Our project deserves to win because it shows that the energy transition of the challenging district-heated multi-family housing sector does not have to be slow, invasive, or costly. Surprising symbiosis: Rather than treating the heat pump as competition for the district heating network, we built a system in which both technologies work together - the heat pump takes over the cost-effective base load, while the network remains the guarantor of peak demand and comfort. Innovation in orchestration, not in the device: The project's true value lies not in a single heat pump, but in the proprietary EMS, which reconciles PV production, energy storage status, outdoor temperature, forecasted COP, and electricity and heat prices in real time - with the EMS architecture also enabling operation under variable-price (dynamic) tariffs - always selecting the cheapest and most efficient source. Convincing market validation: This is not a concept on paper - following the successful pilot, the investor ordered an identical system for two further buildings, and the solution is already operating in several dozen buildings across northern Poland. Hard numbers and scalability: -41% in the total cost of DHW (from PLN 36.35 to PLN 21.48/m³) and 15.01 fewer tonnes of CO2 per year in a single building - with a technical replication potential reaching approximately 250,000 multi-family buildings in Poland, representing nearly 5 GW of heating capacity and an estimated 2.9 million tonnes of CO2 avoided annually nationwide (based on national average emission factors for district heat and grid electricity).
