The Northolt Leisure Centre project, led by Megan Renewable Installations (MRI), is a forward-thinking decarbonisation initiative designed to significantly reduce carbon emissions and enhance energy efficiency.
As part of this transformative effort, half of the existing gas boilers have been removed and replaced with a powerful 650 kW Air Source Heat Pump (ASHP) to charge the low-temperature heating circuit. To further optimise efficiency, the existing 260 kW air-cooled VRF units were upgraded to water-cooled VRF units, allowing waste heat generated during cooling mode to be recovered and injected back into the low-temperature circuit. Complementing this system, a solar thermal array of 330 tubes has been installed on the roof, generating approximately 120 kW of heat directly from solar energy.
On the high-temperature circuit, MRI has introduced two Water-to-Water Heat Pumps (WWHPs) with a combined capacity of 900 kW. These WWHPs efficiently raise water temperature to 80°C, providing a sustainable alternative to the removed gas boilers. Once fully operational, the heat pump system will eliminate gas consumption entirely, with electricity becoming the primary energy source. While electricity usage will increase, the overall design is projected to reduce CO₂ emissions by approximately 370 tonnes annually.
This innovative project not only modernises Northolt Leisure Centre’s energy infrastructure but also demonstrates MRI’s unwavering commitment to delivering sustainable, low-carbon energy solutions for a cleaner, greener future.
