The Chelsea Old Town Hall (COTH) Decarbonisation Project, led by Megan Renewable Installations (MRI), is a groundbreaking initiative aimed at replacing traditional gas boilers with a sustainable, energy-efficient heating and cooling system.
MRI is deploying advanced 4-pipe air source heat pumps (ASHPs) that not only provide efficient heating and cooling but also recover and repurpose heat for optimal energy use. These ASHPs, with a combined heating capacity of 650 kW and a cooling capacity of 430 kW, harness heat generated during cooling to warm the building’s pool and other areas.
To maximize efficiency, the ASHPs heat water to 45°C, supplying the pool, heating air handling units (AHUs), and acting as the primary heat source for three water-to-water heat pumps (WWHPs). The WWHPs further elevate the water temperature to approximately 80°C, creating a high-temperature circuit suitable for domestic hot water cylinders and the existing high-temperature heating systems throughout the facility.
This innovative design not only reduces reliance on fossil fuels but also significantly cuts carbon emissions. By transitioning to this advanced heat pump system, MRI anticipates a reduction of at least 170 tonnes of CO₂ annually, making a substantial contribution to the decarbonisation of Chelsea Old Town Hall while promoting long-term sustainability and energy efficiency.
