This vehicle engineering company was looking at ways to reduce the running costs of heating their workshop.
Global Energy Systems determined we could heat this size of a workshop with three 18kW, three phase Winchester heat pumps which provide heat via 4 x fan units. The estimated annual savings against previous running costs is £6,086 and this installation is eligible for the domestic RHI incentive which will receive payments for 20 years.
The owner of this large Grade II listed country house approached Global Energy Systems following a recommendation, seeking to reduce the high running costs associated with a fully oil-based heating system.
After a detailed site assessment and system design in line with MCS standards, Global Energy Systems installed three Caernarfon air source heat pumps, integrated with the existing oil boiler to create a bi-valent (hybrid) heating system.
This setup allows the heat pumps to operate as the primary, low-carbon heat source, significantly reducing reliance on oil, while the existing boiler provides additional support during periods of high demand or extreme weather.
The installation is expected to deliver annual savings of £7,139, including income from the non-domestic Renewable Heat Incentive (RHI), which provides payments over a 20-year period.
This project demonstrates how renewable heating solutions can be successfully integrated into heritage properties, improving efficiency and reducing costs while preserving the character of the building.
During the renovation and extension of this converted chapel, the owners explored renewable energy options to improve efficiency and reduce long-term running costs.
Global Energy Systems designed and installed an 18kW Caernarfon air source heat pump to meet the full heating and domestic hot water demand of the property.
The system delivers reliable, low-carbon performance and is expected to achieve annual savings of £2,286 compared to oil heating. This figure includes income from the Domestic Renewable Heat Incentive (RHI), for which the installation was eligible.
This project demonstrates how air source heat pumps can be effectively integrated into unique residential conversions, providing a sustainable and cost-effective alternative to traditional heating systems.
The homeowners of this detached five-bedroom property were experiencing ongoing issues with an existing air source heat pump installed by another manufacturer, particularly around system performance and controls.
Following a recommendation, Global Energy Systems carried out a full assessment and upgraded the system by installing an 18kW Caernarfon air source heat pump, integrated with the existing gas boiler to create a hybrid (bi-valent) heating system.
The new system provides heating via underfloor heating and supplies full domestic hot water, delivering improved reliability, efficiency, and control.
Since installation, the homeowners have been accepted onto the Domestic Renewable Heat Incentive (RHI) and have reported a significant improvement in system performance and overall satisfaction. The upgrade is expected to deliver annual savings of £2,363 compared to previous running costs.
This project highlights the importance of correct system design and control, as well as the benefits of upgrading to a reliable and well-supported heating solution.
The owner of this scenic riverside property was experiencing poor performance from an undersized ground source heat pump installed by another provider, which was unable to adequately heat the home.
Global Energy Systems carried out a full assessment and installed an 18kW Caernarfon air source heat pump, designed to meet the property’s full heating and domestic hot water requirements. The system provides heat via underfloor heating and radiators, ensuring consistent comfort throughout the home.
Since installation in August 2018, the homeowner has experienced a significant improvement in performance and reliability. The system is expected to deliver annual savings of £2,134 compared to previous running costs, including income from the Domestic Renewable Heat Incentive (RHI), for which the installation is accredited.
This project demonstrates how correctly specified air source heat pump systems can effectively resolve performance issues and deliver both efficiency and long-term cost savings.
