At Helec we can design, install and maintain communal heating systems for commercial and domestic developments looking to increase fuel efficiency and reduce CO2 emissions.

We can assist you with all aspects of district heating from feasibility studies to plant room design and installation. Contact us today to discuss your project.

Advantages of Communal Heating

District heating provides a wide range of benefits for business and end users.

District heating schemes help new developments meet BREEAM targets and are also encouraged through local town planning.

Communal boiler systems provide significant carbon reductions compared to other energy sources. The table below compares district heating scheme emissions to single domestic heating systems.

 District heating CO2 Emissions (G/KwH) Individual heating CO2 Emissions (G/KwH)
 Gas CHP 10 Gas Boilers 260
 Biomass 30 Electric Heating 850
 Oil 20 Oil Boiler 350
 Biogas CHP 360 Heat Pumps 300

Communal bolers also offer other advantages including:

  • Reduced maintenance and increased lifespan with a typical system lasting 25 years compared to 15 for gas boilers.
  • Combined Heat and Power reduces energy costs to individual properties
  • Removing gas boilers reduces or circumvents safety inspection costs

How Communal Heating Systems Work

A communal heating or District heating system supplies thermal heat and domestic hot water to a number of dwellings from a common heat source generally within a single plant room. It may comprise of, for example, a system heating a block of apartments or a larger scale system heating many buildings via a district heating scheme.

This type of system uses significantly less energy when compared to individual gas fired boilers and with the combination of renewable energy sources, carbon emissions are greatly reduced.
Combined Heat & Power (CHP) units are well suited to this application as they are usually designed and sized to be the “lead boiler” in the plant room providing thermal heat whilst also generating low cost electricity.

Heat interface units in each apartment or home are connected to the central heat source and provide Independent, hot water and heating for each residence. 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.

Energy Meters

Within each heat interface unit, in-built energy meters accurately monitor and record the energy used to provide heating and hot water for each dwelling in the communal heating system. These meters provide actual heat consumption figures for each home and the end user is billed for only what they use.
