The vision of the Centre was to be an internationally significant cultural landmark and a centre for the performing arts, renowned for inspiration, excellence and leadership.

The Centre is today one of the most unique and lively performing arts centres in Europe, attracting some 1.5 million visitors every year, making it Wales’ No 1 visitor attraction. The building’s architecturally acclaimed interiors and exterior are featured in popular BBC television shows, such as Gavin and Stacey, Torchwood and Dr Who. It is recognised as an example of best practice in many areas, including its energy saving policies and environmental practices, and was the first independent theatre in the UK to achieve ISO14001.

Wales Millennium Centre has vast areas of public space to be heated but the requirement for heating also extends backstage for rehearsal rooms, dressing rooms, showers, kitchens and offices for the Centre’s staff and its eight resident companies.

Almost 5000kW of power are delivered by seven Hoval boilers, comprising two UltraGas 200, two AtmoGas and three SR-plus 1500 boilers. The boilers are housed separately and are serviced regularly by Hoval engineers to ensure optimal efficiency.

The two UltraGas 200 and two AtmoGas boilers look after the heating requirements of two resident organisations. They are economical on heating and power because of their large water capacity. The three SR-plus boilers operate up to 92% efficiency levels and provide the heat requirements for the main auditorium.
