat pump technology in sports and leisure facilities.

Douglas Borough Council has become the first local authority to use renewable energy technology – an air source heat pump (ASHP) – to heat its greenhouses.

The nursery’s oil heating system was coming to the end of its economically viable life and after careful analysis it became clear an air source heat pump would not only reduce the Council’s carbon footprint, but would also lead to savings on fuel oil, estimated to be in the region of £12,000 annually from April 2017. In addition to this, the electrical power for the pump attracts a reduced tariff so this new system is not only environmentally responsible and cost effective but will also, in the longer-term, help to lessen the impact on the rates.

Features of our ASHP include a remote monitoring facility to ensure that our heat pumps are monitored 24/7 and that they are built for 25 years reliability.

‘Douglas Borough Council is to be complimented on this installation that will not only reduce fossil fuel use but also carbon emissions to near zero, so the Council is not only reducing its carbon emissions but also saving money by reducing the spend on oil.’

The air source heat pump installed at Ballaughton Nurseries is probably the largest installation on the Island – and definitely the first horticultural application – and will make a substantial contribution to reducing the Isle of Man’s carbon emissions. It is forecast to deliver significant cost savings by removing the dependence on heating oil to keep the greenhouses and nursery plants warm during the cold winter months.’

During the renovation of two cottages, the owners chose to install a renewable heating solution to improve energy efficiency and reduce long-term running costs.

Global Energy Systems installed a 10kW Thurso air source heat pump in each property, providing independent, efficient heating for both cottages.

The systems deliver reliable, low-carbon performance, with estimated annual savings of £1,732 per cottage compared to previous heating costs.

This project highlights how air source heat pumps can provide a cost-effective and sustainable solution for residential renovation projects.
