Heating Solutions for Multi-Story Buildings: An Expert's View
During an interview with political analyst Yuriy Romanenko, heating supply expert Volodymyr Anufriiev argued that heat pumps and solar panels are not optimal solutions for heating Kyiv's high-rise buildings during power blackouts. He cited physical limitations and a reliance on grid electricity as key obstacles to implementing these technologies in an urban environment. Anufriiev proposed an alternative: installing cogeneration plants that can provide both heat and electricity. This debate is critical as Ukraine's energy infrastructure faces sustained pressure.
Challenges of Implementing New Technologies
The expert noted that implementing this cogeneration solution would first require an assessment of the gas networks and the condition of the district heating systems. Volodymyr Anufriiev emphasized that:
“We need to evaluate the networks and identify points where we can locate cogeneration stations. This requires a medium-pressure gas point and the appropriate network infrastructure.” - Volodymyr Anufriiev
He also observed that it is crucial to determine if the network remains in its originally designed state, as it may have sustained damage.
Among the primary issues with deploying solar panels and heat pumps in apartment blocks, Anufriiev highlighted physical constraints, specifically the insufficient roof area to install the necessary number of panels. He noted that:
“If you look at references for cottage communities, they always have solar panels on top for generation. But when we move to multi-story buildings, such options are not suitable.” - Volodymyr Anufriiev
The expert also pointed out that 'each cell of a large battery storage system can consume up to 5 kW of electricity for heating to avoid overcooling.'
Cogeneration plants, which are already used successfully in Canada and were previously installed in Ukraine, could be an effective solution for supplying heat and power to high-rises. However, their implementation requires identifying suitable locations, considering dense urban development like in the Troieshchyna district. Volodymyr Anufriiev remarked: “The most painful question is: where do we place it?” This issue demands careful analysis and planning to effectively solve the heating problem in large cities.
In the context of an energy crisis caused by blackouts, the issue of efficiently heating multi-story buildings is becoming increasingly urgent. Implementing cogeneration plants could be one potential path to solving this problem, but it requires a detailed analysis of existing networks and infrastructure. Evaluating alternative technologies, including an assessment of their feasibility in specific urban conditions, will help find optimal solutions to ensure resident comfort during these challenging times.
