These Sanyo carbon-dioxide heat pumps have been installed to replace LPG space heating in a former medieval priory that is now holiday accommodation.

Sanyo’s Eco carbon-dioxide heat pumps have been installed to provide space heating in a former medieval priory that is now holiday accommodation owned an managed by the Landmark Trust. The Grade 1 listed Woodspring Priory was previously heating by an LPG system, which was proving very expensive to run.

The new heating system for this former Augustinian priory beside the sea near Weston-super-Mare consists of three split-system heat pumps using carbon dioxide as the refrigerant. The system was installed by South West Heat Pumps and supplied by ICG.

The 27 kW installation is linked to radiators and a DHW store. Owing to the historic nature of the site, the installation was carried out under the guidance of an archaeologist to ensure that site sensitivities were respected.

This installation is part of a rolling programme of heat-pump installations in Landmark Trust buildings. This charity has over 180 historic buildings throughout the UK, many of which are in isolated and rural locations where energy availability, such as no mains gas, and cost are issues.

The Landmark Trust is carrying out a survey to identify its 20 most energy-hungry buildings. It will use the information to prioritise investing in heating replacement, with a significant contribution expected from heat-pump technology.
