Wadhurst Castle in East Sussex is a listed Victorian residence which had a very old and poorly controlled heating system fed by an obsolete boiler. The heating system around the building was mostly retained but connected to a new distribution system in the basement with several individually controllable heating zones. The existing boiler was replaced by a modern condensing boiler with weather compensating controls. The heating modifications were completed in 2016.
A new wing is currently being constructed containing a ballroom, which will allow the castle to be used as a wedding venue. The new ballroom is mechanically ventilated and air-conditioned. The ventilation system uses acoustic treatment to reduce the impact on neighbouring properties of loud music in the ballroom. The new ventilation plant uses heat recovery and heat pump heating and cooling and it is located in a basement plantroom below the dance floor. In addition to the ballroom additional kitchen, toilets and storage areas are to be constructed in the basement of the castle. The ballroom project should be completed during 2017.
