Community Heat Hub with GTC and Taylor Wimpey

Westland Heath, Sudbury, Suffolk is a major new development where GTC is delivering fully integrated multi-utilities infrastructure, including a zero-carbon heat network serving 950 homes and a new local school.

At the heart of the scheme is an award-winning Community Heat Hub powered by networked air source heat pumps, providing reliable, low-cost heating and hot water at scale. The system demonstrates how low-carbon heat networks can be successfully delivered beyond dense urban settings, offering a practical and future-ready solution for new communities.

Benefits:

Lower Costs. Faster Build.

• Lower build costs – significant savings vs. individual

Air Source Heat Pumps (ASHPs):

• Optimised efficiency – thermal stores balance peak demand
• Smarter Grid Use – reduces peak electrical site demand by up to 15%
• Space-saving – compact HIU replaces gas boiler; no cylinder or bulky outside unit Future Homes Standard compliant – cuts carbon by 75-80% from day one

Technology:

Efficient Design. Future-Ready.

• Low-temperature network – 60°C design with insulated polymer pipes
• Space-saving – compact HIU fits neatly indoors; no external ASHP
• No cylinder required – HIU delivers instant heating and hot water on demand
• Thermal stores – charge at night-time rates for low-cost heat at peak times
• Future-proof – ready for grid decarbonisation without retrofits
