Locally Led Innovative Low Carbon Heating Infrastructure

10:30am to 2:00pm
Enfield ground source heat pump tower blocks site - Site Office, DORSET HOUSE, 4 KETTERING ROAD, ENFIELD, EN3 6XA, United Kingdom
Renewable energy

See how Enfield Council is utilising innovative heating infrastructure in its housing stock to reduce its carbon emissions, improve air quality and lower fuel poverty.

This event will encompass talks and guided tours from Enfield Council, Kensa Contracting, and Energetik, spanning an award-winning district heating scheme featuring 400 ground source heat pumps in 8 tower blocks (Kensa Contracting), and London’s first publicly owned, publicly funded heat network.

Both projects have been featured as exemplars: in the Greater London Authority's ‘Low Carbon Heat: Heat Pumps in London’ report, and BEIS’ heat network guidance documents respectively.

This event is ideal for: local authorities; housing associations; M&E consultants; developers; district heating operators, and policy makers.

Site 1

Showcasing sustainable low carbon heating infrastructure at England’s largest district ground source system, delivered by Kensa Contracting & ENGIE:

Discover the key elements and benefits of England’s largest shared ground loop array ground source heat pump project.

Enfield Council and Kensa Contracting will guide you though the award-winning low-carbon site featuring the Renewable Heat Incentive supported retrofit of Kensa ground source heat pumps in 400 flats over eight tower blocks. 

Featuring individual ground source heat pumps in each dwelling connected to 16 “micro-districts” each supplying half a tower block, this showcase tour will demonstrate an alternative approach to district heating.

Replacing electric heating, the Kensa ground source heat pumps will save over 773tCO₂ per year, emit zero point of use NOx, SOx or particulate emissions, and give nearly £9 million in collective bill savings over the 40 year system lifetime.

During the presentation and tour, we will show you and explain:

  • What a Shared Ground Loop Array is
  • How a ground source heat pump works
  • A typical installation in a flat
  • The groundworks and pipework, including: borehole positions, manifolds, riser pipework
  • Replicability in retrofit and new build properties

Site 2

Learn about decentralised energy and the future of heating: Visit the Arnos Grove heat network, operated by Enfield Council’s energy company – Energetik

Energetik is developing a series of heat networks in Enfield that will supply low-carbon heating & hot water to over 15,000 homes and businesses. Each network is futureproofed and adaptable, so they can expand over time to supply a larger area.

The Arnos Grove heat network was Energetik’s first to go into operation in 2017. It’s a live example of how heat networks can deliver low carbon heat competitively with alternative fossil fuels, with a better service to customers.   

Join this tour to understand how Energetik is a different kind of energy company, and see for yourself the energy centre that supplies reliable, environmentally friendly heat to residents.

During the tour, we will show you and explain:

  • What a heat network is
  • The equipment that supplies the heating and hot water to homes
  • Energetik’s approach to technical standards, leading the way for the wider industry
  • Why heat networks are growing and their role in our future energy system
