Rule & Parker has for over thirty years carried out refurbishment to plant rooms, residential nursing homes, sheltered accommodation and light commercial properties. Rule & Parker has installed over ten new boiler plant rooms in sheltered accommodation for Aragon Housing Association.

An example of such work is the 2016 project - Orchard House, Harlington in Bedfordshire. A twenty five apartment sheltered residential home with communal meeting room facilities.  In this example, the old boiler plant was removed and replaced with three Broag Quinta wall mounted commercial boilers on a low loss header. The main heating system is a constant pressure variable volume system which is self-balancing according to the demands of the system. The system pressure is maintained via pressure differential switches acting on inverter controlled variable speed duty/standby heating Grundfos pump sets. Excess pressure on individual circuits is controlled via pressure regulating valves installed on the heat interface units (HIU) within the flats and on the sub-branches serving the communal radiator circuits. Each resident’s apartment has individual heating control via wall mounted room thermostats linked to the HIU. Each apartment is fitted with a local isolation switch to enable the heating system to be turned off by Property Manager when the apartment is unoccupied.

Key objectives:-

  • Complete the works with total respect for the residents homes.
  • Modernise existing heating & hot water system.
  • Reduced residents fuel bills through the use of highly energy efficient equipment.
  • Ensure services are available 24/7; have inbuilt redundancy should an element fail.
  • Ensure residents maintain individual control over their apartments heating & hot water needs.
  • Maintain current residents heating / hot water facilities whilst work is in progress.
  • Work in an efficient, health & safety lend environment.

Residents welfare - Health & Safety was paramount and following a detailed risk assessment a temporary fire alarm system was installed to work alongside the buildings main fire alarm, which was brought back into operation each evening after works were completed for the day. As part of the project existing lighting was upgraded with LED equipment and operated by passive  infra-red controls.
