Two highly-efficient 120kW Trigon L boilers have been installed at a historic naval dockyard church in Chatham as part of a new central heating system that is expected to reduce gas usage by more than 20%.

The former Pembroke Barracks naval church is a listed building completed in 1906 and is now known as the St. George’s Centre. Owned by Medway Council, it houses 94 stained glass windows as well as memorial plaques to the fallen of both world wars.

Medway Council needed to replace the centre’s ageing cast iron atmospheric boilers with an efficient condensing model while maintaining the existing pipework. Therefore the crucial factor in the selection of Trigon L condensing boilers for the centre was the option of a built-in plate heat exchanger to separate the boiler from the primary heating circuit.

John Richardson of Medway Council’s Design and Surveying Team, who specified the boilers, commented: “Trigon L boilers suited our requirements at the centre – having a very old heating system and large pipework with the possibility of accumulated debris. It made sense to divorce the system water from the boiler by means of the heat exchanger.”
