United Kingdom-Wrexham: Commissioning of heating installations

'Redwither Tower is an office building owned by Wrexham County Borough Council (WCBC) which provides commercial office space to a number of businesses in Wrexham. Redwither Tower is located within Wrexham Industrial Estate, it is a 4-storey building which has a current occupancy of approximately 50 % although WCBC plan to increase occupancy to 100 % over the next few years. The total heated floor area of the building is 17 000 m. Space heating is currently supplied throughout the building by 3 x 1.2MW gas boilers. Domestic hot water throughout the building is supplied by local point of use electric water heaters. The gas boilers and all plant equipment are housed in a plant room on the ground floor. WCBC wish to remove the existing gas boilers and install a circa 750 kW wood pellet boiler to serve the space heat demand of the building, in order to reduce carbon emissions at the site and to benefit from the Renewable Heat Incentive. DHW will continue to be supplied by the existing electric point of use water heaters which will be retained in place. The new biomass boiler system will be located within the existing ground floor plant room. 2 new circa 1.2-1.5MW gas boilers will also be installed within the plant room following removal of the existing gas boilers. The new gas boilers will provide auxiliary heating. Heat will be distributed around the building via the existing heat distribution network which includes 12 local plant rooms (four local plant rooms on each of the 1st, 2nd and 3rd floors). The scope of work involves the supply and mechanical and electrical installation of the biomass boiler with fuel feed system, thermal stores, flue and all ancillary equipment inside the existing plant room. The works also include the removal of the three gas boilers and all associated pipe work and equipment from the existing plant room and the installation of 2 new gas boilers and flues for auxiliary heat. The works also include the supply and installation of an external wood fuel store including all foundations and penetrations for fuel augers.
