The theatre is now 100 years old and is very expensive to heat due to a lack of insulation and air tightness. In the winter when it is particularly cold, audience numbers are reduced as a result.
Mineral wool insulation has been installed at a depth of 300mm above the main theatre and a new heating system is to be installed. The current system comprises of a gas fired system that extracts ambient cold air and blows warm air into the theatre space via un-insulated ductworks. This system is highly inefficient and is to be replaced by a highly efficient condensing gas fired boiler which will produce hot water and transfer warm air through fan coils.
Based on EiEs calculations installing loft insulation will reduce the heating requirements of the main theatre by approximately 33% and according to the Energy Rating Services (ERS) the new heating system will reduce overall energy use (before insulation) by 24%. The combination of these improvements will result in savings of approximately £570/yr.
Importantly the new heating system will also provide a greater level of comfort and should help the theatre attract greater audiences in the winter months.
