Centralised system - Import export

District heating systems include a centralised energy centre which then distributes the heat through a network of insulated pipes to the buildings which are connected to the network. The network of pipework consists of a flow and return loop which passes each building. Colloide uses local substations in each building to control the flow of water from the district heating pipework loop through each substation and this flow is used to generate heat in the local building. The central energy centres are generally designed to have more than one energy source, which allows the plant operator to select the most cost efficient and sustainable way of providing the energy needed with the energy sources being brought on and off line to meet demand. We design and build the district heating and cooling networks to include the pumps, pipework, thermal stores, instrumentation, control systems, local substations, heat exchangers and communication through a central control system.
