The Cadogan family has maintained a property portfolio in London’s Chelsea for over 300 years. The Estate presides over a glittering collection of important period architecture which includes the Holy Trinity Church, just off Sloane Square.
Maintenance revealed that the existing heating system was not only inadequate for the lofty interior of the church but was also dehydrating the structure’s timber. This was of particular concern to the engineers due to replace the church organ.
Gratte Brothers was commissioned to conduct a feasibility study into a replacement system, and so a full 3D survey of the building was conducted.
Gratte Brothers proposed several solutions, explaining the advantages and disadvantages of each including; trench heating, infra-red, underfloor heating and refurbishment of the existing systems.
To ensure a temperate climate for the parishioners and the new organ, a computational fluid dynamics report was prepared for the chosen solution: new gas-fired air-handling units fitted with a noise-reducing membrane and humidification unit. Key to the solution would be to replace the existing grilles with motorised multi-directional units and increase the number. Using the fluid dynamics report, Gratte Brothers configured the grilles for best performance.
After providing this detailed study, Gratte Brothers was awarded the contract to fit the system. The installation was undertaken whilst the building was a functioning place of worship and was commissioned before winter took hold.
