May 2015 saw Warmer commence of a year-long heating installation project with Flintshire County Council. The project would see the installation of new communal heating system in two high rise buildings, including replacement of communal pipework and pipework to individual flats, valves, pumps, radiators. Creation of 4 heating zones. New controls installation. Variable speed pumps. TRV’s. Bollingbroke (101 flats 17 stories) and Richard Heights (81 flats 14 stories), were built in the 1960’s.
The 2 buildings were poorly insulated and were heated by an old and efficient communal boiler system. The heating system had poor control and no way of monitoring individual energy usage. Pressure issues and the inherent condition of the pipework was leading to regular leaks at the site, as often as three in a single week and residents were extremely unhappy at the disruption with loss of heating and hot water. The main boiler was located on the roof of Bollingbroke, which dropped down and fed heating in both blocks and high pressure was causing radiators to pop and putting pressure on pipework. We designed a system that split this single feed into 4 smaller plant rooms in each block, replacing all pipework on a floor by floor basis. We were able to isolate individual flats so disruption and downtime was minimised and we did not encounter delays to programme due to access issues to individual properties.
The blocks were getting a complete makeover with a Principle Contractor appointed to deliver concrete repairs, external wall insulation and roof insulation to increase the longevity and improve the energy efficiency of the buildings. At Warmer we worked closely with the Principal Contractor to programme and co-ordinate the heating upgrade of the building to minimise disruption and ensure a smooth programme of works, working closely with their TLO to develop robust communication activities to keep tenants informed of our activities, maximise access and customer satisfaction. For example as external works were being completed from top to bottom we commenced pipework from the basement up on a floor by floor basis to minimise cross over of workforce. We held daily, weekly and monthly operational meetings with the Principle Contractor and our full time TLO/Site Manager attended all resident consultation events. Due to the concrete construction of the building we also required the services of a specialist drilling subcontractor that was managed by us here at Warmer.
We minimised the need for system downtime through intelligent scheduling of works and the installation of a 500kw temporary boiler. We ensured minimal disruption, only having a maximum of 1.5 hours downtime for system changeovers on a floor by floor basis, where residents were consulted and fully informed, only undertaking changeovers at set times agreed with residents (between 11am and 1pm when demand was less).
Works were completed in July 2016. A massive well done to everyone involved with the project, another huge success for Warmer Energy Services.
