160kW Ground-Source Heat Pump (GSHP) Installation Opportunity

7th February 2022 – 14th March 2022

Kingston Lacy House is a National Trust Grade 1 listed Mansion set in Grade 2 listed Historic Parkland and Gardens located on the outskirts of Wimborne. The Trust is seeking applications from experienced contractors to tender for the design, supply and installation of a 160kW mono-valent ground source heat pump system to replace the existing oil boilers and plant.

The contract is divided into four work packages (WP):

WP1 – Design

WP2 – Supply and Installation of GSHP

WP3 – Building Works (new plant room and substation)

WP4 – Monitoring and Modification of Mansion Heating System (post installation)

Planning permission and listed building consent has been granted for the project.

The system will consist of a collector array of 36 vertical boreholes between 150m – 200m deep connected to two high temp heat pumps capable of 60° output connected via a buffer tank to two existing low temp hot water circuits providing conservation heating and comfort heating to the Mansion.

Only contractors capable of managing all four work packages and with experience of comparable heat pump installations in historic buildings need apply.

Contractors must be Constructionline accredited to silver standard.

If you would like to tender for the installation please email Owen Griffith (Project Manager) at owen.griffith@nationaltrust.org.uk and request the full tender pack.
