Dodd Group was engaged by Kier to install the MEP services at Ysgol Y Graig, a new build two storey primary School with Early Years facility situated in Cefn Coed, Merthyr Tydfil.
Primary LTHW services are generated by a two number gas fired condensing boiler cascade arrangement in a centrally located Plantroom. Secondary ground and first floor variable temperature systems serve an underfloor heating system, radiators and Hybrid ventilation units, the constant temperature system serves a Kitchen AHU and ceiling tile heaters.
