Core 364 – The UK’s largest gas replacement programme with ground source heat pumps

In this video, energy and regeneration specialist, ENGIE discusses delivering the ‘Core 364Gentoo Group project; enlisting Kensa Contracting as their specialist ground source heat pump delivery partner in this innovative programme which will see gas displaced by 364 ground source heat pumps across 7 tower blocks in Sunderland.

An underground aquifer, accessed via open loop boreholes, will provide the heat source for individual ‘Shoebox’ ground source heat pump in each flat connected to a fifth generation district heating system of ambient shared ground loop arrays.

The ambient system prevents heat losses, overcomes overheating in the tower block communal areas, and boosts the system efficiency.

The decentralised heat pumps will provide heating independence to the tenants, with each able to shop around for the cheapest electricity deal, whilst reducing carbon emissions by an estimated 70% per year (420 tonnes) and improving local air quality. As the grid further decarbonises, the carbon savings of the system will become even more pronounced.

In addition to the removal of the gas supply to the tower blocks, the Gentoo scheme will see further improvements including; the installation smart meters and sprinklers as well as upgrades to the incoming electricity supply, fire alarm and detection systems.
