Built in 1494 during the reign of Henry VII, the historic Square Tower in Portsmouth has undergone many changes of use during its 524-year life. Following a major refurbishment, including a new heating system, the tower, owned by Portsmouth Council, has become a popular venue for weddings and corporate gatherings.

During the refurbishment Dunham-Bush worked closely with the council, who undertook the design of the heating system. Work had to comply with English Heritage requirements and consideration had to be given to protecting the tower’s structure without damage or alteration to its appearance.

An appropriate aesthetic integration of the heat emitters was also an important criterion for product selection. The new system had to be functional, unobtrusive and quiet, delivering an even distribution of efficient heating around the building.

Dunham-Bush Hydrocourse trench heating provided the ideal solution. The system includes 63 metres of bespoke HTA-2s trench heating, with heavy duty I-bar grilles for extended life. Finished in powder coat Vandyke brown, the alloy floor grilles ensured continuity of appearance with the previous floor duct cover boards. As a precaution against the damp conditions along the south wall, the steel trench boxes were zinc-coated prior to stove powder coating.

The installation was carried out by Concept Building Services (Southern) Ltd, and project managed by SSE Contracting Ltd, Portsmouth.

This historic building is leased by the council to proprietor Steve Hender, who, commenting on the work and the future for the Tower, said: “The new heating system is fantastic; it means that for the first time we can guarantee to our customers that the building is warm. And not only is the system highly efficient, it has been installed in a manner that is most sympathetic to the historical nature of the building.”
