Case studies

Upton House listed building uses Hamworthy commercial boilers

Upton House

Sector: Listed building refurbishment

Project: Grade II* listed building Upton House in Poole was in need of a boiler plant refurbishment. Thanks to Hamworthy looking for a test site and a close co-operation between council and manufacturer, a space-saving Upton boiler was installed. This improved the heating control to different floors of the building.

Building: Listed building plant room refurbishment

Application: Space heating 394kW
