This gas heating system in a 1960s Leicestershire bungalow could be original to the property: around fifty years old and still apparently working! The bungalow is tenanted and the system had passed it’s annual safety check recently.
However, there are clear questions about its efficiency and longer term effectiveness. The advice on such an old system will be to replace it pretty much immediately. Care will be needed with the boiler flue: it is formed of asbestos cement which is a potentially hazardous material.
