District Heating Utility "Poltavateploenergo" has implemented a project, which was completed in autumn 2015. The project area includes a boiler house supplying heat and hot water to ten, mainly residential buildings but also a children's hospital and a school.The project concept was to:
(I) Introduce demand driven heat supply to customers, by installing individual heat substations with control of heat supply in relation to outdoor temperature in all buildings connected to the boiler house.
(II) Reduce losses in the heat distribution system by replacing all district heating pipelines in the area.
(III) Replace the old boilers with new efficient condensing boilers with capacity to adapt the heat production to the heat demand.
The demonstration project in Oleksandria was completed in autumn 2015. The project includes:
The demonstration project in Kamyanets-Podilskyi was completed in autumn 2015. The project included:
(i) Installation of 22 modern prefabricated individual heating substations (IHSs) with brazed heat exchangers, downsized control valves and heat meters in residential and public buildings supplied from a boiler house at Zhukova Street
(ii) Retrofit and balancing of building internal heating systems (iii) Installation of frequency controlled network distribution pump for variable flow.

The demonstration project in Vinnytsia was completed in spring 2015. The project area includes eleven residential building blocks and a hospital. Heat and hot water to the buildings are provided from two boiler houses. The project concept was to
Project results and achievements
The project in Vinnytsia demonstrates what can be achieved by analysing the district heating system as a whole and by using best practices in technical design and project implementation. By introduction of individual heating substations and new modern district heating pipelines the losses are reduced, which in turn results in less capacity demand for heating and hot water preparation. As a result the heat load could be connected to a more efficient boiler house with excess capacity and an inefficient boiler house could be taken out of operation. All in all, energy savings in the order of 30 % are expected. Apart from the improved services to the about 2100 residents living in the buildings, the project is profitable for the utility, with an expected pay-back time of about 5 years. The use of modern design and implementation practices was essential for the project outcome, challenging established norms, practices and ways of thinking.
The demonstration project in Ivano-Frankivsk was completed in 2016. The project includes:
