Heat Network

Communal & District Heat Networks

A communal or district heat network system supplies heat to a number of dwellings from a common source. It may comprise of, for example, a single plant room supplying a block of apartments or a larger scale system heating many buildings.

What is Communal or District Heating?

A communal or district heat network supplies a number of customers with thermal energy for heating and/or production of domestic hot water.

System water is heated in a central plant, distributed to the end users via underground or above ground pipework and energy transferred to the final customer via a heat interface unit (or other).

Types of Heat Network

The size of a heat network can differ greatly, therefore the following two types have been defined:

Communal heating – a central plant supplies thermal energy to a number of final customers within one building.

District heating – a central plant supplies thermal energy to a number of final customers in more than one building.

Delivery of low carbon heating

A well designed and maintained heat network uses significantly less energy when compared to individual gas-fired boilers and with the combination of renewable energy sources, carbon emissions are greatly reduced.

There are currently around 17’000 heat networks registered in the UK, serving domestic, public and commercial buildings. However, this is set to increase, with the Department for Business, Energy and Industrial Strategy (BEIS) promoting the use of heat networks and stating that they are key in the delivery of low carbon heating throughout the UK.

In recognition of this BEIS’s £320M Heat Networks Investment Project (HNIP) capital investment programme is expected to support up to 200 projects by 2021 through grants and loans and other mechanisms and to lever in up to £2bn of wider investment, reducing bills, cutting carbon and forming a key part of wider urban regeneration in many locations. Also supported by the Heat Networks Delivery Unit (HNDU), which was set up to provide support (grant funding and guidance) to local authorities in England and Wales to progress the development stages of heat networks projects from heat mapping through to early commercialisation.

Heat Interface Units

Heat interface units (HIU’s) in each apartment or home are connected to a central heat source and provide independent hot water and heating for each residence connected to the heat network. This removes the requirement for individual boilers and a gas supply in each home.

Providing the end user with the same autonomy as if they had their own boiler and tank, and just as with their own independent heat source they pay for only the energy they use.

Metering & Billing Solutions

When designing, installing or operating a heat network, energy metering, monitoring and billing should be a key consideration from the outset, to ensure the best solution is provided for the residents and the building owner or manager.

Evinox are a leading specialist in energy metering and billing. Our services are versatile, ranging from data only, through to a Pre-payment system, or a complete remote billing solution using BUS / Ethernet communication to provide the end user with a fully itemised energy bill.
