The commercial gas boilers at Montem Primary School were also installed approximately 20 years ago and are at the end of their usable life. Annual servicing and maintenance has highlighted obsolete serviceable parts which means that future boiler maintenance tasks will be expensive and/or involve prolonged boiler plant down-time.
