HEATING & HOT WATER District heating and the power of the HIU
Charlie Mowbray, commercial product manager, Groupe Atlantic UK, ROI & NA, explores the role of heat networks and the role they can play on the pathway to Net Zero

ecarbonising heating and hot water in buildings is an existential challenge for our industry, but one solution that is set for a resurgence is district heating, or heat networks,
thanks to the energy efficiencies that can be achieved and the scalability on offer. Around 500,000 UK properties are currently connected to district heating networks but the government’s Clean Growth Strategy predicts this could rise to more than five million by 2050. To help make this happen, £288 million has been committed to support the development of new heat networks through the Green Heat Network Fund (GHNF), which is open to the public, private and third sector and runs until 2025.
But what is district heating and how does it work?
A district heating system delivers thermal energy in the form of hot water from a central source to end users using a network of insulated pipes. This network could be designed to serve a single block of flats or an entire city. Every district heating system has three main elements: 1. The energy centre sits at the heart of a heat network, heating the hot water that is distributed around the system. Although energy centres can use almost any heat source, to take advantage of the GHNF low carbon heat sources must be used.
2. The energy centre connects to the distribution network, the insulated pipes that deliver hot water to end users.
